Chapter 7 — Trial Balance

Every business transaction is first recorded in the journal or in a subsidiary book and is then posted to the ledger. In the ledger each account is balanced at the end of a period, which may be a month, a quarter or a year. The trial balance is a statement in which the balances of all the ledger accounts, including the cash book balances, are listed on a particular date, with debit balances in one column and credit balances in another. It is prepared to test whether the postings have been made with arithmetical accuracy.

The idea rests on the dual aspect principle. For every transaction the total amount debited equals the total amount credited. If every entry has been posted correctly, the sum of all debit balances in the ledger must equal the sum of all credit balances. Spicer and Pegler described the trial balance as a list of all the balances standing on the ledger accounts and the cash book of a concern at any given date. J. R. Batliboi called it a statement prepared with the debit and credit balances of ledger accounts to test the arithmetical accuracy of the books.

Three points follow from the definition. First, the trial balance is a statement and not an account. It is not part of the double entry system; no entry is passed to prepare it and it has no ledger folio. Second, it is prepared on a particular date, so its heading reads, for example, Trial Balance of Sri Rama Traders as on 31st March 2026. Third, it contains every account that has a balance; an account whose two sides are equal has a nil balance and is left out.

The trial balance is usually prepared at the end of the accounting year before the final accounts are drawn, but a careful accountant may prepare it monthly so that a difference is traced while the transactions are still fresh. In computerised accounting the software prepares it at any moment on demand, yet the logic taught here is exactly what the software performs.

A student should remember the word trial. The statement tries the books; it does not certify them. Agreement of the two totals is evidence that the arithmetic of posting and balancing is consistent, but it is not conclusive proof that every transaction has been recorded in the right account or for the right amount. The later topics of this chapter examine that limitation in detail.

The features of a trial balance are easily listed. It is a statement, not an account. It is prepared on a particular date. It contains the balances or totals of all ledger accounts and of the cash book. It has two money columns, debit and credit, and the total of the two columns must be equal. It is prepared after the ledger accounts are balanced and before the final accounts are drawn. It is a working paper for the accountant and is not shown to outsiders in the way a balance sheet is.

The objectives of preparing a trial balance are the reasons a business takes the trouble to prepare it.

• To test arithmetical accuracy. When the totals agree, the accountant knows that for every debit posted an equal credit has been posted, that the totalling of accounts is correct and that the balances have been carried correctly. This is the primary objective.
• To help in locating errors. If the totals disagree, the accountant knows an error exists and starts the search at once, before the error is buried under further entries. The size of the difference itself gives clues, as a later topic shows.
• To provide a basis for final accounts. The trading account, the profit and loss account and the balance sheet are all prepared from the trial balance. Nominal accounts go to the trading and profit and loss account; real and personal accounts go to the balance sheet.
• To give a summary of the ledger. A ledger may run to hundreds of pages. The trial balance condenses it into one or two pages, so the owner can see at a glance the balance of every account.
• To make comparison possible. Trial balances of different dates can be placed side by side to compare, for instance, the sales or the expenses of two years.

There is also a practical objective in an examination setting: many problems in this course and in the final accounts chapters begin with a trial balance, so the ability to read one quickly is a skill in itself. A student who can say at once that Bills Payable is a liability and therefore a credit balance, or that Carriage Inwards is an expense and therefore a debit balance, will save time in every later chapter.

It should be stressed that the trial balance is a means and not an end. Its agreement is the accountant's signal to proceed to the next stage of the accounting cycle. Its disagreement is a signal to stop and search. Either way, it is the checkpoint that stands between the ledger and the financial statements.

A trial balance has a standard columnar format. Across the top is the heading, naming the business and the date. Below it are four columns: Serial Number, Name of the Account (Particulars), Ledger Folio, and the two money columns headed Debit Balance (Rs) and Credit Balance (Rs). Under the totals method the money columns are headed Debit Total and Credit Total instead; under the combined method there are four money columns.

The ledger folio column records the page of the ledger where each account appears, so that anyone can turn from the trial balance to the account in a moment. In examination answers this column is normally left blank because no ledger pages are given.

The order of accounts is not fixed by law, but a good order helps. One common order follows the ledger: cash and bank first, then personal accounts, then real accounts, then nominal accounts. Another common order groups accounts in the sequence in which they are needed for final accounts: opening stock, purchases, sales and returns first, then expenses and incomes, then assets, liabilities and capital. Either order is acceptable, provided every balance is included.

The totals are written at the foot of the money columns and ruled off with a double line. If the totals agree, the statement is complete. If they do not, the difference is entered on the shorter side against the words Suspense Account so that the columns are made to agree for the time being, and the search for the error begins.

Two small conventions matter in a written examination. Amounts are written in figures with Indian grouping (1,10,000 and not 110,000). Each account is written once, with one balance only; an account cannot appear in both columns. A student who has understood the format can prepare a trial balance for any set of balances in a few minutes; the only real difficulty is deciding the side, which the next topics address.

Under the totals method (also called the gross trial balance) the accountant does not balance the ledger accounts at all. Instead, the total of the debit side and the total of the credit side of every account are taken and written in the two columns of the trial balance. Since every debit posted in the ledger has an equal credit posted somewhere, the grand total of all debit sides must equal the grand total of all credit sides.

The procedure is: (1) add up the debit side of each account; (2) add up the credit side of each account; (3) enter both totals against the account name in the trial balance; (4) add each column; (5) compare the two column totals.

Consider a Cash account with receipts of Rs 40,000 on the debit side and payments of Rs 28,000 on the credit side. Under the totals method the trial balance shows Cash: Debit Total Rs 40,000, Credit Total Rs 28,000. Under the balances method it would show only the net balance of Rs 12,000 on the debit side. The two methods give the same arithmetic check because a balance is only the difference between the two totals.

The merits of the totals method are that it is quick, because no balancing is required, and that it shows the total volume of transactions in each account, which may be useful information in itself. Its demerits are that the figures are large and the statement is cluttered; that it does not show the balance of any account, which is what the final accounts need; and that an account with equal totals, whose balance is nil, still appears in the statement. For these reasons the totals method is rarely used in practice and is taught mainly for completeness and to make the logic of the check clear.

A point of care: in the totals method the total of the trial balance equals the total of the journal for the period only if all accounts are included and there were no opening balances. Where opening balances exist, they are already contained in the account totals.

In an examination, a question asking for a trial balance without specifying the method expects the balances method. The totals method is asked either by name or in a theory question that requires a comparison of the methods. A student should be able to convert from one to the other: total of the larger side minus total of the smaller side gives the balance, on the side of the larger total.

The balances method (net trial balance) is the method used in practice and in nearly every examination problem. Every ledger account is first balanced. The closing balance of each account is then written in the trial balance: a debit balance in the debit column, a credit balance in the credit column. Accounts with a nil balance are omitted. The two columns are then totalled and the totals compared.

The steps are: (1) balance every account in the ledger, including the cash book; (2) list every account that has a balance; (3) write debit balances in the debit column and credit balances in the credit column; (4) total the two columns; (5) if the totals agree, rule off; if not, look for the difference.

The merits of this method are strong. It shows the exact balance of each account, which is what the trading account, profit and loss account and balance sheet require, so the final accounts can be prepared straight from it. It is compact, because only one figure per account is written. It leaves out accounts that have closed themselves with a nil balance. It also gives the reader an immediate picture of the position of the business: how much is owed by debtors, how much is owed to creditors, what the expenses have been.

Its one demerit is that it depends on correct balancing; a mistake in balancing an account passes into the trial balance. This is why the balancing of accounts must be checked before the trial balance is drawn.

The greatest practical skill in the balances method is knowing on which side a given account's balance normally stands. The rule is easy to memorise:

• Debit balances: assets (cash, bank, stock, debtors, furniture, machinery, buildings, investments, bills receivable), expenses and losses (purchases, wages, salaries, rent, carriage, discount allowed, bad debts, depreciation), drawings, and sales returns.
• Credit balances: liabilities (creditors, bills payable, loans, outstanding expenses, bank overdraft), capital, incomes and gains (sales, commission received, interest received, discount received, rent received), reserves and provisions, and purchase returns.

When a problem gives a list of balances without saying which side each belongs to, the student must apply this rule. When a problem gives the balances with the sides already marked, the task is only to list, total and check. If a balance in a given list is shown on an unusual side, for example a debtor with a credit balance because he has overpaid, the student must accept the given side, since the account may genuinely have that balance.

The totals-cum-balances method (combined method) is a union of the two methods already described. The trial balance is ruled with four money columns: Debit Total, Credit Total, Debit Balance and Credit Balance. Against each account the accountant writes the total of its debit side, the total of its credit side, and then the balance in whichever of the last two columns is appropriate. All four columns are totalled; the two total columns must agree with each other and the two balance columns must agree with each other.

The purpose of this method is to combine the information given by the totals with the usefulness of the balances. The reader sees both the volume of transactions passing through an account and its net position. It also provides a check on the balancing itself, since the balance shown must equal the difference between the two totals on the same line, so an error in balancing a single account can be caught line by line.

The procedure is: (1) total both sides of every account; (2) enter the totals in the first pair of columns; (3) compute the difference and enter it in the debit balance column if the debit total is larger, or in the credit balance column if the credit total is larger; (4) total all four columns; (5) verify that Debit Total column = Credit Total column and Debit Balance column = Credit Balance column.

The merits are completeness and the double check. The demerits are that the statement becomes wide and laborious, doubling the writing, and that the extra information is rarely needed once the balances are known. In practice the method is almost never used, and in examinations it appears only in theory questions or in a problem that explicitly names it. A student who understands the other two methods can prepare it without difficulty, because it is simply both of them written side by side.

Whatever method is used, the logic is the same: the double entry system guarantees equality, and the trial balance verifies that the equality has survived the posting and balancing work of the period.

The most frequent error a beginner makes in a trial balance is placing a balance on the wrong side. The safest approach is to classify every account before writing it, using the golden rules already learnt and the nature of the account.

Personal accounts. A debtor is a person who has received a benefit from the business and owes money; his account has a debit balance. A creditor has given a benefit and is owed money; his account has a credit balance. Capital is the account of the owner, who has supplied funds; it has a credit balance. Drawings is the reduction of that capital; it has a debit balance. Bank is a personal account: a favourable balance (money in the bank) is a debit balance, a bank overdraft is a credit balance. Loans taken are credit balances; loans given are debit balances.

Real accounts. All assets, whether tangible like cash, stock, furniture, machinery, land and buildings, or intangible like goodwill, patents and trademarks, have debit balances, because the account is debited when the asset comes in. Bills receivable and investments are also assets with debit balances.

Nominal accounts. Expenses and losses are debited: purchases, wages, salaries, rent, insurance, carriage inwards, carriage outwards, advertising, printing and stationery, postage, bad debts, depreciation, discount allowed, interest paid, loss by fire. Incomes and gains are credited: sales, commission received, interest received, rent received, discount received, dividend received, profit on sale of an asset.

Returns. Sales returns (returns inward) reduce sales and carry a debit balance. Purchases returns (returns outward) reduce purchases and carry a credit balance. In the trial balance they are shown separately as gross figures; they are not deducted from sales or purchases.

Reserves and provisions. General reserve, reserve fund, provision for doubtful debts and provision for depreciation are credit balances, because they are amounts set aside out of profit or out of the value of an asset.

Stock. Opening stock is an asset brought forward and has a debit balance; it always appears in the trial balance. Closing stock normally does not appear, because it is valued after the books are closed; its treatment is covered in the next topic.

A memory aid used by many teachers is A-E-L-D on the debit side (Assets, Expenses, Losses, Drawings) and L-C-I-G on the credit side (Liabilities, Capital, Incomes, Gains). Whenever an item is unfamiliar, the student should ask: is it something the business owns or spends (debit), or something it owes or earns (credit)? That single question settles almost every case.

Some items require thought because they do not follow the simple pattern, or because the wording of a problem may confuse a student.

Opening stock and closing stock. Opening stock is the stock brought forward from the previous year. It stands in the ledger as a debit balance and always appears in the trial balance. Closing stock is normally valued by physical count after the books are closed and is not yet in any ledger account, so it does not appear in the trial balance; it is given separately as an adjustment. However, if the closing stock has already been recorded by an entry (Closing Stock A/c Dr, To Trading A/c or To Purchases A/c), then it does appear as a debit balance, and in that case the purchases figure is already adjusted. A problem that shows closing stock inside the trial balance is signalling that the entry has been passed; the closing stock then goes only to the balance sheet.

Adjusted purchases. When a trial balance shows Adjusted Purchases, it means Opening Stock + Purchases − Closing Stock has already been computed; the closing stock will also appear in the trial balance as an asset, and no opening stock will be listed.

Returns. Sales returns are a debit balance and purchases returns a credit balance, listed separately. Never net them against sales or purchases in the trial balance; netting is done later in the trading account.

Provisions and reserves. Provision for doubtful debts, provision for discount on debtors and provision for depreciation are credit balances. When a problem lists Sundry Debtors Rs 40,000 and Provision for Doubtful Debts Rs 2,000, both are listed, one debit and one credit; the provision is not deducted from debtors in the trial balance.

Accumulated depreciation. If the business keeps a Provision for Depreciation account, the asset appears at cost (debit) and the accumulated depreciation appears as a credit balance. If depreciation is written off directly, the asset appears at its written-down value and Depreciation of the year appears as an expense (debit).

Outstanding and prepaid items. Outstanding expenses that have been recorded are credit balances (liabilities); prepaid expenses that have been recorded are debit balances (assets); accrued income is a debit balance; income received in advance is a credit balance. If these are given below the trial balance as adjustments, they are not yet in the books and do not enter the trial balance.

Interest on capital and interest on drawings. If already recorded, interest on capital is an expense (debit) and interest on drawings is an income (credit).

Bad debts recovered is an income (credit). Loss by fire is a loss (debit). Goods distributed as free samples, if recorded, appear as an expense (debit) with purchases reduced accordingly.

The guiding principle in every case: an item enters the trial balance only if a ledger account holds that balance on the date of the trial balance. Anything valued or discovered after the books are closed is an adjustment and belongs to the next chapters.

The following worked problem shows the full procedure in the form a Telangana Intermediate examination expects. The balances were extracted from the books of Sri Krishna Traders on 31st March 2026:

Cash in hand 4,500; Cash at bank 26,000; Capital 1,00,000; Drawings 8,000; Purchases 1,20,000; Sales 1,95,000; Purchases returns 3,000; Sales returns 4,000; Opening stock 30,000; Sundry debtors 42,000; Sundry creditors 28,000; Wages 15,000; Salaries 18,000; Rent 9,000; Carriage inwards 2,500; Carriage outwards 1,500; Discount allowed 1,000; Discount received 800; Furniture 20,000; Machinery 60,000; Bad debts 1,300; Commission received 2,000; Bills receivable 6,000; Bills payable 9,000; Insurance 2,400; Bank loan 40,000; Interest on bank loan 3,600; Advertising 3,000.

Step 1 – classify. Assets: cash, bank, opening stock, debtors, furniture, machinery, bills receivable. Expenses and losses: purchases, wages, salaries, rent, carriage inwards, carriage outwards, discount allowed, bad debts, insurance, interest on loan, advertising. Drawings and sales returns: debit. Liabilities: creditors, bills payable, bank loan. Capital: credit. Incomes: sales, discount received, commission received. Purchases returns: credit.

Step 2 – list and total.

Step 3 – verify. Debit: 4,500 + 26,000 + 8,000 + 1,20,000 + 4,000 + 30,000 + 42,000 + 15,000 + 18,000 + 9,000 + 2,500 + 1,500 + 1,000 + 20,000 + 60,000 + 1,300 + 6,000 + 2,400 + 3,600 + 3,000 = 3,77,800. Credit: 1,00,000 + 1,95,000 + 3,000 + 28,000 + 800 + 2,000 + 9,000 + 40,000 = 3,77,800. The trial balance agrees.

When the totals do not agree in an examination problem, the usual cause is a balance placed on the wrong side, and the difference will then be exactly twice that balance. The student should check for that pattern first, before rechecking the addition.

A trial balance disagrees whenever an error breaks the equality of debits and credits. Such errors are said to be disclosed by the trial balance, meaning that the disagreement reveals their existence even though it does not say where they are. The main types are:

• Wrong totalling of a subsidiary book. If the Purchases Book is over-cast by Rs 1,000, the Purchases account is debited with Rs 1,000 too much while the individual creditors are credited with the correct amounts. The debit column of the trial balance exceeds the credit column by Rs 1,000.
• Posting to the wrong side of an account. A receipt of Rs 500 from Mohan credited to cash and posted to the debit of Mohan's account instead of the credit. Both accounts now have a debit entry; the trial balance differs by Rs 1,000, twice the amount.
• Posting with a wrong amount. Sales of Rs 2,300 to Kiran entered in the Sales Book correctly but posted to Kiran's account as Rs 3,200. The debits exceed the credits by Rs 900.
• Posting only one aspect. Salaries of Rs 4,000 paid, credited in the cash book, but not posted to the Salaries account at all. Credits exceed debits by Rs 4,000.
• Posting twice on one side. Rent of Rs 1,500 posted to the Rent account twice. Debits exceed credits by Rs 1,500.
• Wrong balancing of an account. Debtor's account with Dr total 9,000 and Cr total 3,500 balanced as 6,500 instead of 5,500. The debit column is Rs 1,000 too high.
• Wrong carry-forward or wrong totalling of the trial balance itself. A column added wrongly or a balance copied wrongly into the trial balance.
• Omitting a balance from the trial balance. The ledger is correct but one account is left out of the list; the difference equals that balance.

Notice that in every one of these cases only one side of the double entry is affected, or the two sides are affected by different amounts. That is the defining feature of a disclosed error: it is one-sided. The trial balance is a mirror that reflects one-sided errors immediately.

The size of the difference is a clue. A difference that is exactly one balance suggests an omission. A difference that is twice a balance suggests wrong-side posting. A difference divisible by 9 often indicates a transposition of digits (2,300 written as 3,200 gives 900; 56 written as 65 gives 9). A difference of 10, 100 or 1,000 suggests an addition slip. These clues do not replace a systematic search, but they tell the accountant where to look first.

These errors are corrected as soon as they are found, and if the statement had been agreed with a suspense account, the suspense account is reduced by each correction until it closes.

The agreement of a trial balance proves only that the debits equal the credits. Any error that keeps the two sides equal slips through unnoticed. Such errors are said to be not disclosed by the trial balance. They are the reason the statement is called a trial and not a proof. The classes are:

• Errors of omission. A transaction is left out of the books entirely. Goods sold to Prasad for Rs 5,000 are never entered in the Sales Book. Neither the Sales account nor Prasad's account is affected, so both columns are short by the same amount and the totals still agree.
• Errors of commission. An entry is made in the wrong account of the same class or with the wrong amount on both sides. Rs 2,000 received from Ramesh credited to the account of Rajesh; or a purchase of Rs 3,400 entered in the Purchases Book as Rs 4,300 and posted at 4,300 on both sides. The debit and credit still match.
• Errors of principle. A transaction is recorded against the fundamental rules of accounting, typically confusing capital and revenue. Purchase of a machine for Rs 50,000 debited to Purchases account instead of Machinery account; repairs to a building debited to Building account. The amount is equal on both sides, so the trial balance agrees, but profit and asset values are wrong.
• Compensating errors. Two or more errors whose effects cancel. The Sales Book is overcast by Rs 1,000 and, quite independently, the Purchases Book is also overcast by Rs 1,000. The extra credit to sales offsets the extra debit to purchases.
• Errors of duplication. A transaction is recorded twice in the journal and posted twice. Both sides are inflated equally.
• Wrong entry in the book of original entry. If the wrong figure is written in the journal or a subsidiary book and then posted faithfully, both accounts carry the same wrong amount.

The common thread is that these errors are two-sided: they affect a debit and a credit equally, or they affect two accounts on the same side by offsetting amounts. The trial balance cannot see them because it only compares totals.

The consequence for a business is serious. An agreed trial balance can conceal an overstated profit, an understated asset or a debtor who is being chased for money he has already paid. These errors are found by other means: checking the vouchers against the books, reconciling statements received from creditors and sent to debtors, reviewing the classification of large items, and the audit. When found, they are corrected through rectification entries, which form the subject of the next chapter.

An examination question often asks the student to list the errors not disclosed, with one example each. A student should be able to give a fresh example of each type rather than only the ones memorised, because the examiner may give a transaction and ask whether the trial balance would disclose the error.

When the two totals of a trial balance disagree, the accountant follows a systematic search rather than rereading the whole ledger at random. The recommended sequence is:

• Re-add both columns of the trial balance. A slip in addition is the commonest cause.
• Compute the exact difference and test it: is it one balance (omission), twice a balance (wrong side), divisible by 9 (transposition), or a round figure (addition slip)?
• Check that every ledger balance, including cash and bank, has been copied into the trial balance, on the correct side, with the correct figure.
• Check the balancing of every account, especially those with many entries.
• Check the totals of the subsidiary books: Purchases Book, Sales Book, Returns Books, Cash Book.
• Check the posting of every entry from the subsidiary books to the ledger, ticking each as it is verified.
• Check the opening balances brought forward from the previous year's balance sheet.

If the error is still not found and the final accounts must be prepared, the difference is placed temporarily in a Suspense Account. If the debit column is short, Suspense Account is given a debit balance equal to the difference; if the credit column is short, a credit balance. The trial balance is thus forced to agree, and the final accounts are prepared. The suspense balance is shown in the balance sheet on the assets side if debit, on the liabilities side if credit, until the errors are found.

As each error is discovered, a rectifying journal entry is passed, one side of which is the Suspense Account. When all the errors that caused the difference have been corrected, the Suspense Account balance becomes nil and the account closes automatically. If a balance remains, some error is still hidden.

Illustration. The trial balance of a firm shows debit total Rs 2,50,000 and credit total Rs 2,48,000. The credit column is short by Rs 2,000, so Suspense Account Rs 2,000 is written in the credit column. Later it is found that (a) the Sales Book was undercast by Rs 1,500 and (b) Rs 500 discount received was posted to the debit of Discount account. Rectification: (a) Suspense A/c Dr 1,500, To Sales A/c 1,500; (b) Suspense A/c Dr 1,000, To Discount received A/c 1,000. The two debits to Suspense total Rs 2,000, closing the account.

It must be understood that the suspense account is a device of convenience, not a cure. Two safeguards apply: the search must continue, and the suspense balance must never be allowed to persist from year to year. Auditors treat a lingering suspense balance as a sign of poor book-keeping.

The detailed rules of rectification, including errors found after the final accounts are drawn, belong to the next chapter; here the student needs only to see that the suspense account is the natural continuation of the trial balance check.

Having seen what the trial balance does and does not detect, the student can weigh its limitations against its importance.

Limitations. The trial balance does not prove that the books are free of error; errors of omission, commission, principle, compensating errors and duplication all pass through an agreed trial balance. It does not prove that every transaction has been recorded in the correct account or classified correctly as capital or revenue. It cannot be prepared unless the double entry system has been followed throughout; a business keeping single entry records cannot draw one. It is a statement of balances on one date and gives no information about the transactions behind them. It cannot detect a wrong entry in the book of original entry. Finally, its agreement can lull an accountant into a false sense of security, so that further checking is neglected.

Importance. Despite these limitations the trial balance is indispensable. It is the only routine check on the arithmetical accuracy of a whole period's posting and balancing. It catches the majority of clerical mistakes, which are one-sided, at the earliest possible moment. It summarises the ledger on one page and thereby forms the direct source for the trading account, profit and loss account and balance sheet; without it the final accounts would have to be built from hundreds of individual accounts. It provides a permanent record of balances that can be compared across periods and used by the auditor. It also disciplines the accountant: the habit of drawing a trial balance monthly keeps the ledger balanced and the search for differences short.

The trial balance and the balance sheet. Students sometimes confuse the two. The trial balance is a list of all ledger balances, including nominal accounts, prepared to test accuracy, drawn before the final accounts and not shown to outsiders. The balance sheet is a statement of assets and liabilities only, prepared to show financial position, drawn after the profit and loss account and forming part of the published accounts. The trial balance has debit and credit columns; the balance sheet has assets and liabilities sides. The trial balance includes closing stock only if an entry has been passed; the balance sheet always includes it. The trial balance is not compulsory; the balance sheet is necessary for every business.

Trial balance and the accounting cycle. The chain runs: transaction → voucher → journal or subsidiary book → ledger → trial balance → adjustments → trading and profit and loss account → balance sheet. The trial balance is the point at which the recording phase ends and the reporting phase begins. Everything after it uses its figures; everything before it is tested by it. That position explains why the Telangana Intermediate syllabus places this chapter immediately before final accounts.
