In one line
If supply is more than demand, prices usually fall because there are more goods than people want to buy.
The rule
When supply is greater than demand, the price of the product tends to decrease until demand and supply become equal.
Let's understand it simply
Imagine you are at a mango stall in the market. The seller has 100 mangoes, but only 30 people want to buy them. There are more mangoes than buyers. The seller does not want the mangoes to spoil, so he lowers the price. This makes more people interested in buying, or the seller sells off the extra mangoes quickly. So, when there is extra supply, prices go down.
How it works
Producers bring a large quantity of goods to the market (high supply).
Fewer people want to buy (low demand).
Goods start piling up because not enough people are buying.
Sellers lower prices to attract more buyers and clear their stock.
As prices drop, more people may buy, and supply and demand move towards balance.
What happens when supply is more than demand
Too many goods in the market
Not enough buyers
Prices fall
More people start buying
Supply and demand move towards balance
The story behind it
This idea is a basic part of economics and has been observed for hundreds of years. Economists like Adam Smith noticed that prices in markets change depending on how much is available and how much people want. The problem they were solving was: How do prices get decided in a busy market?
Where you see it in real life
Vegetable markets after a bumper harvest: Too many tomatoes → not enough buyers → tomato prices crash.
Diwali crackers after the festival: Shops have leftover stock → demand drops → prices fall.
End-of-season clothing sales: Shops have unsold clothes → fewer buyers → big discounts.
Fish markets in the morning: Lots of fish arrive → not all get sold → prices drop by evening.
Why it matters
Helps you understand why prices change in the market.
Useful for farmers, shopkeepers, and buyers to plan when to sell or buy.
Important for exams and higher studies in economics.
Businesses use this idea to avoid overproducing goods.
Common mistakes
Thinking prices always stay the same, no matter the supply or demand. In reality, prices change.
Believing that more supply is always good for sellers. Too much supply can mean lower profits.
Remember it
When goods are plenty but buyers are few, prices drop — just like mangoes at the end of the day in the market.
Check yourself
If there are 100 apples but only 50 buyers, what will likely happen to the price?
The price will go down because supply is more than demand.
Why do shops give discounts at the end of a season?
Because supply is more than demand; they want to sell leftover stock.
What is a common mistake students make about supply and demand?
They think prices stay the same even if supply is high, but prices usually fall.
Quick recap
When supply is more than demand, prices usually go down.
Sellers lower prices to attract buyers and clear stock.
This happens in markets, shops, and even with festival goods.
Understanding this helps you know when to buy or sell.
