Frequently Asked Questions

Are these calculators free?
Yes, all calculators are completely free with no ads, no logins, and no tracking. Just open and calculate.
How accurate are the results?
Our calculators use standard financial formulas (reducing balance EMI, IRR, amortization). Results are indicative — final numbers depend on your lender's exact terms, fees, and policies. We show effective APR and total cost to give you the full picture, not just the headline number.
Do you store my financial data?
No. All calculations run entirely in your browser using JavaScript. Nothing is sent to any server. Your financial data never leaves your device. You can verify this in your browser's network tab.
Why 6 categories? Most sites just have an EMI calculator.
Because EMI is just one number. The real cost of a vehicle includes total cost of ownership (fuel, insurance, maintenance, depreciation), trade-in timing, risk assessment, EV transition economics, and tax implications. We cover the full lifecycle — not just the loan.
Which calculator should I start with?
Start with the Affordability Index to see if you can comfortably afford a car. Then use the EMI Calculator to plan payments, Loan Eligibility to see how much you can borrow, and Credit Score Impact Simulator to understand how a car loan affects your credit. Check True Monthly Ownership Cost for the real monthly picture beyond EMI. Planning to prepay? Use Prepayment Savings to see how much you save. Choosing between fuel types? Run Petrol vs Diesel Break-even. Budget for coverage with Insurance Premium Estimator. Track value loss with the Depreciation Curve Visualizer. Considering electric? Use EV Charging Cost and ICE to EV Transition ROI together. Upgrading? Try Trade-Up Readiness. Buying used? Run the Used Car Risk Index. And always check Road Tax by State before finalizing your on-road price.
When will all 45 calculators be live?
45 calculators are live right now across all 6 categories. Every tool from EMI and eligibility through ownership cost, trade intelligence, risk assessment, EV-specific analysis, and tax compliance is now available. One remaining calculator (EV Resale Value by Battery Health) will launch soon.
