Choice IQ readout
A monthly rate of 3.5% compounds to roughly 51.11% a year, which is far above almost any personal loan. Clearing this faster is usually the highest guaranteed return available to you.
- Paying the minimum due keeps the account current but barely touches the principal. It is a credit-score device, not a repayment plan.
- Compare a personal loan at 11% to 16% a year, or a balance transfer, against the roughly 40%+ effective rate here.
- Interest-free periods end the moment you carry a balance. New purchases start accruing interest immediately.
Tool guide
How to use this credit card interest calculator india
Credit card rates are quoted monthly, which makes them look far smaller than they are. A 3.5% monthly rate compounds to over 50% a year. This calculator converts the monthly rate to an effective annual one and works out how long your chosen payment takes to clear the balance - including telling you when the payment is too small to ever clear it.
Formula
Effective annual rate = (1 + monthly rate)^12 - 1. Each month: interest = balance x monthly rate, then balance = balance + interest - payment.

FAQ
Why is my credit card interest so high?
Because the rate is quoted per month. Multiply by twelve and compound it and a typical 3% to 3.75% monthly rate becomes 42% to 55% a year. It is among the most expensive borrowing available in India.
What happens if I only pay the minimum due?
The account stays current and your credit score is protected, but the balance reduces very slowly or not at all. The minimum due is designed to keep the account in good standing, not to repay the debt.
Should I take a personal loan to clear a credit card?
Often yes. Personal loans in India typically run 11% to 16% a year against 40%+ on cards. The saving is substantial provided you stop using the card afterwards, which is the part that usually fails.
