The Credit Card Interest Calculator shows the real cost of carrying a balance on your card. Enter your outstanding balance, the monthly interest rate, and how much you pay each month, and it works out how many months it takes to clear the debt, the total interest you pay, and the total amount you hand over.
Credit cards charge some of the highest interest rates around — typically 3% to 4% per month, which works out to 36%–48% a year. Seeing the numbers makes it clear why paying more than the minimum due matters so much. Everything runs in your browser.
How to use the credit card interest calculator
- Enter your outstanding card balance.
- Enter the monthly interest rate (most Indian cards charge 3%–4% a month).
- Enter how much you plan to pay each month.
- Read the time to clear, total interest, and how paying more would speed things up.
How credit card interest works
Interest is charged on your outstanding balance every month (banks usually compute it daily and bill it monthly). Each month the interest is added to your balance, then your payment is applied to the total. If your payment is smaller than the interest charged, the balance actually grows.
Worked example: a ₹50,000 balance at 3.5% a month, paying ₹5,000 each month, takes about 13 months to clear and costs roughly ₹12,633 in interest — so you repay about ₹62,633 in all.
The minimum-due trap
Paying only the “minimum amount due” (often about 5% of the balance) barely covers the interest, so the debt lingers for years and the interest piles up. The table below shows how the same ₹50,000 balance at 3.5% a month clears at different monthly payments — paying more cuts both the time and the interest dramatically.
Clearing a ₹50,000 balance at 3.5% per month, by monthly payment.
| Monthly payment | Time to clear | Total interest |
|---|---|---|
| ₹2,000 | 5 yr 1 mo | ₹70,901 |
| ₹2,500 | 2 yr 11 mo | ₹37,494 |
| ₹5,000 | 1 yr 1 mo | ₹12,633 |
| ₹7,500 | 8 months | ₹7,953 |
| ₹10,000 | 6 months | ₹5,961 |
How to clear card debt faster
- Always pay more than the minimum due — ideally the full statement balance.
- Target the highest-interest card first if you have several.
- Consider a balance transfer to a lower-rate card, or converting a big purchase to an EMI, if the rate is genuinely lower after fees.
- Avoid new spending on the card until the balance is cleared, since fresh purchases also start accruing interest.
Frequently Asked Questions
How is credit card interest calculated?
Interest is charged on your outstanding balance each month (computed daily, billed monthly). At 3.5% a month, a ₹50,000 balance accrues about ₹1,750 of interest in the first month; your payment is then applied to the balance plus that interest.
What is the minimum-due trap?
The minimum amount due is often only about 5% of your balance, which barely covers the interest. Paying just the minimum keeps the balance high for years and can cost more in interest than the original purchase.
How can I pay off credit card debt faster?
Pay more than the minimum — ideally the full balance — target the highest-rate card first, stop new spending on the card, and consider a lower-rate balance transfer or EMI conversion if the effective rate is genuinely lower.
What interest rate do credit cards charge in India?
Most cards charge about 3% to 4% per month, which is roughly 36% to 48% a year — far higher than loans or EMIs, which is why carrying a balance is expensive.
