Credit card payoff calculator
See exactly when you'll be debt-free and how much interest you'll pay — then watch a little extra each month change both.
Each month, interest accrues on your balance at one-twelfth your APR, then your payment is applied — whatever's left after interest reduces the principal.
- Add interest for the month to the balance.
- Apply your payment; anything beyond that month's interest reduces principal.
- Repeat until the balance reaches $0.
Example: Using the example numbers below, this works out to a months to pay off: 6 yrs, with a total interest paid of $5,185.

See if there's a better option
You're on track to pay $5,185 in interest — a 0% balance-transfer card could erase most of it.
Checking won't affect your credit score.
Key takeaway: Interest is calculated on whatever balance you're carrying before your payment lands, so a card near the average U.S. rate of 24.35% can eat most of a small payment before it ever touches principal.
Why does my APR cost so much?
Your APR is the yearly interest rate your card charges on a balance you carry. Each month roughly one-twelfth of it is applied to what you owe, before your payment lands. Because the interest comes off the top, a smaller payment leaves less to reduce the actual balance — which is why high-APR debt can feel like it barely moves.
How do I pay it off faster?
Two levers move your payoff date: pay more each month, or lower the rate. Adding even a small amount to every payment goes entirely to principal, so it compounds in your favor for the rest of the payoff — see the extra payments calculator to put an exact number on that.
Lowering the rate has the same effect from the other side. A 0% balance-transfer card removes interest for a fixed window, so the whole payment reduces the balance — often enough to clear it before the promo ends. Run your own numbers on the balance transfer breakeven calculator before applying for one, since the transfer fee isn't always worth it.
How we calculate this
This calculator uses standard declining-balance amortization: each month, interest accrues on your current balance at one-twelfth your APR, then your payment is applied — whatever's left after interest reduces principal. We repeat that until the balance reaches $0. It's the same method your card issuer uses to calculate the interest on your statement, so the payoff date here should match reality as long as your APR and payment stay constant.
Frequently asked questions
How is my credit card payoff date calculated?
Each month, interest is added to your balance based on your APR, then your payment is applied. Whatever is left after interest reduces the principal. We repeat that month by month until the balance reaches $0 — the month that happens is your payoff date.
Why does paying only a little extra save so much?
Interest is charged on your remaining balance, so every extra dollar of principal you knock out stops accruing interest for the entire rest of the payoff. Early extra payments compound the most, which is why even $50–$100 more a month can cut years off the timeline.
What counts as the APR I should enter?
Use the purchase APR shown on your statement — it's the yearly rate your issuer charges on carried balances. If your card has different rates for purchases, transfers, and cash advances, enter the one that applies to the balance you're paying down.
