See exactly when you will be debt-free — and how much interest you save by paying more than the minimum.

A credit card pay off calculator does what a spreadsheet would take you an afternoon to build: it simulates your payoff month by month. Each month it adds one month of interest to every card, pays the minimums you entered, then throws every remaining dollar of your budget at one target card — the highest APR first (avalanche) or the smallest balance first (snowball). It repeats until every balance hits zero, then reports the month count, the calendar date and the total interest paid along the way.
The avalanche method attacks the highest interest rate first, so it always pays the least interest — it is the mathematically optimal choice. The snowball method clears the smallest balance first, which means you close out a whole card sooner; that early win keeps many people motivated long enough to finish. Our debt snowball worksheet walks through the snowball method with a copy-ready table you can fill in by hand. The comparison table above runs both strategies on your exact numbers, so you can see what the motivation premium actually costs you — often less than people expect.
Minimum payments are designed to keep the account current, not to get you out of debt. On a $5,000 balance at 24.99% APR, a $150 minimum barely covers the ~$104 of monthly interest at first — only about $46 attacks the balance. Run those minimums-only numbers and the payoff stretches to 58 months — nearly five years — costing more than $3,600 in interest on a $5,000 debt. Our payoff-time guide works through the full maths, including what happens at $200 and $300 a month.
Three simplifications keep the maths honest but simple. One: no new purchases — every card balance only shrinks, which is also the behaviour you need in real life while paying debt down. Two: fixed APRs and fixed minimums as you entered them; in reality minimums usually fall as balances shrink, so real payoffs can run slightly faster. Three: no fees, penalties or balance-transfer offers — a 0% balance transfer can beat both methods, but the transfer fee (typically 3–5%) belongs in the comparison. Treat the debt-free date as a planning estimate, not a promise.
A tool that projects when your credit card debt will reach zero. You enter each card's balance, APR and minimum payment plus the total you can pay per month, and it simulates the payoff month by month — reporting your debt-free date, total interest paid and a snowball vs avalanche comparison.
The avalanche (highest APR first) always costs less in interest — it is the mathematically best choice. The snowball (smallest balance first) closes a card sooner, which helps motivation. The comparison table above shows both on your numbers; if the interest difference is small, pick the method you will actually stick with.
Because most of the minimum goes to interest, not principal. On a $5,000 balance at 24.99% APR, a $150 minimum covers about $104 of interest first — only ~$46 reduces the debt. Paying just the minimums stretches that payoff to 58 months (nearly five years) and costs over $3,600 in interest on a $5,000 balance.
Enter the real total you can pay across all cards each month — at least the sum of your minimums, or the calculator will warn you. Every dollar above the minimums goes straight at principal on your target card, which is why even $50 extra a month can cut years off a payoff.
No. It assumes no new spending, fixed APRs and no fees — the behaviour you need while paying debt down. A 0% balance-transfer offer can beat both methods shown, but remember its transfer fee (usually 3–5%) when comparing.
