Debt Payoff Calculator: See Your Timeline and Total Cost
How long will it take to pay off your credit card debt? Enter your balance, interest rate, and monthly payment to see your estimated payoff timeline, what it’ll cost in interest, and which payoff strategy gets you there faster.
How to use this calculator
Start by entering the balance you want to pay off and the interest rate (APR) on that credit card. You’ll find the APR on your monthly statement or in your account online — most cards fall between 18% and 29%.
Then choose how you pay: enter a set amount you pay each month to see your estimated payoff timeline, or pick a minimum-payment method to see how long payoff takes, and what it costs, when you pay just the minimum each month. You only need one of the two — but if you fill in both, we’ll show you the two side by side.
Have more than one card? Switch to “Multiple cards.” Start with the total you can put toward all of them each month, then add each card’s balance, APR, and minimum-payment method. Leave the total blank to see how long paying only the minimums would take — or enter a total to compare two payoff strategies, avalanche and snowball, side by side. If you pay a specific amount on one particular card, you can set that on the card itself.
How to read your results
Your results show how long it will take to become debt-free, the date you’d make that final payment, the total interest you’ll pay along the way, and the total amount you’ll pay overall (your original balance plus all that interest).
If your timeline looks longer than you expected, you’re not imagining it. When you make a minimum payment that shrinks as your balance drops, most of each payment goes toward interest rather than the balance itself, which stretches the payoff out for years. We explain exactly why that happens in The Minimum Payment Trap.
If you filled in both a set monthly payment and a minimum-payment method for one card, you’ll see those two compared side by side, with the difference in time and interest spelled out underneath.
If you entered multiple cards and a total monthly payment, you’ll also see two payoff strategies compared side by side. They reach the finish line differently, and we break down which one tends to fit which kind of person in Avalanche vs. Snowball. For each strategy you’ll also see the order it pays your cards off in, and roughly when each one clears.
How this calculator works
Here’s exactly how the calculator arrives at these numbers.
The interest. Each month, we calculate interest on your current balance using your APR divided by 12. So a $10,000 balance at 24% APR accrues about $200 in interest that month ($10,000 × 24% ÷ 12). That interest is added before your payment is applied.
The payment. If you tell us a set monthly payment, we use that figure every month. If you’re looking at a minimum-only payoff instead, we use the minimum-payment method you select — a percentage of your current balance, or 1% or 2% plus that month’s interest — with a floor of $25, recalculated every month as your balance falls. This is a big reason minimum-only payoff takes so long: as your balance drops, the required minimum drops right along with it, so less and less goes toward the principal each month.
The payoff. Each month we subtract that month’s interest from your payment; whatever’s left reduces your balance. We repeat this month by month until the balance reaches zero, then total up the time and interest.
These results are estimates. Real accounts vary, interest can compound differently, and your card’s exact terms may differ from the numbers you enter, so treat the numbers as a close guide rather than an exact prediction. For a worked real-world example of how long a large balance can take at the minimum, see How Long Does It Take to Pay Off a Credit Card.
This calculator is for educational estimates only. It’s based on the balance, interest rate, and payment details you enter. For a minimum-only payoff, the minimum is recalculated each month using the method you choose (never less than $25). Your actual rate, minimum payment, and payoff timeline will differ.
Frequently asked questions
How accurate is this calculator?
It gives an estimate, not an exact figure. It uses standard amortization math, but real accounts can vary in how interest is applied, and your card’s exact terms may differ from the numbers you enter. The more precise your inputs, the more accurate your result.
How does it calculate the minimum payment?
You choose how the minimum is calculated: a percentage of your current balance (from 1% to 5%), or 1% or 2% plus that month’s interest. Whichever you pick, it’s recalculated each month as your balance drops, with a floor of $25. Your card’s exact formula may differ.
Why is my payoff timeline so long?
Because when you pay only the minimum, most of each payment goes toward interest rather than the balance — and as the balance falls, the minimum falls too, so progress keeps slowing down. On a large balance this can stretch payoff out for decades.
Should I use the avalanche or snowball method?
Avalanche (paying highest-interest debt first) saves you the most money; snowball (paying smallest balance first) gives you quicker early wins that many people find motivating. The best one is the one you’ll actually stick with — we compare them in detail in Avalanche vs. Snowball.
What if I can’t afford to pay more than the minimum?
That’s a real and common situation, and it doesn’t mean you’ve done anything wrong — with high balances, the math is genuinely stacked against you. If your debt feels unmanageable no matter what you do, it may be worth looking into what options you have to get out of debt faster.
