How to use this debt payoff calculator
List each debt you owe — credit cards, store cards, a car loan, a personal loan — with its current balance, interest rate (APR), and the minimum payment your lender requires. Don't know your interest rate? Pick the debt type and the calculator fills in a typical current rate for that kind of debt. Then add any extra amount you can put toward debt each month. The calculator pays the minimum on everything and throws the extra at one target debt at a time, rolling each freed-up payment onto the next debt as balances disappear. Just tackling plastic? Use the dedicated credit card payoff calculator.
Snowball vs. avalanche, in one minute
Both methods pay minimums on every debt and attack one debt with your extra money. They differ only in which debt goes first:
- Avalanche targets the highest interest rate first. This is the cheapest path — you pay the least total interest and usually finish soonest.
- Snowball targets the smallest balance first. You pay a little more interest, but you clear whole debts faster, which keeps a lot of people motivated.
There's no universally right answer. If the interest difference is small, the snowball's momentum can be worth it. If it's large, the avalanche keeps more money in your pocket. Read the full debt snowball vs. avalanche comparison →
The fastest ways to pay off debt sooner
- Don't fall into the minimum-payment trap. Paying only what your lender requires barely touches principal on high-rate debt — especially credit cards. Read how the trap works and how to escape →
- Add even a small extra payment. Because extra money attacks principal directly, $50–$100 more a month can cut months — or years — off your timeline. Change the “extra payment” box above to see it.
- Lower your rate. A 0% balance-transfer card or a lower-rate consolidation loan means more of every payment kills principal instead of interest.
- Keep the total payment constant. When one debt is paid off, don't pocket that payment — roll it onto the next debt. That rollover is what makes both methods accelerate over time.
Frequently asked questions
Is the debt snowball or avalanche method better?
The avalanche method (paying the highest-APR debt first) always costs the least interest and is usually the fastest. The snowball method (paying the smallest balance first) costs a little more but gives you an early win that many people find easier to stick with. This calculator shows both so you can decide whether the motivation is worth the extra interest.
What is the debt avalanche method?
You pay the minimum on every debt, then put every extra dollar toward the debt with the highest interest rate. When that one is gone, its payment rolls onto the next-highest rate. It minimizes the total interest you pay.
What is the debt snowball method?
You pay the minimum on every debt, then put every extra dollar toward the debt with the smallest balance. When it's cleared, that payment rolls onto the next-smallest. You get debts fully paid off sooner, which builds momentum.
Does this debt payoff calculator save my financial information?
No. Every calculation runs in your browser. Nothing you type is sent to a server, stored, or shared.
How accurate is the payoff estimate?
It assumes a fixed APR, on-time payments, and that you keep paying the same total amount every month. Real-world results vary with rate changes, fees, and missed payments, so treat the numbers as a solid estimate, not a guarantee.
