How this calculator works

Each month, interest is added to every balance (APR divided by 12). Then every debt gets its minimum payment, and all remaining money, your extra payment plus the minimums freed up by debts you've already paid off, goes to one priority debt. When that debt is gone, the whole amount moves to the next one. This "rolling" effect is why paying extra shortens your timeline so much.

The "minimums only" comparison assumes you pay just the required minimum on each debt and never roll freed-up payments forward.

Snowball vs avalanche

Avalanche targets the debt with the highest interest rate first. It usually costs the least in total interest, which makes it the best choice if you want the cheapest path out of debt.

Snowball targets the smallest balance first. You may pay slightly more interest, but small debts disappear quickly, and many people find those early wins make it easier to stay on track. The best method is the one you will actually stick with.

Tips for paying off debt faster

Even $50 to $100 extra per month can cut months or years from a payoff plan. Put windfalls like tax refunds and bonuses toward the priority debt. Ask your card issuer about a lower APR, or consider a balance transfer or consolidation loan if the fees and rate make sense. Avoid adding new charges while you pay down balances.

Frequently asked questions

What if my minimum payment is lower than the monthly interest?

Then the balance grows and the debt can't be paid off at that payment. The calculator will warn you. Increase the payment or the extra amount until the balance starts to fall.

Does this work for student loans and car loans?

Yes. Any fixed-APR debt works: credit cards, personal loans, student loans, car loans. Mortgages also work if you want to see them alongside other debts.

Are the results exact?

No. Real lenders compute interest by daily balance and billing cycles, and variable rates change. Treat the results as a planning estimate.

Is my data saved?

No. Everything is calculated in your browser and nothing is sent anywhere.
