Debt Payoff Calculator
Plan how to clear several debts together — compare the snowball method (smallest balance first) with the avalanche method (highest rate first) and see which saves you more interest.

How to use
- Enter up to three debts — balance, rate and minimum payment (keep the balance 0 for any debt you do not have).
- Enter the extra amount you can pay each month on top of the minimums.
- Compare the months and total interest for both methods.
- Whichever method you choose, roll the minimum payment of each cleared debt into the next debt — that is the core idea of snowball and avalanche.
Note
The simulation applies interest each month first, then minimum payments, then the extra amount on the target debt. When a debt is cleared, its minimum payment joins the extra amount.
Tips
- Avalanche usually wins on interest; snowball wins on motivation — pick the one you will stick with.
- Even a small extra monthly amount shortens the payoff a lot — enter what you can truly afford.
- This is an estimate only — real interest, fees and late payments can change the numbers.
