Debt Payoff Calculator — free online

When you owe money on a few cards or loans, it's hard to know which one to pay off first, or how long the whole thing will take. You just want a clear plan. We added a free tool that does it — Debt Payoff Calculator — right in your browser.

What it does

It compares two ways of paying down debt: the snowball (smallest balance first) and the avalanche (highest interest first). You enter your debts and how much extra you can put toward them, and it shows the months until you're debt-free, the total interest you'd pay, and the order to tackle them in. You can see both methods side by side and pick the one that fits you.

Nothing leaves your device

The whole thing runs in your browser. Your balances and numbers are never uploaded and nothing is saved anywhere. When you close the tab, it's gone.

How to use it

  1. Open Debt Payoff Calculator and add each debt: balance, interest rate, and minimum payment.
  2. Type the extra amount you can pay each month.
  3. Read the snowball vs avalanche results and follow the payoff order that works for you.

It's free with no limit. There are more small tools on the Apps page.
