Debt Payoff Optimizer

Free · No sign-up to use

The smartest, fastest way out of debt.

There are two proven ways to clear debt: the snowball (smallest balance first, for motivation) and the avalanche (highest rate first, for the least interest). This optimizer runs both on your real numbers and tells you which gets you free cheapest and fastest.

How it works

The snowball, in four steps

  1. List every debt — balance, interest rate and minimum payment.
  2. Pay minimums on all of them, so nothing falls behind.
  3. Attack the smallest balance with every spare dollar until it’s gone.
  4. Roll that whole payment onto the next-smallest — the snowball grows, and it speeds up.

Snowball or avalanche?

The avalanche (highest interest rate first) saves slightly more money on paper. The snowball (smallest balance first) usually wins in real life, because the quick early wins keep you going. This calculator uses the snowball — and still shows you the interest you save. The best method is the one you actually finish.

Questions

Common questions

Is this calculator free?

Yes — completely free, and you don’t need to sign up to use it. Everything runs in your browser; your numbers never leave your device unless you choose to email yourself the plan.

Snowball vs avalanche — which is better?

Avalanche saves marginally more interest; snowball keeps you motivated with fast early wins and has a much higher finish rate. We use the snowball and still show your interest saved.

What is the “extra” payment?

Any amount above your minimums that you can put toward debt each month. Even $50 extra can cut months — try changing it and watch the date move.

Are my numbers private?

Completely. The calculation happens entirely in your browser. We never see your balances.
