Debt Payoff Tips

  • Avalanche usually saves the most money by attacking the highest-rate debt first.
  • Snowball can be easier to stick with if early balance wins keep you motivated.
  • Balance transfers may reduce interest, but fees and promo expiry dates matter.
  • Lump sums from refunds or bonuses can accelerate the plan materially.
  • Do not ignore minimums on non-priority debts while targeting the current focus balance.

What this calculator does

Build a debt-free timeline from your real balances

The calculator combines each debt balance, interest rate, minimum payment, and extra monthly payment. It estimates how long repayment may take, how much interest could be paid, and which debt is targeted first under avalanche or snowball ordering.

How to use it

Enter every debt, then choose your payoff style

Add credit cards, loans, or lines of credit with their current balances and minimum payments. Then test how an extra monthly payment changes the payoff date, and compare the avalanche method with the snowball method before choosing a plan you can maintain.

Inputs explained

What each debt input changes

Balance

The amount currently owing on the debt. Use the latest statement balance if possible.

Interest rate

The annual rate used to estimate monthly interest. Credit cards usually have the highest rates.

Minimum payment

The amount still paid to every debt before extra money is applied to the priority balance.

Extra monthly payment

Additional cash directed to the current focus debt after all minimum payments are covered.

Example calculation

Example: three debts and $200 extra per month

With the starter example, the calculator models $25,000 of debt, $470 in minimum payments, and $200 of extra monthly cash. The selected method estimates a payoff timeline of 4yr 2mo and total interest of $4,551.

How to read your result

Use the interest and timeline together

A lower-interest plan is useful only if you can stick with the payment. Compare the payoff month, total interest, and priority order, then use the net pay calculator or savings goal calculator to make sure the payment fits your monthly cash flow.

Common mistakes

Debt payoff estimates depend on payment discipline

  • - Forgetting to keep making minimum payments on every non-priority debt.
  • - Using a promotional balance-transfer rate after the promotion has expired.
  • - Adding new purchases to a credit card while modeling it as a shrinking balance.
  • - Comparing avalanche and snowball without checking which one you will actually follow.

Methodology and assumptions

Last updated: April 2, 2026

This calculator applies monthly interest to each debt, makes the required minimum payments, and then applies any extra payment to the current priority debt under either avalanche or snowball ordering.

Assumptions

  • Interest is modeled monthly using a simple annual-rate-to-monthly-rate conversion.
  • Minimum payments are assumed to remain constant rather than changing with lender formulas.
  • The avalanche method prioritizes the highest rate first; the snowball method prioritizes the smallest balance first.
  • This tool does not model fees, changing rates, missed payments, or promotional financing expiries.
