Debt Payoff

Debt Avalanche Calculator

Pay off your highest interest rate first to minimize total interest. Enter your debts and see your debt-free date.

Your Debts

Add each debt with its balance, APR, and minimum payment. Avalanche targets payoff by highest APR first to minimize total interest.

Extra Payment

How much extra can you pay each month (on top of minimums)?

$

Tip: putting extra money toward the highest APR usually saves the most interest.

How the Debt Avalanche Method Works

The Debt Avalanche method focuses on minimizing total interest by paying off the highest interest rate first.

  • List all debts by interest rate (highest → lowest)
  • Pay minimums on every debt
  • Apply all extra payment to the highest interest rate debt
  • When that debt is paid off, move to the next highest APR

This tool simulates interest month-by-month, so your payoff date and total interest reflect your inputs.

Why Avalanche Often Saves More Money

High-interest debt grows faster. By targeting the highest APR first, you reduce the most expensive interest early and typically pay less total interest than Snowball.

Pros and Cons

Pros
  • Usually minimizes total interest
  • Often fastest payoff when APRs vary widely
  • Mathematically optimal approach
Cons
  • May take longer to “feel” a win if small balances have low APR
  • Harder to stay motivated for some people

FAQ

Do I still pay minimums on everything?

Yes. Minimum payments are made on all debts. Your extra payment goes to the highest APR balance.

Does this include fees?

No. This calculator models balances, APR interest, and payments. Add fees into balances if you want to approximate them.
