About the Debt Avalanche Calculator

List each debt with its balance, APR and minimum payment, and enter your total monthly budget for debt. The calculator plans the avalanche order, highest rate first, and shows when you'll be debt-free and the interest you'll pay.

With the debt avalanche you pay minimums on everything and send every spare amount to the highest-interest debt. It always costs the least interest; the trade-off is that the first debt may take longer to clear.

The formula

Each month: interest added, minimums paid, extra to the priority debt; freed payments roll over

Worked example

The four example debts on this page, 20,600 in total, with 800 a month

Minimums first, then everything extra to the 29.99% store card, then the 24.99% card
Debt-free in 2 years 6 months
Total interest: about 3,219
