Debt payoff calculator: snowball vs avalanche
Updated November 5, 2026. Runs entirely in your browser; nothing you type is sent anywhere.
List each balance, APR, and minimum payment, then add what you can put toward debt after minimums. You'll see estimated payoff time and interest for snowball (smallest balance first) and avalanche (highest APR first), plus a calm sentence for money talks. Simple arithmetic only—not financial advice.
Add each debt (name, balance, APR, minimum payment). Extra monthly payment applies after minimums.
How to use the comparison
- Use statement balances and the APR you actually pay (including penalty rates if that is your situation).
- Minimums should match the current required payment, not a round guess.
- Re-run the numbers after a raise, a bonus, or when a bill negotiation frees monthly cash.
- Pick the method you will stick with. Avalanche often costs less interest; snowball often feels easier early. Consistency beats the perfect spreadsheet.
What to say when cash is tight
Knowing the payoff order is step one. Saying the next line on a bill, collections, rent, or family money call is where people freeze. The Bills Kit ($19) gives word-for-word lines for those moments plus Call Mode. If a raise or offer would change what you can put toward debt, see the Offer Kit ($29). One-time purchase, 14-day refund on both.

What is the debt snowball method?
Snowball pays the smallest balance first while you make minimums on the rest. Each time a balance hits zero, that payment rolls to the next-smallest balance. Many people like the early wins; interest cost can be higher than avalanche.
What is the debt avalanche method?
Avalanche pays the highest interest rate first while you make minimums on the rest. Mathematically it usually costs less interest over time if you stick with it. This tool is an estimate only.
Is this financial advice?
No. It is simple arithmetic on the balances, rates, and payments you type. It is not a loan offer, credit counseling, bankruptcy advice, or a substitute for advice from a qualified professional.
Guidance only, not legal, financial, or tax advice. The calculator does simple arithmetic on the numbers you enter.
