Debt Payoff Calculator
A debt payoff calculator turns scattered minimums into one calendar you can print. This worked example uses two credit cards and a car loan with a $500 monthly pool. Avalanche sends every extra dollar to the highest APR first; snowball clears the smallest balance for a faster psychological win. Both methods roll freed minimums forward, which is why either beats paying minimums alone.
The comparison strip at the top is the main output: debt-free month, total interest, and which account disappears first under each method. Controls below accept up to twelve debts with custom labels. Download PDF or CSV for the strategy you pick. Numbers never upload.
Planning estimate only, not financial advice. No fees, promo APR windows, or collections modeling.
Your debts stay in your browser. We never see them, and nothing is saved.
