Debt payoff calculator
Compare the snowball and avalanche methods with your balances, interest rates and monthly payments.
Estimate only. Fixed rates, monthly interest, no fees or new borrowing. All amounts in one selected currency; changing the currency label does not convert the numbers.

FAQ
Does the calculator send my debts to a server?
Calculations run in your browser. Calculator inputs are not sent to analytics. Older shared-plan links contain the plan’s numbers and debt names in the URL; anyone with that link can read them.
Are payoff dates guaranteed?
No. Estimates assume fixed annual rates, monthly interest and payments made as planned. Fees, daily interest, changing rates and lender-specific rules are not included.
Can I import a web plan into the app?
Not currently. The App Store link opens the app listing; it does not transfer your balances or schedule. Enter your debts in the app to track them.
