Debt Payoff Calculator
List your debts, add any extra you can pay each month, and see both payoff plans side by side — snowball (smallest balance first, fastest wins) vs avalanche (highest rate first, least interest). Everything runs in your browser; nothing you type leaves your device.
Your debts
On top of all the minimums. When a debt is paid off, its old payment rolls into the next one automatically — your total monthly payment never drops.

Common questions
What's the difference between snowball and avalanche?
Snowball pays your smallest balance first, so a debt disappears sooner — the wins keep people going. Avalanche pays your highest APR first, which costs the least total interest. This calculator runs both on your real numbers so the trade-off is in dollars and months, not slogans.
Why does my monthly payment stay the same when a debt is paid off?
That's the point of both methods: the freed payment rolls into the next debt instead of disappearing into spending. Your outlay stays flat; each remaining debt just dies faster. The calculator models the roll-over automatically.
What if it says my debts never get paid off?
Your minimums plus extra don't cover the monthly interest, so balances grow. Try raising the extra payment a little and watch the plan flip — or talk to a nonprofit credit counselor about options beyond this calculator.
Is this financial advice?
No. It's an arithmetic tool on the numbers you type, assuming fixed APRs and on-time minimums. It ignores fees, rate changes, and new charges.
Does my data leave my device?
No. Every calculation happens in your browser. Nothing you type is sent anywhere, and this page makes no external calls.
