Debt Payoff Calculator
Enter all your debts and compare the Avalanche (highest interest rate first) and Snowball (smallest balance first) payoff strategies side by side, right in your browser. See your debt-free date, a balance-over-time chart, your exact payoff order, and how much extra payments save you vs. minimums only. Nothing is sent to a server.
Multiple debts, one payoff plan
Add every debt with its balance, APR, and minimum payment, then add an extra monthly payment amount to accelerate payoff.
Avalanche vs. Snowball
Compare both strategies side by side — Avalanche targets the highest interest rate first to minimize total interest paid; Snowball targets the smallest balance first for faster individual wins.
Rolling minimum payments
As each debt is paid off, its minimum payment automatically rolls into your extra payment pool, accelerating the payoff of your remaining debts — just like a real payoff plan.
Your debt-free date and balance chart
See the actual calendar month you'll be debt-free, plus a chart of your total balance declining over time under your selected strategy — not just a number of months, but a visual sense of the whole payoff journey.
Payoff order timeline
See exactly which debt gets paid off first, second, and so on, and the calendar month each one is fully cleared — so you know exactly when each milestone arrives, not just the final debt-free date.
Extra-payment savings, quantified
See exactly how much interest and time your extra monthly payment saves you compared to paying only the minimums on every debt — a concrete number that makes the payoff plan's value clear.
Common Mistakes to Avoid
Only paying minimums on every debt
Solution:
Paying only minimums can take years longer and cost far more in interest — even a small extra monthly payment makes a large difference.
Picking Snowball for the lowest total interest
Solution:
Avalanche (highest APR first) minimizes total interest paid; Snowball is better for motivation from quick wins, but usually costs somewhat more in interest.
Frequently Asked Questions
Avalanche pays off the highest-interest debt first to save the most money overall. Snowball pays off the smallest balance first for quick psychological wins, even if it costs slightly more in interest.
Yes — interest accrues monthly on every debt with a remaining balance, exactly as it would with real creditors.
