Debt payoff · snowball · Excel
Debt snowball calculator — compare payoff methods month by month
Short answer. Enter balances, APRs, minimums, and a monthly extra. Snowball: direct the extra to the smallest balance while paying every other minimum (CFPB).
- Update the plan from your latest statementstype the date
Check your own case.

Your debt plan
Compare snowball and avalanche with your numbers
Try three debts here, then use the Excel workbook for up to ten. The schedule estimates months, interest, and remaining balance without promising a payoff date.
- Copy each balance, APR, and minimum from the latest statement.
- Pay every required minimum, direct the extra by your chosen method, and avoid new charges.
- If minimums are unaffordable, contact creditors early and use trustworthy help; avoid debt-relief guarantees.
Educational estimate, not advice or a payoff promise. Variable rates, fees, rounding, late payments, and new charges change the result.

Deadlines
The rules, with the source
| What | Deadline | Source |
|---|---|---|
| Snowball | direct the extra to the smallest balance while paying every other minimum | CFPB |
| Avalanche | direct the extra to the highest APR while paying every other minimum | CFPB |
| Monthly interest | previous balance times annual percentage rate divided by twelve | estimate |
| Payment budget | required minimums plus the extra amount available each month | user input |
| Estimated payoff month | the first calculated month with no balance inside the schedule horizon | estimate |
Neither method is best for everyone. Avalanche often reduces interest; snowball may make progress easier to sustain. Variable rates, fees, rounding, late payments, and new charges change the result.
