Debt Payoff Calculator
Plan a debt payoff strategy with multiple debts. Choose snowball or avalanche, set your monthly budget, and export a yearly snapshot.
Strategy notes
Avalanche prioritizes highest APR first to reduce interest. Snowball prioritizes smallest balance first to build momentum.
Estimated payoff
3y 3m
Total interest: $4,574
Monthly budget
$800.00
Extra: $155.00
Tip
If your budget is less than the sum of minimums, increase it or adjust minimum payments to avoid negative amortization.
| Year | Balance | Total interest |
|---|---|---|
| 1 | $18,877 | $2,577 |
| 2 | $10,772 | $4,072 |
| 3 | $1,659 | $4,559 |
Export the yearly snapshot as CSV.
Our debt payoff calculator helps you build a simple payoff plan using a single monthly budget. Try both strategies to understand the trade-offs between motivation (snowball) and interest savings (avalanche).

Frequently Asked Questions
What is the debt snowball method?
Snowball pays minimums on all debts and puts extra money toward the smallest balance first. As debts are paid off, you roll freed payments into the next debt.
What is the debt avalanche method?
Avalanche pays minimums on all debts and puts extra money toward the highest interest rate (APR) first, usually minimizing total interest.
Why is my payoff time very long?
If your budget is close to the sum of minimum payments, payoff can be slow. Increasing budget or lowering rates (e.g., refinancing) can help.
Does this include fees or new purchases?
No. It assumes a fixed APR and fixed monthly budget with no new borrowing. Add buffer in your budget if needed.
