Debt Payoff Calculator
Add your debts, choose snowball or avalanche, and see exactly when you'll be debt-free — and how much interest each method saves.
Payoff order: Credit card → Personal loan → Car loan
| Year | Avalanche | Snowball |
|---|---|---|
| 2026 | $22,000 | $22,000 |
| 2027 | $13,319 | $13,530 |
| 2028 | $3,326 | $3,776 |
| 2029 | $0 | $0 |
On $22,000 of debt across three balances — a $6,000 card at 22.9%, a $12,000 car loan at 6.5% and a $4,000 personal loan at 11% — paying the minimums plus $300 a month clears it in 28 months with $2,730 of interest using the avalanche method (highest rate first).
The snowball method (smallest balance first) takes 29 months and costs $3,191 — $461 more in interest. Avalanche is always cheaper on paper; snowball wins when clearing a whole debt early is what keeps you going.
Snowball vs. avalanche
Both methods pay the minimum on every debt, then throw every spare dollar at one target. The avalanche targets your highest interest rate first — mathematically the cheapest and fastest. The snowball targets your smallest balance first, clearing whole debts quickly for motivation.
As each debt is cleared, its payment rolls over onto the next — the snowball effect that accelerates payoff no matter which order you choose. The chart compares your total balance falling under each method.

How we calculate this
Month-by-month simulation: interest accrues, minimums are paid, and the remaining budget targets one debt by the chosen strategy. Estimates only — not financial advice.
Estimates assume fixed rates and consistent payments. Actual interest and payoff depend on your lenders' terms and your payment history. Not financial advice.
