Debt Snowball Calculator
Pay off smallest balance first — payoff order with momentum-building wins.
Snowball method (smallest balance first)
47 months
Snowball gives faster psychological wins — first debt clears in months. Avalanche saves more money long-term.
The debt snowball is a payoff strategy that orders your debts from the smallest balance to the largest and attacks the smallest first, regardless of interest rate.
You keep paying the minimum on every debt, then put all of your extra money toward the smallest balance until it is gone, then roll that payment into the next one.
The appeal is momentum: eliminating a whole debt early gives you a visible win, which many people find easier to sustain than a purely math-driven plan.
How this calculator works
List every debt, make the minimum payment on all of them, then send every spare dollar to the debt with the smallest balance, ignoring interest rate. When that debt is gone, roll its entire payment (minimum plus extra) into the next-smallest balance. The total you pay each month stays flat, but the amount attacking each target grows as debts fall away, which is why it is called a snowball. The calculator tracks interest on each debt at its own APR and reports the order and dates that debts are cleared.
What affects the number
- Order is set by balance size, smallest to largest, not by interest rate.
- Keep paying every minimum; missing one can trigger fees and a penalty APR.
- Early payoffs come quickly, which builds motivation and improves the odds you finish.
- It usually costs somewhat more total interest than the avalanche, since high-rate debts may wait.
- The gap between snowball and avalanche is small when balances and rates are similar; it widens when a large balance carries a high APR.
- Windfalls like a tax refund or bonus accelerate the whole plan when applied to the current target.
Frequently asked questions
What is the debt snowball method?
You list your debts from smallest balance to largest, pay the minimum on all of them, and throw every extra dollar at the smallest. Once it is paid off, you roll that payment into the next-smallest debt. The quick early wins are meant to build momentum and keep you going.
Does the snowball or avalanche save more money?
The avalanche (highest APR first) almost always costs less in total interest because it kills your most expensive debt sooner. The snowball usually costs a little more but tends to have higher completion rates because early payoffs keep people motivated. If the numbers are close, the method you will actually stick with wins.
Should I stop paying minimums on my other debts?
No. The snowball only works if you keep every minimum payment current; missing one can trigger late fees, penalty APRs, and credit damage. Only the extra money beyond all the minimums goes to your smallest target.
How much more does the snowball cost than the avalanche?
It depends on the spread between your interest rates and where your biggest balances sit. When rates are similar the difference is often small; when a large balance carries a high APR that the snowball pays last, the gap grows. The calculator shows both totals so you can decide if the motivation is worth the cost.
