The calculator keeps the total monthly debt budget constant and rolls freed minimum payments into the next targeted balance.

Snowball and avalanche use different priorities

The snowball method targets the smallest balance first, which may create earlier account-level wins. The avalanche method targets the highest APR first, which generally reduces interest when all other assumptions are equal.

How the comparison is calculated

Both strategies use the sum of your entered minimum payments plus the extra payment. Interest is estimated monthly. When one balance reaches zero, its payment is redirected to the next targeted debt.

Compare debt snowball and avalanche with the same monthly budget

The snowball method directs extra money to the smallest balance, while the avalanche method directs it to the highest APR. Both continue minimum payments on every other debt. The comparison should use the same debts and total monthly budget so the effect of ordering is isolated.

How to use this page

Each month, interest is applied and required payments are made. Remaining budget is directed to the active target. When one debt is repaid, its payment rolls into the next target. The estimate compares time and interest across the two ordering rules.

Practical exampleA small low-rate balance may disappear earlier under snowball, creating a quick milestone. Avalanche may save more interest when a larger high-rate balance would otherwise remain outstanding longer.

Inputs to verify

Enter current balances, APRs and minimums from recent statements.
Do not count a payment twice when setting the total debt budget.
Keep an emergency buffer so an unexpected expense does not create new card debt.

Common questions

Which strategy is mathematically cheapest?

Avalanche generally minimizes interest when payments and behavior remain identical.

Why would someone choose snowball?

Some borrowers value earlier account closures and motivation, even if estimated interest is higher.
