About this tool

Interest accrues monthly, minimums go out on everything, and your extra payment targets one debt at a time — smallest balance (snowball) or highest rate (avalanche). Once a debt clears, its minimum joins the extra-payment pool for the next target — the "snowball" effect.

Snowball vs avalanche

Avalanche saves the most money mathematically. Snowball usually costs a bit more but clears small debts fastest, which helps many people stick with the plan. Neither is certified financial advice — a planning estimate only.
