Debt Payoff Calculator

Compare avalanche vs snowball, see payoff timelines, and how extra payments save interest.

Two strategies

Avalanche — Put extra money toward the debt with the highest interest rate first. You pay less total interest. Snowball — Put extra toward the smallest balance first so you knock out accounts sooner and build momentum. Both work; choose what keeps you motivated.
