Highest APR first — minimizes total interest paid.

How This Calculator Works

Each month, interest is added to each card's balance using the formula:

Interest = Balance × (APR / 100 / 12)

Your monthly budget is first used to cover all minimum payments. Any remaining money is directed to the priority card — determined by your chosen strategy.

Avalanche: Extra payments attack the card with the highest APR first. Mathematically optimal — saves the most money.

Snowball: Extra payments attack the card with the lowest balance first. Psychologically powerful — early wins keep you motivated.

Interest saved is calculated by comparing your plan against a minimum-payments-only scenario. Data sourced from Consumer Financial Protection Bureau (CFPB). Last verified: April 2025.
