If you're juggling several debts, two strategies dominate. The avalanche method attacks the highest interest rate first, which saves the most money mathematically. The snowball method clears the smallest balance first, which delivers a quick psychological win and momentum. The avalanche is cheaper; the snowball is stickier. For most people, the method they'll actually finish beats the one that's optimal on paper.
This calculator models a single balance, but the lesson scales: every extra dollar above the minimum goes straight at the principal, and on a high-APR card that's one of the best guaranteed "returns" you can get. Need a structured plan? See our guide to paying off debt fast.
