Questions
What's the difference between debt snowball and avalanche?
Avalanche pays extra toward the debt with the highest interest rate first, which usually costs the least. Snowball pays the smallest balance first, so you clear whole debts sooner. Both keep your total monthly payment the same and roll freed-up payments into the next debt.
Which method should I use?
Avalanche usually saves more interest. Snowball can feel more motivating. This calculator shows both so you can see how big the difference is for your debts.
Why does 'Minimums only' take so long?
When you pay only the minimums, much of each payment goes to interest. Adding even a small extra amount, and rolling payments forward as debts are paid off, can save years.
