What is the debt avalanche method?

The debt avalanche method prioritizes paying off debts with the highest interest rate first, while paying minimums on all other debts. This minimizes total interest paid and is mathematically optimal. After the highest-rate debt is cleared, you 'roll' those payments to the next highest-rate debt.

What is the debt snowball method?

The debt snowball method pays off the smallest balance first, regardless of interest rate, while paying minimums on all others. This provides psychological wins through quick debt eliminations. Research shows some people stay more motivated with this method, even though it typically costs more in total interest than the avalanche.
