How the methods work
Snowball: List debts smallest balance to largest. Pay the minimum on everything, then throw every spare pound at debt #1. When it's gone, roll that payment into debt #2. Psychologically powerful — you see debts disappearing quickly.
Avalanche: Same idea, but ordered by interest rate (highest first). Mathematically optimal — you always pay less total interest. Best if you're disciplined enough to stick with it even when progress feels slow.
