There are two proven ways to get out of debt. One wins with math; the other, with psychology. The best is, almost always, the one you'll actually finish.
The starting point
List all your debts: how much you owe, the minimum payment and the interest rate of each. The strategy is the same in both methods: you keep paying the minimum on all of them and attack just one with every extra dollar you can. The question is which one first.
Snowball method
You attack the smallest debt first, regardless of interest. When you pay it off, that payment rolls into the next debt, and the "snowball" grows and moves faster.
Why it works: you win early. Each debt cleared is a victory that keeps you motivated. It's pure psychology, and that's why many people actually finish.
Avalanche method
You attack the debt with the highest interest rate first. Mathematically it's optimal: you pay less interest overall and get out sooner.
Why it's hard: if your most expensive debt is also the biggest, you can go months without a single victory and quit halfway.
Which do I choose?
The avalanche wins on the spreadsheet. The snowball wins in real life, because you finish it.
If the interest difference between your debts is small, go with the snowball and enjoy the quick wins. If you have a debt with a monstrous rate — a card at 70-90% — the avalanche will save you real money: start there.
