If you have more than one debt to pay off, you’ll eventually run into two competing strategies: the debt snowball and the debt avalanche. Both work. The “right” one depends less on math and more on which one you’ll actually stick with.
The debt snowball
List your debts from smallest balance to largest, ignoring interest rates. Pay minimums on everything except the smallest debt, and throw every extra dollar at that one until it’s gone. Then roll that entire payment into the next-smallest debt, and repeat.
The appeal is momentum: you get a win early, often within a few months, and that psychological boost tends to keep people motivated through the rest of the payoff process.
The debt avalanche
List your debts from highest interest rate to lowest, regardless of balance. Pay minimums on everything except the highest-interest debt, and throw every extra dollar there first. Once it’s paid off, move to the next-highest rate.
Mathematically, this method saves you more money in total interest, because you’re eliminating your most expensive debt first. It just requires more patience — if your highest-interest debt also happens to be your largest balance, the first “win” can take a while to arrive.
Which one actually works better
On paper, the avalanche always wins — you pay less interest overall. But debt payoff isn’t purely a math problem; it’s also a behavior problem. If you’ve tried and abandoned a payoff plan before, the snowball’s early wins might be what actually keeps you going long enough to finish. If you’re motivated by minimizing the true cost and don’t need the emotional wins to stay consistent, the avalanche will save you real money.
A middle-ground option
Some people use a hybrid: start with the snowball to build momentum on one or two small debts, then switch to the avalanche once you have some quick wins behind you. There’s no rule that says you have to pick one method and follow it rigidly — the only method that fails is the one you stop using.
The bottom line
The avalanche saves more money. The snowball is easier to stick with for most people. The best method is the one you’ll actually follow through on for the next 12–24 months, not the one that wins in a spreadsheet.
