There are two standard ways to order debt payoff, and personal finance content usually presents them as a math question. It's really a behavior question.
The two methods
Avalanche: pay off the highest-interest-rate debt first, minimums on the rest. This saves the most money in total interest paid — it is the mathematically optimal order.
Snowball: pay off the smallest balance first, regardless of interest rate, minimums on the rest. This is not mathematically optimal, but it produces a real, visible win faster — one debt fully gone — which is what keeps most people going.
Why the "wrong" answer often wins in practice
The avalanche method is provably better on paper, but only if you stick with it for the full payoff period, which can be years. The snowball method's early wins are a real behavioral mechanism, not a gimmick — momentum from finishing something is often what determines whether the plan survives month six, not the interest math from month one.
A simple way to decide
If you're confident that seeing the total-interest math motivates you more than a quick win does, use avalanche. If you've started and abandoned a debt payoff plan before, the snowball method's early completions are worth more than the extra interest they cost.
