Debt Avalanche vs. Snowball: Which Actually Gets You Out Faster

Both methods have you pay minimums on every debt and throw every extra dollar at one target debt, then roll that payment into the next once it's gone. They only differ in which debt you target first.

Avalanche: highest interest rate first

You attack the debt with the highest interest rate, regardless of balance. Mathematically, this is always the cheapest path — you pay the least total interest and get out of debt in the least time, because you're cutting off the rate that's costing you the most every month it exists.

Snowball: smallest balance first

You attack the smallest balance, regardless of rate. This is mathematically worse — you'll typically pay somewhat more in total interest than the avalanche method — but it produces a paid-off account faster, which is the entire point: it's a method built around behavior, not math.

Why the "worse" math sometimes wins

Debt payoff is a multi-year effort for most people, and the methods that work are the ones you actually stick with. If watching a balance hit zero is what keeps you making extra payments instead of giving up after month four, the snowball's small behavioral edge can outweigh its larger mathematical disadvantage. The avalanche method saves more money only if you follow through on it for the whole payoff period.

The best method is the one you'll still be using in month eighteen, not the one that wins on a spreadsheet in month one.

A middle path

Some people target the highest-rate debt first, but if two debts are close in rate, break the tie by paying off the smaller one first — capturing most of the avalanche's savings while still getting an early "win." This isn't a third named method, just a reasonable hybrid: when the math is close, let behavior decide.

One thing that matters more than either method

How much extra you're able to put toward debt each month affects your payoff timeline far more than which debt you target first. Before optimizing the order, it's usually worth checking whether spending can be trimmed elsewhere to increase the extra payment amount — that lever is typically bigger than the avalanche-vs-snowball choice itself.
