Avalanche vs Snowball: Which Actually Works?

Say you've got three debts. A $2,000 credit card at 22% APR. A $5,000 personal loan at 12%. And a $9,000 car loan at 5%. You've got $200 a month of extra cash after minimums. Where do you point it?

The internet has two answers. And they've been fighting about it for years.

Avalanche: The Math Answer

Pay minimums on everything. Throw all extra money at the highest interest rate first. In this case, the credit card at 22%.

Once that's gone, roll everything into the personal loan at 12%. Then the car loan.

This saves you the most money over time because you're eliminating the most expensive debt first. The math is clean and the spreadsheet loves it.

Snowball: The Human Answer

Pay minimums on everything. Throw all extra money at the smallest balance first. In this case, also the credit card (you got lucky with this example).

But imagine the credit card was $8,000 and the personal loan was $1,500. Snowball would say: knock out the $1,500 loan first. Get that win. Cross it off. Then use the freed-up minimum payment plus your extra $200 to attack the next one.

This method costs a bit more in total interest. But you see progress faster. And for a lot of people, seeing progress is the difference between sticking with it and quietly going back to minimums on everything.

The Honest Answer

Whichever one you'll stick with.

I know that sounds like a non-answer. But the gap between avalanche and snowball in total interest paid is usually a few hundred dollars over the life of the debt. The gap between either method and paying minimums on everything is thousands.

If you've tried avalanche before and quit because it felt like nothing was happening, try snowball. If you're the kind of person who finds motivation in knowing you're being mathematically optimal, avalanche. Both are infinitely better than spreading extra payments across all your debts at once, which is what most people do by default.

The Non-Negotiable Part

Regardless of which method you pick, one rule doesn't change: always pay at least the minimum on every debt, every month. Then direct whatever's left to your target debt.

Missing a minimum to put more toward your target debt is not a strategy. It tanks your credit, triggers late fees, and can put you in a worse position than when you started.

And here's the thing most avalanche-vs-snowball articles skip: the method only matters once you're actually ready to attack debt. On the Leak Ladder, high-interest debt sits at Rung 4. Anything at or above 7% APR. That means you should already have a spending plan, a starter emergency fund, and your full employer match sorted before you start throwing extra money at debt.
