How the debt snowball actually works

The snowball method is less about math and more about momentum — and momentum is what actually gets debt paid off.

Here's the whole idea in four steps. First, list every debt you have from the smallest balance to the largest, ignoring interest rates for now. Second, pay the minimum payment on every debt so nothing falls behind. Third, throw every extra naira, dollar, or pound you can find at the smallest debt until it's gone. Fourth — and this is the part that makes it a snowball — once that smallest debt is paid off, you roll its entire payment onto the next-smallest debt.

That rolled-over amount keeps growing. By the time you reach your biggest debt, you're hitting it with a payment far larger than you could have managed at the start. Each debt you clear is a visible win, and those wins are what keep people going long enough to actually finish. Studies of real borrowers have found that people who attack the smallest balance first are more likely to eliminate their debt entirely — not because it's mathematically optimal, but because they don't quit.

Why not just target the highest interest rate?

You can — that's the avalanche method, and on paper it saves you more money. But "on paper" assumes you never lose motivation, never get discouraged by a huge balance that barely moves, and never give up. For most people, the snowball's early wins are worth more than the interest they'd save. The tool above lets you compare both instantly, so you can see the real difference for your numbers and decide.
