Debt Avalanche Method

Picture this: you've got a credit card at 24%, a car loan at 6%, and a student loan at 4%. The debt avalanche says to throw every spare dollar at that 24% card first—because that's where interest is eating you alive—while making minimum payments on everything else.

Once the highest-rate debt is gone, you move to the next highest. It's the mathematically optimal order because you're always attacking the debt that's costing you the most per dollar owed.

How much you save compared to other methods (like the snowball) depends on the gap between your interest rates and the size of each balance. If your priciest debt also has the biggest balance, the avalanche could save you thousands. If the highest-rate debt is tiny, the savings difference shrinks.

The catch? Psychology. If your highest-rate debt is also your largest, it could take months—or years—to knock it out, with no quick wins along the way. That long slog is where a lot of people lose steam and quit.

Here's a practical move: run the numbers for both the avalanche and the snowball method. If the snowball only costs you $200 more in interest over the full payoff timeline, those motivational quick wins might be worth the price. But if the gap is $2,000+, the avalanche's math advantage gets hard to walk away from.
