Debt Avalanche vs. Snowball: Which Pays Off Debt Faster?
The avalanche saves the most interest; the snowball delivers faster wins. Here is how each method works, the real cost difference, and how to pick.
When you are paying off multiple debts, two strategies dominate the advice: the avalanche and the snowball. Both have you pay minimums on everything and throw every extra dollar at one target debt — they just disagree on which debt.
The avalanche (lowest interest)
Attack the debt with the highest interest rate first, regardless of balance. When it is gone, roll its payment into the next-highest rate, and so on.
- Pro: mathematically optimal — pays the least total interest and is usually fastest.
- Con: if your highest-rate debt is also large, the first win can feel far away.
The snowball (fastest wins)
Attack the smallest balance first, regardless of rate. Clear it, then roll that payment into the next-smallest.
- Pro: quick early wins build momentum and motivation.
- Con: you may pay somewhat more interest overall.
How big is the difference?
Usually smaller than people expect — often tens to a few hundred dollars for typical consumer debt, though it grows with large, high-rate balances. The avalanche wins on paper; the snowball wins on psychology.
How to choose
- Motivated by numbers? Avalanche.
- Motivated by momentum? Snowball.
- The best method is the one you will actually stick with. A plan you follow beats an optimal plan you abandon.
The single biggest lever is not which order you pick — it is the you add on top of the minimums. See how a few hundred dollars a month changes your payoff date with the free , which compares both methods side by side.
