Snowball vs Avalanche: Debt Payoff Strategy
TL;DR
Snowball pays the smallest balance first for early motivation; avalanche targets the highest interest rate to save the most money. Avalanche wins mathematically, but the strategy you'll actually stick with for years matters more than the one that's technically optimal.
If you have more than one debt, the order you pay them off in changes both how much interest you pay and how likely you are to finish. That's the whole debate between snowball and avalanche.
| Snowball | Avalanche | |
|---|---|---|
| Extra payments go toward | Smallest balance first | Highest interest rate first |
| Total interest paid | Usually higher | Usually lowest |
| Early motivation | Fast, visible wins | Slower first payoff |
The snowball method
Pay minimums on everything, then throw every extra dollar at your smallest balance first. Once it's gone, roll that payment into the next-smallest. The math isn't optimal, but the wins come fast - and a paid-off card or loan is a real, visible milestone that keeps you going.
The avalanche method
Same structure, different target: extra payments go to the debt with the highest interest rate first, regardless of balance size. This minimizes total interest paid over the life of your debt. Compare the two strategies side by side, and avalanche almost always wins on total dollars.
Which one wins?
Avalanche is faster and cheaper on paper - it saves real money in interest. But snowball has a track record of higher completion rates, because early wins are motivating and debt payoff is as much a behavior problem as a math problem. The "best" strategy is the one you'll actually stick with for the next 12-36 months.
- If your interest rates are close together, snowball's motivation edge probably outweighs the small math difference.
- If one debt has a dramatically higher rate (a credit card at 24% next to a car loan at 6%), avalanche's savings become too large to ignore.
- If you're not sure, run both and compare the actual numbers - projected payoff date and total interest - before committing.
That comparison is exactly what MoneyFlow's debt payoff planner does: enter your balances, payments, and interest rates, and see your snowball and avalanche payoff dates side by side instead of guessing which one wins.
