The two methods in one line
Both methods say: pay the minimum on every debt, then throw all your spare money at one target debt until it is gone, then roll that money to the next. They differ only in which debt you target first.
- Avalanche — target the debt with the highest interest rate first.
- Snowball — target the debt with the smallest balance first.
Avalanche: the cheapest path
Paying the highest-rate debt first removes your most expensive interest as quickly as possible, so the avalanche method always costs the least total interest and is usually the fastest to full payoff in pure math terms. The downside is psychological: if your highest-rate debt also has a large balance, it can take a long time to see a single account disappear.
Snowball: the motivating path
Paying the smallest balance first means you clear an entire account quickly, which delivers an early win and frees up that minimum payment to add to the next debt. The trade-off is that you may pay a little more interest overall if a small debt has a low rate while a large debt sits at a high rate.
| Card A | 1,500 @ 24% |
| Card B | 6,000 @ 19% |
| Loan C | 3,000 @ 9% |
| Avalanche order | A → B → C (least interest) |
| Snowball order | A → C → B (fastest first win) |
Which is actually faster and cheaper?
Avalanche wins on math: less interest and, usually, a slightly earlier finish. Snowball wins on behavior: studies of real borrowers find people are more likely to stick with a payoff plan when they get early wins. The best method is the one you will actually follow to the end.
How to choose
- Motivated by numbers and want to pay the least? Use avalanche.
- Need momentum and quick wins to stay on track? Use snowball.
- Want a blend? Knock out one tiny balance first for the win, then switch to highest-rate order.
Before you start
List every debt with its balance, rate and minimum payment, then decide how much extra you can put toward the target each month. If several balances carry very high rates, also compare a consolidation loan, which can lower the rate you are fighting in the first place.
The honest answer most calculators won't give you: the math says avalanche, but the method that actually clears your debt is the one you don't quit. If watching a balance hit zero keeps you going, the “suboptimal” snowball can beat a perfect plan you abandon in month three.
Frequently asked questions
Which method saves the most money?
The avalanche method, because paying the highest interest rate first removes your most expensive debt soonest and minimizes total interest paid.
Which method is faster?
Avalanche is usually slightly faster to full payoff in pure math. Snowball can feel faster because you clear individual accounts sooner, which helps many people stay motivated.
Can the snowball ever beat the avalanche?
On total interest, rarely. But if the snowball keeps you committed and the avalanche would cause you to give up, the snowball can produce the better real-world outcome.
Should I consolidate instead?
If several debts carry high rates, a lower-rate consolidation loan can reduce interest before you even apply a payoff method. Compare the all-in cost first.
The example just orders the same debts two ways and applies the same extra payment; real payoff time and interest depend on your exact balances, rates and minimums.
