If you're trying to pay off multiple debts, two strategies dominate the personal finance world: the debt avalanche and the debt snowball. Both work. They just work differently — and the best one for you depends as much on your psychology as it does on the math.
Here's a clear breakdown of both methods, a real comparison with numbers, and a framework for choosing the right one.
Pay the minimum on all your debts. Put every extra dollar toward the debt with the highest interest rate first. Once that's paid off, roll that payment into the next highest rate debt.
Best for: People who are motivated by saving money and want the mathematically optimal solution.
Pay the minimum on all your debts. Put every extra dollar toward the debt with the smallest balance first. Once that's paid off, roll that payment into the next smallest balance.
Best for: People who need motivational wins to stay on track. Popularized by Dave Ramsey.
Let's say you have these four debts and $500/month to put toward debt payoff:
| Debt | Balance | Interest Rate | Min Payment |
|---|---|---|---|
| Credit Card A | $3,200 | 24.99% | $64 |
| Credit Card B | $1,100 | 19.99% | $22 |
| Personal Loan | $8,500 | 12.5% | $170 |
| Car Loan | $5,800 | 6.9% | $116 |
Total minimum payments: $372/month. Extra available: $128/month.
| Metric | Result |
|---|---|
| Total interest paid | $4,218 |
| Time to debt-free | 38 months |
| First debt eliminated | Month 19 (CC-A) |
| Metric | Result |
|---|---|
| Total interest paid | $4,891 |
| Time to debt-free | 40 months |
| First debt eliminated | Month 6 (CC-B) |
Avalanche wins on math: Saves $673 in interest and finishes 2 months faster. But the snowball gives you your first win in month 6 vs month 19 — that's 13 months of extra motivation.
Research from the Harvard Business Review found that people using the snowball method were more likely to successfully eliminate all their debt — because the early wins kept them engaged. The avalanche method is mathematically superior, but only if you stick with it.
The best debt payoff method is the one you'll actually follow through on. A $673 savings means nothing if you abandon the plan at month 8.
Some people start with the snowball to get an early win, then switch to the avalanche once they've built momentum. If you have one small debt that can be eliminated in 1-2 months, paying it off first and then switching to highest-rate-first is a perfectly reasonable strategy.
Enter your balance, interest rate, and monthly payment to see exactly when you'll be debt-free — and how much you'll save with extra payments.

Pick the one you'll stick with, eliminate new debt, and keep a small emergency fund in place. The specific method matters far less than the consistency of execution.
