Let’s be straight: carrying several balances is exhausting, and you deserve a clear plan. Two strategies dominate the conversation, and they optimize for two different things — math, and momentum. Both work. The trick is picking the one you’ll see through to zero.
The two methods, side by side
With either one, you pay the minimum on everything, then throw every spare dollar at a single target debt:
| Avalanche | Snowball | |
|---|---|---|
| Target order | Highest interest rate first | Smallest balance first |
| Optimizes for | Least interest paid | Fastest first win |
| First payoff | Slower | Sooner |
| Best if you’re driven by | The numbers | Visible progress |
The avalanche method (lowest cost)
List your debts by interest rate, highest first. Pay the minimum on everything, then attack the highest-rate debt. When it’s gone, roll that payment into the next one down. Because you always kill the most expensive money first, the avalanche mathematically minimizes total interest and usually clears everything soonest.
The snowball method (most momentum)
List your debts by balance, smallest first. Pay the minimums, then attack the smallest balance regardless of rate. Knock it out, feel the win, and roll its payment into the next-smallest. You’ll pay slightly more interest than the avalanche — but you’ll notch your first “paid in full” far sooner.
The best debt strategy is the one you’ll actually finish. A plan that keeps you motivated beats a mathematically perfect plan you abandon.
A worked example
Say you owe a $500 store card at 18% and a $4,000 card at 24%, with $300/mo to put toward debt:
- Avalanche hits the $4,000 card (24%) first — you pay less total interest, but your first payoff takes several months.
- Snowball clears the $500 card in about two months — a fast, motivating win — then rolls into the big one.
The interest difference here is small; the psychological difference is large. That’s the whole trade-off.
How to choose
- Comfortable with numbers and disciplined by nature? Avalanche.
- Need encouragement and quick wins to stay the course? Snowball.
- Several high-rate debts that consolidation could simplify? Compare a single lower-rate loan first.
