Debt Avalanche vs Debt Snowball: Which Pays Off Debt Faster?
We ran the numbers on the debt avalanche and debt snowball methods with the same budget. See how much each one saves, when the first debt disappears, and how to pick.
If you have more than one debt, the question isn't only how much to pay. It is also which debt to pay first. The two most popular strategies, the debt avalanche and the debt snowball, answer that differently. We ran the same example through both so you can see the real trade-off.
How both methods work
Both methods start the same way:
- List every debt with its balance, interest rate (APR) and minimum payment.
- Decide on a fixed monthly amount for debt payments, more than the total of the minimums.
- Pay the minimum on every debt, and put all the extra money toward one target debt.
- When the target is paid off, roll its whole payment into the next target.
The only difference is the order of the targets:
- Avalanche: target the highest interest rate first.
- Snowball: target the smallest balance first.
The example: same debts, same budget
Imagine someone with three debts and $700 per month to put toward them:
| Debt | Balance | APR | Minimum payment |
|---|---|---|---|
| Store card | $1,500 | 15% | $45 |
| Visa card | $7,000 | 25% | $175 |
| Car loan | $9,000 | 7% | $250 |
Minimums add up to $470, so $230 a month is extra. We simulated both plans month by month, with interest calculated monthly:
| Avalanche (highest rate first) | Snowball (smallest balance first) | |
|---|---|---|
| Order | Visa → Store card → Car | Store card → Visa → Car |
| First debt fully paid | Month 22 | Month 6 |
| Debt-free | Month 30 | Month 30 |
| Total interest paid | ≈ $3,110 | ≈ $3,355 |
Hypothetical example for illustration. Your results depend on your balances, rates and payment amount.
What the numbers tell us
- The avalanche saved about $245 in interest because the 25% card was attacked first.
- The snowball delivered a win 16 months sooner. The store card was gone by month 6, compared with month 22 for the first payoff under the avalanche.
- In this case both plans finished at the same time. With bigger gaps in interest rates or larger balances, the avalanche can finish sooner and save much more.
Which method should you choose?
Choose the avalanche if…
- You are motivated by numbers and can stay committed without quick wins.
- One of your debts has a much higher rate than the others, like a credit card at 25%+ next to a 5% loan.
- Your balances are large, so the interest difference adds up.
Choose the snowball if…
- You have tried to pay off debt before and lost steam.
- Your debts have similar interest rates, so the cost difference is small.
- You have several small balances you can knock out quickly. Fewer bills also means fewer chances to miss a payment.
The honest answer: the best method is the one you stick with. Mathematically the avalanche wins, but an abandoned plan costs far more than a few hundred dollars of interest.
Ways to speed up either plan
- Find more monthly cash. Even $100 extra a month can cut months off the timeline. The 50/30/20 budget can help you find it.
- Lower the rate. A 0% balance transfer card (watch the transfer fee, often 3–5%, and the date the promo ends) or a lower-rate consolidation loan can reduce the interest you pay. This only helps if you stop adding new balances.
- Call your card issuer. Asking for a lower APR sometimes works, especially with a good payment history.
- Put windfalls to work. Tax refunds and bonuses can wipe out a debt in one move.
- Keep a small emergency fund. A $1,000–$2,000 buffer (see emergency funds) keeps a surprise bill from landing back on a credit card.
How paying off debt affects your credit score
Paying down credit cards lowers your credit utilization, the share of your available credit you are using, which is one of the biggest factors in your score. Once a card is paid off, keeping the account open (if it has no annual fee) usually helps your utilization and the length of your credit history. More in how credit scores work.
Key takeaways
- Avalanche = highest interest rate first; it saves the most money.
- Snowball = smallest balance first; it delivers faster wins and motivation.
- In our example, the avalanche saved about $245, while the snowball cleared the first debt 16 months sooner.
- Pick the method you will stick with, and look for ways to lower your rates.
