Snowball vs Avalanche: Which Debt Method Should You Pick?
The avalanche method saves the most money: pay off the highest interest rate first. The snowball method gives faster wins: pay off the smallest balance first. Both work. Pick the one you will stick with.
What are the snowball and avalanche methods?
Both methods start the same way. You pay the minimum on every debt. Then you put all your extra money on one debt, called the target.
Avalanche method is paying off debts from the highest interest rate to the lowest.
Snowball method is paying off debts from the smallest balance to the largest.
When the target debt is gone, its payment does not disappear. It moves to the next debt on your list. That is why the payment grows over time, like a snowball rolling downhill.
The US consumer regulator, the CFPB, describes both. It says to pay all your minimums first, then add the extra to one debt, then move that amount on when the debt is paid off.
Which one saves more money?
The avalanche. Interest is the cost of borrowing. (See what is interest.) The debt with the highest rate costs you the most each month, so clearing it first stops the biggest leak.
The CFPB says paying the highest-rate debts first saves you money overall. It also says the snowball may cost more in the long run.
How much more depends on your debts. If your rates are close, the gap is small. If one rate is much higher, the gap is bigger.
What does this look like with real numbers?
Say you have four debts. You pay €660 a month in total: €510 of minimums plus €150 extra.
| Debt | Balance | Yearly rate | Minimum |
|---|---|---|---|
| Visa card | €4,200 | 19.9% | €120 |
| Car loan | €9,800 | 6.5% | €260 |
| Student loan | €3,100 | 3% | €90 |
| Phone plan | €640 | 0% | €40 |
Step 1. Find each monthly interest. The formula in words: balance times the yearly rate, divided by 12.
- Visa: 4,200 × 19.9% ÷ 12 = about €70
- Car: 9,800 × 6.5% ÷ 12 = about €53
- Student: 3,100 × 3% ÷ 12 = about €8
- Phone: €0
That is about €130 of interest in month 1. The Visa is more than half of it.
Step 2. Each month, add the interest, then pay. Minimums go to every debt. The €150 extra goes to the target.
Step 3. When a debt is gone, its whole payment moves to the next target.
Here is what happens, month by month, until every debt is gone:
| Plan | Order | Debt-free in | Total interest |
|---|---|---|---|
| Avalanche | Visa, Car, Student, Phone | 30 months | €1,802 |
| Snowball | Phone, Student, Visa, Car | 31 months | €2,271 |
| No extra (€510 a month) | Highest rate first | 41 months | €3,092 |
The avalanche saves €469 and one month compared with the snowball.
Both beat paying no extra. The avalanche saves €1,290 and 11 months against that plan. That is the real win: the extra €150 a month does more than the order you choose.
Why do people still pick the snowball?
Because it feels like progress, sooner.
In this example, the snowball clears the phone plan in month 4. The avalanche does not clear its first debt until month 16, when the phone plan ends on its own.
That is a year without a win. For some people, that is when they give up.
Australia’s government money site, Moneysmart, says paying the smallest debt first helps keep you motivated. It also says to consider the highest-rate card first if one rate is much higher.
The CFPB says to choose the plan that motivates you most.
How do I choose?
Ask yourself one question: what makes me quit?
- If it’s a slow start, pick the snowball. The quick wins keep you going.
- If it’s wasted money, pick the avalanche. You will pay the least.
- If you can’t decide, start with the avalanche. If two rates are about the same, pay the smaller balance first.
Whichever you pick, the extra payment matters most. Even €50 more a month helps. (See how to find €100 a month.)
And keep paying every minimum. If a minimum is below its monthly interest, that debt will grow while you work on the others. (See the minimum payment trap.)
Do this today (10 minutes)
- List every debt with its balance, yearly rate and minimum payment.
- Sort the list twice: once by rate (highest first), once by balance (smallest first).
- Pick one order, choose your extra amount, and put it on the first debt.

FAQ
Which saves more money, snowball or avalanche? The avalanche method. It sends extra money to the debt with the highest interest rate, so less interest builds up. In the example in this post, it saved €469 and one month compared with the snowball. The gap gets bigger when your rates are far apart.
Is the snowball method a mistake? No. It costs a little more, but it gives you quick wins. In the example, the first debt was gone in month 4 with the snowball, against month 16 with the avalanche. If seeing a debt disappear keeps you going, that can be worth the extra cost.
Do I still pay the minimum on my other debts? Yes. Both methods start the same way. Pay the minimum on every debt, every month, so nothing falls behind. Only the extra money goes to one target debt. When that debt is gone, its payment moves to the next one on your list.
What if two debts have the same interest rate? Pay the smaller one first. You get the quick win of the snowball and lose nothing on interest, because both debts cost the same. This mix of both methods is a simple, safe way to start if you can’t decide.
