The debt snowball method pays off your smallest debt first while you pay the minimums on everything else. When the smallest is gone, its payment rolls into the next one, so the amount you put toward debt grows like a snowball. It usually costs a bit more interest than the avalanche method, but early wins help many people stick with the plan.
What is the debt snowball method?
The debt snowball is a payoff strategy, popularized by personal finance author Dave Ramsey, where you list debts from smallest to largest balance, pay minimums on all of them and put every extra dollar on the smallest one. Each time a debt is paid off, you add its payment to the next one.
How do I use the debt snowball calculator?
- List every debt — credit cards, medical bills, personal and car loans, student loans. Leave out your mortgage if you plan to pay it on schedule.
- Enter the balance, APR and minimum payment from your latest statements.
- Add an extra monthly amount you can pay consistently, even $25.
- Calculate and look at the payoff order and debt-free date.
- Compare with avalanche to see the interest difference.
- Set the payments up. Automate minimums; schedule the extra payment for payday.
What does a debt snowball plan look like?
Three debts totaling $10,800, with $340 in minimum payments and $150 extra each month — $490 a month toward debt.
| Debt | Balance | APR | Minimum |
|---|---|---|---|
| Medical bill | $800 | 0% | $50 |
| Credit card | $3,000 | 24% | $90 |
| Car loan | $7,000 | 6.5% | $200 |
| Snowball | Avalanche | Minimums only, no extra | |
|---|---|---|---|
| First debt paid off | Medical bill, month 4 | Credit card, month 15 | Medical bill, month 16 |
| Debt-free | Month 25 | Month 25 | Month 39 |
| Total interest | ≈ $1,200 | ≈ $1,090 | ≈ $2,250 |
In this example, avalanche saves about $115 in interest; snowball gives you the first win 11 months earlier. Both cut more than a year and about $1,000 in interest compared with paying only the minimums. Your own numbers will differ — that's what the calculator is for.
Assumes fixed rates, monthly interest and freed-up minimums rolled into the next debt.
Is the debt snowball or avalanche faster?
Mathematically, the avalanche method — highest interest rate first — always costs the same or less in interest and is never slower. The snowball method can still work better in practice, because closing small debts quickly keeps people motivated.
| Snowball | Avalanche | |
|---|---|---|
| Pays first | Smallest balance | Highest interest rate |
| Total interest | Same or higher | Lowest |
| First win | Usually sooner | Can take longer |
| Best for | People who need momentum | People who stay motivated by numbers |
Research supports the motivation effect. In an analysis of debt-settlement data, David Gal and Blakeley McShane (Journal of Marketing Research, 2012) found that closing individual accounts — regardless of their size — predicted paying off all debt. And Keri Kettle, Remi Trudel and colleagues (Journal of Consumer Research, 2016) found that concentrating payments on one account made people feel more progress and work harder toward repayment.
How do I stick with a debt payoff plan?
- Automate the minimums so a busy week never causes a late fee.
- Schedule the extra payment for the same day each month, right after payday.
- Celebrate each closed debt — that's the point of the snowball.
- Stop adding new debt. Put cards away while you pay them down. - Keep a small buffer. A starter emergency fund stops one surprise from undoing months of work - Track the plan. A debt payoff app or a recurring task with a reminder keeps the monthly step from slipping.
If your minimum payments are more than you can manage, contact your lenders or a nonprofit credit counseling agency before you miss payments. For decisions about consolidation, bankruptcy or taxes, talk to a licensed professional.
Can an app help me pay off debt?
Yez3 doesn't connect to your bank or pay your bills — it keeps the plan moving. The monthly extra payment becomes a recurring task on your Minimum, a reminder fires on payday, and if it's still open near the end of the day, the AI coach checks in and asks what's in the way. Small weekly steps — cancel one subscription, sell one item — go on the plan too.
Debt snowball calculator FAQ
Does the debt snowball really work?
For many people, yes. It doesn't minimize interest, but it gives quick wins that keep you going, and research on consumer debt found that closing individual accounts predicted paying off debt overall. The best method is the one you'll stick with until every balance is zero.
Is debt snowball or avalanche faster?
The avalanche method, which pays the highest interest rate first, is never slower and usually costs less interest. The difference is often small when rates are similar. Snowball closes your first debt sooner, which can matter more if you've struggled to stay motivated before.
How long will it take to pay off my debt?
It depends on your balances, rates, minimum payments and how much extra you add each month. Enter your debts in the calculator above to see your debt-free date. Even a small extra payment, like $50 a month, can cut months off the plan.
Should I include my mortgage in the debt snowball?
Usually not. The debt snowball is typically used for consumer debts like credit cards, medical bills and car or personal loans. A mortgage is usually paid on its normal schedule. If you're unsure, talk to a licensed financial professional.
Should I save or pay off debt first?
Many people keep a small starter emergency fund first, so an unexpected bill doesn't go on a credit card, then focus on debt. The right balance depends on your rates, income stability and situation — a licensed professional can help you decide.
