The Debt Snowball method is a debt reduction strategy where you pay off your debts in order of smallest balance to largest balance, regardless of interest rate. You pay the minimum monthly payment on all your debts except the smallest one. Any extra money you can scrape together—including your extra monthly budget—is thrown entirely at that smallest debt.
Once the smallest debt is fully paid off, you take the entire amount you were paying toward it (its minimum payment plus any extra money) and apply it to the next smallest debt. As each debt is eliminated, the amount of cash available to roll over increases, creating a "snowball" effect that grows larger and faster with every victory.
This method focuses on psychological momentum. By eliminating small balances early, you get quick wins that build confidence and keep you motivated to stick with the plan.
Debt Snowball vs. Debt Avalanche: Which is Better?
When planning your debt payoff, you will choose between two primary strategies: the Debt Snowball and the Debt Avalanche.
- Debt Snowball (Smallest Balance First): You prioritize debts by size. This provides quick psychological wins and reduces the number of bills you pay each month rapidly.
- Debt Avalanche (Highest Interest Rate First): You prioritize debts by interest rate. You target the debt with the highest interest first, regardless of the balance. This is mathematically optimal and saves the most interest money, but it can take longer to achieve your first fully paid-off account if that debt has a large balance.
Our calculator allows you to toggle between these two strategies side-by-side. You can see the exact difference in your Months to Debt-Free and Total Interest Paid to make an informed, personal decision.

Debt Snowball Calculator Frequently Asked Questions
Why choose the Debt Snowball if the Avalanche saves more money in interest?
While the Avalanche is mathematically optimal, debt repayment is a behavioral challenge, not just a math problem. If you target a large $20,000 student loan at 6.8% interest while ignoring a $1,000 credit card at 18% under the Avalanche method, it could take you 2 years of payments before you see a single debt drop to $0. With the Debt Snowball, you pay off the $1,000 credit card in months, experiencing a psychological win that keeps you committed to the journey.
What should I do if my budget cannot cover my minimum payments?
This calculator requires that your total monthly budget at least covers the sum of all your minimum monthly payments. If it does not, you are in a deficit and risk default. You should contact your creditors immediately to request temporary hardship programs, lower interest rates, or restructured payments to reduce your minimums to a level you can sustain.
Should I stop saving for retirement while paying off debt?
Dave Ramsey's traditional Debt Snowball method recommends stopping all retirement contributions (even employer 401k matches) to maximize the amount of cash thrown at debt. However, many financial planners suggest continuing to contribute up to your employer's match rate (which represents a 100% immediate return on your savings) and then throwing all remaining surplus cash at your debt.
How often should I recalculate my debt snowball?
You should update your debt snowball worksheet or calculator whenever your financial situation changes. This includes receiving a salary raise (which increases your extra monthly payment capacity), receiving a lump-sum windfall (like a tax refund or work bonus that you can throw at the smallest debt), or when a variable interest rate adjusts.
