Debt Snowball Payoff Planner
The debt snowball method prioritizes paying off the smallest balance first, then rolling that freed payment onto the next smallest balance. Although it does not minimize total interest (the avalanche method does), it generates early wins that many people find motivating, which helps them stay on track. Enter up to four debts below with their balances, APRs, and minimum payments, plus any extra monthly amount you can afford. The calculator sorts by balance ascending, simulates month-by-month payoff with payment rolling, and shows total months and interest paid.
Enter up to 4 debts (leave unused rows at 0).

Debt snowball method
Sort debts smallest balance first. Each month: accrue interest = balance * (APR/12/100). Pay minimums on all. Apply extra to smallest balance. When paid off, add freed minimum to extra payment for next debt.
The snowball method does not minimize interest cost but provides early motivational wins by eliminating individual debts sooner than the avalanche method would.
Psychology of debt payoff
Research in behavioral finance, including studies published in the Journal of Marketing Research, shows that paying off individual accounts completely produces a sense of progress that helps people maintain payoff momentum. While the snowball method costs more in total interest than the avalanche, if it prevents you from giving up, it may result in a better real-world outcome. Choose whichever method you will actually stick with for years.
Frequently asked questions
What is the debt snowball method?
The debt snowball method targets the debt with the smallest balance first, regardless of interest rate. Once paid off, you roll that minimum payment onto the next smallest balance, creating a snowball effect of increasing payments.
Does the snowball method save more interest than the avalanche?
No. The avalanche method (highest APR first) always saves more interest. However, studies by behavioral economists show many people stick to the snowball longer because early payoffs provide motivation. The best method is the one you follow consistently.
How do I roll the payment forward?
When debt 1 is paid off, its minimum payment is added to the payment you were already making on debt 2. You do not increase total spending; you just redirect what was going to debt 1 onto debt 2.
Should I stop contributing to savings during snowball payoff?
The CFPB recommends maintaining a small emergency fund (at least $1,000) even while paying off debt, to avoid going back into debt when unexpected expenses arise. Beyond that emergency fund, prioritizing high-interest debt payoff over savings is usually financially beneficial.
Can I combine snowball and avalanche strategies?
Yes. Some people pay off one or two small balances first to reduce the number of accounts and simplify finances, then switch to avalanche order for the remaining debts. There is no rule requiring pure adherence to one method.
