Debt Snowball Calculator

Use the Debt Snowball Calculator

Your results

Total debt: $0.00
Total minimum payments: $0.00
Estimated payoff time: 0 months
Suggested payoff order: Enter at least one debt

How this calculator works

What it does: Build a debt snowball plan that targets the smallest balance first and rolls freed minimum payments into the next debt.
Inputs used: The estimate uses debt 1 balance, debt 1 minimum monthly payment, debt 2 balance, debt 2 minimum monthly payment, debt 3 balance, debt 3 minimum monthly payment, and extra monthly payment.
Calculation approach: The calculator applies the relationships defined for the debt snowball calculator to those inputs and updates total debt, total minimum payments, estimated payoff time, and suggested payoff order.
How to read the result: Treat the result as a scenario based on the values entered. Compare a few reasonable inputs and consider costs, taxes, timing, or risks that the calculator does not include.

How to Use This Calculator

Enter Debt 1 balance, Debt 1 minimum monthly payment, and Debt 2 balance using values that match the scenario you want to evaluate.
Enter Debt 2 minimum monthly payment, Debt 3 balance, and Debt 3 minimum monthly payment using values that match the scenario you want to evaluate.
Enter Extra monthly payment using values that match the scenario you want to evaluate.
Review the assumptions for the debt snowball calculator, especially rates, time periods, and optional amounts.
Select Calculate to update the results, then adjust one input at a time to compare scenarios.

Understanding the Results

Total debt: The total debt estimated by the Debt Snowball Calculator using debt 1 balance, debt 1 minimum monthly payment, and debt 2 balance and the other values entered.
Total minimum payments: The total minimum payments estimated by the Debt Snowball Calculator using debt 1 balance, debt 1 minimum monthly payment, and debt 2 balance and the other values entered.
Estimated payoff time: The estimated time needed to reach the target under the current contribution, payment, and growth assumptions.
Suggested payoff order: A plain-language comparison based only on the assumptions entered; it is not a guarantee or personal recommendation.

Common Mistakes

Entering an annual interest rate as a monthly rate, or leaving out fees and required payments.
Assuming the quoted monthly payment includes taxes, insurance, or other costs when it may cover principal and interest only.
Ignoring whether a payment is high enough to cover the interest added each month.
Comparing payments without also comparing payoff time and total cost.

Worked Example

Example inputs

Debt 1 balance: $1,500
Debt 1 minimum monthly payment: $75
Debt 2 balance: $5,000
Debt 2 minimum monthly payment: $150
Debt 3 balance: $10,000
Debt 3 minimum monthly payment: $250
Extra monthly payment: $100

Example results

Total debt: $16,500.00
Total minimum payments: $475.00
Estimated payoff time: 2 years, 5 months
Suggested payoff order: Debt 1 -> Debt 2 -> Debt 3

With these example payments and rates, the estimated payoff time is 2 years, 5 months. Actual payoff timing can change with fees, rate changes, missed payments, or additional charges.

Frequently asked questions

What is the debt snowball method?

The debt snowball method pays minimums on every debt while directing extra money to the smallest balance. After that debt is cleared, its payment rolls into the next-smallest debt.

Why target the smallest balance first?

Clearing a small debt can create an early, visible win and simplify your monthly obligations. That momentum is the main behavioral advantage of the snowball method.

Does this calculator include interest?

This first version models simple monthly principal reduction and does not include interest. Actual payoff time may be longer when balances accrue interest.

What happens to a paid-off debt payment?

Its minimum payment remains in your fixed monthly debt budget and is redirected to the next active debt, making the snowball larger over time.

How is debt snowball different from debt avalanche?

Snowball prioritizes the smallest balance for motivation. Avalanche prioritizes the highest interest rate and generally minimizes interest when all other assumptions are equal.

What does the Debt Snowball Calculator calculate?

Build a debt snowball plan that targets the smallest balance first and rolls freed minimum payments into the next debt. The result is based only on the inputs and assumptions shown on the page.

How should I interpret the total debt from the Debt Snowball Calculator?

Use it as an estimate for the scenario entered, not as a guarantee or personal recommendation. Test changes to debt 1 balance, debt 1 minimum monthly payment, and debt 2 balance to see which assumptions have the greatest effect.
