Free Debt Snowball Calculator - Pay Off Debt Strategically
Calculate your debt payoff timeline using the snowball method and see how extra payments accelerate your path to being debt-free
Formula & Methodology
The snowball method involves paying the minimum on all debts, then applying any extra cash to the debt with the smallest balance. Once that debt is paid off, its minimum payment (plus the extra cash) is rolled over to the next smallest debt, creating a 'snowball' effect that accelerates your payoff timeline.
- Monthly Interest = Balance × (APR / 100 / 12)
- New Balance = Balance + Monthly Interest - Payment
- Snowball Payment = Minimum Payment + Extra Cash (applied to smallest balance)
Worked Example
Using the Debt Snowball Calculator: apply the formula above to your input values. For instance, Monthly Interest = Balance × (APR / 100 / 12), then New Balance = Balance + Monthly Interest - Payment. The tool performs each step instantly and shows the result.
