This calculator applies the snowball method across multiple debts, throwing every extra dollar at the smallest balance first for quick wins. Use it to build a motivating payoff plan when clearing whole debts fast matters more to you than squeezing out the last bit of interest savings.
How this is calculated
Each month it adds interest at APR divided by 12 to every debt, pays each minimum, then directs the remaining pooled payment to the debt with the smallest balance first, rolling freed-up payments forward until every balance reaches zero.
How to use
- Enter the balance, APR, and minimum payment for each of your debts.
- Enter the extra amount you can put toward debt each month.
- Read the months to debt-free, total interest, and total paid.
Examples
- Three debts + $200 extra:
28 months to debt-free - Smallest first:
$1,000 balance cleared before $5,000
FAQ
- How does the debt snowball method work?
- You pay the minimum on every debt, then throw all your extra money at the debt with the smallest balance. When it is paid off, you roll its payment into the next-smallest balance, creating a growing "snowball".
- Why pay the smallest balance first instead of the highest rate?
- The snowball prioritizes quick wins for motivation. Paying the highest interest rate first (the avalanche method) saves more money, but clearing small debts fast keeps many people on track.
- What if my payments are too low?
- If your minimum payments plus extra do not cover the monthly interest, the debts never clear. The calculator will tell you the total payment is too low.
