Comparison
Avalanche interest difference: $0.00. Payoff-time difference: 0 months.
Interest accrues monthly at APR ÷ 12. Required minimums are paid first, then the fixed total monthly budget targets the smallest balance (snowball) or highest APR (avalanche). Freed minimum payments remain in that budget. The simulation stops at 1,200 months and rejects a minimum that cannot cover first-month interest.

How the calculation works
Monthly interest
Opening balance × APR ÷ 12, followed by required minimums and the strategy-targeted remaining budget.
Priority
Snowball targets the smallest balance; avalanche targets the highest APR. Freed minimums stay in the fixed monthly budget.
How to use this calculator
- 1Replace the example values with internally consistent inputs.
- 2Review all result cards and any not-applicable state.
- 3Compare multiple scenarios and verify important assumptions independently.
Understanding the result
Avalanche usually minimizes interest for normal positive-APR debts; snowball can change payoff order and timing.
An entered minimum that cannot cover first-month interest is rejected as non-amortizing.
Important limitations
- Outputs are planning estimates and do not include every provider, accounting, financing, tax, legal, or operational factor.
- Invalid divisions are shown as not applicable rather than NaN or Infinity.
- The model uses monthly periodic interest, a 1,200-month bound, and excludes fees, changing rates, delinquency, and settlement.
