Debt Snowball Calculator guide
What it is for
The Debt Snowball Calculator estimates a financial outcome so you can compare scenarios before making a decision.
How it is calculated
Each month adds balance × annual percentage / 1200 in interest, applies the payment, and repeats until the balance is paid. The final payment is capped at the amount owed.
Assumptions
Taxes, fees, inflation, rate changes, and product terms are not included unless the inputs account for them.
Example
Worked example — Total debt balance: $10000; Average annual interest rate: 18%; Monthly debt payment: $400. Estimated payoff time (months): 32; Interest paid (exact final payment): $2,627.927997.
Limitations
This is an aggregate-balance payoff estimate, not a multi-debt snowball or avalanche schedule. It does not order debts by size or rate. Consult a financial professional before choosing a repayment plan.
