Debt Avalanche Calculator guide
What it is for
The Debt Avalanche Calculator estimates a financial outcome so you can compare scenarios before making a decision.
How it is calculated
The aggregate payoff model adds monthly interest and subtracts each payment until the balance reaches zero, counting months and the exact final payment. It does not rank separate debts.
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.
