How the debt payoff estimate works
The calculator uses your balance, APR, monthly payment, and any extra payment to estimate a fixed-payment payoff timeline. It assumes the interest rate and payment stay consistent and that no new charges are added.
The result is most useful for comparing scenarios: increase the monthly payment, add a one-time plan outside this tool, or see how a small extra amount changes the estimated timeline.
- Pay more than the monthly interest so the balance can fall.
- Keep a cash buffer before sending every available dollar to debt.
- Check your statement for fees, promotional rates, and changing APRs.
Snowball versus avalanche planning
A debt snowball usually prioritizes the smallest balance for a quick win. A debt avalanche usually prioritizes the highest APR to reduce interest mathematically. This calculator models one balance at a time, so use it to compare payments before choosing a broader strategy.
