How this calculator works
The calculator estimates the number of months needed to pay off a balance based on interest and your recurring payment. If your payment is too low to cover interest, the balance will not decrease.

About this calculator

- Add the annual interest rate charged on the balance.

Frequently asked questions
Why does a small payment keep me in debt longer?
Because a larger share of the payment may go toward interest instead of principal, especially when rates are high.
Can I use this for multiple debts at once?
This version models one balance at a time. For multiple debts, compare each one separately.
What if my interest rate changes?
Variable rates can change the result over time, so this tool should be treated as a simplified estimate.
