How it works
Months = −ln(1 − r·B/P) ÷ ln(1 + r)
A fixed monthly payment slowly clears a balance while interest accrues. A bigger payment cuts both the time and the total interest sharply.

Frequently asked questions
Why does interest cost so much?
Because it is charged every month on the remaining balance — paying more upfront saves a lot.
What if my payment is too low?
If it does not cover the monthly interest the debt never reduces; increase the payment.
