Charges interest on the remaining balance, then applies the fixed total payment.
Includes a smaller final payment when needed.

Common questions
Does this include fees or insurance?
No. Enter a balance and payment that already reflect any amounts you want included.
Can I use an irregular payment?
This tool models one fixed monthly payment; irregular payments need a month-by-month estimate.
