To calculate the payment amount and the total interest of any fixed term loan,
simply fill in the 3 left-hand cells of the first row and then click on "Calc."
Use the other three rows to see what effects are produced by changing any one
of the loan's original variables.
Note: When entering numbers into the data fields only use numbers and applicable decimal points. Entering commas, dollar signs, or any other non-numeric characters will cause an error.
