This sum is then divided by the number of months in a loan to determine the monthly payment. For example, a 10% add-on rate for 36 months on $3000 means add one-tenth of $3000 for 3 years (300 x 3) - usually called the "finance charge" - for a total of $3900. The monthly payment is $3900/36. This keystroke procedure converts an add-on interest rate to a annual percentage rate when the add-on rate and number of months are known. 1. Press and press CLEAR . 2.

Add-On Interest Rate Converted to APR
An add-on interest rate determines what portion of the principal will be
added on for repayment of a loan. This sum is then divided by the number
of months in a loan to determine the monthly payment. For example, a
10% add-on rate for 36 months on $3000 means add one-tenth of $3000
for 3 years (300 x 3) - usually called the "finance charge" - for a total of
$3900. The monthly payment is $3900/36.
This keystroke procedure converts an add-on interest rate to a annual
percentage rate when the add-on rate and number of months are known.
