9. Calculating an installment loan payment using the add-on method

Calculating the loan payment on an add-on interest installment loan

Installment loans allow borrowers to repay the loan with periodic payments over time. They are more common than singlepayment loans because it is easier for most people to pay a fixed amount periodically (usually monthly) than budget for paying one big amount in the future. Interest on installment loans may be computed using the simple interest method or the add-on method.
