Chapter 06: Borrowing Money

Overview

In this chapter, simple interest is calculated for loans using exact and approximate time with exact and ordinary interest. Monthly payments for add-on loans are calculated, and the annual percentage rate (APR) is estimated by the constant-ratio formula. Discount loans are introduced and the proceeds calculated. Amortized loans are presented with amortization tables, and formulas are developed for finding the amount a person can borrow for a particular monthly payment and the payment required to borrow a specific amount. The workings of credit cards are explored. The process of bank underwriting is also explored with a look into the five areas that lenders review before issuing a loan.
