Loan Basics
The principal is the amount of money
owed at any particular time.

Interest is charged on the loan principal.

To pay off a loan, you must gradually pay
down the principal. Each payment should
include all the interest plus some amount
that goes toward paying off the principal.

Suppose you want to pay off a loan with regular
(equal) monthly payments in a certain amount of
time. Use Loan Payment Formula (pg 252)
