Time Value of Money

Interest is the rent paid for the use of money over time.

That’s right! A dollar today is more valuable

than a dollar to be received in one year.

Simple Interest

Interest amount = P × i × n

Assume you invest $1,000 at 6% simple interest for 3 years.

You would earn $180 interest.

($1,000 × .06 × 3 = $180)

(or $60 each year for 3 years)

Compound Interest

When we compound interest, we assume you earn interest on both principal and interest.

Multiply a year’s beginning principal by the interest rate and add that year’s interest to the

account balance.

$1,000.00 × 1.06 = $1,060.00 and

Some notes do not include a stated interest rate. We call these notes

noninterest-bearing notes.

Even though the agreement states it is a noninterest-bearing note, the note

does, in fact, include interest.

We impute an appropriate interest rate for a loan of this type to use as the interest rate.
