Types of Interest
Interest is based on interest rate and
principal (balance)
 Simple interest is calculated on principal
only
 Compound interest is money earned on
the money deposited plus previous
interest

Simple Interest
I  prt
I=Interest
p=principal
r=interest rate
t=number of years
Example 1 Simple interest

Grace wants to deposit $5000 in a
certificate of deposit for a period of two
years. She is comparing interest rates
quoted by three local banks and one
online bank. Write the interest rates in
ascending order. Which bank pays the
highest interest for this two-year CD?

Simple Interest example 2

Raoul’s Savings account must have at
least $500, or he is charged a $4 fee.
His balance was $716.23, when he
withdrew $225. Will he be charged a
fee?
Simple Interest Example 3

Mitchell deposits $1200 in an account
that pays 4.5% simple interest. He
keeps the money in the account for three
years. How much is in the account after
three years?
Simple Interest Example 4

How much simple interest does $200
earn in 7 months at an interest rate of
5%
Simple Interest Example 5

How much principal must be deposited
to earn $1000 simple interest in 2 years
at a rate of 5%?
Simple Interest Example 6

Derek has a bank account that pays
4.1% simple interest. The balance is
$910. When will the account grow to
$1000?
Simple Interest Example 7

Kerry invests $5000 in a simple interest
account for 5 years. What interest rate
must the account pay so there is $6000
at the end of 5 years?
Compound Interest Terms
Annual compounding-once each year
 Semiannual Compounding-twice a year
 Quarterly compounding-4 times a year
 Daily compounding-365 times a year
(366 in a leap year)

Example 1

How much interest would $1000 earn in
one year at a rate of 6%, compounded
annually? What would be the new
balance?
Example 2

Maria deposits $1000 in a savings
account that pays 6% interest,
compounded semiannually. What is her
balance after one year?
Example 3

How much interest does $1000 earn in
three months at an interest rate of 6%,
compounded quarterly? What is the
balance after three months?
Example 4

How much interest does $1000 earn in
one day at an interest rate of 6%,
compounded daily? What is the balance
after one day?


Marie deposits $1650 for three years at
3% interest, compounded daily. What is
her ending balance?
Example 2

Kate deposits $2350 in an account that
earns interest at a rate of 3.1%,
compounded monthly. What is her
ending balance after five years?
APY/APR
APR-annual percentage rate
 APY-annual percentage yield

Banks usually advertise
 Higher than APR for accounts compounded
more than once per year

Annual percentage yield formula

per year

Example 1

Sharon deposits $8000 in a one year CD
at 3.2% interest, compounded daily.
What is Sharon’s annual percentage
yield (APY) to the nearest hundredth of a
percent?
Example 2

Barbara deposits $3000 in a one year
CD at 4.1% interest, compounded daily.
What is the APY to the nearest
hundredth of a percent?
Continuous Interest
B=ending balance
 P=principal
 E=exponential base (on Calc)
 r=interest rate

Example 1

Craig deposits $5000 at 5.12% interest,
compounded continuously for four years.
What would his ending balance be to the
nearest cent?
Example 2

If you deposit $1000 at 4.3% interest,
compounded continuously, what would
your ending balance be to the nearest
cent after five years?
Future value of a periodic
deposit investment
