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

11
Simple Interest

12
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?

13
Example 1 continued First State Bank: E-Save Bank: Johnson City Trust: 4.22% Land Savings Bank: 4.3%

14
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?

15
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?

16
Simple Interest Example 4 How much simple interest does $200 earn in 7 months at an interest rate of 5%

17
Simple Interest Example 5 How much principal must be deposited to earn $1000 simple interest in 2 years at a rate of 5%?

18
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?

19
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?

20
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)

21
Example 1 How much interest would $1000 earn in one year at a rate of 6%, compounded annually? What would be the new balance?

22
Example 2 Maria deposits $1000 in a savings account that pays 6% interest, compounded semiannually. What is her balance after one year?

23
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?

24
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?

25
Compound Interest Formula B=ending balance p=principal r=interest rate N=number of times interest is compounded annually T=number of years

26
Example 1 Marie deposits $1650 for three years at 3% interest, compounded daily. What is her ending balance?

27
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?

28
APY/APR APR-annual percentage rate APY-annual percentage yield Banks usually advertise Higher than APR for accounts compounded more than once per year

29
Annual percentage yield formula r= interest rate N=number of times per year

30
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?

31
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?

32
Continuous Interest B=ending balance P=principal E=exponential base (on Calc) r=interest rate t=number of years

33
Example 1 Craig deposits $5000 at 5.12% interest, compounded continuously for four years. What would his ending balance be to the nearest cent?

34
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?

35
Future value of a periodic deposit investment Periodic investments are the same deposits made at regular intervals such as yearly, monthly, biweekly, etc.

36
Future Value Of A Periodic Deposit

37
Example 1 Rich and Laura are both 45 years old. They want to retire at age 65. They deposit $5000 each year into an account that pays 4.5% interest, compounded annually. What is the account balance when they retire?
