Chapter 5 - Time Value of Money Flashcards
List the 2 ways to calculate interest
- Simple interest
- Compount interest
What is calculated as a percentage of the principal?
Simple interest
What is the formula to find simple interest?
Money invested + (Years x Interest on Investment)
Solve the problem:
If you decide to invest $1,000 in a money market account with a simple interest rate of 10%, how much simple interest will you earn after three years?
1,000 + (3 ( 1,000 x 10%)) = 1,300
What is Compound interest?
Interest on Interest
What is the formula to find the compound interest of the second year?
Year 1 ending balance + interest on interest
Solve the problem:
If you invest $1,000 at an interest rate of 10% compounding for 3 years, what will year 3’s ending balance be?
Year 1: 1,000 + (1,000 x 10%) = 1,100
Year 2: 1,100 + (1,100 x 10%) = 1,210
Year 3: 1,210 + (1,210 x 10%) = 1,331
Ending Balance after 3 years = $1,331
Which type of interest will grow your money more over time?
Compound interest
What is it called when you find the future value of a cash flow or series of cash flows?
Compounding
Which calculator buttons do you use to find the future value?
N, I, PV
What is the future value of an initial $100 after 10 years, if interest = 10%?
N = 10, I = 10%, PV = $100
FV = $259.37
What is it called when you find the present value of a cash flow or series of cash flows?
Discounting
What shows the value of cash flows in terms of today’s purchasing power?
Present Value
Solve the problem:
What is the present value of $1,000 due in 3 years, if interest = 12%?
N = 3, I = 12%, FV = $1,000
PV = $711.78
What is a series of payments made at equal intervals?
An annuity
Which calculator buttons do you use to find an annuity?
N, I, PMT
When are Ordinarity Annuity payments due?
At the end of the period
When are Annuity Due payments due?
At the beginning of the period
Solve the problem:
What is the future value of a 3-year ordinary annuity with annual investment of $200, evaluated at a 10% interest rate?
N = 3, I = 10%, PMT = 200
FV = $662.00
Does an ordinary annuity or a annuity due make more money?
Annuity due because you are making more interest
Which calculator buttons do you use to find compound interest?
N, I, PMT
Solve the problem:
A 20-year-old student saves $5 a day for her retirement. At the end of the year, she invests the accumulated savings ($5 x 365 = $1,825) in a brokerage account with an expected annual return of 12%. How much money will she have when she is 65 years old?
N = 45, I = 12%, PMT = $1,825
FV = $2,478,769.81
