How much is $100 received at the end of each year forever, at 10% interest, worth today?
$1,000
Today you deposit $1000 in an account paying 6% interest. At the end of years 1, 2, and 3, you will deposit $100 in that account. What is the present value of that stream of cash flows?
$1,267.30 (Reason: $1000 + $100/(1.06)^1 + $100/(1.06)^2 + $100/(1.06)^3 = $1,267.30.)
Find the future value of an annuity of $100 per year for 10 years at 10% per year.
$1,593.75 (First, find the PV by using the 10 year annuity factor: PV = $100 × 10 year annuity factor = $100 × [1/0.1 − 1/0.1x(1.1)^10]= $614.46. To find the future value, multiply $614.46 x (1.1)^10= $1,593.75.)
Today you deposit $1000 in an account paying 6% interest. At the end of years 1, 2, and 3, you will deposit $100 in that account. How much will you have at the end of year 4?
$1,599.94 (Reason: $1000(1.06)^4 + $100(1.06)^3 + $100(1.06)^2 + $100(1.06)^1 = $1,599.94.)
A dollar invested today at 7.5% simple annual interest will be worth _______ one year from now.
$1.075 FV = $1.00 + $0.075
A dollar invested today at 7.5% interest compounded annually will be worth _______ one year from now.
$1.075 (FV = $1.00(1+0.075))
A dollar invested today at 8.0% simple annual interest will be worth _________ three years from now.
$1.24 (With simple interest, the bank calculates interest only on the principal investment: $1.00 + $0.08 + $0.08 + $0.08 = $1.24. Do not confuse this with compound interest, which computes interest earned on interest.)
A dollar invested today at 8.0% interest compounded annually will be worth _______ three years from now.
$1.2597 FV = $1.00(1 + 0.08)^3
Your insurance agent wants to sell you an annuity consisting of 20 equal end of year payments of $10,000 each, starting at the end of this year. Your desired rate of return for investments of this type is 7 percent. What is the most you would pay for this annuity today?
$105,940.14 (PV = 10,000[1/0.07 − 1/0.07(1.07)^20] = 105,940.14.
In 2013, the CPI was about 2.5 times its level in 1981. If the cost of one semester of college was $5,000 in 1981, what should the nominal cost of a semester of college be in 2013, assuming the real price is constant?
$12,500 (2.5 × $5000 = $12,500.)
What is the future value of $100 invested for 4 years at 10% interest?
$146.41 FV = $100 × (1 + r)^t = $100 × (1 + 0.1)^4 = $146.41.
Assume you have $100 to invest today. Investing it at 5% interest compounded annually will yield _______ in 10 years, while investing it at 6% interest compounded annually will yield _______ in 10 years.
$162.89; $179.08
$200 at the end of each year forever at 10% per year is worth how much today?
$2,000.00 ($200/0.10 = $2,000.)
What is the present value of an ordinary annuity that pays $100 per year for 3 years if the interest rate is 10% per year?
$248.69 (100[(1/0.10) − (1/(0.10(1.10)^3))] = 248.69.
You will receive $100 in 1 year, $200 in 2 years, and $300 in 3 years. If you can earn a 7.5% rate of interest, what is the present value of this stream of cash flows? (Please note that you receive nothing immediately—there is no initial payment)
$507.58 (Reason: $100/(1.075)^1 + $200/(1.075)^2 + $300/(1.075)^3 = $507.58.)
You put $100 in the bank now, $200 in the bank a year from now, and $300 in the bank in 2 years. How much money will you have available 3 years from now if you earn a 7.5% rate of interest? (Calculate the future value of this stream of cash flows. Refer to Example 5.6)
$677.85 (Reason: $100 × (1.075)^3 + $200 × (1.075)^2 + $300 × (1.075) = $677.85.)
The present value of $100 paid annually at year-end for 20 years at 10% per year is ______.
$851.36 (100[(1/0.10) − (1/(0.10(1.10)^20))] = 851.36.)
If the interest rate is 10% per year, then what is the present value (PV) of $100 received 1 year from today?
$90.91 PV = $100/1.10 = $90.91
The effective annual interest rate is equal to ______.
(1 + APR/m)^m − 1

Your neighborhood bank is offering investors a money market account that pays 3.5% interest on deposits. If the current annual rate of inflation is 1.2%, how much is the exact real rate for this account?
2.27% ([1.035/1.012] − 1 = 2.27%.)
A mortgage company is advertising a 30 year fixed rate mortgage with monthly payments and an APR of 3.0%. What is the effective annual interest rate of this loan?
3.04% (First, find the monthly interest rate: 0.03/12= 0.0025%. Next, convert this to an annually compounded interest rate: 1 + effective annual rate = (1 + monthly rate)12 = (1 + 0.0025)12 = 1.0304. The effective annual interest rate is 3.04%.)
If a bank account pays a monthly interest rate on deposits of 0.5%, what is the APR the bank will quote for this account?

fixed
The value in t years of an investment made today at interest rate r is called the ___________ of your investment.

immediately
