Notice that as the interest rate increases, the future value (not surprisingly) also increases. At a
given annualized interest rate, the future value increases as the number of compounding periods
per year increases.
24. Suppose you can earn 10% interest compounded annually. How much would you need to
invest today (assume it’s January 31, 2005) in order to have \$1,000 on January 31,
2013?
25. Suppose you can earn 10% interest compounded semi-annually. How much would you need
to invest today January 31, 2005) in order to have \$1,000 on January 31, 2013?
26. At 10% interest compounded quarterly, what is the present value of \$1,000 to be received 8
years from now?

36. Now, duplicate some of these using the effective rates you computed earlier, in order to prove
to yourself that you get the same answer either way.
37. How much must you deposit now at 6% compounded quarterly in order to have \$1,000 in 5
years?
Notice that as the interest rate goes up, the present value goes down, and vice versa. Also, at a
given annualized interest rate, the present value decreases as the number of compounding periods
per year increases. That is, the more frequent the compounding, the higher the effective rate.

Notice that for a given real rate, the spread between the real rate and the nominal rate exceeds the
rate of inflation (except in the case of continuous compounding). This excess increases as inflation
increases.
Prior to attempting problems 60-72, please review examples 13 & 14 of Lecture Topic 4.

73. Nominal rate after tax is 5% times 0.75 =
3.75%. Then subtract inflation, leaving a
negative result, –0.25%. Finally, divide
this by 1.04 (one plus the rate of
inflation), for a result of approximately
–0.24%
The real rate of interest for borrowing is
negative after tax. Furthermore, the after-
tax real return from investing in the CD
would be negative, so borrow the money
74. Easiest approach is to deflate the selling
price, then calculate rate of return. So in
the, FV is 2,500,000, N is 30, I/YR is 6,
P/YR is 1, PMT is 0, compute PV and
obtain \$435,275.33. Second step: change
enter this result as FV. PV is –500000,
compute I/YR. The result is –0.46%,
indicating that in real terms you lost
money on this investment.
Or, you could inflate the purchase price
and then calculate rate of return. Then in
the first step, PV is 500,000, N is 30, I is
6%, P/YR is 1, PMT is 0, compute FV
and obtain \$2,871,745.59. For the
second step change the sign to negative
and enter this result as PV, input the sales
price of 2,500,000 as FV, and compute
interest (don’t forget the sign
convention—either PV or FV must be
negative). The answer again is –0.46%,
indicating that in real terms you lost
money on this investment.
Another alternative is to calculate the
nominal rate and plug it into the Fisher
effect calculation. Then in the first step,
FV is 2,500,000, PV is –500,000, N is 30,
P/YR is 1, PMT is 0, compute interest.
The result is approximately 5.51%. Next,
subtract 6% and divide by 1.06. The
