Future Value - Amount to which an investment will grow after earning interest.

Compound Interest - Interest earned on interest.

Simple Interest - Interest earned only on the original investment.

Amortization is the process by which a loan is paid off. During that process, the interest and contribution amounts change every month due to the mathematics of compounding.

Construct an amortization schedulefor a $1,000, 10% annual rate loanwith 3 equal payments.

Solve the equation with a regular calculator.

Use tables.Use a financial calculator.Use a spreadsheet.

Financial calculators solve this equation:

There are 4 variables. If 3 are known, the calculator will solve for the 4th.

2- 86Will the FV of a lump sum be larger or smaller if we compound more often, holding interest rate

constant? Why?

LARGER! If compounding is morefrequent than once a year--for example, semiannually, quarterly,or daily--interest is earned on interestmore often.

Rates of Return:We will deal with 3 different rates:

rNom = nominal, or stated, or quoted, rate per year.

rPer = periodic rate.

EAR = EFF% = .effective annual

rate

2- 89

rNom is stated in contracts. Periods per year (m) must also be given.

Examples: 8%; Quarterly 8%, Daily interest (365 days)

2- 90

Periodic rate = rPer = rNom/m, where m is number of compounding periods per year. m = 4 for quarterly, 12 for monthly, and 360 or 365 for daily compounding.

Examples:8% quarterly: rPer = 8%/4 = 2%.

8% daily (365): rPer = 8%/365 = 0.021918%.

2- 91

Effective Annual Rate (EAR = EFF%):The annual rate that causes PV to grow to the same FV as under multi-period compounding.Example: EFF% for 10%, semiannual: FV = (1 + rNom/m)m

= (1.05)2 = 1.1025.

EFF% = 10.25% because (1.1025)1 = 1.1025.

Any PV would grow to same FV at 10.25% annually or 10% semiannually.

2- 92

An investment with monthly payments is different from one with quarterly payments. Must put on EFF% basis to compare rates of return. Use EFF% only for comparisons.

Banks say “interest paid daily.” Same as compounded daily.

EARD(360) = (1 + 0.10/360)360 – 1 = 10.52%.

2- 95Can the effective rate ever be equal to the nominal rate?

Yes, but only if annual compounding is used, i.e., if m = 1.

If m > 1, EFF% will always be greater than the nominal rate.

If rNom has annual compounding,then rPer = rNom/1 = rNom.

Now suppose you leave your money in the bank for 21 months, which is 1.75 years or 273 + 365 = 638 days.

How much will be in your account at maturity?

Answer: Override N = 273 with N = 638.FV = $119.10.

You are offered a note that pays $1,000 in 15 months (or 456 days) for $850. You have $850 in a bank that pays a 7.0% nominal rate, with 365 daily compounding, which is a daily rate of 0.019178% and an EAR of 7.25%. You plan to leave the money in the bank if you don’t buy the note. The note is riskless.

Find the EFF% on note and compare with 7.25% bank pays, which is your opportunity cost of capital:

FVn = PV(1 + r)n

$1,000 = $850(1 + r)456

Now we must solve for r.

Convert % to decimal:

Decimal = 0.035646/100 = 0.00035646.

EAR = EFF% = (1.00035646)365 – 1 = 13.89%.

2- 120

Using interest conversion:

P/YR = 365.

NOM% = 0.035646(365) = 13.01.

EFF% = 13.89.

Since 13.89% > 7.25% opportunity cost,buy the note.
