14 Four Ways to Find FVsStep-by-step approach using time line (as shown in Slides 7-10).Solve the equation with a regular calculator (formula approach).Use a financial calculator.Use a spreadsheet.
15 Financial calculator: HP10BII Adjust display brightness: hold down ON and push + or –.Set number of decimal places to display: Orange Shift key, then DISP key (in orange), then desired decimal places (e.g., 3).To temporarily show all digits, hit Orange Shift key, then DISP, then =.
16 HP10BII (Continued)To permanently show all digits, hit ORANGE shift, then DISP, then . (period key).Set decimal mode: Hit ORANGE shift, then ./, key. Note: many non-US countries reverse the US use of decimals and commas when writing a number.
17 HP10BII: Set Time Value Parameters To set END (for cash flows occurring at the end of the year), hit ORANGE shift key, then BEG/END.To set 1 payment per period, hit 1, then ORANGE shift key, then P/YR.

65 Nominal rate (INOM)Stated in contracts, and quoted by banks and brokers.Not used in calculations or shown on time linesPeriods per year (M) must be given.Examples:8%; Quarterly8%, Daily interest (365 days)
66 Periodic rate (IPER )IPER = INOM/M, where M is number of compounding periods per year. M = 4 for quarterly, 12 for monthly, and 360 or 365 for daily compounding.Used in calculations, shown on time lines.Examples:8% quarterly: IPER = 8%/4 = 2%.8% daily (365): IPER = 8%/365 = %.
67 The Impact of Compounding Will the FV of a lump sum be larger or smaller if we compound more often, holding the stated I% constant?Why?
68 The Impact of Compounding (Answer) LARGER!If compounding is more frequent than once a year--for example, semiannually, quarterly, or daily--interest is earned on interest more often.
69 FV Formula with Different Compounding Periods INOMFVN = PVMM N
70 $100 at a 12% nominal rate with semiannual compounding for 5 years INOMFVN = PVMM N0.12FV5S = $22x5= $100(1.06)10 = $179.08
71 FV of $100 at a 12% nominal rate for 5 years with different compounding FV(Ann.)= $100(1.12)5= $176.23FV(Semi.)= $100(1.06)10= $179.08FV(Quar.)= $100(1.03)20= $180.61FV(Mon.)= $100(1.01)60= $181.67FV(Daily)= $100(1+(0.12/365))(5x365)= $182.19
72 Nominal vs. Effective Rates (APR vs. EAR or Eff) $100 today, 10% nominal rate compounded annually vs. semi-annually.
73 Effective Annual Rate (EAR = EFF%) The EAR is the annual rate that causes PV to grow to the same FV as under multi-period compounding.
74 Effective Annual Rate Example Example: Invest $1 for one year at 12%, semiannual:FV = PV(1 + INOM/M)MFV = $1 (1.06)2 = $EFF% = 12.36%, because $1 invested for one year at 12% semiannual compounding would grow to the same value as $1 invested for one year at 12.36% annual compounding.
75 Comparing RatesAn 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.
76 EFF% for a nominal rate of 12%, compounded semiannually INOMM= − 10.122= (1.06)= = 12.36%.
77 Finding EFF with HP10BIIType in nominal rate, then Orange Shift key, then NOM% key (in orange).Type in number of periods, then Orange Shift key, then P/YR key (in orange).To find effective rate, hit Orange Shift key, then EFF% key (in orange).
78 EAR (or EFF%) for a Nominal Rate of 12% (APR) EARAnnual = 12%.EARQ = 2 p/yr = %.EARM = 12 p/yr = %.EARD(365) = 365 p/yr = %.
79 Can effective rate ever be equal to nominal? Yes, but only if annual compounding is used, i.e., if p/yr = 1.If p/yr > 1, EFF% will always be greater than nominal.
80 When is each rate used? INOM: Written into contracts, quoted by banks and brokers. Not used in calculations or shownon time lines, unless annual compounding.
81 When is each rate used? (Continued) IPER:Used in calculations, shown on time lines.If INOM has semi-annual compounding, then periodic rate is IPER = INOM/2
82 When is each rate used? (Continued) EAR (or EFF%): Used to compare returns on investments with different payments per year.Used for calculations if and only if dealing with annuities where payments don’t match interest compounding periods.
83 Fractional Time Periods On January 1 you deposit $100 in an account that pays a nominal interest rate of %, with daily compounding (365 days).How much will you have on October 1, or after 9 months (273 days)? (Days given.)

91 2nd Method: Treat as an annuity, use financial calculator Find the EFF% (EAR) for the quoted rate:10 shift Nom; 2 sift p/yr; EFF% = ?

94 Comparing Investments 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 % nominal rate, with 365 daily compounding. You plan to leave the money in the bank if you don’t buy the note. The note is riskless.Should you buy it?

96 Three solution methods 1. Greatest future wealth: FV2. Greatest wealth today: PV3. Highest rate of return: EFF%
97 1. Greatest Future Wealth Find FV of $850 left in bank for15 months and compare withnote’s FV = $1,000.FVBank = $850( )456= $ in bank.Buy the note: $1,000 > $
98 Calculator Solution to FV 924.97INPUTSOUTPUTNI/YRPVFVIPER = INOM/M= /365= per day.PMT
99 2. Greatest Present Wealth Find PV of note, and comparewith its $850 cost:PV = $1,000/( )456= $918.95Buy the note: $ > $850
100 Financial Calculator Solution INPUTSOUTPUTNI/YRPVFVPMT/365 =PV of note is greater than its $850 cost, so buy the note. Raises your wealth.
101 3. Rate of ReturnFind the EFF% on note and compare with 7.0% bank pays, which is your opportunity cost of capital:FVN = PV(1 + I)N$1,000 = $850(1 + I)456Now we must solve for I.
103 Using interest conversion P/YR = 365NOM% = (365) = 13.01EFF% = 13.89Since 13.89% > 7.0% opportunity cost,buy the note.

108 Step 4: Find ending balance after Year 1. End bal = Beg bal - Repmt= $1,000 - $ = $697.89Repeat these steps for Years 2 and 3to complete the amortization table.
