You can also use this as an introduction to NPV by having the students put –100 in for CF0. When they compute the NPV, they will get –8.51. You can then discuss the NPV rule and point out that a negative NPV means that you do not earn your required return. You should also remind them that the sign convention on the regular TVM keys is NOT the same as getting a negative NPV. The easiest way to work this problem is to use the uneven cash flow keys and find the present value first and then compute the others based on that. CF0 = 0; C01 = 100; F01 = 1; C02 = 200; F02 = 2; C03 = 300; F03 = 2; I = 7; CPT NPV = 874.17 Value in year 5: PV = 874.17; N = 5; I/Y = 7; CPT FV = 1226.07 Value in year 3: PV = 874.17; N = 3; I/Y = 7; CPT FV = 1070.90 Using formulas and one CF at a time: Year 1 CF: FV5 = 100(1.07)4 = 131.08; PV0 = 100 / 1.07 = 93.46; FV3 = 100(1.07)2 = 114.49 Year 2 CF: FV5 = 200(1.07)3 = 245.01; PV0 = 200 / (1.07)2 = 174.69; FV3 = 200(1.07) = 214 Year 3 CF: FV5 = 200(1.07)2 = 228.98; PV0 = 200 / (1.07)3 = 163.26; FV3 = 200 Year 4 CF: FV5 = 300(1.07) = 321; PV0 = 300 / (1.07)4 = 228.87; PV3 = 300 / 1.07 = 280.37 Year 5 CF: FV5 = 300; PV0 = 300 / (1.07)5 = 213.90; PV3 = 300 / (1.07)2 = 262.03 Value at year 5 = 131.08 + 245.01 + 228.98 + 321 + 300 = 1226.07 Present value today = 93.46 + 174.69 + 163.26 + 228.87 + 213.90 = 874.18 (difference due to rounding) Value at year 3 = 114.49 + 214 + 200 + 280.37 + 262.03 = 1070.89 You might point out that you would probably not offer 154,501. The more likely scenario would be 154,500. Calculator: 30*12 = 360 N .5 I/Y 840 PMT CPT PV = 140,105 Where m is the number of compounding periods per year Using the calculator: The TI BA-II Plus has an I conversion key that allows for easy conversion between quoted rates and effective rates. 2nd I Conv NOM is the quoted rate down arrow EFF is the effective rate down arrow C/Y is compounding periods per year. You can compute either the NOM or the EFF by entering the other two p
