The Explorer Company has the opportunity to invest in one of two mutually exclusive machines that will produce a product it will need for the foreseeable future. Machine A costs $15 million but realizes after-tax inflows of $6 million per year for 4 years. After 4 years, the machine must be replaced. Machine B costs $20 million and realizes after-tax inflows of $5 million per year for 7 years, after which it must be replaced. The cost of capital is 9%. What is the equivalent annual annuity for each machine? Which machine should the Explorer Company choose and why?
Calculation of Equivalent Annual Annuity of the Each Machine | ||||||
Year | Machine A | Machine B | ||||
Cash Flows | Discount Factor @9% | Discounted Cash Flows | Cash Flows | Discount Factor @9% | Discounted Cash Flows | |
A | B | C = 1/(1+9%)^n | D = B*C | E | F = 1/(1+9%)^n | G = E*F |

NPV | 4438319.262 | 5164764.18 | ||||
Equivilant Annual Annuity of Machine B = [r * NPV] / [1 - (1+r)^-n] | ||||||
= [9% * $4438319.262] / [1 - (1+9%)^-4] | ||||||
= $399,448.7336 / 0.291574789 | ||||||
= $1,369,970.069 | ||||||
= $1,369,970.07 | ||||||
Equivilant Annual Annuity of Machine B = [r * NPV] / [1 - (1+r)^-n] | ||||||
= [9% * $5,164,764.18] / [1 - (1+9%)^-7] | ||||||
= $464,828.776 / 0.45296576 | ||||||
= $1,026,189.66 | ||||||
EAA of Machine A is higher than Machine B | ||||||
Therefore, Machine A should be selected |
