Faleye Consulting is deciding which of two computer systems to purchase. It can purchase stateoftheart equipment (System A) for $22,000, which will generate cash flows of $6,000 at the end of each of the next 6 years. Alternatively, the company can spend $14,000 for equipment that can be used for 3 years and will generate cash flows of $6,000 at the end of each year (System B). If the company’s WACC is 10% and both “projects” can be repeated indefinitely, which system should be chosen, and what is its EAA? Do not round intermediate calculations. Round your answer to the nearest cent.
Choose Project (A or B), whose EAA = $_____
Evaluation of Investment proposal using Equivalent Annual Annuity (EAA) Rule
Here, the both Projects have different useful lives and therefore, the decision can be made on the basis of Equivalent Annual Annuity (EAA)
The Equivalent Annual Annuity (EAA) should be always preferred if the Projects has the different lives or unequal lives. Since, the EAA gives the exact annual net worth of the project whereas the NPV shows the total worth to the shareholders.

Net Present Value (NPV) = Present value of annual cash inflows – Initial investment costs
= $26,131.56  $22,000
= $4,131.56
Equivalent Annual Annuity (EAA) of PROJECTA
Equivalent Annual Annuity (EAA) = Net Present Value / (PVIFA 10%, 6 Years)
= $4,131.56 / 4.355261
= $948.64

Net Present Value (NPV) = Present value of annual cash inflows – Initial investment costs

= $921.11
Equivalent Annual Annuity (EAA) of PROJECTB
Equivalent Annual Annuity (EAA) = Net Present Value / (PVIFA 10%, 3 Years)
= $921.11 / 2.486852
= $370.39
DECISION
Choose Project A, whose EAA = $948.64
We should select PROJECTA, since it has the higher Equivalent Annual Annuity of $948.64 as compared to the Equivalent Annual Annuity of ProjectB.
NOTE
The formula for calculating the Present Value Inflow Factor (PVIF) is [1 / (1 + r)^{n}], where “r” is the Discount Rate/Cost of capital and “n” is the number of years.
