Equipment B :
Present value of estimated cash outflow is:18, 00,000 + (12,000 X 0.8333) + (13,000 X 0.6944) + (14,000 X 0.5787)
+ (14,500 X 0.4823) + (15,000 X 0.4019) = Rs.18, 40,150The present value of estimated cash inflow is:(8, 00,000 X 0.8333) + (7,00,000 X 0.6944) + (6,00,000 X 0.5787) + (5,00,000 X
0.4823) + (4,00,000 X 0.4019) + (1,00,000 X 0.4019) = Rs.19,42,040The NPV in the present case is = 1, 01,890Equipment C :
The PV of estimated cash outflow is:17, 00,000 + (14,000 X 2.9906) = Rs.17, 41,868The PV of cash inflow is:(7, 00,000 X 0.8333) + (7,00,000 x 0.6944) + (6,00,000 X 0.5787) + (6,00,000 X
0.4823) + (3,00,000 X 0.4019) + (50,000 X 0.4019) = Rs.18,46,655The NPV in the present case = 1, 04,787Consider the NPV of 3 equipments together.Equipment A : Rs.2, 63,791Equipment B : Rs.1, 01,890Equipment C : Rs.1, 04,787The decision to purchase should invariably be in favour of Equipment A, even
though its initial cost is higher than that of Equipment B and C.Internal Rate of Return
- IRR must be calculated in order to assess at what point of time in the project the
investor will fully recover his /her initial investment. This point is indicated by
percentage. If NPV = 0, the Present Value of benefits is equal to the Present Value
of costs. The time required to recover initial investment may vary from project to
project. An investor will clearly opt for a project where he/she can quickly recover
the initial investment, when compared to the other projects.
