Assuming a discount rate of 10%, estimate the following:
a) Net Present Value (NPV)
b) Discounted Benefit-Cost Ratio
c) Net discounted Benefit-Cost Ratio
d) Is the project feasible? Explain your answer
(a) Annual net benefit = Annual benefit - Annual cost
NPV is sum of all annual net benefit discounted at 10%, computed as follows.

Cost ($) |
Benefit ($) |
Net Benefit ($) |

PV of Benefit ($) = |
10,932 |
Discounted Benefit-Cost ratio (BCR) = PV of benefits / PV of costs
= $10,932 / $10,826
= 1.01
Note that Discounted BCR and Net Discounted BCR are the same terms.
(c) Since NPV is positive and (Net) Discounted Benefit-Cost ratio is higher than 1, the project is feasible.
