Net present value is the difference of Sum of Present values of cash inflows and Sum of Present values of cash outflows. If the value is positive then the project may be accepted. While evaluation of two or more alternatives takes place, then the proposal with the higher net present value may be selected since it results in a greater
In the given scenario, Present values are calculated by calculating the present values of cash outflows such as installation cost and operating cost.
Present value factor is calculated as 1/1.10 ^ N where N is the year of operation of the refrigerator.
Deferment of capital expenditure to Year 10 in case of Option 2 results in a lower overall cash outflow despite increase in the annual operating costs from years 11-30. This is owing to the present value factor.
Conclusion:
Hence the Option to be implemented is Option 2 since it results in lower overall cash outflow.

Net cash outflow | 39,997.78 |
Net present value is the difference of Sum of Present values of cash inflows and Sum of Present values of cash outflows. If the value is positive then the project may be accepted. While evaluation of two or more alternatives takes place, then the proposal with the higher net present value may be selected since it results in a greater cash inflow over the duration of the project.
In the given scenario, Present values are calculated by calculating the present values of cash outflows such as installation cost and operating cost.
Present value factor is calculated as 1/1.10 ^ N where N is the year of operation of the refrigerator.
Deferment of capital expenditure to Year 5 in case of Option 2 results in a higher overall cash outflow due to increase in the annual operating costs from years 6-30. This is owing to the present value factor.
Conclusion:
Hence the Option to be implemented is Option 1 since it results in lower overall cash outflow.
