So, estimated cash flow must be converted into present value. It can be defined as the difference between total present value and net cash outlay. It is determined as following.
Net present value (NPV) = Total present value – Net cash outlay

- NPV helps in maximizing the firm’s value.
- NPV is difficult to use.
- NPV cannot give accurate decision if the amount of investment of mutually exclusive projects is not equal.
- It is difficult to calculate the appropriate discount rate.
