Relationship between NPV and IRR
NPV is obtained by discounting all the cash flows by the required rate of return.
It is calculated by summing the present value of the net benefits for each year over a specified period of time, then subtracting the initial costs of the project. A positive NPV means that the project generates a profit, while a negative NPV means that the project generates a loss.
IRR equals the percentage rate by which the net benefits have to be discounted until the point that they equal the initial costs. IRR is closely related to net present value. The rate of return calculated by IRR is the discount rate one would need to apply to the benefits of the project to obtain a net present value of zero.
If we discount all the cash flows at the IRR rate we get an NPV of zero. Or equivalently, the IRR is a discount …
