The Internal Rate of Return (IRR) method evaluates investment projects by calculating the rate at which the net present value (NPV) of cash flows from the project equals zero. For independent projects, those with an IRR greater than the required rate of return (or cost of capital) should be accepted, as they are expected to generate value. Conversely, projects with an IRR below this threshold should be rejected, as they would diminish value. The underlying logic is to maximize shareholder wealth by selecting projects that yield returns exceeding the cost of capital.
How is the method superior to the payback method
Advantages: a. It will give the correct decision advice assuming a perfect capital market. It will also give correct ranking for mutually exclusive projects. b. NPV gives an absolute value. c. NPV allows for the time value fo the cash flows. Disadvantages: a. It is very difficult to identify the correct discount rate. b. NPV as method of investment appraisal requires the decision criteria to be specified before the appraisal can be undertaken.
The Net Present Value (NPV) method is generally regarded by academics as the best single method for evaluating capital budgeting projects. This is because NPV accounts for the time value of money, providing a clear measure of the projected profitability of a project by discounting future cash flows to their present value. A positive NPV indicates that a project is expected to generate value over its cost, guiding investment decisions effectively. Additionally, it aligns with the goal of maximizing shareholder wealth.
The IRR rule states that if the internal rate of return (IRR) on a project or investment is greater than the minimum required rate of return - the cost of capital - then the decision would generally be to go ahead with it. Conversely, if the IRR on a project or investment is lower than the cost of capital, then the best course of action may be to reject it.
Why is the NPV approach often regarded to be superior to the IRR method?
In the IRR method, the intermediate cash inflows are assumed to be consumed and so are not reinvested. The unmodified IRR method, as compared with the NPV method, will not show the superiority of any two mutually exclusive investments with two different initial outlays. In such a case, an investment with lower IRR could have a higher NPV and therefore should be chosen by an investor. In some cases where there are streams of positive and negative cash flows in an investment, the IRR method may yield more than one IRR. This is not a disadvantage if the calculations are performed correctly.
Advantages:With the NPV method, the advantage is that it is a direct measure of the dollar contribution to the stockholders.With the IRR method, the advantage is that it shows the return on the original money invested.Disadvantages:With the NPV method, the disadvantage is that the project size is not measured.With the IRR method, the disadvantage is that, at times, it can give you conflicting answers when compared to NPV for mutually exclusive project.BY SHARANYA NV
IRR: Internal rate return NPV: Net present value Both are measure of the viability of a project(s) You can have multiple IRR (because of discontinued cash flows) but you always have one NPV.

NPV (Net Present Value) and IRR (Internal Rate of Return) can yield different conclusions when evaluating projects with non-conventional cash flows, such as multiple sign changes in cash flows, or when comparing mutually exclusive projects with different scales or time horizons. NPV is generally preferred for its absolute value indication of profitability, while IRR can be misleading in such cases, potentially suggesting a higher return on a less favorable project. Additionally, if the cost of capital is higher than the IRR, a project may still be rejected based on NPV, which reflects the actual value added.
IRR is measured in terms of %age and not in absolute measures. It is the breakeven discount rate and is preferred where management is interested in evaluating the project in terms of %age. It enables the management to compare it to the inflation rate, cost of capital or investment and with other accounting ratios. If NPV or absolute return is same in large and small investment, then IRR method is preferred in choosing the investment. Because in this case, IRR gives the %age of return and a project with higher IRR is recommended.
Problems with project ranking: 1. Mutually exclusive projects of unequal size (the size disparity problem) - the NPVdecision may not agree with the IRR or PI. Solution: select the project with the larges NPV (not IRR). 2. The time disparity problem with mutually exclusive projects - NPV and PI assume cash flows are reinvested at the required rate of return for the project. IRR assumes cash flows are reinvested at the IRR. NPV decision may not agree with the IRR. Solution: select the project with the largest NPV. A good method to evaluate and rank project better is to use the Equivalent Annual Annuity (EAA) method. This is like calculating for PMT when doing TVM. It simply means, you will be getting that amount as an inflow each year or period. Therefore, you would want to choose the highest figure.
NPV measures the return a project generates against the costs borne to generate them, while also considering Time Value of Money. Whereas IRR measures returns alone and is hence seen as a myopic metric. NPV will be positive only when the IRR>WACC (i.e. the returns are more than the costs). The concept of IRR being greater than WACC is also called 'Positive EVA'. Needless to say, a project must be selected when NPV > 0! When choosing between projects, the spread between IRR & WACC will determine the financial feasibility ...the higher the better.
