Calculating IRR
Calculating IRR, or internal rate of return, is a method used to evaluate the potential profitability of an investment. It represents the discount rate at which the net present value of cash flows from the investment equals zero. By comparing the IRR to a company's required rate of return, decision-makers can assess whether an investment is financially viable.

...Calculating Internal Rate of Return WHAT IT MEASURES Technically, the interest rate that makes the present value of an investment’s projected cash flows equal to the cost of the project. In practice, Internal Rate of Return (IRR) is the rate that indicates whether or not an investment is worth pursuing. WHY IT IS IMPORTANT The calculation of internal rate of return (IRR) is used to appraise the prospective viability of investments and capital projects. It is also called dollar-weighted rate of return. Essentially, IRR allows an investor to find the interest rate that is equivalent to the monetary returns expected from the project. Once that rate is determined, it can be compared to the rates that could be earned by investing the money elsewhere, or to the weighted cost of capital. IRR also accounts for the time value of money. HOW IT WORKS IN PRACTICE How is IRR applied? Assume, for example, that a project under consideration costs $7,500 and is expected to return $2,000 per year for five years, or $10,000. The IRR calculated for the project would be about 10 percent. If the cost of borrowing money for the project, or the return on investing the funds elsewhere, is less than 10 percent, the project is probably worthwhile. If the alternate use of the money will return 10 percent or more, the project should be rejected, since from a financial perspective it will break even at best. Typically, management requires an IRR equal to or higher than the cost of capital, depending on relative risk and other factors. The best way to compute an IRR is by using a spreadsheet (such as Excel) or financial calculator, which do it automatically, although it is crucial to understand how the calculation should be structured. Calculating IRR by hand is tedious and time-consuming, and requires the process to be repeated to run sensitivities. If using Excel, for example, select the IRR function...

...But this is not only difficult, because as we all know from the stock market, the success rate of past investments is not a good indicator for future performance and should therefore not influence today’s decisions. And what is even more important is, as the ROI calculation formula is not uniformly defined, the business case team could run the danger of comparing apples with pears. 2.5 INTERNAL RATE OF RETURN (IRR) The internal rate of return (IRR) is a handy measure which is frequently used in finance departments. However, as the examples in this chapter will show, it can also be a very misleading metric. IRR is defined as the rate of return that makes the NPV zero. In order to find the IRR for a proposed investment, the following equation needs to be solved: There is no ambiguity in calculating the IRR for an investment that only generates one single cash flow after one period. In fact, the calculation is pretty simple: The expression for longer investment periods is much more difficult, if not impossible, to solve arithmetically and usually requires a trial-and-error linear interpolation approach, for which a spreadsheet such as the one in Figure 2.6 comes very handy. Let us revert to the previous real estate example and modify it a little: After an initial investment of $470,000 into real estate, the investor now expects a rental income of $30,000 p.a. There is a plan to sell the real estate in the fifth year for $500,000. A trial-and-error interpolation, as shown in Figure 2.9 using the NPV formula results in an IRR ≈ 6.38%, which is the rate of discount at which the investment’s NPV becomes zero (NPV = 0)...

...However, extended discussions may be found among the writings of contemporary financial management texts. Some initiatives may require periods that are longer than those that are considered in this text. When these situations occur, it is recommended that IRR calculations be performed through the use of software spreadsheets, proprietary software, or financial calculators. Also, within the context of collegiate finance courses, a tabular solution is also available to solve IRR problems involving a variety of periods. However, for the purposes of this text, the use of the basic formula is appropriate to demonstrate the basic concept of the internal rate of return, and to delineate the calculations through which IRR problems are solved. Future editions of this text, if any, are anticipated to contain the tabular solution methods of IRR problems. 7.7 Chapter Comments and Summary This chapter introduced the internal rate of return (IRR) method of capital budgeting. The methods of capital budgeting encompass perspectives of time, cash value, rate, and profitability potential. The IRR is indicative of a rate-based perspective regarding the rendering of capital budgeting decisions. Further, the IRR method incorporates the time value of money within its primary construct. Derivation of the IRR method may occur through algebraic manipulation of the net present value formula that is given in Chapter 6. Although the outcomes of the IRR method present quantitative findings, the outcomes must be interpreted. The rules governing the interpretation of the IRR outcome are quite basic: 1. Accept the capital initiative if the value of the calculated IRR outcome is higher than the specified discount rate. 2. Reject the capital initiative if the value of the calculated IRR outcome is lower than the discount rate. 3...

...If th is is not the case, then allowance can be made by reducing the income streams before discounting by their probability factor. For exa mple, if a n income stream of €400,000 was only 95 per cent certain to be realized, then a value of €380,000 (400,000 × 95 per cent) might be used. The internal rate of return (IRR) The internal rate of return (IRR) is the discount rate that produces a zero NPV. If the IRR is greater than the company’s cost of capital, the project should be undertaken using this criterion. The IRR is an easily understood measure but it does not demonstrate the relative size of projects. However, it is widely used. Calculating the IRR by simple interpolation Example A company has identified an opportunity costing €1,350,000 with the following income stream: Year Cash flow 1 + €700,000 2 + €750,000 It has a cost of capital of 3 per cent. What is the IRR and should the company undertake the project? Solution Year Cash flow (€) 4% PV (€) 5% PV (€) 0 –1,350,000 1.000 –1,350,000 1.000 –1,350,000 1 + 700,000 0.962 + 673,400 0.952 + 666,400 2 + 750,000 0.925 + 693,750 0.907 + 680,250 NPV + 17,150 NPV – 3,350 Steps By experimentation, find the discount rates that give a positive NPV and a negative NPV when applied to the cash flow. In this case you will find that these are 4 per cent and 5 per cent. A 4 per cent discount rate gives a NPV of + €17,150. A 5 per cent discount rate gives a NPV of –€3,350. The internal rate of return must, therefore, lie between 4 per cent and 5 per cent. Using interpolation we can see that a 1 per cent move has resulted in a –€20,500 change in NPV...

...It only says whether a project has a positive NPV or negative NPV. Hence, several companies also use IRR for capital budgeting decisions, as it gives an idea about the expected returns of a project. IRR also needs net cash flows to start with. It is best to calculate IRR using Microsoft Excel as shown below. We use the excel formula, “IRR”, as shown in the cell A5 below: Project A gives a return of 18.59%, whereas, Project B gives a 12.16% return. Hence, if they are mutually exclusive, then Project A should be selected. Below is the IRR for the other example project: Years 0 1 2 3 Net cash flow ($135,000) $46,000 $46,000 $106,000 IRR 18.61% The IRR of 18.61% above should be higher than the cost of capital for the project to be accepted. If the cost of capital is 10% then there is a good safety margin. However, if the cost of capital is 18%, then it is risky to undertake the project as a small deviation in the estimated cash flows could make the project give a return lower than the cost of capital. There are some issues with project selection when using IRR for mutually exclusive projects. Projects of different sizes or those with different cash flow timings can lead to an incorrect project selection decision when using IRR. In such cases, NPV is a better option to make a decision. There are also cases when a project has multiple IRRs. This happens when there are large cash outflows in the later years of the project. Once again, in such cases, NPV is a better measure to use. 4.8 Modified Internal Rate of Return (MIRR) In order to resolve the above issues with IRR, another method called Modified IRR has been developed. MIRR for a project is calculated using the MIRR function in Microsoft Excel as shown below. We use the excel formula, “MIRR”, as shown in cell A5 below: The 10% used in the above calculation is the cost of capital...

...A lower value is preferred over a higher value. Net Present Value (NPV) – It calculates the current (or present) value of future cash flows using discounted cash flows. NPV should be equal to or greater than zero to select a project. Internal Rate of Return (IRR) – Similar method as NPV but gives a percentage return as output. IRR should be greater than cost of capital (hurdle rate) to select a project. Modified IRR can be used to resolve issues with IRR for mutually exclusive projects. *****...

...Academics have long argued that investment criteria employing the time value of money, such as NPV and IRR, are superior to those that do not, and that NPV is a superior investment criterion to IRR because IRR possesses pitfalls. Brealey et al. (2011) contains a classic statement of the arguments and lists four pitfalls. 1 An IRR, by itself, does not indicate whether a project involves borrowing or lending; 2 Some cash flows cause the IRR equation to solve for more than one plausible IRR, resulting in ambiguity about which IRR to use as a criterion; 3 NPV and IRR do not always rank mutually exclusive projects the same; the consensus opinion is that ranking by NPV is reliable, and therefore ranking by IRR is not; 4 A non-flat yield curve provides more than one cost of capital with which to compare IRR leading to uncertainty about which cost of capital to employ. Despite the pitfalls there is considerable empirical evidence that the majority of practitioners continue to use IRR as an investment criterion and performance measure. For example, in the context of capital budgeting there is the study of US data by Graham and Harvey (2001) and the similarly executed study of European data by Brounen et al. (2004). Many studies of capital budgeting practice are published every year containing similar results for various countries. In the context of IRR as a performance measure for private equity firms, hedge funds, and venture capitalists see the works by Phalippou (2008), Phalippou and Gottschalg (2009), Dichev and Yu (2011), and Achleitner et al.

...CHAPTER 7 Net Present Value and Internal Rate of Return Now that we have completed your introduction to Crystal Ball, we will begin looking at several different types of situations for which Crystal Ball models are useful. We start with net present value (NPV) models, and see situations where the distribution of NPV can help decision makers gain insights into the problem at hand. We will also consider the pros and cons of using internal rate of return (IRR) as a Crystal Ball forecast. It is assumed that you are already familiar with these concepts. For more background information on NPV and IRR in deterministic models, see any introductory finance textbook such as Melicher and Norton (2011). 7.1 DETERMINISTIC NPV AND IRR Suppose that you have the opportunity to purchase an annuity that costs you $100 at Year 0, and is certain to return $30 to you at the end of each Year, 1 through 5. These cash flows are depicted in the Excel chart on the spreadsheet segment in Figure 7.1. Denote the cash flow at the end of Year t as C t, and the relevant annual rate of interest as r. Then the net present value (NPV) of the annuity is defined as (7.1) FIGURE 7.1 Spreadsheet segment to model annuity with deterministic cash flows of at the end of Year 0, and at the end of Years 1 through 5. For the cash flows in Figure 7.1, if r =10 percent then as shown in cell B11. Therefore, the annuity is a good investment for any individual with a required minimum rate of return of 10 percent because the investment’s NPV of $13.72 is greater than zero at that rate. Be aware that the definition of NPV in Equation 7.1 is slightly different from that used by the Excel NPV function. To find the NPV of the annuity in Figure 7.1, we use the Excel formula (7.2) which is entered in cell B11 of NPV.xls. Most finance textbooks refer to the quantity calculated in this example by Excel’s NPV function as the present value at end of Year 0 of the cash flows obtained at the ends at Years 1 through 5...
