In the world of investing, you’ll come across many different terms that you may not be familiar with. Truthfully, almost all of these terms will be important to you as you take a closer look at investing. This is why it is crucial that you learn and understand them.
An example of this is the internal rate of return. This term is often mentioned when discussing investments or projects. It is clearly an important factor that every investor must take into account. As a way to better understand this term, let’s look at the definition of the internal rate of return and figure out why it’s such an integral part of every investment in this article.
What is the Internal Rate of Return (IRR)?
The internal rate of return, or IRR, is a metric used to determine the profitability of a project or investment. Basically, it can be an estimate of the financial return that can be expected from a particular undertaking. This implies that the higher the internal rate of return, the better the investment.
In essence, the internal rate of return is expressed as a percentage as it represents the discount rate that is applied to all cash flows to make the net present value (npv) zero. Alternatively, it is sometimes referred to as the discounted cash flow rate of return or DCFROR.
How to Calculate Internal Rate of Return?
There are three ways to calculate the internal rate of return. You can use a financial calculator, try a different approach to discount rates until the NPV equals zero, or use tools, such as Excel, to simplify the process.
What is the Formula of Internal Rate of Return (IRR)?
The formula for internal rate of return (IRR) is as follows:
NPV=t=0n CFt(1+r)t OR $0 = Σ CFt ÷ (1 + IRR)t
In which:
CFt = net after-tax cash inflow-outflows during a single period t
r = potential internal rate of return on alternative investments
t = time period cash flow is received
n = number of individual cash flows
Which Platforms can the Internal Rate of Return be Calculated in?
The internal rate of return is often used in many different fields, but it can be complicated for some people to calculate. Fortunately, there are several platforms that simplify the process for everyone.
One of the most commonly used platforms for determining the internal rate of return is Excel. When it comes to financial tools, Excel offers the IRR function. This makes calculating the internal rate of return of an investment or cash flow much easier. Businesses frequently utilize this function particularly since they can calculate the IRR formula with Excel and see the results immediately. This allows them to compare projects and make decisions accordingly.
What are the Calculation Examples of Internal Rate of Return?
In order to help you better understand the concept of the internal rate of return, here are some examples.
Suppose a company has to choose between two projects based on their profitability. The company has a 10% cost of capital. Here are the cash flow patterns for each:
Project X has an initial outlay of $2,000 and the following:
- Year one = $1,000
- Year two = $900
- Year three = $500
Project Y has an initial outlay = $1,000 and the following:
- Year one = $900
- Year two = $700
- Year three = $400
The company must calculate the IRR for each project. Initial outlay (period = 0) will be negative. Solving for IRR is an iterative process using the following equation:
$0 = Σ CFt ÷ (1 + IRR)t
where:
- CF = net cash flow
- IRR = internal rate of return
- t = period (from 0 to last period)
OR
$0 = (initial outlay * −1) + CF1 ÷ (1 + IRR)1 + CF2 ÷ (1 + IRR)2 + … + CFX ÷ (1 +IRR)X
Using the examples above, the company can calculate IRR for each project as follows:
IRR Project X:
$0 = (−$2,000) + $1,000 ÷ (1 + IRR)1 + $900 ÷ (1 + IRR)2 + $500 ÷ (1 + IRR)3
IRR Project X = 10.90 %
IRR Project Y:
$0 = (−$1,000) + $900 ÷ (1 + IRR)1 + $700 ÷ (1 + IRR)2 + $400 ÷ (1 + IRR)3
IRR Project Y = 52.89 %
With the company’s cost of capital at 10%, it makes sense for management to pursue Project Y while rejecting Project X.
What is the Internal Rate of Return (IRR) Used for?
The internal rate of return is used for evaluating the profitability and efficiency of an investment or project. It is commonly utilized in capital budgeting, savings and loans, as well as for private equity investments. By utilizing this metric, companies and investors are better equipped to identify ventures that can be highly profitable.
What are the Disadvantages of the Internal Rate of Return?
The disadvantages of the internal rate of return range from its complex calculations that ignore the size and future costs of the project, down to its inability to account for practical reinvestment rates. For an average person, calculating the internal rate of return is undeniably complicated. It is no wonder that even seasoned investors are turning to alternative approaches, such as measuring ROI, to determine whether a project will be profitable. Meanwhile, some people use various tools available to calculate IRRs in a more convenient way.
In addition, the internal rate of return does not account for the overall scope of the project, nor its future costs. It focuses only on the projected cash flows generated by a capital injection. Moreover, it assumes that future cash flows can be reinvested at the same rate as the IRR. However, this is not practical since the IRR typically generates high numbers and there are only a few opportunities that can yield such returns. This simply creates a misleading picture for some companies seeking to maximize cash flow in the future.
How does the Internal Rate of Return Affect the Investment Choices?
By estimating or calculating the annual return or loss on a specific investment, the internal rate of return significantly affects the investment choices of companies and investors. Evidently, they rely on this metric to determine the viability of a specific project. Because of this, they can also compare one investment with another, making it easier to decide which is more worthwhile to participate in.
What are the Similar Terms to Internal Rate of Return?
There are many terms similar to the internal rate of return. An example is the modified internal rate of return. The modified internal rate of return, commonly denoted as MIRR, is a financial measure used to assess how attractive a potential investment is. In this metric, a constructive cash flow is assumed to be reinvested into the company’s capital cost, and the initial outlay is funded at the financing cost. MIRR is essentially a revised version of IRR, hence the name.
Along with MIRR, hurdle rate is also a similar term. A hurdle rate is the minimum rate of return a project or investment must generate. Like IRR, the hurdle rate helps investors decide whether or not to allocate funds to a venture. For instance, when the return falls below the hurdle rate, companies are unlikely to proceed with the investment.
On another note, other terms related to IRR include the economic rate of return (ERR) and the return on investment (ROI), the latter of which we will discuss more in the next section. While there is much in common between these terms, it’s important to remember that there can also be some significant differences.
What is the difference between ROI and IRR?
There is a considerable difference between ROI and IRR. For this reason, it is important for everyone not to confuse these two terms. The ROI, also known as return on investment, measures the total growth or amount of returns of a venture.
At first glance, it appears quite similar to the internal rate of return since it also measures the efficiency and performance of a particular investment or project. However, the major difference between the two is the time period involved in the calculation. The return on investment is mainly concerned with the overall return of an investment, from start to finish. On the contrary, the internal rate of return only focused on the investment’s growth rate on an annual basis. Nonetheless, it is crucial for individuals with an interest in investing to understand these terms and their distinctions.
