What does the Internal Rate of Return (IRR) stand for?
In financial analysis, the internal rate of return (IRR) determines a purchase’s profitability. In a discounted cash flow study, the risk-free rate (IRR) makes the net present value (NPV) of all cash flows equal to zero.
The same method is used to figure out IRR as it is for NPV. Remember that IRR does not mean how much the project is worth in cash. It’s the yearly return that makes the NPV blank.
With few exceptions, investments with a higher internal return are usually better. Because IRR is the same for all kinds of investments, it can rank several possible investments or projects reasonably evenly. Most of the time, the investment with the highest IRR would be considered the best when comparing choices with similar traits.
How to Figure Out Internal Rate of Return
To use the method, one would set NPV to zero and figure out the IRR, which is the discount rate.
The original investment is always negative because it takes money away from the business.
Each following cash flow could be positive or negative, based on how much money the project is expected to bring in or need.
However, IRR can’t be easily calculated mathematically because of how the formula is written. Instead, it has to be calculated iteratively, either by trial and error or by using software designed to calculate IRR, like Excel.
How to Use Excel to Figure Out Internal Rate of Return
The IRR is easy to figure out with the IRR function in Excel. It’s easy to find the discount rate you want with Excel because it does all the work for you. All you have to do is use the IRR function to add up your cash flows, including the original investment and the money that comes in afterward. You can find the IRR method by clicking the Formulas Insert (fx) icon.
Here is a simple example of an IRR study with known cash flows that happen once a year. Let’s say a company determines if Project X will make money. The project needs $250,000 to get started and is supposed to bring in $100,000 after taxes in the first year and another $50,000 every year for the next four years.
The IRR is 56.72% in this case, which is pretty high.
The XIRR and the MIRR are two other tools in Excel that can be used to figure out the IRR. XIRR is used when the cash flow model doesn’t have exact yearly cash flows. The MIRR is a way to measure the rate of return that considers both the risk-free rate and the cost of capital.
How to Understand Internal Rate of Return
The main goal of IRR is to find the discount rate that equals the original net cash outlay for the investment to the present value of the sum of the annual nominal cash flows. There are several ways to find an expected return, but IRR is often the best way for a company to look at the possible return of a new project it wants to start.
IRR is the growth rate that an investment should bring in each year. In this way, it can be like a compound annual growth rate (CAGR). Most of the time, a purchase won’t have the same rate of return every year. Most of the time, the return rate that an investment earns will be different from its expected IRR.
Why would you use IRR?
One everyday use of IRR in capital planning is to compare how profitable it is to start new businesses versus how profitable it is to grow current businesses. An energy company might use IRR to determine whether to build a new power plant, fix it, or add it to an old one.
Both projects might benefit the business, but IRR says one will probably be the wiser choice. Remember that IRR isn’t always good enough for long-term projects where discount rates are likely to change because it doesn’t consider changing discount rates.
Companies can also use IRR to evaluate schemes that buy back their stock. Suppose a company spends a lot of money to buy back its shares. In that case, the research must clearly show that the company’s stock is a better investment (has a higher IRR) than any other use of the money, like opening new stores or buying other businesses.
People can also use IRR to make financial choices, like comparing insurance policies based on death benefits and premiums. Almost everyone agrees that plans with high IRR and the same premiums are better.
Pay attention to the fact that life insurance has a very high IRR in the first few years—often more than 1,000%. After that, it goes down over time. When the insurance is set up, this IRR is very high because your beneficiaries would still get a lump sum even if you only pay one monthly premium.
IRR is also often used to look at the profits of investments. Most of the time, the promised return will assume that any cash dividends or interest payments are put back into the investment. What if you don’t want to reinvest your returns but need the money when it comes in? If returns aren’t supposed to be returned to the business, are they paid out or kept in cash? How much do you think the cash will earn? Regarding products like annuities, where the cash flows can get complicated, IRR and other assumptions are very important.
Finally, IRR is a way to determine a property’s money-weighted rate of return (MWRR). If you want to know what rate of return you need to start with, the MWRR helps you by considering all the changes in cash flows during the investment time, such as sales proceeds.
How to Use IRR and WACC
An IRR analysis will usually examine a company’s weighted average cost of capital (WACC) and net present value (NPV). Since IRR is usually pretty high, it can reach zero NPV using this method.
Most companies will want the IRR to be higher than the WACC. WACC is a way to determine how much a company costs to get capital. It does this by giving each type of capital an equal amount of weight. A WACC calculation considers all types of capital, such as common stock, preferred stock, bonds, and any other long-term debt.
An IRR bigger than the cost of capital means the project should make money. Companies often set a required rate of return (R) when planning investment projects. This is the lowest return percentage the investment must make to be considered worthwhile. The WACC will be less than the RRR.
If a project’s IRR is higher than its RRR, it’s likely to be successful, but that’s not always enough to get a company to work on it. They will likely go after projects with the most significant difference between IRR and RRR instead since those are likely to make them the most money.
You can also compare IRR to current rates of return in the stock market. If a company can’t find any projects with an IRR higher than the gains it can get from the stock market, it may decide to put its money in the market instead. When setting an RRR, market gains can also be taken into account.
NPV calculations at different discount rates are also a standard part of analyses.
Annual Growth Rate vs. Internal Rate of Return
The CAGR shows the annual return on an investment over a length of time. The IRR is also an annual rate of return, but the CAGR only needs a starting value and an ending value to estimate the yearly rate of return.
IRR is different because it considers more than one periodic cash flow. This is because stocks often have cash coming in and going out constantly. One more difference is that CAGR is simple enough to be easy to figure out.
What is the difference between IRR and ROI?
Analysts and businesses may also look at the return on investment (ROI) when they decide how to spend their cash.ROI tells an owner how much their investment grew from the beginning to the end. It’s not a rate of return per year. IRR tells the owner how much the business grows every year. The two numbers will not stay the same for more extended periods. They will stay the same for one year.
ROI is how an investment grows or shrinks from start to finish. To find it, divide the difference between the current or projected future value and the starting value by the starting value and then multiply by 100.
You can determine the return on investment (ROI) for almost any action where you put money into something and measure the result. However, ROI isn’t always the best measure in the long term. It also doesn’t work well for capital planning, mostly about looking at regular cash flows and returns.
What IRR Can’t Do
Most of the time, IRR is the best way to look at capital planning projects. People can get the wrong idea about it if they use it in the wrong situations. The IRR could have more than one number if there are positive cash flows, negative ones, and positive ones. Also, if all the cash flows have the same sign (that the project never makes money), then no discount rate can make the NPV equal to zero.
The internal rate of return (IRR) is a common way to estimate a project’s yearly profit, but it’s not always meant to be used by itself. Since IRR is usually pretty high, it can reach zero NPV using this method. The IRR is just an estimated number that gives you an idea of the yearly return value. Most analysts choose to mix IRR analysis with scenario analysis because estimates of IRR and NPV can be very different from the actual results. NPVs can be different in different scenarios if different assumptions are made.
As was already said, IRR and NPV studies are not enough for most businesses. These figures are often looked at along with a company’s WACC and an RRR, giving us more information.
IRR analysis is often compared to other choices by businesses. If there is a similar IRR for another project that needs less up-front cash or fewer other factors that need to be considered, then the more straightforward investment may be chosen despite the IRR.
Sometimes, using IRR to compare projects of different lengths can go wrong. One example is a project that will only last a short time but has a high IRR, which makes it look like a significant investment. On the other hand, a project that takes longer may have a low IRR because it earns profits more slowly. The ROI measure can help simplify things in these situations, but some managers might not want to wait longer.
How to Invest Based on IRR
The internal rate of return rule helps you decide whether to proceed with a business or project. The IRR rule says that a project or business can go forward if the IRR is higher than the minimum R, which is usually the cost of capital.
If, on the other hand, the IRR on a project or investment is less than the cost of cash, it might be best to turn it down. Even though IRR has some flaws, it is generally accepted as a standard way to look at capital budgeting projects.
Example of IRR
Let’s say a business is looking over two projects. The people in charge must choose which one, both or neither, to move forward with. The cost of cash for it is 10%. Here are the cash flow trends for each:
Plan A
The initial cost is $5,000.
One year = $1,700
The second year costs $1,900.
Three years = $1,600
Four years = $1,500
Five years = $700
Plan B
The initial cost was $2,000.
The first year costs $400.
Two years = $700
The third year costs $500.
Four years = $400
Five years = $300
For each job, the company has to figure out the IRR. The first payment (period = 0) will be less than zero. Using the following equation, you can solve for IRR over and over again:
$0 equals ¿ CFt times (1 + IRR)t.
in which places
CF stands for “net cash flow.”
Inside return rate, or IRR
Period (from 0 to last period) is equal to t.
-or-
$0 = (deposit amount minus 1) + CF1 ÷ (1 + IRR)1 + CF2 ÷ (1 + IRR)2 +… Plus CFX times (1 plus IRR)X
The company can figure out IRR for each project by using the examples above:
Project A IRR
-$5,000 plus $1,700 times (1 + IRR)1 and $1,900 times (1 + IRR)2 and $1,600 times (1 + IRR)3 and $1,500 times (1 + IRR)4 and $700 times (1 + IRR)5
IRR for Project A is 16.61 percent.
Project B IRR
$0 equals (-$2,000) + $400 (1 + IRR)1 + $700 (1 + IRR)2 + $500 (1 + IRR)3 + $400 (1 + IRR)4 + $300 (1 + IRR)5
IRR for Project B is 5.23 percent
Since the company’s capital cost is 10%, managers should move forward with Project A and turn down Project B.
In what way does the Internal Rate of Return help me?
A financial tool called the internal rate of return (IRR) determines how good an investment chance is. An investment’s internal rate of return (IRR) estimates that investment’s rate of return after considering all of its expected cash flows and the value of money over time. When choosing between several possible investments, the investor would pick the one with the best IRR, as long as it was higher than their minimum threshold. The biggest problem with IRR is that it relies too much on guesses about future cash flows, which are notoriously hard to do.
IRR and ROI are not the same thing.
For convenience, IRR is sometimes called a project’s “return on investment,” but this is not how most people use that term. When people talk about ROI, they usually mean the percentage return an investment gives in a year or over. However, that kind of ROI doesn’t show as many details as IRR. That’s why investment professionals usually choose IRR.
IRR is also better than ROI because its meaning is mathematically precise, while ROI can mean different things based on the person speaking or the situation.
What is a good return on investment (IRR)?
A person can decide if an IRR is good or bad based on the potential cost and the cost of capital. For example, a real estate owner might go after a project with a 25% IRR if other similar real estate investments offer 20% or less returns. But this comparison is based on the idea that these problematic investments are about the same in terms of how risky they are and how much work they require. If an investor can get a slightly lower IRR from a much less risky project or takes much less time, they might gladly take on the lower-IRR project. If everything else stays the same, a higher IRR is usually better than a lower one.

- IRR is a great way to look at capital planning projects and compare and understand the possible rates of return each year over time.
- Companies use IRR to choose which capital projects to fund, and buyers can use it to determine the return on investment of different assets.
