Tipswalet. What Is Internal Rate Of Return And How To Calculate It – In business, especially investment, everyone must think about profits. Of course, who really wants to waste their money on an adverse business, right? However, in the investment business, we will be confused about the potential of a business, is it profitable or detrimental?

Do you know, it turns out there is a way to calculate the possibility of an investment that is potential or not. This method is a calculation using a formula that is made as easy as possible for you to understand.

## What Is Internal Rate Of Return

The internal rate of return (IRR) is a calculation method used in capital budgeting to estimate the profitability of potential investments. Basically, the internal rate of return is a discount rate that makes the net present value (NPV) of all cash flows of a particular project equal to zero. IRR calculations depend on the same formula as NPV.

This internal rate of return method is very important. This will be very useful for those who are considering investing in a business. With Internal Rate Of Return, investors will be able to predict the level of success and tempo so that the capital has been reinvested.

In addition, this also helps you to estimate how much profit can be obtained by using a simple and clear formula. We will review further formulas and case studies. However, before that, we will first explain a little more about the sundries in the formula.

## Formula To Calculate IRR

As explained earlier, IRR is a pretty important reference. To make a safe investment decision, you have to take everything into account. This is the main function of the IRR that will help you make a decision. You certainly do not want to lose when investing business capital, right? Okay, let’s look at the structure of the formula for calculating IRR:

The internal rate of return formulas

## How to Calculate Internal Rate Of Return

To calculate IRR using a formula, you must specify an NPV equal to zero and complete the discount rate (r). However, the nature of this formula is still predictive. You will encounter some obstacles in doing calculations. This is what makes the IRR practice cannot be calculated analytically. However, instead, it must be calculated either through trial-and-error or using software programmed to calculate the IRR.

In general, the higher the IRR of the project, the greater the possibility that investors will be profitable. Calculation of the possibility of IRR can be used in various types of investments. Thus the IRR can be used to rank several prospective projects on a relatively even basis. If the assumption is that investment costs are the same between various projects, the project with the highest IRR will probably be considered the best. You can make the best decisions and run the business with potential.

## Another way to calculate the internal rate of return and case study

If you feel difficulties with the formula above, we find another way to calculate the value of IRR accurately. You can use this formula to calculate the potential of a business where your capital will be invested. Tipswalet.com will also provide several case studies that will increase your understanding.

### Calculate the possibility of profitable investment with a simple formula IRR

To calculate the likelihood of profitable investment, you can use the following simple formula:

IRR = lower discount rate + (NPV at lower % rate / distance between 2 NPV) * (Higher % rate – Lower % rate)

To further deepen your understanding and provide you with examples of how to use the formula, we will provide a case study. We will make the calculations as clearly as possible so that you are easier to understand.

### Case study calculation of the Internal Rate Of Return formula

Example 1:
A project is expected to have a Net Present Value of \$ 865 at a discount rate of 20% and a negative NPV of \$ 1,040 at a discount rate of 22%. Calculate IRR.

Settlement:
The distance between 2 NPV = 865 + 1040 = \$ 1,905
IRR = + 20% (865/1905) * (22% – 20%) = 20.91%

Example 2:
The following information relates to Venture Ltd investment projects:
Net Present Value (NPV) at a cost of 25% of capital: \$ 1,714
NPV at a cost of 30% of capital: (\$ 2937)
Calculate Internal Rate of Return.

Settlement:
The distance between 2 NPV = 1714 + 2937 = \$ 4,651
IRR = + 25% (1714/4651) * (30% – 25%) = 26.84%

### Conclusions from the example and the settlement

From the two sample questions and these two solutions, it can be seen if the calculation is done carefully. This is made so that you are more understanding. There are conclusions from examples of case studies accompanied by solutions.

• If the IRR is greater than the cost of capital, accept the project. This means that the possibility of investment from that question benefits investors. You can invest or invest because the IRR value or the possibility of a return is greater than the capital.
• If the IRR is less than the cost of capital, reject the project. This means you have to give up the investment opportunity because it has the potential to make you lose. This is based on the calculation of the IRR that is smaller than the investment capital that you will spend

## Advantage and Deficiency calculate Internal Rate Of Return Formulas

Despite the advantages and being able to provide an assessment that is a reference for the investor’s decision, in fact, the Internal Rate Of Return has several disadvantages that need to be considered. Here we explain, what are the advantages and disadvantages of calculating the IRR formula.

• Pay attention to the time value of money
• Use cash flow as a basis for calculation
• The result is a percentage, so that decision making can make an estimate if r (discount rate) is difficult to know.

### Deficiency:

• The calculation is more difficult if you do not use a computer because it must be tried (trial and error).
• Does not distinguish projects that have different sizes and investment conditions.
• It can’t be done in a hurry. This is because the formula can produce multiple IRRs or not generate an IRR at all.

Well, that was an explanation of what the internal rate of return in business is, especially investment. We have also provided a formula for calculating IRR followed by examples and solutions. Hopefully, it can help you decide on investment business.
