Debt to Equity Ratio – Meaning, Assumptions and Interpretation
The debt to equity ratio is the most important of all capital adequacy ratios. It is seen by investors and analysts worldwide as the true measure of riskiness of the firm. This ratio is often quoted in the financials of the company as well as in discussions pertaining to the financial health of the company […]
Two Period Dividend Discount Model
The next step towards understanding the dividend discount model is to extend the conclusions derived from the single step dividend model. This brings us to the two period dividend discount model. In this model we will use the same logic. However, we will extend the assumption regarding the holding period. Instead of selling his stock […]
What is Annuity? – Meaning and Concept
An annuity, just like a perpetuity, is a shortcut used while making present value calculations. Unlike the perpetuity, which is very difficult to find in real life, we find examples of annuity all around us. The monthly mortgage payments we make, the car loan or student loan that we pay off are all annuities. Annuities […]
Causes for Cost Overruns in Infrastructure Projects
In the previous article, we explained the concept of cost overrun. We also explained how cost overruns have a negative effect on the finances of the entire project. However, it is strange that despite being so harmful to infrastructure projects, cost overruns are still ubiquitous. It is common for more than 50% of megaprojects to […]
Importance of Different Ratios to Different User Groups
As we have seen earlier that there is a wide variety of financial ratios available. They fall into many categories and if variations are included there are hundreds of types of ratios that are common in practice. However, all the ratios are not used by everyone on a regular basis. There are some ratios which […]
The Internal Rate of Return (IRR) is another very important metric that can be used to determine whether or not a company must invest its resources in a project. If the company does decide to invest its resources in all the projects then the IRR can help us understand what should be the priority of these projects for the company.
Let’s understand Internal Rate of Return (IRR) with the help of an example. Let’s say that we have an investment that pays $10 on a $100 investment. So, we can clearly see that the rate of return is 10%. This means 10% of the money invested will be recouped every single time period. But this calculation was simple because there was only one return we received and we just had to calculate its size as compared to the original investment.
Now, consider the fact that for the same $100 investment, you are going to receive $20 for the first 2 years, $30 for the next 2 years and $50 in the 5th year. So what would be the rate of return for this investment? So here we are taking a complex schedule of cash outflows and inflows and we are basically coming up with a single rate that describes the rate of return. In the above example the rate of return is 13%.
This means that if we invested $100 and got a consistent rate of interest which was compounded at 13%, then that investment would be equivalent to the above investment. The above investment provides the same return as that of a bond with an annual coupon of 13%. This is the Internal Rate of Return (IRR) of the investment.
The calculation of Internal Rate of Return (IRR) with a formula is very complex and is never used in practice. We generally use financial calculators or MS Excel both of which have inbuilt IRR functions to find out the IRR.
The relationship between the IRR and the NPV is very important. In fact, it could be the defining characteristic of IRR. IRR is the rate at which NPV of the project is zero. This is clearly intuitive. Consider the fact that the rate of growth of your investment and the discount rate both will be the same in this case. Therefore they will nullify each other and the NPV will be zero at IRR.
The rule pertaining to the IRR is simple. A company must decide a hurdle IRR rate. Let’s say the hurdle rate is 10%. So, the company must then choose investments that pay over 10% and must reject investments that pay less than 10%. In the above example 13% is greater than 10% and hence the investment must be selected. In case the company wants to choose between 2 projects both of which have more than 10% return, then the one with the higher Internal Rate of Return (IRR) must be selected.
The IRR metric is also flawed. But its flaws are smaller as compared to the payback period method. It is for this reason that many companies do in fact use the IRR method to decide amongst investments. It is a little bit more intuitive to use. Its flaws have been discussed in the forthcoming article.
