Previously, we have discussed financial metrics and why they are important in a business evaluation. Today we will try to focus on a specific metric called “Return on investment” (ROI).
The Return on Investment is one way of valuating an investment. You probably would not like to invest in a business that would give you no return at all. That would be a silly way of losing money. If you do not like your money, please, donate it to someone who does (preferably to a good cause or, if you do not sympathise to any NGO, me). But I guess this is not your case, otherwise you would not be reading this blog now.
So, what does ROI do? Well, it compares the benefits of a project versus its total costs. Therefore, it will be expressed as a percentage, not in monetary units. To calculate it, you have to divide the net income of the project by its costs, or, in a company, by the book value of assets. The formula for it is presented below:
Example: If you have a net income of $ 200 and a book value of assets of $ 100, ROI illustrates that for every $ 1 you invested, you received a net income of $ 2 (ROI = 200%).
You can improve this formula by adjusting the net income by the interest and tax rate. In this case, the formula would be:
Even being an important financial metric for business evaluation, I wouldn’t rely only on the ROI in my analysis, and there are many reasons for it. As you see, the numerator of the formula, the net income, is not totally reliable to determine the company’s success; it doesn’t tell if the operations are or are not profitable. It also does not take into consideration the life length of the project / investment, depreciation rates, capitalization policy, growth rate, and the lag between the cash outflows and inflows.
All these components are important for evaluating an investment; the longer it takes to get the money you invested into a business, the longer you remain without the benefits from the investment made. If you don’t receive cash inflows from the business, you may end up without money to pay your suppliers. In new companies, the growth rate will be bigger. Therefore, if you are comparing a new company to an older one, this financial metric will decrease in utility.
Still, we see this metric being used in many annual reports. Therefore, you should at least know how it’s calculated in order decide if you are using it or not for your business evaluation (it’s especially useful to not be taken advantage of by someone trying to lie to you using statistics and biased parameters). Keep your eyes wide open!
