One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Savita Oil Technologies Limited (NSE:SOTL).
Our data shows Savita Oil Technologies has a return on equity of 15% for the last year. One way to conceptualize this, is that for each ₹1 of shareholders' equity it has, the company made ₹0.15 in profit.
How Do You Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Savita Oil Technologies:
15% = ₹1.2b ÷ ₹8.5b (Based on the trailing twelve months to June 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity Signify?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does Savita Oil Technologies Have A Good Return On Equity?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. If you look at the image below, you can see Savita Oil Technologies has a similar ROE to the average in the Chemicals industry classification (13%).
That isn't amazing, but it is respectable. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares. If you are like me, then you will not want to miss this free list of growing companies that insiders are buying.
Why You Should Consider Debt When Looking At ROE
Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Savita Oil Technologies's Debt And Its 15% ROE
Although Savita Oil Technologies does use a little debt, its debt to equity ratio of just 0.003 is very low. I'm not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.
But It's Just One Metric
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
