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 Motherson Sumi Systems Limited (NSE:MOTHERSUMI).
Over the last twelve months Motherson Sumi Systems has recorded a ROE of 20%. Another way to think of that is that for every ₹1 worth of equity in the company, it was able to earn ₹0.20.

How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Motherson Sumi Systems:
20% = ₹17.6b ÷ ₹128.4b (Based on the trailing twelve months to June 2018.)
It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.
What Does Return On Equity Mean?
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. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does Motherson Sumi Systems Have A Good ROE?
By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Motherson Sumi Systems has a higher ROE than the average (14%) in the auto components industry.
That’s what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.
How Does Debt Impact ROE?
Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
