While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we’ll use ROE to better understand Kogancom Limited (ASX:KGN).

Our data shows Kogan.com has a return on equity of 29% for the last year. Another way to think of that is that for every A$1 worth of equity in the company, it was able to earn A$0.29.

How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Kogan.com:

29% = AU$14m ÷ AU$48m (Based on the trailing twelve months to June 2018.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders’ equity is a little more complicated. 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 ROE Mean?

ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Kogan.com Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Kogan.com has a superior ROE than the average (12%) company in the online retail industry.

That is a good sign. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.

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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Kogan.com’s Debt And Its 29% ROE

One positive for shareholders is that Kogan.com does not have any net debt! Its impressive ROE suggests it is a high quality business, but it’s even better to have achieved that without leverage. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
