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. We'll use ROE to examine KnowBe4, Inc. (NASDAQ:KNBE), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Is ROE Calculated?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for KnowBe4 is:

4.6% = US$1.1m ÷ US$25m (Based on the trailing twelve months to March 2021).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.05 in profit.

Does KnowBe4 Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As shown in the graphic below, KnowBe4 has a lower ROE than the average (13%) in the Software industry classification.

Unfortunately, that's sub-optimal. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. That will make the ROE look better than if no debt was used.

KnowBe4's Debt And Its 4.6% ROE

One positive for shareholders is that KnowBe4 does not have any net debt! So although its ROE isn't that impressive, we shouldn't judge it harshly on that metric, because it didn't use debt. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.

Conclusion

Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
