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 WD-40 Company (NASDAQ:WDFC), by way of a worked example.
Over the last twelve months WD-40 has recorded a ROE of 43%. One way to conceptualize this, is that for each $1 of shareholders’ equity it has, the company made $0.43 in profit.

How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for WD-40:
43% = 65.436 ÷ US$152m (Based on the trailing twelve months to November 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. Shareholders’ equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
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 amount earned after tax 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 WD-40 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, WD-40 has a higher ROE than the average (16%) in the Household Products industry.
That’s clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. 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 retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. 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.
WD-40’s Debt And Its 43% ROE
While WD-40 does have some debt, with debt to equity of just 0.52, we wouldn’t say debt is excessive. When I see a high ROE, fuelled by only modest debt, I suspect the business is high quality. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.
The Key Takeaway
Return on equity is one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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.
Having said that, while ROE is a useful indicator of business quality, you’ll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth — and how much investment is required going forward.
