As investors, we need to understand how our companies truly make their money. A neat trick developed for just that purpose -- the DuPont formula -- can help us do so.
The DuPont formula can give you a better grasp on exactly where your company is producing its profit, and where it might have a competitive advantage. Named after the company where it was pioneered, the formula breaks down return on equity into three components:
Return on equity = net margin x asset turnover x leverage ratio
What makes each of these components important?
High net margins show that a company can get customers to pay more for its products. Luxury-goods companies provide a great example here.
High asset turnover indicates that a company needs to invest less of its capital, since it uses its assets more efficiently to generate sales. Service industries, for instance, often lack big capital investments.
Finally, the leverage ratio shows how much the company is relying on liabilities to create its profits.
Generally, the higher these numbers, the better. That said, too much debt can sink a company, so beware of companies with very high leverage ratios.
Let's see what the DuPont formula can tell us about Career Education (NAS: CECO) and a few of its sector and industry peers:
Return on Equity
DeVry (NYS: DV)
American Public Education (NAS: APEI)
ITT Educational Services (NYS: ESI)

The returns on equity range from solid to spectacular, with these for-profit educators putting up strong performances in margins and asset turnover. While Career Education's ROE is at the bottom of the pack here, it's still a solid performer without using significant leverage. DeVry's fatter margin drives ROE higher, and it looks very similar to American Public. ITT leads th is group in margin, asset turnover, and leverage -- making its ROE look truly gaudy.
Using the DuPont formula can often give you some insight into how a company is competing against peers and what type of strategy it's using to juice return on equity.
