It's the second factor in the DuPont decomposition, and answers a different question than margin: not how much profit each sale leaves, but how many sales the company is able to generate with the resources it has. High asset turnover indicates a company makes good use of its assets to generate revenue, regardless of its margin -- businesses with low margins, like large retail, usually offset it with very high asset turnover."},"relations":{"requirement":[],"contrast":[],"related":[{"concept":{"id":56,"slug":"dupont-decomposition","term":"DuPont decomposition","shortDefinition":"A method that splits ROE into three factors -- margin, asset turnover, and leverage -- to understand where a company's profitability really comes from.","longDefinition":"The DuPont decomposition splits ROE into three multiplicative factors: net margin (how much profit is left from each euro of revenue), asset turnover (how much revenue each euro of assets generates, a measure of efficiency), and financial leverage (how much of the assets are financed with debt relative to equity). Multiplied together, these three factors exactly reconstruct ROE. Its usefulness lies in the fact that two companies can have the same ROE for completely different reasons -- one from selling with a high margin, another from being very efficient with its assets, another from being more leveraged -- and DuPont lets you tell which of those stories is the real one, instead of settling for a single figure that blends them all together."}}],"calculatedBy":[{"concept":{"id":43,"slug":"assets","term":"Assets","shortDefinition":"Everything a company owns and controls at a given instant -- from cash and inventory to machinery and buildings.","longDefinition":"Assets are everything a company owns and controls at the instant the balance sheet reflects: cash, accounts receivable, inventory, machinery, buildings, brands, stakes in other companies.

The DuPont decomposition answers exactly that question, splitting ROE into three multiplicative factors that, together, exactly reconstruct it.\n\nThe first factor is net margin -- already covered in general terms in Module 2 -- how much profit is left from each euro of revenue. The second factor is asset turnover: how much revenue the company generates for each euro of assets it holds, a pure measure of efficiency, independent of how much margin each sale leaves. Businesses with low margins, like large retail, usually offset it with very high asset turnover -- they sell a large volume with little margin per unit, but turn their assets over quickly.\n\nThe third factor is financial leverage: how much total assets a company finances relative to its equity. The more debt a company uses to finance its assets instead of its own capital, the higher this factor -- and the greater the multiplying effect it has on ROE, even without any improvement in the business's margin or asset turnover. This is the specific mechanism behind the previous lesson's warning: two companies can reach the same ROE with identical margins and asset turnover, and still have very different leverage -- one generating that ROE with a genuinely efficient business, the other simply taking on more financial risk.
