Tying the Ratios Together: The Du Pont Chart and Equation
Table 10-1 summarized MicroDrive’s ratios, and now Figure 10-2 shows how the re-
turn on equity is affected by asset turnover, the profit margin, and leverage. The chart
depicted in Figure 10-2 is called a modified Du Pont chartbecause that company’s
managers developed this approach for evaluating performance. Working from the
bottom up, the left-hand side of the chart develops the profit margin on sales.The var-
ious expense items are listed and then summed to obtain MicroDrive’s total cost,
which is subtracted from sales to obtain the company’s net income. When we divide
net income by sales, we find that 3.8 percent of each sales dollar is left over for stock-
holders. If the profit margin is low or trending down, one can examine the individual
expense items to identify and then correct problems.
The right-hand side of Figure 10-2 lists the various categories of assets, totals
them, and then divides sales by total assets to find the number of times MicroDrive
“turns its assets over” each year. The company’s total assets turnover ratio is 1.5 times.
The profit margin times the total assets turnover is called the Du Pont equation,
and it gives the rate of return on assets (ROA):
