The process of calculating ROI is a straightforward one. It can be determined using one of these two methods.
You will take the growth in sales from the business or product line and subtract the marketing expenses and split it up by marketing expenses.
ROI = (Sales Growth – Marketing Costs) / Marketing Costs
(1) Margin = operatin income/ net sales
= 280,000/1,400,000
= 20%
(2) turonver = sales/ Average total assets
= 1,400,000/875,000
= 1.6
(3) ROI =
1.6*20 = 32%
(4) Margin = 480,[email protected]% – 336,000 =
$48,000
= 48,000/480,000 = 10%
(5) Turnover = 480,000/300,000 = 1.6
(6)
ROI = 10*1.6
= 16%
(7) Margin = (280,000+48,000)/ (1,400,000
+480,000)
= 17.45%
(8) Turnover = 1,880,000/1,175,000 = 1.6
(9)
Roi =
1.6*17.45 = 27.92%
