    Average Profit Margin

    In order to compute the average value, you will need to add all profit margins and divide by the desired number. For instance, if a company wants to calculate the average profit margin of three products and the profit margins of each are 30, 35, and 40, simply add the three and divide it by 3.  The average profit margin therefore, in this case will be equal to 35.

    While this is for a particular item, the company can also obtain the value on an annual basis by calculating its overall cost and expenses. For instance, if a business has incurred costs in the region of $10,000 and $5000 in the first and second year respectively, and earned profits as 5000 (first) and 2000 (second), it can calculate average profit margin for the two years as follow:

    7000/ 15000 x 100 = 47 percent
