This average gross margin calculator will help you to estimate the weighted average gross margin for a business. The margin represents the difference between the cost of producing or delivering a product and the price at which it sells.
Generally a business will have a number of product lines and know the margin (GM%) on each. Consequently to calculate the average GM% for the business it is necessary to weight each product GM% by its corresponding revenue.
Accordingly the Excel sheet, available for download below, helps a business calculate the weighted average gross margin by entering GM% and revenue for up to ten product lines.

In the example shown above the weighted average GM% for the 10 products the business sells is 59.4%
Additionally our tutorial on gross profit formula gives full details about how to calculate the GM% for a business.
