Marketing Campaign - Simple ROI Calculator

This tool will compute the simple return on investment (ROI) for a marketing campaign based on gross sales for the campaign, cost of goods sold and the total advertising costs.  It can be used for both B2C and B2B direct marketing and non direct response campaigns. 

After entering the gross sales projected from this campaign, enter either the gross margin % for the average sale, or enter the total cost of goods sold for the campaign.  Do not enter both.  After entering the GM% or the COG, enter the total advertising cost for the campaign.  You can double click in the boxes to enter the number directly or you can use the up/down arrows which appear when hovering over the box to adjust the numbers up or down.  If you enter the number manually, you can use the up/down arrow to adjust it after it's been entered.  Enter the gross margin percentage as a decimal (e.,g., 55% as .55).
