ROMI Calculator (Return on Marketing Investment)

LAST UPDATE: July 4th, 2018


What is Return on Marketing Investment?

ROMI is a measurement of the effectiveness of a marketing campaign.

It takes a baseline level of business activity and measures it against the business activity from a time when a marketing campaign is running.

The final return is the extra profit above regular business activity less the cost of running the marketing campaign.


Baseline Profit = Baseline revenue – Baseline Cost of Goods Sold

Marketing Campaign Profit = Revenue – Cost of Goods Sold

Profit with Marketing Campaign Cost = Profit – Marketing Cost

Campaign Uplift = Profit with Marketing Cost – Baseline Profit

Return on Marketing Investment = (Campaign Uplift / Markting Cost) x 100%
