What the result means
ROI is the profit on an investment as a share of what it cost. A 30% ROI means every 100 put in came back as 130. For a marketing campaign, enter the gross profit it brought in as the amount returned. Using revenue makes the campaign look better than it is.
The formula
ROI = (amount returned − amount invested) ÷ amount invested × 100
A worked example
A campaign costs 5,000.00 and brings back 6,500.00. That leaves a profit of 1,500.00, and 1,500.00 ÷ 5,000.00 × 100 gives an ROI of 30.00%.
