Return on investment
—
ROI (return on investment) tells you how much profit you made relative to what you spent, expressed as a percentage. It's the simplest way to judge whether a campaign, channel, or project actually paid off. Enter the revenue it generated and the amount you invested to get your ROI and net profit.
How to calculate roi
Formula
ROI = ((Revenue − Cost) ÷ Cost) × 100
Subtract your cost from the revenue that cost generated to get net profit, divide by the cost, and multiply by 100 for a percentage. A positive ROI means you earned more than you spent; 0% means you broke even; a negative ROI means the initiative lost money. For marketing specifically, be honest about which revenue is genuinely attributable to the spend.
Example
A campaign cost $2,000 and produced $5,000 in revenue.
ROI = ((5,000 − 2,000) ÷ 2,000) × 100 = 150%.
