Digital Marketing ROI Calculator (return on investment for campaigns)

What is digital marketing ROI?

Return on Investment (ROI) is a key metric that measures the profitability of marketing campaigns. It tells you how much money has been generated for every monetary unit invested. A positive ROI means the campaign is profitable, while a negative ROI indicates financial losses.

How is ROI calculated?

The traditional ROI calculation is straightforward. Subtract the investment from the revenue to get the net profit, then divide this result by the total investment. Finally, multiply by 100 to display it as a percentage.

Practical calculation example

To illustrate the concept, imagine you've launched a social media promotional campaign and obtained the following financial results:

• Total investment: $500 (direct ad spend + static design costs)
• Revenue generated: $2,000 (finalised sales attributed to the campaign)
• Net profit: $1,500 ($2,000 earned minus $500 initially invested)

Applying our formula: (($2,000 − $500) / $500) × 100 gives an exact ROI of 300%. This indicates very healthy profitability — for every dollar invested, your business generated $3 in net profit.
