The Email ROI formula
Email ROI = ((Revenue from Email − Email Cost) ÷ Email Cost) × 100
Email Cost includes platform fees and any production cost for that campaign or period.
Example
You spent $200 on an email campaign that generated $3,000 in revenue.
(($3,000 − $200) ÷ $200) × 100 = 1,400% email ROI
Worked example: $8,000 revenue, $500 cost
Email-attributed revenue was $8,000 and the programme cost $500.
- ($8,000 − $500) ÷ $500 × 100 = 1,500% ROI.
- Equivalent to $16 of revenue per $1 spent.
- Include platform fees, creative time and list costs in the cost figure, or ROI is overstated.
What to do next: Compare the figure with other channels using the same attribution window, and be cautious about revenue that would have happened without the email.
Why it's free
Email ROI often looks very high because costs are small and attribution is generous. A simple calculation helps you track the trend, but the result depends entirely on how revenue is attributed to email.

What is the formula behind the Email ROI Calculator?
Email ROI = ((Revenue from Email − Email Cost) ÷ Email Cost) × 100. Email Cost includes platform fees and any production cost for that campaign or period.
What costs should I include in email cost?
Include the email platform fee for the period, any design, copy or freelancer cost for the campaign, and tools used only for that send. Leaving costs out inflates the ROI.
Does a high email ROI mean the campaign caused the revenue?
Not necessarily. The result uses the revenue attributed to email, which depends on your attribution settings. Customers who would have bought anyway can inflate it, so compare with a holdout group when you can.
Why is email ROI so high compared with other channels?
Costs are usually low and attribution often credits email for sales that other channels influenced. Treat the number as a trend, not a precise comparison.
