Email Marketing ROI Calculator
Plan an email campaign with your own rates: from emails sent to opens, clicks and orders, and what is left after the campaign cost. Add your margin to see contribution rather than revenue.
Would this email campaign pay for itself?
Clicks ÷ opens
Orders ÷ clicks
Sending, design and your time
Without it, results are on revenue
Nothing is saved or sent anywhere.

The formula
Orders = emails × open rate × clicks per open × clickers who buyNet = orders × order value × margin − campaign costWorked example
10,000 emails at a 40% open rate and 10% clicks per open give 400 clicks; at 5% buying, that is 20 orders. At $80 each that is $1,600 of revenue, or $800 of contribution at a 50% margin. After a $500 cost, $300 is left — a 60% return on contribution.
What the result means — and what it does not
- It is a scenario from assumed rates, not measured attribution.
- Some of the orders might have happened without the email.
Common questions
Can I use this for a campaign I already sent?
You can, but measured numbers are better: take the sales your email platform or store attributes to the campaign and compare their contribution with what the campaign cost.
Why are open rates unreliable?
Some email apps load images automatically, which counts as an open whether or not anyone read the email. Clicks and orders are more trustworthy signals.
What should the campaign cost include?
Your email platform fee for the send, any design or copywriting, and a fair value for your own time.
