About this tool
What the Email Marketing ROI Calculator does
Email ROI compares the revenue your emails drive with the cost of the platform, design and copy. This calculator follows each email from sends to clicks to orders, and reports revenue per subscriber, revenue per thousand emails and overall return.
Formula
- Sends = subscribers × emails per month
- Clicks = sends × click rate
- Orders = clicks × conversion rate
- ROI = (revenue − cost) ÷ cost × 100
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Subscribers mailed | 10,000 |
| Emails per month | 4 |
| Click rate (of delivered) | 2.5% |
| Conversion rate (of clicks) | 3% |
| Average order value | $60.00 |
| Monthly email cost | $300 |
| Result | Value |
|---|---|
| Monthly email revenue | $1,800 |
| ROI | 500.0% |
| Orders | 30.0 |
| Clicks | 1,000 |
| Revenue per subscriber | $0.18 |
| Revenue per 1,000 emails | $45.00 |
How to read the result
Click rate is a better input than open rate. Mail privacy features now open emails automatically for many users, which inflates open rates without any real reading.
Revenue per 1,000 emails is the fairest way to compare campaigns of different sizes, and it shows whether sending more often adds revenue or just fatigue.

Questions about this tool
The things clients actually want to know — costs, timelines, ownership and what happens after launch.
Subtract the monthly cost of email from the revenue it generated, then divide by the cost. Revenue is sends × click rate × conversion rate × order value.
Privacy features in some mail apps register an open automatically, so open rates are unreliable. Clicks require a real action.
Monthly email revenue divided by the number of subscribers mailed. It tells you what each new subscriber is worth to the business.
