How much money does one email campaign really bring in? Email is a low-cost way to reach customers, but low cost does not always mean profit. The Email Marketing ROI Calculator follows your list from clicks to orders, then compares sales with cost.
You enter list size, rates, average order value, and campaign cost. The tool estimates orders, sales revenue, net profit, and ROI. It is built for store owners, newsletter publishers, and marketers planning or reviewing a send.

What the Calculator Does
The tool models a simple sales funnel. Each step shrinks the group until only buyers are left.
- Five inputs: subscribers sent to, click-through rate, site conversion rate, average order value, and campaign cost.
- Return on Investment (ROI): net profit as a percent of campaign cost.
- Total Campaign Sales Revenue: estimated orders times average order value.
- Total Conversions / Orders: estimated orders, with net profit shown in brackets.
- Calculate Email Campaign ROI button that refreshes the results.
Sample results appear when the page loads. Press the button after you edit any field.
How to Use It, Step by Step
- Enter how many people received the email in Subscribers Sent To.
- Enter Click-Through Rate (CTR, % of sent). This is clicks divided by emails sent, not by opens.
- Enter Site Conversion Rate (% of clicks), the share of clickers who buy.
- Enter your typical sale in Average Order Value ($ / sale).
- Add software, design, and copywriting costs in Total Email Tool & Copy Cost ($).
- Press Calculate Email Campaign ROI.
The Email ROI Formula
The tool multiplies your list by two rates to estimate orders. Then it prices those orders and compares them with cost.
Sent×CTR×Conversion Rate×Order Value=Revenue
- Clicks = subscribers sent × CTR ÷ 100.
- Orders = clicks × conversion rate ÷ 100.
- Revenue = orders × average order value.
- Net profit = revenue - campaign cost.
- ROI = net profit ÷ campaign cost × 100.
Worked Example
Devon sells coffee beans online. He emails a spring sale to 20,000 subscribers, and 3% of all recipients click through. Of those clickers, 2.5% buy at $60 each, and the campaign costs $300 for software and copy.
| Step | Calculation | Result |
|---|
| Clicks | 20,000 × 3% | 600 |
| Orders | 600 × 2.5% | 15 Orders |
| Revenue | 15 × $60 | $900.00 |
| Net profit | $900 - $300 | $600.00 net |
| ROI | $600 ÷ $300 × 100 | 200.00% |
The orders card reads 15 Orders ($600.00 net). Devon earned back his $300 plus $2 more for every dollar spent.
How to Read the Results
ROI above 0% means the email earned more than it cost. A negative ROI means revenue fell short of your cost.
Total Campaign Sales Revenue is gross sales before product costs, shipping, and refunds. Treat it as top-line revenue, not profit.
Total Conversions / Orders shows a whole estimate as a whole number, such as 15 Orders. A partial estimate keeps one decimal, such as 10.4 Orders, and revenue prices that exact figure. On a loss, the net amount turns red, such as 0.5 Orders (-$375.00 net).
Which Lever Moves Revenue Most
Every rate in the chain multiplies the others. Raising CTR from 3% to 4% lifts revenue by a third, with no extra subscribers. Better subject lines and clear buttons help clicks, while a fast checkout helps conversions.
Check your store's purchase rate with the conversion rate calculator. List growth costs money too. The cost per lead calculator shows what each new subscriber costs to sign up.
Keeping buyers matters as much as finding them. The customer retention rate calculator tracks how many customers stay. For a general gain versus cost check, use the return on investment calculator.
Comparing channels is smart budgeting. Run your paid social numbers through the social media ROI calculator to see which earns more. Browse more tools in the finance and business calculator hub.
Limitations and Assumptions
- CTR must be a share of all emails sent. If you enter a click-to-open rate, revenue will be overstated.
- Results update only when you press the button.
- A blank field, or a number outside its range, shows a message and N/A in all three cards.
- Subscribers must be 100 to 10,000,000, and both rates must be 0% to 100%.
- Average order value must be $1 to $10,000, and campaign cost $0 to $50,000.
- The tool has no open rate field, since CTR already counts clicks from the whole list.
- Revenue is gross sales. It ignores product costs, discounts, refunds, and unsubscribes.
FAQs About the Email Marketing ROI Calculator
What is the difference between CTR and click-to-open rate?
CTR divides clicks by all emails sent. Click-to-open rate divides clicks by opens only, so it is usually much higher.
How do I get CTR if my platform only shows click-to-open rate?
Multiply your click-to-open rate by your open rate. A 15% click-to-open rate with a 20% open rate gives a 3% CTR.
What should I include in campaign cost?
Include your email platform fee for the period, design, copywriting, and any paid images. Add staff time at a fair hourly rate for a truer picture.
Why does ROI show N/A when my cost is 0?
ROI divides profit by cost, and dividing by zero has no answer. The tool shows N/A with a short message, but revenue and orders still appear.
Can I use it to plan a future campaign?
Yes. Enter rates from past sends to estimate a new one. Try a few CTR and conversion values to see a low, middle, and high case.
Is the revenue figure the same as profit?
No. Revenue is total sales. The net figure subtracts only your email cost, not the cost of the products you sold.
