Email List Growth and Revenue Calculator
An email list is only worth what it earns. This calculator projects your list 12 months ahead and turns your click and sales numbers into revenue.
It also tells you what one subscriber is worth to you. That is the most you should ever pay to win one.
Email List Growth and Revenue Calculator
Project your list a year out and see what each subscriber is worth.
A simple model: each month the list loses the unsubscribe rate, then adds new signups, and every delivered email earns clicks times buyers times sale value. Real results vary by niche and offer.
How to Get Your Numbers
- Click rate: open your last five campaigns in your email tool and average the click rate.
- Clicks that buy: check sales or affiliate conversions from email traffic in your analytics.
- Average sale: use your average order value, or your average commission if you are an affiliate.

Why Your List Stops Growing
Every list loses people each month to unsubscribes and bounces. When new signups equal those losses, the list stops growing no matter how long you wait.
The calculator shows where that ceiling sits, and a stronger lead magnet or a second signup form raises it faster than sending more emails. Our guide on how to build an email list covers both.
Frequently Asked Questions
How much is an email subscriber worth?
It depends on your offer and audience. Divide 12 months of email revenue by your average list size to get your own figure, which is what this calculator does.
What is a good click rate for email?
It varies widely by industry and list. Use your own average from recent campaigns rather than a national figure, because your own numbers predict your results best.
Does sending more emails make more money?
Up to a point, since more emails mean more clicks but also more unsubscribes. Test one extra email a month and watch both numbers before going further.
