Free Email List Growth Calculator
See how your email list will grow over the next months from new sign-ups, unsubscribes and bounces, and how many sign-ups you need to reach a subscriber goal.
How to use the list growth calculator
- Enter your current subscribers and average new sign-ups per month.
- Enter your monthly list loss, the share of subscribers lost to unsubscribes and bounces. 1% to 3% a month is common.
- Choose how many months to project, and add a goal if you have one.
Why lists stop growing
Every list loses some people each month. When the number you lose equals the number who join, growth stops. With 250 new sign-ups and a 2% monthly loss, that ceiling is 12,500 subscribers. To grow beyond it, you need more sign-ups or fewer people leaving.
Ways to get more sign-ups

Frequently Asked Questions
Is this list growth calculator free?
Yes. It is free with no sign-up, and your numbers stay in your browser.
What is a normal monthly unsubscribe rate?
It varies by audience and frequency, but losing around 1% to 3% of a list per month to unsubscribes and bounces is common.
How do I calculate list growth rate?
Subtract unsubscribes and bounces from new subscribers, divide by the list size at the start and multiply by 100.
Should I buy an email list to grow faster?
No. Bought lists have not opted in, which leads to spam complaints, poor delivery and can break data protection rules.
