Email List Value Calculator
Find what each email subscriber is worth per month and per year, and the total annual value of your list.
How it works
Value per subscriber per month = monthly email revenue ÷ subscribers · Annual value per subscriber = monthly value × 12 · Annual list value = monthly revenue × 12
A subscriber is worth whatever revenue your list generates divided by how many people are on it. Knowing the per-subscriber value tells you what a new sign-up is worth, so you can decide how much to spend acquiring one and what a bounce or unsubscribe actually costs. Per-subscriber value is the metric to watch over time: growing the list while it falls means you are adding people who do not buy.
Worked example
A list of 10,000 subscribers that drives $4,000 in sales a month is worth $0.40 per subscriber per month — about $4.80 a year each — and $48,000 in annual revenue across the whole list.
Frequently asked questions
What is a subscriber worth?
Divide the revenue your email drives in a month by your active subscriber count. Many consumer lists land somewhere around $0.10–$1.00 per subscriber per month, but it varies hugely by industry, price point and how often you sell.
Should I count total or active subscribers?
Use active subscribers — people who actually open or click. Counting long-dormant addresses inflates the list size and understates the true per-subscriber value, and can hurt deliverability too.
How do I raise email list value?
Improve segmentation and relevance, clean out dead addresses, test send frequency and offers, and grow the list with buyers rather than freebie-seekers. Rising per-subscriber value, not just a bigger list, is the goal.
