How to Calculate Newsletter Subscriber Value
The value per subscriber formula is: sends/month Γ open rate Γ CTR Γ conversion rate Γ average order value. This converts the full email funnel β delivery, open, click, purchase β into a per-subscriber revenue figure. Even a small list becomes very valuable when each subscriber is worth a few dollars per month.
Email marketing consistently delivers the highest ROI of any digital channel, often cited at $36β$42 return per $1 spent. A list of 5,000 subscribers each worth $0.50/month generates $2,500/month in potential revenue. Improving conversion rate from 1% to 2% doubles that number without adding a single subscriber.
This calculator measures revenue from direct sales only. Add sponsorship and paid subscription revenue separately for a complete picture of your list's value.
