Newsletter Valuation Calculator
Your email list is a cash-flowing asset, not just a follower count. Turn opens, CPM and premium revenue into a real valuation range — and the price you should charge sponsors.
How much is my email newsletter worth?
Value it on revenue, not subscriber count. Opens per send = subscribers × open rate, a sponsor slot pays (opens ÷ 1,000) × CPM, and monthly ad revenue is that times sponsored sends times your fill rate. Newsletters typically trade at roughly 2× to 4× annual revenue.
- Worked example (defaults on this page): 25,000 subscribers at a 40% open rate is 10,000 opens — $350 per slot at a $35 CPM.
- Eight sponsored sends a month at a 60% fill rate is $1,680 of monthly ad revenue; adding $1,500 of premium revenue gives $38,160 a year.
- That values the list between $76,320 and $152,640. Where you land in the range depends on revenue concentration, churn and how transferable the audience is.
- Open rate and fill rate matter more than list size. Doubling subscribers while halving the open rate leaves revenue exactly where it started.
Under the hood
The math, fully exposed
We price the audience off engaged opens, add premium revenue, then apply a media multiple:
Opens per send = subscribers × open rate
Revenue per ad slot = (opens ÷ 1,000) × CPM
Monthly ad revenue = sponsored sends × slot revenue × fill rate
Annual revenue = (ad revenue + premium revenue) × 12
Valuation ≈ 2× to 4× annual revenue
- Engagement is priced, not size: sponsors pay for opens, so a smaller, highly engaged list can out-earn (and outvalue) a larger, sleepy one.
- Premium revenue lifts the multiple: recurring paid subscriptions are stickier than sponsorships, so buyers pay more for a dollar of premium revenue than a dollar of ad revenue.
- A range, not a price: the actual multiple swings on growth, niche and founder dependence. Treat the midpoint as a starting point for negotiation, not a guaranteed check.

Answers
Frequently asked questions
How are newsletters and media businesses valued?
Most change hands at a multiple of revenue (or profit). For creator media, a common range is roughly 2× to 4× annual revenue, with the multiple driven by audience engagement, niche, growth rate, revenue diversity and how dependent the business is on the founder. A highly engaged, fast-growing list in a lucrative niche commands the top of the range; a stagnant, founder-dependent one sits at the bottom.
What is CPM and how should I price sponsorships?
CPM is "cost per mille" — the price per 1,000 opens (or impressions). Newsletter sponsor CPMs are unusually high, often $20–$50+, because the audience is engaged and targeted. Your fair slot price is simply (opens ÷ 1,000) × CPM. Pricing off opens rather than total subscribers rewards engagement and is what sponsors actually pay for.
What's a good newsletter open rate?
For engaged niche newsletters, 30–50% is healthy, and the best can exceed it. Open rate is the clearest proxy for audience quality, so it disproportionately affects both your CPM and your valuation. Two lists of the same size can be worth very different amounts purely on engagement.
How do I increase my newsletter's value?
Three levers: grow engaged subscribers (not just raw count), raise revenue per send (better fill rate and CPM), and add recurring premium revenue, which buyers prize for its stability and tends to earn a higher multiple. Reducing founder dependence — systems, a content team — also lifts the multiple at sale.
