How the newsletter revenue estimate works

LetterROI is a free newsletter revenue calculator for creators planning monetization. It projects three common income streams from your audience metrics — a monthly range you can use for planning, not a full ROI that subtracts costs:

Figures are directional benchmarks, not guarantees. Sponsorship rates and paid conversion vary by niche, list quality, and offer. Use the calculator to compare scenarios, then validate with your own rates.

Newsletter monetization FAQ

How do newsletters make money?

Most newsletters earn from ads, sponsorships, and paid subscriptions. Some also use affiliate recommendations. LetterROI focuses on the three primary recurring streams so you can see a realistic monthly range before you invest in growth.

What is a good newsletter open rate for monetization?

Many healthy creator newsletters land between about 30% and 50% open rate. Higher opens mean more ad and sponsorship impressions, which increases estimated revenue.

Are LetterROI estimates guaranteed income?

No. The model uses directional niche benchmarks for RPM, sponsorship CPM, and paid conversion. Treat the output as planning math, not a promise.
