How the newsletter revenue estimate works
LetterROI is a free newsletter ROI calculator for creators planning monetization. It projects three common income streams from your audience metrics:
- Programmatic ads — estimated from monthly opens and niche RPM benchmarks.
- Direct sponsorships — estimated with niche CPM and send cadence.
- Paid subscriptions — estimated from list size, typical conversion, and your monthly price.
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.
