What this calculator tells you

See how much revenue your newsletter generates per 1,000 readers

Use this calculator to combine your newsletter income streams and measure how efficiently your audience is monetized.

A newsletter can earn money from more than sponsorships. Paid subscriptions, affiliate links, products, courses, and other offers can all contribute to total newsletter revenue.

This calculator shows revenue per 1,000 active subscribers and per 1,000 expected opens, plus net profit after newsletter costs.

Good to know

Use subscribers, revenue, and costs from the same period. If you enter one month of newsletter revenue, also use the subscriber count and costs from that month.

How it works

How newsletter RPM is calculated

The calculator turns several newsletter revenue streams into simple audience-based metrics.

1

Enter your newsletter audience

Add active subscribers and average open rate so the calculator can estimate opens.

2

Add newsletter revenue

Combine sponsorship, paid subscription, affiliate, product, and other newsletter revenue.

3

Calculate RPM

Total revenue is divided by subscribers and expected opens, then multiplied by 1,000.

4

Subtract newsletter costs

If you add production, software, and growth costs, the calculator also shows net profit and net RPM.

FAQ

Newsletter RPM questions

Simple answers to common questions about newsletter revenue per 1,000 readers.

What does newsletter RPM mean?

In this calculator, RPM means revenue per 1,000 subscribers or per 1,000 opens, depending on the result you are looking at.

Is newsletter RPM the same as sponsorship CPM?

No. Sponsorship CPM measures one sponsor deal against audience delivery. Newsletter RPM can include all newsletter revenue streams together.

Should I include product sales from my newsletter?

Yes if those sales are meaningfully driven by the newsletter and relate to the same period you are analyzing.

Why calculate both subscriber RPM and open RPM?

Subscriber RPM measures monetization across the list, while open RPM adjusts for the portion of subscribers who are actually expected to open an issue.

Should newsletter software costs be included?

Yes if you want to measure net newsletter economics rather than gross revenue alone.
