Creator income varies widely by audience quality, geography, niche, engagement, platform policies, advertiser demand, attribution, refunds, fees, and payment timing. Results are planning estimates only and do not promise income.

Scenario guidance

When to use this

Use this when estimating sponsor revenue for a newsletter campaign or media kit.

Example scenario

A newsletter publisher is pricing a monthly sponsorship package with four sponsored sends.

Inputs that usually matter most

  • Subscriber count, because it sets the audience base.
  • Open rate, because many sponsorships are priced against expected opens.
  • Sponsorship CPM and sends, which define the rate and campaign volume.

Common mistake to avoid

Do not price only from list size if sponsors care about audience quality, niche, clicks, placement, exclusivity, or past performance.

How to interpret the result

Use opens, revenue per send, and total revenue as estimates, then adjust for sponsor terms, makegoods, audience quality, and deliverables.

Results are estimates only and do not promise sponsorship deals, approval, rates, or creator income.

Sponsor space

Formula

Total sponsorship revenue = subscribers x open rate / 100 / 1,000 x CPM x sponsored sends

Opens per send are subscribers multiplied by open rate. Revenue per sponsored send divides opens by 1,000 and multiplies by sponsorship CPM.

Example newsletter sponsorship

25,000 subscribers at a 40% open rate produce 10,000 opens per send. At a $35 CPM across 4 sponsored sends, estimated revenue is $1,400.

Frequently Asked Questions

Is sponsorship CPM based on subscribers or opens?

This calculator applies CPM to estimated opens per send. Some sponsors may use subscribers, clicks, or flat rates instead.

Does this include agency or platform fees?

No. Subtract marketplace fees, agency fees, taxes, or production costs separately.
