Newsletter Revenue Calculator Widget
A revenue model for newsletter writers. Subscribers, open rate, a sponsor CPM counted per 1,000 opens or per 1,000 sends, sponsored issues a month, paid conversion and price become monthly sponsorship income, net subscription income after the platform's cut, and the total.

How it works
Newsletters earn in two ways and this widget models both. Sponsorships are sold by CPM, but sponsors disagree on what is being counted: some pay per 1,000 emails sent, others only per 1,000 opens. The basis selector switches between them. With 10,000 subscribers and a 45% open rate, an opens-based CPM of 50 earns 4,500 / 1,000 x 50 = 225 per issue, or 900 across four sponsored sends a month. Paid subscriptions are the subscribers who convert to the paid tier times the monthly price: 2% of 10,000 is 200 readers at 8.00, 1,600 gross. Subscription platforms typically take a percentage, entered here as 10%, which leaves 1,440. The fee is applied only to subscription income because sponsors usually pay the writer directly. Total monthly revenue in this example is 2,340, about 28,080 a year. Every percentage is checked to sit between 0 and 100.
Calculation method
- Sponsored audience per issue = subscribers (per-send CPM) or subscribers x open rate (per-open CPM)
- Sponsorship per month = audience / 1,000 x CPM x sponsored sends per month
- Paid subscribers = subscribers x paid conversion %
- Net subscription income = paid subscribers x price x (1 - platform fee %)
- Total per month = sponsorship + net subscriptions; per year = x 12
Worked examples
Hybrid newsletter
Inputs: 10,000 subscribers; 45% opens; CPM 50 per 1,000 opens; 4 sponsored sends; 2% paid at 8.00; 10% fee
Result: 900 sponsorship + 1,440 subscriptions = 2,340 a month
Platform fee 160 a month; about 28,080 a year.
Per-send sponsorship only
Inputs: 10,000 subscribers; CPM 30 per 1,000 sends; 4 sends; no paid tier
Result: 1,200 a month
10 thousand sends x 30 x 4.

Limitations
- Ignores churn and list growth; the result is a snapshot for the subscriber count entered.
- Open rates measured by email tools are distorted by privacy features, so per-open income may be overstated or understated.
- Taxes such as VAT or GST on subscriptions are not separated out.
Where publishers use it
- A guide to starting a paid newsletter on a creator-economy blog
- A newsletter ad network's page explaining per-open versus per-send pricing
- A journalism school module on independent media business models
- A writer's coaching site helping clients decide between ads and a paywall
- An email-marketing agency comparing sponsorship income across list sizes
Questions
Should I sell sponsorships per send or per open?
Per-open pricing pays only for readers who opened the email, so its CPM is higher - at a 45% open rate, a 50 per-open CPM is the same money as 22.50 per send. Apple Mail Privacy Protection has inflated measured open rates since 2021, which makes some sponsors prefer per-send or per-click pricing.
What paid conversion rate is realistic?
It depends heavily on the writer and niche. The default of 2% is an example value only; use your own conversion once you have launched a paid tier, and model a few values to see how sensitive the total is.
Why is the platform fee applied only to subscriptions?
Subscription platforms take their cut from paid subscriptions they process. Sponsorship invoices are typically paid to the writer directly. If your platform also takes a cut of ad sales, reduce the CPM by that share.
Does it assume every sponsorship slot sells?
Yes. A newsletter with four weekly sends that sells two of them should enter 2 sponsored sends a month, or the sponsorship line will be overstated.
What about card processing fees?
Card processors charge a percentage plus a small fixed amount per payment. Add their approximate percentage to the platform fee field - for example 10% platform plus about 3% processing gives 13%.
