This is an estimate based on public benchmarks, not a promise or a forecast of earnings.
Assumptions, in plain text
- Comments per month = uploads per month × average comments per video. Comments on older videos are not counted, so the real number is usually higher.
- About 1% of subscribers comment regularly. That is a conservative read of creator-engagement benchmarks; some channels are well above it.
- A fan who never gets a reply is treated as a fan you don't convert. The value per active fan ($0.20–$0.50/month) comes from Patreon's “Value of a Fan” range and covers memberships, merch and direct support — not ad revenue.
- Replying does not directly buy revenue. The figure is a rough ceiling on what the relationship is worth, not money you are guaranteed to earn.
- No data is sent anywhere. Everything is calculated in your browser.
