1. Enter fixed monthly costs
Include costs that do not change directly with subscriber count, such as moderation tools, community software, or recurring production overhead.
2. Set the monthly membership price
Use the amount charged to one paying subscriber before platform fees.
3. Add the platform fee rate
Enter the percentage deducted from subscription revenue by the membership or payment platform.
4. Include per-subscriber cost
Add fulfillment, benefits, support, or other costs that rise with each active member.
5. Review the threshold
The main result rounds up to a whole subscriber because a fraction of a subscriber cannot cover the remaining cost.
