1. Enter fixed monthly costs
Include expenses that do not materially change with member count, such as community software, moderation retainers, and recurring production tools.
2. Set the membership price
Use the amount charged to one member for the same monthly period as the fixed costs.
3. Add percentage fees
Combine payment processing and platform percentages that are deducted from gross membership payments.
4. Enter variable service cost
Include the incremental monthly cost of supporting one additional member.
5. Review the rounded threshold
The result rounds up because a fraction of a member cannot cover the remaining cost.
