1. Identify fixed membership costs
Enter monthly expenses that support the program regardless of small changes in member count, such as administration, software, or fixed campaign costs.
2. Enter the recurring fee
Use the monthly amount expected to be collected from one active member before any taxes or one-time enrollment charges not included in your model.
3. Estimate variable cost per member
Enter the average monthly cost of benefits, credits, rewards, consumables, or other items that rise as member volume rises.
4. Check member contribution
The calculator subtracts variable cost from the fee. A positive contribution is required before fixed costs can be recovered.
5. Plan above the threshold
Use the rounded-up break-even count as the first member level that covers modeled fixed cost, then add a margin of safety for churn, utilization variation, or payment failures if appropriate.
