Formula
Contribution per member = fee − benefit cost − (fee × processing rate) − other variable cost
Break-even members = fixed monthly costs ÷ contribution per member, rounded up
What the result means
The break-even member count is the smallest whole enrollment that covers the fixed costs entered. It does not guarantee positive cash flow if cancellations, refunds, taxes, or unentered expenses occur.
Use expected average benefit redemption cost, including labor and product. Revisit the assumptions when member behavior changes.
