Formula
Expected visits/member = included visits × utilization
Contribution/member = monthly fee − processing fee − expected visits × variable cost
Break-even members = fixed monthly cost ÷ contribution/member, rounded up
What the result means
The main result is the smallest whole number of active members whose estimated monthly contribution covers the entered fixed program cost. It does not mean the whole business has broken even.
Actual utilization, cancellations, discounts, failed payments, and taxes can change program economics. Revisit the assumptions with observed member behavior.
