Direct contribution is before rent and shared overhead. For membership gyms, allocate revenue consistently—do not count it again as incremental revenue.

Monthly classes = weekly classes × 52 ÷ 12. Attendance = monthly classes × capacity × utilization. Direct contribution = attendance × (revenue − variable cost) − monthly classes × coach cost.
