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

How we calculate this

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

What should I do with the result?

Compare a cautious case and a realistic case. Change one assumption at a time, then save both. These estimates support planning; they are not verified forecasts or funding decisions.
