Banquet Room Capacity and Pricing Calculator
Estimate how many guests your banquet room can accommodate based on seating style and square footage, then calculate total event pricing including venue rental, catering, and staffing.
Pricing Inputs
Formulas Used
Gross Room Area (sq ft) = Length (ft) × Width (ft)
Usable Area (sq ft) = Gross Area × (1 − Clearance% ÷ 100)
Maximum Capacity (guests) = floor( Usable Area ÷ Sq Ft per Person )
Venue Cost ($) = Venue Rate ($/hr) × Duration (hrs)
Catering Cost ($) = Catering Rate ($/person) × Guest Count
Staffing Cost ($) = Staff Count × Staff Rate ($/hr) × Duration (hrs)
Total Event Cost ($) = Venue Cost + Catering Cost + Staffing Cost + Miscellaneous
Cost per Guest ($) = Total Event Cost ÷ Guest Count
Sq Ft per Person by Layout: Theater 7 | Reception 6 | Banquet/Round 11 | Classroom 15 | Hollow Square 20 | Boardroom 25
Assumptions & References
- Square footage per person benchmarks follow guidelines from the National Fire Protection Association (NFPA 101 Life Safety Code) and industry-standard event planning references.
- Clearance percentage accounts for staging, dance floors, buffet tables, AV equipment, and emergency egress aisles; 20% is a common industry default.
- Banquet/Round Tables use 11 sq ft/person (midpoint of the 10–12 sq ft industry range for 60–72 inch round tables).
- Theater style (7 sq ft/person) assumes chairs only with no tables.
- Reception/Cocktail (6 sq ft/person) assumes standing guests with high-top tables.
- Staffing cost assumes all staff work the full event duration; overtime is not calculated.
- Catering cost is a flat per-person rate; gratuity, taxes, and service charges should be added separately.
- Local fire codes and occupancy permits may impose lower legal maximums — always verify with your venue's fire marshal certificate.
