Formula
Service staff = round up(guests ÷ guests per staff). Total staff = round up[(service staff + specialists) × (1 + buffer rate)].
What the result means
The main result is a planning estimate based on your inputs. Supporting figures show the intermediate values so you can identify which assumptions have the largest effect.
Planning tool only. Verify contractual, code, occupancy, pricing, tax, and safety requirements with the appropriate professional or authority.
Example calculation
For 150 guests at one service staff member per 25 guests, plus 4 specialists and a 10% buffer, the estimate is 11 staff.
Tips for better results
- Model servers, bartenders, kitchen crew, setup crew, and coordinators separately for detailed planning.
- Account for breaks, staggered shifts, setup, and cleanup time.
- Confirm staffing minimums and ratios with the venue and caterer.
