About this tool
What the Event Staffing Calculator does
Staffing levels follow service style: plated dinners need more servers per guest than buffets, and bar staffing depends on how many guests are drinking at once. Common planning ratios turn your guest count into staff numbers and a labour budget.
It also works as a catering staffing calculator.
Formula
- Servers = guests ÷ guests per server (rounded up)
- Bartenders = guests ÷ guests per bartender
- Cost = staff × hours × hourly cost
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Guests | 150 |
| Service style | Plated dinner (1 per 12) |
| Guests per bartender | 75 |
| Support staff (captain, runners, kitchen) | 3 |
| Hours per staff member including setup | 7 |
| Cost per staff hour | $28.00 |
| Result | Value |
|---|---|
| Total staff | 18 |
| Staff cost | $3,528 |
| Servers | 13 |
| Bartenders | 2 |
| Staff cost per guest | $23.52 |
How to read the result
Add bartenders for a busy opening rush or a full open bar; one bartender per 50 guests keeps queues short.
Book staff for setup and breakdown time, not just the event hours.
