How many staff do you need for your event?
For a 150-guest company holiday party with a buffet and a full bar, you need about 15 people: 6 servers, 3 bartenders, 1 barback, 2 catering attendants, 2 coat check and 1 captain. In Chicago, agencies typically bill about $3,700 to $4,880 for that team. The calculator above works out your own numbers from five questions.
How many bartenders do you need per 100 guests?
Plan on 2 bartenders for 100 guests at a full bar, 2 at a beer and wine bar and 3 if you serve made-to-order cocktails. The more drinks you mix by hand, the fewer guests one bartender can keep up with.
- Beer and wine
1 bartender per 75 guests. Pours are quick and need no mixing. FAUR Event Staffing gives 75 to 100, Liveforce gives 75.
- Full bar
1 bartender per 50 guests. This is the most common figure. Liveforce and Qwick both use 50, and Pebb gives 50 to 75.
- Craft cocktails
1 bartender per 35 guests. Cocktail-led menus run from 1 per 35 to 1 per 50 across the sources we checked, so we use the tight end.
- Upscale service
We tighten each of those by about 20% when you choose upscale, so guests wait less. At 150 guests a full bar needs 3 bartenders at standard service and 4 at upscale.
Add a barback once you have two bartenders, then one more for every two bartenders. A barback stocks ice, glassware and bottles so the bartenders can keep pouring. Qwick suggests 1 barback per 2 bartenders, while Liveforce uses 1 per 3, so this is a judgment call at busy events.
How many servers for 100, 150 or 200 guests?
For 100 guests you need 8 servers at a plated dinner or 4 at a buffet. Plated service needs the most servers because each person is served at their seat. At 200 guests that is 15 servers for plated and 8 for a buffet.
| Service style | Guests per server | 100 guests | 150 guests | 200 guests |
|---|---|---|---|---|
| Plated dinner | 1 per 14 (upscale 1 per 11) | 8 (10) | 11 (14) | 15 (19) |
| Buffet | 1 per 25 (upscale 1 per 20) | 4 (5) | 6 (8) | 8 (10) |
| Food stations | 1 per 25 (upscale 1 per 20) | 4 (5) | 6 (8) | 8 (10) |
| Passed appetizers | 1 per 25 (upscale 1 per 20) | 4 (5) | 6 (8) | 8 (10) |
Why do published staffing ratios disagree?
Because nobody sets a standard. Each caterer and agency publishes the ratio that fits how it works, and some count a separate busser while others do not. We list what each source says and show you the ratio we used in every result.
- Plated dinner
Liveforce 1 per 14 (premium 1 per 11). Pebb 1 per 10 to 12. Turnozo 1 per 20. Qwick and Zarla 1 per 25, with bussers counted on top. FAUR 1 per 5 to 8. We use 1 per 14, and 1 per 11 for upscale.
- Buffet
Liveforce 1 per 25 (premium 1 per 20). Pebb 1 per 20 to 25. Turnozo 1 per 30. Zarla 1 per 40. FAUR 1 per 35 to 50. We use 1 per 25, and 1 per 20 for upscale.
- Passed appetizers
Pebb 1 per 20 to 30. Turnozo and Qwick 1 per 25. FAUR 1 per 35 to 50, plus 1 or 2 for tray prep. We use 1 per 25, and 1 per 20 for upscale.
- Food stations
No source gives a ratio for stations alone, so we treat them like a buffet. Ask your caterer how many stations they plan to staff.
What does event staff cost per hour?
Agencies typically bill $47 to $79.50 an hour for bar staff and $30.50 to $49 an hour for general event staff in the 20 cities we checked, and the 8 big ones are below. This is the bill rate, which covers the worker's pay plus the agency's payroll tax, insurance and fee. It is not what the worker takes home.
| City | Bar staff | General labor and registration | Captain or supervisor |
|---|---|---|---|
| New York City | $63.5 to $79.5 | $43 to $49 | $53 to $59 |
| San Francisco | $63.5 to $79.5 | $43 to $49 | $53 to $59 |
| Los Angeles | $58.5 to $74.5 | $38 to $44 | $48 to $54 |
| Seattle | $58 to $74 | $37.5 to $43.5 | $47.5 to $53.5 |
| Chicago | $50.5 to $70.5 | $34 to $40 | $44 to $50 |
| Miami | $50 to $70 | $33.5 to $39.5 | $43.5 to $49.5 |
| Atlanta | $48.5 to $68.5 | $32 to $38 | $42 to $48 |
| Houston | $47 to $67 | $30.5 to $36.5 | $40.5 to $46.5 |
TempGuru does not list servers separately, so we price them at 83% of the bar range. That ratio comes from one Dallas rate card that lists bartenders at $45 to $55 and servers at $38 to $45. Treat the server line as the least certain part of your estimate. Real quotes also add food, drinks, travel and sometimes a holiday rate.
How many hours will you pay for?
More than the length of your party. A 4-hour event is usually billed as 6 paid hours for most roles: the 4 hours plus about 2 for setup and pack-down. Liveforce adds 2 hours to every shift, and agencies such as TempGuru and FAUR bill at least 4 hours per person even for a shorter call.
Coat check starts an hour before guests arrive and stays an hour after, based on Columbia University's coat check staffing guidelines. A registration desk is busy for the first hour or two. In both cases the 4-hour minimum is what you pay.
When do you need a captain or supervisor?
Add one once your team passes about 10 people. A captain runs the floor, handles breaks and is the one person the caterer and the venue talk to. FAUR says to add supervisors at 10 or more staff. Liveforce uses one team leader per 10 staff. Qwick suggests a captain for events of 100 guests or more.
We add 1 captain per 10 other staff, rounded down. Captains cost more per hour than servers: $40.50 to $59 an hour in the cities above.
How many people do you need for coat check, registration and security?
- Coat check
1 attendant per 100 guests in cold months and 1 per 150 in warm months, from Columbia University's facilities guidelines. Cold months here means November to March.
- Registration desk
1 person per 100 guests. Liveforce puts a manual list at about 75 guests an hour and a QR scanner at about 150, and TickPick says a trained scanner handles 6 to 10 people a minute.
- Event security
1 guard per 150 guests with no alcohol, 1 per 100 with a bar and 1 per 75 at a public event, with at least 2 guards once you reach 100 guests. TickPick gives 1 per 50 to 100, Ticket Fairy 1 per 75 to 100 for alcohol-led events.
- Setup and teardown crew
2 people per 100 guests, at least 2. Zarla suggests 2 crew per 100 chairs.
This is planning guidance, not legal advice. Whether you need licensed guards depends on your state, your venue and your insurer, so ask them before you book.
How far ahead should you book staff for a December party?
Book this week. Table Side Gourmet, a Scottsdale caterer, says companies lock in December dates by October, that Fridays and Saturdays fill first, and that late planners are often left with weekdays or off-peak hours. Its general advice for a corporate holiday party is to start 4 to 6 months ahead. If you are booking in mid-November, ask for a weekday, or an earlier start, and give your headcount when you first ask.
150-guest company holiday party in Chicago
- Bartenders: 150 guests ÷ 50 = 3.0, so 3 bartenders for a full bar. 3 bartenders ÷ 2, rounded down, gives 1 barback.
- Servers: 150 guests ÷ 25 = 6 servers for a buffet. 6 servers ÷ 3 = 2 catering attendants.
- Coat check: 150 guests ÷ 100 in cold months, rounded up, gives 2.
- Captain: 14 other staff ÷ 10, rounded down, gives 1. The team is 15 people.
- Hours: 4-hour event plus 2 hours of setup and pack-down is 6 paid hours each, or 90 paid staff hours.
- Cost: Chicago bar staff bill $50.50 to $70.50 an hour, servers about $42 to $59, general labor $34 to $40 and a captain $44 to $50. Total $3,700 to $4,880, about $4,290 in the middle.
- Compare: A beer and wine bar needs 14 people and costs about $360 less. Ending one hour earlier saves 15 paid staff hours, about $710.
How many staff for 50, 100, 150, 200 or 300 guests?
For a buffet with a full bar, standard service, a 4-hour event and coat check on, you need 5 people for 50 guests, 11 for 100, 15 for 150, 20 for 200 and 30 for 300. This table comes from the same calculation as the tool above, so the numbers match.
| Guests | Bartenders and barbacks | Servers and attendants | Coat check and captain | Total team | Typical Chicago bill |
|---|---|---|---|---|---|
| 50 | 1 | 3 | 1 | 5 | $1,210 to $1,610 |
| 100 | 3 | 6 | 2 | 11 | $2,690 to $3,510 |
| 150 | 4 | 8 | 3 | 15 | $3,700 to $4,880 |
| 200 | 6 | 11 | 3 | 20 | $4,920 to $6,480 |
| 300 | 9 | 16 | 5 | 30 | $7,400 to $9,750 |
