Event staffing calculator
Work out how many bar staff, waiting staff and security you need, based on guest count and service style.
How this is worked out
Bar staff are calculated at 1 per 50 guests. Waiting staff scale with service style: roughly 1 per 20 guests for buffets and 1 per 15 for plated table service, since plated meals need more hands per course. Security is recommended for outdoor, licensed, or larger events, at 1 per 100 guests with a minimum of one.
Worked example
For 100 guests with plated service: 2 bar staff, 7 waiting staff (100 ÷ 15, rounded up), and if outdoor or licensed, 1 security staff member as a baseline.
Frequently asked questions
Does this include kitchen or catering prep staff?
No — this covers front-of-house service only. Your caterer will quote kitchen staff separately based on the menu.
Do I need SIA-licensed security?
For licensed venues selling alcohol to the public, yes. For private events on private property, it's usually optional but still sensible for larger gatherings — check with your venue or local council.
