A $2,200 party isn't $2,200 of profit. Enter what the event brings in and what it costs you to run, and see what's left - in total, per guest, and against a normal night in that space. Every result shows its formula.

$1,069.20 ÷ 40 guests

This is contribution - revenue minus the costs the event itself adds. Rent, salaried managers, utilities, and other overhead you pay either way aren't included. Service charges and tips passed to staff aren't counted as revenue. It's arithmetic on your inputs, not accounting or tax advice.

A worked example

Forty guests spend $30 on food and $20 on drinks each, and you charge a $200 room fee:

  • Revenue: 40 × ($30 + $20) + $200 = $2,200
  • Food cost at 32%: $1,200 × 32% = $384
  • Beverage cost at 22%: $800 × 22% = $176
  • Extra labor: 4 staff × 6 h × $18 = $432
  • Other event costs: $75
  • Card processing at 2.9%: $2,200 × 2.9% = $63.80
  • Event profit: $2,200 − $1,130.80 = $1,069.20 (48.6%, $26.73 per guest)

Those percentages are placeholders to show the math - use your own food cost, pour cost, and wages. The useful comparison is the last input: if that room would have made $600 on a normal Saturday, the party is worth about $469 more than staying open to the public; if it would have made $1,300, you lost money by booking it.

What to do with the number

  • • Set minimums by day. Run it for a slow Tuesday and a busy Saturday. The gap is why many venues charge different minimums by day of week.
  • • Find your smallest worthwhile party. Lower the guest count until the event stops beating a normal night - that's the size where you need a room fee or a minimum.
  • • Price labor honestly. Setup and teardown hours count. Events that look great on revenue often lose their margin here.
  • • Leave gratuities out. A service charge you pass to staff isn't revenue to the house.

Turn the number into a quote

Use the result to set a room fee or a food and beverage minimum, then put it on a proposal the host can accept from their phone.
