A 40-person birthday party at €45 per head might look profitable until you factor in transport, setup time, and buffet waste. Catering operates on a per-person pricing model rather than individual dish sales. Your margin comes from subtracting all event costs—food, labor, transport, and materials—from your per-person rate.
What does catering cost per person?
Catering flips your usual pricing model. Instead of selling individual dishes, you're pricing per guest and spreading all event costs across the headcount.
💡 Birthday party example:
40 people, 3-course menu for €45 per person (excl. VAT)
- Total revenue: 40 × €45 = €1,800
- Food costs: €18 per person = €720
- Staff: 2 people × 6 hours × €25 = €300
- Transport/materials: €150
Total costs: €1,170 | Margin: €630 (35%)
Calculate food cost for catering
The formula stays the same: food cost = ingredient costs / selling price per person × 100. But catering throws extra variables into the mix.
- Main courses: stick to precise portions per guest
- Side dishes: buffets demand more generous servings
- Desserts: don't forget coffee and tea if included
- Waste factor: buffets always generate leftovers
⚠️ Note:
Always plan 10-15% extra food for buffets. Guests expect variety and abundance. Build this buffer into your cost calculations.
Extra costs you can't ignore
Catering brings hidden costs that don't exist in your restaurant. Each one needs to flow through your per-person pricing.
- Transport: fuel costs plus vehicle wear
- Equipment: extra plates, glasses, serving utensils
- Setup labor: your team works beyond just cooking and serving
- Breakdown time: cleaning and packing takes hours
- Cancellation risk: food purchased but event canceled
💡 Transport cost example:
Venue 30 km away, round trip
- Kilometers: 60 km × €0.35 = €21
- Extra travel time: 2 hours × €25 = €50
- Material rental: €80
Extra costs: €151 for 40 people = €3.78 per person
Margin calculation step by step
Your margin represents what remains after covering every cost. Catering events typically carry more cost categories than regular restaurant service.
💡 Complete calculation:
Birthday party 40 people, €52 per person incl. VAT
- Selling price excl. VAT: €52 / 1.09 = €47.71
- Food costs per person: €18.50
- Staff: €300 / 40 = €7.50 per person
- Transport/materials: €150 / 40 = €3.75 per person
- Total costs: €29.75 per person
Margin: €47.71 - €29.75 = €17.96 per person (37.6%)
What's a good margin for catering?
Catering margins differ from restaurant operations. Higher risk and additional costs justify better margins than typical dine-in service.
- Target margin: 35-45% of total revenue
- Food costs: typically 35-45% (higher than restaurants due to buffet overages)
- Total expenses: including labor and transport usually hit 55-65%
⚠️ Note:
Always work with prices excluding VAT. Catering carries 9% VAT like restaurant service. A €50 inclusive price equals €45.87 for your margin calculations.
Track catering costs digitally
Multiple events with different menus make cost tracking complex. You'll lose sight of which parties actually generated profit.
Based on real restaurant P&L data, caterers using digital tracking see 15% better margins within six months. Tools like KitchenNmbrs calculate exact per-event costs, showing immediately whether each party hit your profit targets and where to adjust pricing next time.
How do you calculate the margin on a birthday party? (step by step)
Calculate your selling price per person excl. VAT
Divide your menu price by 1.09 to go from incl. VAT to excl. VAT. At €50 incl. VAT you get €45.87 excl. VAT per person.
Add up all food costs per person
Calculate what each dish costs per person. Don't forget side dishes, beverages and 10-15% extra for buffet surplus. Add everything up for the total food costs per person.
Calculate staff and extra costs per person
Divide all extra costs (staff, transport, materials) by the number of guests. This gives you the total costs per person.
Subtract all costs from your selling price
Selling price excl. VAT minus all costs per person = your margin per person. Multiply by number of guests for your total margin on the event.
✨ Pro tip
Track actual food waste after each 40-person event for 3 months. You'll spot patterns—maybe desserts always run short while sides get wasted—and can adjust portions to boost margins by 8-12% without disappointing guests.

Frequently asked questions
Should I include VAT in my margin calculation for catering?
Never calculate with VAT included. Catering uses 9% VAT like restaurant dining. A €50 inclusive price becomes €45.87 exclusive—use that figure for all margin calculations.
How much extra food should I plan for a buffet?
Plan 10-15% extra for buffet-style service. Guests expect abundant choices and full platters throughout the event. Plated service allows more precise portioning based on confirmed headcount.
What if fewer guests show up than expected?
Require final headcount confirmation 48 hours before the event. Build minimum guarantees into your contracts—typically 90% of the agreed number—to protect against last-minute cancellations.
How do I calculate transport costs per person?
Add mileage (distance × €0.35) plus driver time (hours × hourly wage) plus any equipment rental fees. Divide this total by guest count for your per-person transport charge.
