Last month's retirement party for 85 guests taught me exactly why catering margins need careful calculation. You're working with fixed per-person pricing and must nail every cost estimate upfront. Calculate your margin by subtracting all expenses—food, labor, transport, materials—from your selling price per guest.
What is margin in catering?
Catering margin calculations differ completely from restaurant operations. You're locked into a fixed price per person and can't adjust costs mid-service. The margin represents what remains after covering every expense—and there's no room for error.
💡 Example:
Retirement dinner for 80 people at €45 per person:
- Revenue: 80 × €45 = €3,600
- Food costs: €1,440 (40%)
- Staff costs: €720 (20%)
- Other costs: €360 (10%)
Margin: €3,600 - €2,520 = €1,080 (30%)
All cost items in catering
You'll face expenses that don't exist in your regular restaurant. From analyzing actual purchasing data across different restaurant types, catering consistently shows higher variable costs due to off-site logistics.
- Food costs: ingredients, beverages, dessert
- Staff: chef, service, dishwashing on-site
- Transport: fuel, wear and tear, time
- Materials: dishes, linens, decoration (if rented)
- Preparation: extra hours in the kitchen
- Contingency: 5-10% buffer for no-shows or extra portions
Calculate food costs per person
Start with your menu and price every component. Don't skip the small stuff—bread, butter, and coffee add up fast across 80 covers.
💡 Example menu per person:
- Appetizer (soup): €2.80
- Main course (chicken with vegetables): €8.50
- Dessert (tiramisu): €3.20
- Bread and butter: €1.50
- Coffee with petit fours: €2.00
Food costs per person: €18.00
⚠️ Note:
Always add 5-10% extra food costs for waste and no-shows who still get fed. For 80 people you prep for 85.
Estimate staff costs
Catering demands more hands than usual since you're operating in unfamiliar territory. These ratios work consistently:
- Service: 1 person per 15-20 guests
- Kitchen on-site: 1 chef per 50-80 portions
- Dishwashing/cleanup: 1 person per 40-60 guests
- Hourly rate: €15-25 per hour depending on role
Include prep time and travel—your staff isn't just working the event hours.
Transport and material costs
These hidden costs destroy margins faster than you'd think. But they're predictable if you track them properly.
💡 Example transport costs:
- Fuel: €0.35 per km
- Vehicle wear and tear: €0.15 per km
- Driver: €20 per hour (there, on-site, back)
- Distance: 25 km one way = 50 km total
Transport costs: €25 + €60 driver = €85
Margin calculation formula
The formula's straightforward, but you can't afford to miss any expense category:
Margin per person = Selling price - (Food costs + Staff costs + Transport + Materials + Overhead)
Margin percentage = (Margin per person / Selling price) × 100
💡 Complete calculation:
80 people at €45 = €3,600 revenue
- Food: €18 × 85 portions = €1,530
- Staff: 4 people × 6 hours × €20 = €480
- Transport: €85
- Materials (rental): €200
- Overhead: €150
Total costs: €2,445
Margin: €3,600 - €2,445 = €1,155 (32%)
What is a healthy margin for catering?
Catering margins run higher than restaurant margins because you're taking on significantly more risk.
- Minimum: 25% margin (otherwise you're gambling)
- Healthy: 30-40% margin
- Excellent: 40%+ margin
⚠️ Note:
Catering offers no second chances. If you miscalculate and something goes sideways, you'll eat the loss. Always build in a safety buffer.
How do you calculate the margin on a retirement dinner? (step by step)
Calculate food costs per person
Add up all ingredients: appetizer, main course, dessert, bread, beverages. Add 5-10% extra for waste and no-shows who still get fed.
Calculate all other costs
Add up staff, transport, materials and overhead. Don't forget to include the preparation hours and transport time for your staff.
Subtract all costs from revenue
Revenue (number of people × price per person) minus all costs = your margin. Divide by revenue and × 100 for your margin percentage.
✨ Pro tip
Track your actual costs for the first 3 retirement dinners you cater, then compare against your estimates. Most caterers underestimate setup time by 30-45 minutes, which directly impacts labor costs.

Frequently asked questions
What minimum margin should I charge for catering?
Aim for 30% minimum, though 35-40% is safer territory. Catering carries more risk than restaurant service since you can't adjust pricing mid-event. You need that buffer for unexpected costs.
Should I include VAT in my margin calculation?
Never include VAT in margin calculations. If you're charging €45 including 9% VAT, your actual selling price is €41.28 per person. Always work with net figures.
How do I handle last-minute guest count changes?
Set a final headcount deadline 48 hours before the event. Charge for the confirmed number regardless of no-shows. Build 5-8% extra portions into your food costs automatically.
What if the venue has no proper kitchen facilities?
Factor in portable equipment rental and extended setup time. You'll need extra staff hours and potentially different menu options that don't require full kitchen prep on-site.
How do I price wine and beverages for retirement dinners?
Mark up beverages 200-300% from wholesale cost. For retirement events, budget 2-3 glasses of wine per person plus coffee service. Always confirm if the venue allows outside alcohol.
Should catering margins be higher than restaurant margins?
Absolutely. Restaurant margins typically run 8-15%, while catering should hit 30-40%. You're absorbing transport costs, setup risks, and working in unfamiliar environments.
How do I calculate overtime costs for evening events?
Evening and weekend events often trigger overtime rates. Budget €25-30 per hour for evening service staff versus €15-20 for regular hours. Factor this into events starting after 6 PM.
