Large-scale costing is like switching from a bicycle to a freight truck – the mechanics change completely. You can't just multiply your regular portion costs by 100. Bulk production brings savings on ingredients but adds layers of complexity in labor, logistics, and risk management.
Why large volumes are different
Catering and events aren't about cooking 10 portions – you're handling 100, 200, or more. This shift transforms your entire cost structure:
- Bulk purchasing power: Ingredients cost less per unit
- Additional workforce needs: Prep, transport, and setup teams
- No-show exposure: Overproduction from last-minute cancellations
- Distribution expenses: Containers, transport, and setup equipment
💡 Example:
Lasagna for 150 people at a corporate event:
- Ingredients: €4.20 per person
- Packaging (warming trays): €0.80 per person
- Extra labor (prep + transport): €1.50 per person
- No-show buffer (5%): €0.32 per person
Real cost price: €6.82 per person
Ingredient costs for large volumes
Bulk orders deliver savings, but not across every ingredient. Calculate your material costs with precision:
- Primary ingredients: Typically 10-20% cheaper with 10+ kilo orders
- Seasonings and aromatics: Minimal usage means prices stay flat
- Perishable items: Can cost more due to spoilage risk
⚠️ Watch out:
Don't assume automatic discounts. Verify your supplier's actual volume pricing for your specific quantities first.
Including labor costs
High-volume production demands significant additional workforce – the kind of thing you only learn after closing your first month at a loss:
- Extended prep time: Usually requires advance preparation
- Delivery and installation: Travel time plus setup
- Event service: If your quote includes on-site staff
- Cleanup operations: Breakdown takes considerable time
Budget between €1.00 to €2.50 per person for additional labor in catering operations, scaling with complexity.
💡 Example labor costs:
Event for 100 people, 8 hours of work (prep + event + breakdown):
- Chef wages: €25/hour × 8 hours = €200
- Assistant: €18/hour × 6 hours = €108
- Travel time and fuel: €50
Total: €358 ÷ 100 people = €3.58 per person
Building in a no-show buffer
Events consistently have fewer attendees than promised. Build a 5-10% cushion into your costs:
- You prep for 100 guests, 92 actually attend
- The overage gets factored into your base pricing
- This prevents absences from destroying your profit margins
Packaging and transport
These expenses slip under the radar but accumulate quickly:
- Heat-retention containers: €0.50 to €1.50 per person
- Disposable serviceware: €0.30 to €0.80 per person
- Vehicle expenses: Fuel, maintenance, driver time
- Temperature control equipment: Equipment depreciation per event
💡 Complete example:
Full cost price buffet for 120 people:
- Ingredients (with bulk pricing): €5.80 per person
- Extra labor: €2.20 per person
- Packaging and dishes: €1.10 per person
- No-show buffer (7%): €0.64 per person
- Transport and logistics: €0.45 per person
Total cost price: €10.19 per person
Profit margin for catering
Catering events typically support higher margins than restaurant service:
- Standard catering food cost: 35-45% (elevated due to additional expenses)
- Complete cost structure: 55-65% of final price
- Net profit margin: 35-45%
⚠️ Watch out:
Factor in every expense before setting prices. Underpriced catering can devastate your monthly profits due to the massive volumes involved.
Track digitally
Manual calculations become unreliable with large volumes. Digital systems help you:
- Auto-calculate ingredient costs for any headcount
- Model different scenarios (90, 100, 110 people)
- Monitor all additional expenses per event
- Identify your most profitable events
Calculate cost price for large volumes (step by step)
Calculate basic ingredient costs per person
Make a list of all ingredients for your dish. Check with your supplier if you get a discount for large orders. Divide the total ingredient costs by the number of people.
Add up all extra costs
Calculate: extra labor hours × hourly wage, packaging costs, transport costs, and any equipment rental. Divide this by the number of people for the extra costs per person.
Build in no-show buffer
Multiply your total cost price per person by 1.05 to 1.10 (5-10% buffer). This compensates for people who don't show up but you've prepared for anyway.
Determine your selling price
Divide your total cost price by your desired cost price percentage. At 40% cost price: cost price ÷ 0.40. Don't forget to add 9% VAT for the final price.
✨ Pro tip
Track your first 8 catering events in a spreadsheet, comparing actual versus projected costs. You'll spot exactly where your estimates run high or low, letting you fine-tune pricing within 60 days.

Frequently asked questions
Should I include VAT in my catering cost price?
No, always calculate excluding VAT. Catering carries 9% VAT, identical to restaurant service. Add VAT at the final step for customer pricing.
How much no-show buffer should I build in?
Average 5-10%, varying by event type. Corporate functions see fewer no-shows (5%) than private celebrations (10%). Track your historical patterns for accuracy.
Do I always get a discount for large purchases?
Not automatically. Many suppliers offer discounts starting at 10-15 kilos, but verify beforehand. Fresh products sometimes cost more due to increased spoilage risk.
How do I pass on transport costs?
Calculate €0.30 per kilometer round-trip, plus loading/unloading time (€20-25 hourly). Divide by guest count – large events make this minimal per person.
Can I use the same food cost as in my restaurant?
No, catering involves higher total costs from labor, transport, and packaging. Budget 35-45% total cost price versus the 28-35% standard for restaurants.
What if more people show up than expected?
Include overage terms in your contract. Example: 'fixed rate up to 100 people, €X per additional guest above that.' This prevents unexpected shortfalls.
