Calculating margins on external catering is like assembling a puzzle - you need all the pieces to see the complete picture. Most hospitality entrepreneurs forget the hidden costs and only calculate based on the caterer's purchase price. Here's how to calculate your real margin on outsourced F&B.
Why outsource external catering?
For large events or specialized dishes, external catering can be more cost-effective than handling everything in-house. You save on:
- Hiring extra staff
- Buying/renting special equipment
- Inventory risk with large quantities
- Time and stress of organizing yourself
But here's what changes: your margin structure shifts completely. You're not earning on ingredients anymore - you're earning on service and coordination expertise.
The hidden costs of external catering
The caterer's quoted price isn't your only expense. These additional costs stack up fast:
⚠️ Watch out:
Most entrepreneurs underestimate coordination time. Arranging external catering eats up 2-4 hours per event. Factor this into your cost calculations.
Direct additional costs:
- Transport to and from location
- Dishes and cutlery (if not included)
- Extra service staff
- Coordination and communication hours
- Insurance and liability coverage
Calculate your real cost price
Your total cost extends far beyond the caterer's invoice. From years of working in professional kitchens, I've seen operators miss these crucial elements:
💡 Example:
Event for 50 people, walking dinner:
- Caterer: €25 per person = €1,250
- Transport: €150
- Extra service staff: 2 people × 6 hours × €18 = €216
- Your coordination time: 3 hours × €35 = €105
- Contingency buffer (5%): €86
Total cost price: €1,807 (€36.14 per person)
Formula for total cost price per person:
(Caterer price + Transport + Staff + Coordination + Buffer) ÷ Number of people
From cost price to selling price
Now you can calculate realistic margins. External catering margins run significantly lower than in-house production:
- In-house production: 65-70% margin achievable
- External catering: 35-50% margin realistic
💡 Example continued:
Cost price: €36.14 per person
Target margin: 40%
Calculation: €36.14 ÷ (1 - 0.40) = €36.14 ÷ 0.60 = €60.23
Selling price: €60 per person (excl. VAT)
Factor in risk considerations
External catering brings different risks compared to in-house production:
- Quality risk: You're dependent on the caterer's standards
- Timing risk: Delivery delays can derail events
- No-show risk: Fewer guests, same fixed costs
- Cancellation risk: Last-minute caterer cancellations
Always build a 5-10% buffer into your cost calculations. This cushion covers unexpected expenses and protects your margins.
External catering doesn't always pay off
Sometimes in-house production makes more financial sense:
⚠️ Watch out:
For events under 20 people, fixed costs like transport and coordination become proportionally expensive. In-house production usually wins here.
Consider in-house production for:
- Small events (under 20 people)
- Dishes within your expertise
- Events at your own venue
- Times you have available staff capacity
Administration and record-keeping
Track these cost components for external catering:
- Caterer invoices (for VAT recovery)
- Transport receipts and mileage
- Extra staff hours worked
- Your own coordination time
Food cost calculators like KitchenNmbrs let you record these expenses per event, giving you accurate data for future pricing decisions.
How do you calculate the margin on external catering? (step by step)
Gather all cost items
Note the caterer's price per person, transport costs, extra staff costs, and your own coordination time. Don't forget a buffer of 5-10% for unforeseen costs.
Calculate the total cost price per person
Add up all costs and divide by the number of people. This is your real cost price per person, not just the caterer's price.
Determine your desired margin
For external catering, margins of 35-50% are realistic. Use the formula: Cost price / (1 - desired margin) = minimum selling price excl. VAT.
✨ Pro tip
Negotiate volume discounts with your top 2 caterers once you hit €15,000 in annual orders. A 5-8% discount significantly improves your margins on repeat business.

Frequently asked questions
What margin can I realistically charge on external catering?
External catering margins typically range from 35-50%, which is lower than in-house production. You're primarily earning on service coordination and event management rather than ingredient markup.
Should I include my coordination time in the cost calculation?
Absolutely. Coordinating external catering consumes 2-4 hours per event. Calculate this at €25-35 per hour minimum, or you're essentially working without compensation.
At what event size does external catering become cost-effective?
Generally for events of 50+ people, or for specialized cuisines you don't handle in-house. For smaller events under 20 people, fixed costs like transport and coordination often make in-house production more profitable.
How do I handle guest count fluctuations with external caterers?
Establish minimum and maximum guest numbers upfront with your caterer. Build a 5-10% no-show buffer into your quotes, or require advance payment from clients to cover guaranteed minimums.
What's the biggest cost mistake operators make with external catering?
Forgetting to price in coordination time and hidden logistics costs. Many operators only mark up the caterer's food cost and end up losing money on the administrative overhead.
How can I minimize quality risks when outsourcing catering?
Always request references and conduct tastings before committing. Establish clear timing and quality agreements in writing, and develop relationships with 2-3 reliable caterers for consistent collaboration.
