Most caterers make the same costly mistake: they price external events like they're serving from their own kitchen. But external venues bring hidden costs that can turn a profitable event into a money-losing nightmare. Here's how to calculate margins that actually protect your bottom line.
All cost items for external catering
External catering involves way more than just ingredients. You'll need to account for:
- Food cost: ingredients per person
- Labor costs: chefs, service staff, travel time
- Transport costs: fuel, wear and tear, time
- Material costs: dishes, linens, warming equipment
- Venue costs: kitchen rental, electricity consumption
- Unexpected costs: buffer for overruns, extra staff
💡 Example cost breakdown:
Buffet for 50 people, external venue:
- Food cost: €12 per person = €600
- Staff (2 people, 8 hours): €320
- Transport there and back: €80
- Material rental: €150
- Venue contribution: €100
Total costs: €1,250
Calculate your minimum selling price
For a healthy margin in catering you typically work with 60-70% total costs (food + labor + other). This means you retain a minimum of 30-40% margin.
Formula:
Minimum selling price = Total costs / 0.65
💡 Example calculation:
Total costs: €1,250
Minimum selling price: €1,250 / 0.65 = €1,923
Per person: €1,923 / 50 = €38.46
⚠️ Note:
Always calculate with 9% VAT on catering. Your selling price must therefore be multiplied by 1.09 for the price including VAT.
Extra costs from working with external venues
External venues (event halls, hotels, conference centers) bring specific costs that'll eat into your margins:
- Kitchen rental: often €50-150 per event
- Electricity consumption: usually a fixed rate €25-75
- Waste disposal: €20-50 depending on quantity
- Parking costs: for your transport van
- Venue commission: some venues charge 5-15% of your revenue
This is a pattern we see repeatedly in restaurant financials - caterers underestimate venue-related expenses and wonder why their margins disappear. And those commission fees? They're calculated on your total revenue, not your profit.
💡 Example with venue costs:
Same event as above, but now with venue costs:
- Base costs: €1,250
- Kitchen rental: €100
- Electricity: €50
- Venue commission (10%): €200
New total: €1,600
Minimum selling price: €1,600 / 0.65 = €2,462
Per person: €49.24
Account for risk factors
External catering carries more risks than your own kitchen. Always build in a buffer:
- No-shows: you prepped for 50 people, only 45 show up
- Event overruns: staff needs to stay longer
- Transport problems: traffic, broken cooling
- Material damage: dishes break during transport
A common buffer is 5-10% of your total costs.
Using tools for catering calculations
Tracking all these costs gets complicated, especially with varying venues and group sizes. Tools like KitchenNmbrs can help you:
- Scale standard recipes to number of people
- Save fixed cost items (transport, materials) per event type
- Quickly create quotes with realistic margins
- Track which events are most profitable
How do you calculate the margin on external catering? (step by step)
Calculate your food cost per person
Add up all ingredient costs and divide by number of people. Don't forget to include garnishes, sauces and drinks.
Add up all extra costs
Calculate labor, transport, materials, venue rental and any commissions together. Make a checklist so you don't forget anything.
Calculate minimum selling price
Divide your total costs by 0.65 for 35% margin. Add 5-10% buffer for unexpected costs.
Check if your price is market-competitive
Compare your price per person with other caterers in your region. Too high? Look for ways to save without compromising quality.

Frequently asked questions
What margin is normal for external catering?
A healthy margin is between 30-40% of your selling price. This means your total costs should be a maximum of 60-70% of your selling price.
Do I need to calculate VAT on the venue rental?
No, the venue rental is a cost item for you. You calculate 9% VAT on your own selling price to the customer.
How do I calculate transport costs per event?
Calculate fuel, wear and tear on your van (€0.30-0.50 per km) plus driver time. For local events many caterers charge a fixed rate of €50-100.
What if the venue charges a commission on my revenue?
Add the commission to your costs before you calculate your selling price. With 10% commission your €2000 quote actually becomes €2200 including commission.
Should I charge differently for weekend versus weekday events?
Yes, weekend events typically cost 15-25% more due to higher staff wages and venue premiums. Factor these into your labor calculations from the start.
How do I prevent losing money on catering?
Always make a detailed cost calculation beforehand. Add up all small cost items and calculate a 5-10% buffer. Better to miss a quote than to lose money.
