Why do so many caterers lose money on their biggest contracts? A healthy margin on a catering contract for 500 people sits between 30-45% of your selling price. Most caterers underprice because they forget hidden costs like transport, setup and no-show risk.
The cost structure of a large catering contract
Catering for 500 people brings different cost items than your restaurant. You need to account for:
- Food cost: 25-35% of your selling price
- Extra staff: 15-25% (you need more hands)
- Transport and materials: 3-8%
- Risk markup: 2-5% (for no-shows and unforeseen)
💡 Example:
Buffet for 500 people at €35 per person = €17,500 revenue
- Food cost (30%): €5,250
- Extra staff (20%): €3,500
- Transport/materials (5%): €875
- Risk markup (3%): €525
Total costs: €10,150 → Margin: 42%
Hidden costs that eat into your margin
Most caterers forget these cost items and lose money on large contracts. Something most kitchen managers discover too late is how quickly these overlooked expenses add up:
⚠️ Watch out:
Always budget for 5-10% more staff than you think you need. With 500 people something always goes wrong: someone doesn't show up, setup takes longer, or guests have special requests.
- Prep at home: Your kitchen's tied up for 1-2 days
- Round trip: Fuel, wear and tear, driver time
- Setup and breakdown: Minimum 4 hours of extra work
- Equipment rental: Warming plates, chafing dishes, tableware
- Insurance: Extended coverage for external locations
- No-show risk: You prep for 500, only 480 show up
Minimum margin by price point
Different price points need different margins to stay profitable:
💡 Example margins:
- Budget catering (€15-25 p.p.): minimum 35% margin
- Mid-range (€25-40 p.p.): minimum 40% margin
- Premium catering (€40+ p.p.): minimum 45% margin
The more expensive you are, the more buffer you need for unforeseen costs.
How do you calculate your break-even point?
For a contract of 500 people you need to know: what's the minimum I need to charge to break even?
Formula: Break-even price = (Food cost + Staff + Other costs) / Number of people
💡 Example break-even:
Total costs for 500 people:
- Ingredients: €6,000
- Extra staff: €2,500
- Transport/materials: €800
- Other costs: €700
Break-even: €10,000 / 500 = €20 per person
For 40% margin you charge: €20 / 0.60 = €33.33 per person
Risk factors with large contracts
The bigger the contract, the more can go wrong. Always build in a risk markup:
- Weather conditions: Outdoor events are riskier
- Last-minute changes: "Oh, 50 people are vegetarian"
- Location challenges: No kitchen, limited power
- Timing: Program delays = longer service
⚠️ Watch out:
Always ask for a deposit of at least 50% on contracts over €10,000. This covers your purchasing costs and protects you against cancellations.
Tools to keep track of your margin
With large contracts it's crucial that you know exactly what each dish costs. A small error in your cost price costs you hundreds of euros with 500 people.
A food cost calculator automatically calculates your cost price per person and shows right away if your quote's profitable. This prevents losing money on contracts that should actually make you rich.
How do you calculate a healthy margin on a catering contract? (step by step)
Calculate all ingredient costs per person
Add up all costs: main courses, side dishes, bread, sauces, drinks. Don't forget garnish and oil for the pans. Divide by the number of people to get your food cost per person.
Add up all extra costs
Calculate what you spend on extra staff, transport, equipment rental and risk markup. These costs are often 25-35% of your total revenue on large contracts.
Calculate your minimum selling price per person
Divide your total costs by the number of people to get your break-even point. For a healthy 40% margin divide this amount by 0.60. This is your minimum selling price per person.
✨ Pro tip
For catering contracts over €15,000, always build in a 3-hour buffer for setup and breakdown. Most venues take 90 minutes longer than promised, and this extra time costs you €200-400 in staff wages if you haven't planned for it.

Frequently asked questions
What's a realistic margin for catering 500 people?
A healthy margin sits between 35-45%, depending on your price point. Budget catering needs a minimum of 35%, premium catering can charge 45% or more.
What costs do I often forget on large catering contracts?
Most caterers forget transport, setup/breakdown time, risk markup for no-shows and the cost of extra staff. Together these can be 10-15% of your revenue.
How do I prevent losing money on large contracts?
Always calculate your break-even point beforehand and build in 5-10% risk markup. Ask for a 50% deposit and make sure you pass through all costs including transport and setup.
Do I need to calculate differently than regular restaurant service?
Yes, with catering you have higher staff costs for setup and transport but lower fixed costs. Your food cost can be slightly higher (30-35% vs 25-30% restaurant) because you have other savings.
Should I charge more for outdoor events versus indoor venues?
Absolutely. Outdoor events need a 3-5% higher margin due to weather risks, limited power access, and extra equipment needs. Always have a backup plan that's factored into your pricing.
How do I handle last-minute guest count changes?
Build flexibility into your contract with a final headcount deadline 72 hours before the event. Charge full price for increases after this deadline and only reduce billing by 50% for decreases.
What's the minimum deposit I should require for a 500-person event?
Require at least 50% deposit on contracts over €10,000, with the remainder due 48 hours before the event. This protects your ingredient costs and ensures serious commitment from the client.
