A catering company recently lost €800 on what seemed like a profitable 60-person corporate lunch because they forgot transport costs and staff overtime. Most caterers estimate buffet pricing but miss hidden expenses like service, transport and no-shows. Here's how to calculate a profitable per-person price that actually covers everything.
All costs of a lunch buffet
A lunch buffet involves way more expenses than just the food. Miss even one and your profits vanish quickly.
- Ingredient costs: every product going on the buffet
- On-site staff: setup, refilling, breakdown
- Transport: fuel, time, vehicle wear
- Materials: chafing dishes, warming plates, serving utensils
- No-show buffer: you'll prep for more people than actually arrive
⚠️ Note:
Always calculate with your selling price excluding VAT (9% for catering). Otherwise your margin looks higher than it actually is.
Step 1: Calculate your ingredient costs per person
Add up every product going on the buffet. Calculate per person, not per platter - it's more accurate.
💡 Example buffet for 50 people:
Standard business lunch buffet:
- Rolls and fillings: €4.50 per person
- Salad and vegetables: €2.80 per person
- Warm appetizers: €3.20 per person
- Fruit and dessert: €1.50 per person
Total ingredient costs: €12.00 per person
Don't forget cutting waste and spoilage. Buffets typically lose 10-15% extra due to over-preparation and leftovers that can't be reused.
Step 2: Add up your operational costs
Beyond ingredients, these expenses often get overlooked:
- Staff: 2-3 hours for setup, service and cleanup
- Transport: round trip plus loading time
- Material rental: warming equipment, tableware, linens
- No-show buffer: preparing 5-10% extra portions
💡 Example operational costs:
For 50 people lunch buffet:
- Staff (3 hours × €25): €75 = €1.50 per person
- Transport and time: €60 = €1.20 per person
- Material rental: €40 = €0.80 per person
- No-show buffer (10%): €1.20 per person
Total operational costs: €4.70 per person
Step 3: Calculate your minimum selling price
Now you've got your total costs per person. Add your desired profit margin on top.
Formula:
Minimum price excl. VAT = (Ingredient costs + Operational costs) ÷ (1 - Desired profit margin)
💡 Example calculation:
Total costs: €12.00 + €4.70 = €16.70 per person
Desired profit margin: 25%
Minimum price excl. VAT: €16.70 ÷ 0.75 = €22.27
Selling price incl. 9% VAT: €22.27 × 1.09 = €24.27 per person
Standard prices and margins
For business lunch buffets, these ranges are typical:
- Simple buffet: €18-25 per person
- Extensive buffet: €25-35 per person
- Premium buffet: €35-50 per person
A healthy profit margin for catering sits between 20-30%. Below 15% makes it tough to absorb unexpected costs. From analyzing actual purchasing data across different restaurant types, operations with margins under 18% struggle during supplier price spikes.
⚠️ Note:
With larger groups (100+ people) you can often work more efficiently and charge lower prices. With smaller groups (under 20 people) fixed costs become relatively higher.
Season and suppliers
Your ingredient costs fluctuate throughout the year. Update your prices quarterly at minimum:
- Winter: vegetables cost more, customers want heartier dishes
- Summer: salads get cheaper, fresh produce peaks
- Holidays: premium ingredients spike in price
Build a 5-10% buffer into your prices for unexpected supplier increases. Better to adjust down than lose money.
How do you calculate the selling price of a lunch buffet? (step by step)
Calculate all ingredient costs per person
Add up all the products that go on the buffet: bread, fillings, salads, warm appetizers, desserts. Calculate per person and add 10% for spoilage.
Add up operational costs together
Calculate staff, transport, materials and no-show buffer. Divide this by the number of people to get the cost per person.
Calculate minimum selling price with profit margin
Divide total costs by (1 - desired profit margin). At 25% profit: costs ÷ 0.75. Multiply by 1.09 for price including VAT.
✨ Pro tip
Track your actual vs estimated guest counts for each corporate client over 6 months. Most caterers discover their no-show estimates are 15-20% too optimistic, costing them serious profit.

Frequently asked questions
What profit margin should I calculate on a lunch buffet?
A healthy profit margin for catering runs 20-30%. Below 15% makes it nearly impossible to absorb unexpected costs like no-shows or sudden price increases.
Should I include VAT in my cost price calculation?
Never calculate with VAT included. For catering that's 9%, and including it makes your margin look artificially high. Always work with prices excluding VAT first.
How much extra should I add for no-shows?
Plan for 5-10% extra people. Business events usually have better attendance, but informal gatherings can see 15-20% no-shows.
What if the customer demands a lower price?
Offer alternatives: simpler menu, reduced service, or encourage a larger group size. Never drop below cost price plus 15% margin - you'll regret it.
How do I handle seasonal ingredient price changes?
Review and adjust your buffet prices every quarter. Winter vegetables and holiday premium items can spike costs by 20-30% overnight.
Should I charge the same rate for small vs large groups?
No - groups under 20 people need higher per-person rates because fixed costs like transport and setup don't scale down. Groups over 100 can often get volume discounts.
What's the biggest pricing mistake caterers make with buffets?
Forgetting staff overtime costs and no-show waste. Many caterers price based only on food costs and wonder why they're losing money on seemingly profitable jobs.
