Buffet catering typically runs 25-35% food cost of the per-person selling price. You'll save on labor since guests serve themselves, but you'll face higher waste from surplus preparation. Every guest gets served simultaneously, creating unique cost challenges.
Why food cost differs at buffets
Running buffets flip the script on traditional food costing. You're calculating per person rather than per plate, and everyone eats at once. Here's how this changes your numbers:
- Reduced service staff requirements (cuts labor costs significantly)
- Built-in 10-20% surplus becomes unavoidable
- High-demand items disappear while others sit untouched
- Zero mid-event adjustments possible
💡 Example buffet for 100 people:
Selling price: €35.00 per person (excl. 9% VAT = €32.11)
- Ingredients for 100 people: €950
- 10% surplus (waste): €95
- Total food cost: €1,045
Food cost: €1,045 ÷ (100 × €32.11) = 32.5%
Food cost benchmarks by buffet type
Your target food cost shifts dramatically based on what you're serving:
- Lunch buffet (sandwiches, salads): 20-28%
- Hot meal buffet: 28-35%
- Luxury buffet (fish, meat, premium ingredients): 35-42%
- Dessert buffet: 15-25%
⚠️ Note:
Always calculate using the price excl. VAT. The €35.00 you charge includes 9% VAT, so you calculate your food cost based on €32.11 per person.
Including surplus and waste
Surplus isn't optional—it's mandatory. Guests won't clean every tray, and empty chafing dishes spell disaster for your reputation. Most kitchen managers discover too late that skimping on surplus creates more problems than overspending. Build these percentages into every quote:
- Lunch buffet: 5-10% surplus
- Dinner buffet: 10-15% surplus
- With uncertain numbers: 15-20% surplus
💡 Calculation example with surplus:
Buffet for 80 people, ingredients €8.50 per person:
- Basic ingredients: 80 × €8.50 = €680
- 15% surplus: €680 × 1.15 = €782
- Selling price: €28.00 per person (€25.69 excl. VAT)
Food cost: €782 ÷ (80 × €25.69) = 38.1%
Popular vs. less popular dishes
Buffet psychology is predictable. Guests gravitate toward comfort foods and avoid anything unfamiliar. Plan accordingly:
- Popular (meat, pasta, potatoes): plan for 120-150% of normal portion
- Average (vegetables, salads): plan for 80-100% of normal portion
- Less popular (fish, exotic dishes): plan for 60-80% of normal portion
Calculate cost price per person
Accurate costing means breaking down every ingredient, then adding your expected surplus:
💡 Step-by-step calculation:
Buffet for 60 people:
- Meat: 60 × 180g × €18/kg = €194.40
- Vegetables: 60 × 150g × €4/kg = €36.00
- Potatoes: 60 × 200g × €1.50/kg = €18.00
- Sauces and garnish: €45.00
Subtotal: €293.40
With 12% surplus: €293.40 × 1.12 = €328.61
Cost price per person: €328.61 ÷ 60 = €5.48
Fixing high food costs
Food cost creeping above 35% for standard buffets? You've got options:
- Swap expensive ingredients for budget-friendly alternatives
- Cut variety but increase quantities of crowd-pleasers
- Raise your per-person selling price
- Tighten quantity planning to reduce waste
⚠️ Note:
Catering comes with additional costs such as transport, setup and on-site staff. Plan for total costs of 55-70% of your revenue for a healthy margin.
How do you calculate food cost for a running buffet?
Calculate ingredients per person
Make a list of all dishes and calculate how much you need per person. Add up all ingredients: meat, vegetables, side dishes, sauces and garnish. Multiply by the number of guests.
Add surplus and waste
Add 10-20% surplus to your ingredient costs. This is necessary because not everything gets eaten and you want to prevent the buffet from running empty. With uncertain guest numbers, calculate with more surplus.
Calculate food cost percentage
Divide your total ingredient costs (including surplus) by your total revenue excl. VAT. Multiply by 100 for the percentage. A healthy food cost for buffets is between 25-35%.
✨ Pro tip
Document consumption patterns for each buffet item over your next 8 events. You'll spot trends that let you reduce waste by 15-20% while ensuring popular dishes never run empty.

Frequently asked questions
Why is food cost lower at buffets than at restaurants?
Buffets require fewer service staff since guests serve themselves. This labor savings lets you accept slightly higher food costs while maintaining profitability. But you'll deal with more waste from required surplus preparation.
How much surplus should I plan for at a buffet?
Lunch buffets need 5-10% surplus, dinner buffets require 10-15%. If guest counts are uncertain, bump that to 15-20% to avoid running short.
How do I prevent too much waste at buffets?
Track consumption patterns from previous events and adjust accordingly. Plan generous portions for meat and pasta, moderate amounts for vegetables, and smaller quantities for unfamiliar dishes.
Is 40% food cost acceptable for a luxury buffet?
Luxury buffets with premium ingredients can justify 35-42% food costs. Just ensure your other expenses stay controlled to maintain healthy overall margins.
Should I include VAT in my food cost calculation?
Never include VAT in food cost calculations. If you charge €35 per person with 9% VAT, your actual selling price is €32.11—use that figure for percentage calculations.
What's the biggest mistake caterers make with buffet costing?
Underestimating surplus requirements and not tracking which dishes actually get consumed. This leads to either running out of food or massive waste, both killing profitability.
