You're running a restaurant where guests pay €75 for the entire evening – four courses, wine pairing, the works. But how do you know if you're actually making money? Fixed-price dining creates a different cost structure than traditional à la carte service.
What is a fixed price concept?
Fixed price dining means guests pay one set amount for their complete evening experience. This could be a 3-course meal, elaborate tasting menu, or all-inclusive night out. Common formats you'll see:
- Chef's tasting menu (5 courses with wine pairing)
- Seasonal prix fixe (rotating dishes, set price)
- All-you-can-eat concepts (unlimited food and drinks)
- Themed evenings (like a €45 BBQ night)
Calculate your total cost per person
You're not pricing individual dishes anymore – you're pricing the entire guest experience. Add up every cost that guest will generate during their visit.
💡 Example:
4-course menu priced at €65 incl. VAT (€59.63 excl. VAT):
- Starter: €3.20
- Soup course: €2.80
- Main dish: €8.50
- Dessert: €2.10
- Bread service + amuse-bouche: €1.40
Total ingredient cost: €18.00 per guest
Calculate your margin
The math stays the same as individual dishes, but now you're working with the complete menu cost:
Food cost % = (Total ingredient costs / Selling price excl. VAT) × 100
💡 Example calculation:
Using our numbers from above:
- Ingredient costs: €18.00
- Menu price excl. VAT: €59.63
- Food cost percentage: (€18.00 / €59.63) × 100 = 30.2%
That's a solid margin for most restaurant concepts.
Don't forget the drinks
Including beverages? Add those costs too. But here's the tricky part – you need to estimate average consumption per guest.
⚠️ Note:
Unlimited drinks are risky business. Some guests will drink way more than others. Build in a 20% buffer above your calculated average consumption.
💡 Example with beverages:
Menu + wine pairing €89 incl. VAT (€81.65 excl. VAT):
- Food costs: €18.00
- 4 wine pairings at €2.20 each: €8.80
- Welcome cocktail: €1.50
- Coffee service + petit fours: €1.80
Total costs: €30.10 → Food cost: 36.9%
Seasonal price swings
Fixed-price restaurants often change menus seasonally while keeping prices stable. Your costs will fluctuate – track them monthly. From tracking this across dozens of restaurants, I've seen food costs swing 8-12% between seasons if you don't adjust recipes.
- Update ingredient prices monthly
- Verify your food cost percentages still work
- Swap expensive ingredients for seasonal alternatives
- Use local, in-season products to control costs
Industry benchmarks for fixed pricing
Target food cost percentages vary by concept type:
- Fine dining tasting menus: 28-35%
- Casual prix fixe dining: 25-32%
- All-inclusive concepts: 35-45% (higher risk from unlimited consumption)
- Specialty theme nights: 25-35%
⚠️ Note:
All-inclusive formats run higher food costs because you're absorbing consumption risk. Price accordingly – charge enough to cover the heavy drinkers and big eaters.
Why fixed pricing works financially
Set menu pricing offers several business advantages:
- Revenue predictability: You know exactly what each reservation generates
- Smarter purchasing: Order precise quantities based on covers booked
- Reduced waste: No surprise leftovers from unpopular dishes
- Higher check averages: Guests typically spend more than they would ordering à la carte
Food cost calculators can track all your menu components and automatically compute per-person costs, including seasonal price adjustments.
How do you calculate the margin on a fixed price menu?
Make a list of all components
Write down each component of your menu: all courses, bread, amuses, and any drinks. Don't forget anything, not even the small things like butter or olive oil.
Calculate the cost per component
For each course, add up all ingredients and calculate the cost per portion. Use current purchase prices from your suppliers.
Add everything up to total cost per person
Sum all components to one amount per guest. This is your total ingredient cost for the complete menu.
Calculate your food cost percentage
Divide your total cost by your selling price excluding VAT and multiply by 100. Aim for 25-35% for a healthy margin.
✨ Pro tip
Track your 2 most popular menu options weekly for the first 6 months. These will represent 70% of your volume, so keeping their costs in line protects most of your profit margin.

Frequently asked questions
What if guests drink more than expected with unlimited packages?
Build in a 20% safety buffer above your calculated average consumption per guest. Track actual consumption for your first 2-3 months and adjust your estimates accordingly.
How often should I recalculate my menu costs?
Review ingredient prices monthly, especially for seasonal items. If any supplier raises prices by more than 10%, immediately recalculate your food cost percentage.
Should I include VAT in my cost calculations?
Never include VAT in cost calculations. Always work with prices excluding VAT – so that €65 menu becomes €59.63 excl. 9% VAT for your math.
Can I run multiple menus with different profit margins?
Absolutely – calculate each menu's costs separately. You might run a budget option at 32% food cost and a premium menu at 28% food cost.
