Picture this: you've created an amazing new dish that customers absolutely love, but three months later you realize it's actually losing money with every plate served. Many talented chefs fall into this trap because they skip the crucial step of calculating food costs upfront. Here's how to develop profitable dishes from concept to final costing.
Start with your target audience and concept
Before choosing any ingredients, figure out who'll eat this dish and what they're willing to pay. A vegetarian pasta for lunch operates in a completely different price bracket than your signature dinner entrée.
- Lunch dishes: usually between €12-18
- Dinner main courses: usually between €22-35
- Signature dishes: €30+ possible
- Side dishes: €6-12
💡 Example:
You want a new pasta for the lunch menu. Similar pastas on your menu are priced at €15-16.
Target price: €15.50 incl. VAT = €14.22 excl. VAT
Determine your maximum ingredient costs
Once you've set your target price, you can work backwards to find your ingredient budget. Most restaurants aim for 28-35% food cost - anything higher starts eating into your profits fast.
Formula: Maximum ingredient costs = Selling price excl. VAT × (Food cost % ÷ 100)
💡 Example calculation:
Target price: €14.22 excl. VAT
Desired food cost: 30%
Maximum ingredient costs: €14.22 × 0.30 = €4.27
⚠️ Note:
Always calculate with the price excl. VAT. The price on your menu is inclusive of 9% VAT for food.
Develop the recipe within your budget
Now comes the creative part - building a delicious dish within your €4.27 budget. List every single ingredient with precise quantities per portion. Don't forget the small stuff that adds up.
- Main ingredient (pasta, meat, fish)
- Vegetables and herbs
- Sauces and oils
- Garnish and decoration
- Everything that goes on the plate
💡 Example pasta recipe:
- Pasta (100g): €0.35
- Chicken (120g): €1.80
- Mushrooms (80g): €0.45
- Cream sauce (60ml): €0.28
- Parmesan (15g): €0.42
- Herbs and oil: €0.25
Total: €3.55 (within budget of €4.27)
Test and refine portion sizes
Here's where theory meets reality. Make this dish 5-10 times and weigh everything religiously. You'll be surprised how much more sauce or oil you actually use compared to what's written down.
- Weigh ingredients for 5-10 portions
- Calculate the average per portion
- Add 5-10% margin for variation
- Update your food cost
⚠️ Note:
Chefs often give larger portions than intended. 20 grams extra chicken per portion costs you €2,600 per year at 100 portions per week.
Calculate the final food cost
Time for the moment of truth. Add up all those ingredient costs and see if you've stayed within budget. From analyzing actual purchasing data across different restaurant types, dishes that exceed their target food cost by even 2-3% can significantly impact annual profitability.
Control formula: Food cost % = (Total ingredient costs ÷ Selling price excl. VAT) × 100
💡 Final check:
Actual ingredient costs: €3.85
Selling price excl. VAT: €14.22
Food cost: (€3.85 ÷ €14.22) × 100 = 27.1% ✓
Document everything for your team
Write down the final recipe with military precision. Your future self (and your staff) will thank you. Consistency is what separates profitable restaurants from those that struggle with fluctuating costs.
- Ingredients with exact grams/milliliters
- Preparation steps
- Food cost per portion
- Allergens and dietary requirements
- Presentation and garnish
Digital tools like KitchenNmbrs can document recipes and automatically recalculate food costs when ingredient prices change.
From idea to food cost: step by step
Determine your target price and maximum ingredient costs
Look at similar dishes on your menu and determine a realistic selling price. Then calculate your maximum ingredient costs: selling price excl. VAT × desired food cost percentage.
Develop the recipe within your budget
Experiment with ingredients that together stay within your maximum costs. Make a list of all ingredients with exact quantities per portion, including garnish and sauces.
Test and weigh everything carefully
Make the dish 5-10 times and weigh all ingredients. Calculate the average per portion and add 5-10% margin for variation in practice.
Check your food cost percentage
Add up all ingredient costs and divide by your selling price excl. VAT. If you exceed your target, adjust the recipe or raise the price.
Document the final recipe
Write everything down: exact quantities, preparation method, food cost and allergens. This way your team can make the dish consistently and the food cost stays stable.
✨ Pro tip
Test each new recipe exactly 7 times during your first week, weighing every ingredient each time. This gives you real-world portion data that's far more accurate than theoretical calculations.

Frequently asked questions
What food cost percentage should I maintain for new dishes?
For restaurants, 28-35% is standard. Use 30% as your starting point. Signature dishes can sometimes stretch to 35%, while simple dishes should stay under 28%.
How much margin should I build in for variation in portions?
Add 5-10% to your calculated ingredient costs. In practice, chefs often give slightly larger portions, especially with sauces, garnish and oil. This buffer prevents nasty surprises when you calculate actual costs later.
What if my dish turns out too expensive for the target price?
You've got three options: reduce portion sizes, swap expensive ingredients for cheaper alternatives, or raise the selling price. Choose based on what fits your restaurant's positioning and what your customers will accept.
