Premium ingredients can destroy your margins if you don't calculate properly. Most chefs focus on quality without checking if it fits their target selling price. Learn the exact formula to determine if that expensive ingredient stays profitable.
The formula for expensive ingredients
To verify if a premium ingredient works within your target selling price, calculate your maximum available budget per portion first.
Maximum ingredient budget = Target selling price excl. VAT × (Target food cost % ÷ 100)
💡 Example:
You want to sell a dish for €28.00 (incl. 9% VAT) with 30% food cost:
- Selling price excl. VAT: €28.00 ÷ 1.09 = €25.69
- Maximum ingredient budget: €25.69 × 0.30 = €7.71
So you've got €7.71 to spend on all ingredients combined.
Split your budget across all ingredients
Now you have your total budget. Break this down across every ingredient in the dish. Start with inexpensive base ingredients and see what remains for your costly main component.
💡 Example steak dish:
Budget: €7.71 for all ingredients
- Vegetables and garnish: €1.20
- Sauce and spices: €0.80
- Oil and butter: €0.40
- Other (bread, decoration): €0.60
Total side ingredients: €3.00
Budget for steak: €7.71 - €3.00 = €4.71
Check if your expensive ingredient fits the budget
You now know exactly how much you can allocate to your main ingredient. Calculate the grams needed and what that costs per portion.
⚠️ Note:
Don't forget trimming loss! If you buy whole fish for €18/kg but have 40% trimming loss, you're actually paying €30/kg for the fillet.
Say you want to serve 180 grams of steak and pay €32/kg for entrecôte:
- Cost per portion: 0.18 kg × €32 = €5.76
- Budget available: €4.71
- Shortfall: €5.76 - €4.71 = €1.05 per portion
This ingredient doesn't work within your target 30% food cost. From analyzing actual purchasing data across different restaurant types, this scenario happens more often than chefs expect.
Your options if it doesn't fit
If your expensive ingredient exceeds your target food cost, you have four choices:
- Raise the selling price: €1.05 shortfall means at least €1.16 price increase (incl. VAT)
- Reduce the portion: From 180 to 150 grams of steak saves €1.28
- Choose a cheaper ingredient: Find an alternative for maximum €26.17/kg
- Accept higher food cost: 33.1% instead of 30%
💡 Price increase calculation:
A shortfall of €1.05 per portion means:
- New minimum selling price excl. VAT: €8.76 ÷ 0.30 = €29.20
- Incl. 9% VAT: €29.20 × 1.09 = €31.83
- Price increase: from €28.00 to €31.83
When expensive ingredients make sense
Sometimes quality justifies a higher price. Expensive ingredients can work if:
- Your guests are willing to pay more for quality
- The ingredient sets you apart from competitors
- Your other dishes compensate with lower food cost
- It fits your positioning (fine dining, premium casual)
Always calculate first if it works within your margins. Then you can make an informed decision.
How do you calculate whether an expensive ingredient fits? (step by step)
Calculate your maximum ingredient budget
Divide your desired selling price (excl. VAT) by your desired food cost percentage. At €25.69 excl. VAT and 30% food cost you have €7.71 to spend on all ingredients combined.
Add up all side ingredients
Calculate what vegetables, sauces, garnish and other ingredients cost per portion. Subtract this from your total budget to see how much is left for your main ingredient.
Check whether your main ingredient fits the budget
Calculate the cost of your desired portion size of the expensive ingredient. Don't forget trimming loss! If it's more expensive than your remaining budget, you'll need to adjust one of your variables.

Frequently asked questions
How do I factor in trimming loss for expensive ingredients?
Divide the purchase price by the yield percentage. With 40% trimming loss you have 60% yield. A fish at €18/kg then costs €18 ÷ 0.60 = €30/kg for the usable part.
What if my competitor sells the same dish cheaper?
Check if your competitor really delivers the same quality. Maybe they use cheaper ingredients or smaller portions. Focus on your own margins and positioning rather than just competing on price.
Can I lower my food cost by reducing the portion?
Yes, but be careful your guests don't get disappointed. A smaller portion of high quality is often better accepted than a large portion of lower quality.
Should I recalculate costs after seasonal price changes?
Absolutely, especially for proteins and seasonal produce. Price swings of 20-30% aren't uncommon for items like lamb or certain fish. Check your most expensive ingredients monthly during volatile periods.
