Premium spices cost restaurants an average of €300-500 monthly in hidden expenses due to miscalculated portions. Most chefs sprinkle saffron or vanilla without knowing their actual per-serving cost. Here's how to calculate margins on dishes with expensive spices so you'll know if you're actually turning a profit.
Why expensive spices can eat into your margin
Saffron costs €15,000 per kilo. Vanilla pods €400 per kilo. Truffle €3,000 per kilo. Even tiny amounts add up fast. The problem: many chefs think 'it's just a pinch' without calculating what that pinch actually costs.
⚠️ Watch out:
A teaspoon of saffron (0.5 gram) costs €7.50. That's more than some main ingredients of your entire dish.
Calculate the actual costs per portion
Convert expensive spices into grams or pieces per portion. Then you'll immediately see what it costs.
💡 Example: Saffron risotto
You're making risotto for 4 people and using 0.2 gram of saffron:
- Saffron: €15,000/kg = €15 per gram
- 0.2 gram saffron = €3.00 total
- Per portion: €3.00 / 4 = €0.75
Saffron costs €0.75 per portion
Add up all ingredient costs
Total all costs: main ingredients, regular spices, and the expensive ones. Many chefs forget the pricey spices entirely - a mistake that costs the average restaurant EUR 200-400 per month in miscalculated margins.
💡 Example: Complete cost price risotto
Ingredients per portion:
- Risotto rice: €0.45
- Broth: €0.30
- Wine: €0.25
- Parmesan: €0.85
- Butter: €0.15
- Saffron: €0.75
Total cost price: €2.75 per portion
Calculate your food cost percentage
Now figure out if your dish is still profitable. Use the standard food cost formula: Food cost % = (Ingredient costs / Selling price excl. VAT) × 100
💡 Example: Food cost calculation
You sell the risotto for €18.50 incl. VAT:
- Selling price excl. VAT: €18.50 / 1.09 = €16.97
- Ingredient costs: €2.75
- Food cost: (€2.75 / €16.97) × 100 = 16.2%
That's a healthy margin - under 30%
What if your food cost gets too high?
If expensive spices push your food cost above 35%, you've got three options:
- Raise your selling price: Guests expect dishes with saffron or truffle to cost more
- Use less spice: Often you won't taste the difference between 0.2 and 0.15 gram of saffron
- Find alternatives: Turmeric also gives yellow color, vanilla extract costs less than vanilla pods
⚠️ Watch out:
Never lower quality to save costs. Guests notice the difference between real saffron and cheap alternatives.
Keep track of spice prices
Prices of expensive spices fluctuate wildly. Saffron can jump from €12,000 to €18,000 per kilo. Regularly check your purchase prices and adjust your cost calculations.
Tools like a food cost calculator help you track ingredient prices centrally and immediately see how price changes affect your margins.
How do you calculate the margin on dishes with expensive spices?
Convert spices to cost per portion
Divide the kilo price by 1000 to get the price per gram. Multiply by the number of grams you use per portion. For saffron: €15,000/kg = €15/gram.
Add up all ingredient costs
Make a list of all ingredients including the expensive spices. Calculate what each ingredient costs per portion and add everything together for the total cost price.
Calculate your food cost percentage
Divide the total ingredient costs by your selling price excl. VAT and multiply by 100. If you come out above 35%, consider a higher selling price or using less spice.
✨ Pro tip
Weigh your saffron portions for exactly 14 days to establish your actual usage pattern. Most chefs discover they're using 40% more than calculated, which explains missing profits.

Frequently asked questions
How much saffron should I use per portion?
For risotto, 0.05-0.1 gram of saffron per portion gives enough taste and color. More than 0.2 gram often isn't noticed but costs significantly more.
Can I use cheaper alternatives for expensive spices?
For color you can use turmeric instead of saffron, and vanilla extract instead of vanilla pods. But the taste differs - always test first. Your customers might notice the change.
How often should I check prices of expensive spices?
At least every 3 months. Prices of saffron, vanilla and truffle can swing 20-30% within a season due to harvests and demand fluctuations.
Should I include VAT when calculating the cost price of spices?
No, always calculate with purchase prices excluding VAT. You can reclaim VAT from the tax authority, so it's not a real cost for your business.
What if my food cost goes above 40% because of expensive spices?
Then you're probably losing money on that dish. Raise your selling price, use less spice, or reserve expensive spices only for premium dishes with higher margins.
How do I price dishes with seasonal expensive ingredients like fresh truffles?
Create two menu versions - one for truffle season with higher prices, one without. Track truffle costs weekly since prices can double overnight during peak season.
