Calculating micro-green costs is like measuring perfume - a tiny amount packs tremendous value, but one miscalculation can drain your profits. Most chefs guess at these luxury ingredient costs, never knowing if they're making money or losing it. You'll master the exact math that turns expensive garnishes into profitable plate enhancers.
Why micro-greens seem so expensive
Micro-greens often cost €80-120 per kilo. That sounds extremely expensive compared to regular lettuce (€3-5/kg). But you only use 2-5 grams per plate, so the actual cost per portion is often reasonable.
💡 Example:
Micro basil costs €100 per kilo from your supplier:
- Per gram: €100 ÷ 1000 = €0.10
- Per portion (3 grams): 3 × €0.10 = €0.30
Cost per plate: €0.30
The formula for micro-greens per portion
The calculation is straightforward, but you need to know exactly how much you use:
Cost per portion = (Cost price per kg ÷ 1000) × Grams per portion
⚠️ Watch out:
Weigh your portions several times to see how much micro-greens you actually use. Many chefs think 2 grams, but use 5 grams. That's 150% more in costs.
Edible flowers: calculate even more precisely
Edible flowers are often sold per piece or per container of X grams. You need to convert to cost per flower:
💡 Example:
Violets: €18 for a container of 50 flowers
- Per flower: €18 ÷ 50 = €0.36
- Per plate (2 flowers): 2 × €0.36 = €0.72
Cost per plate: €0.72
Factor shelf life into your calculation
Micro-greens and edible flowers spoil quickly. Factor in 10-20% waste in your cost price:
- Actual cost = Purchase cost × 1.15 (at 15% waste)
- Store in refrigeration between 2-4°C
- Use within 3-5 days of delivery
- Check daily for brown leaves or wilted flowers
Impact on your food cost
After managing kitchen operations for nearly a decade, I've seen luxury garnish quickly increase food costs. Check if it fits your pricing:
💡 Example:
Dish with micro-greens and edible flowers:
- Base ingredients: €8.50
- Micro-greens (3g): €0.35
- Edible flowers (2 pieces): €0.80
- Waste (15%): €1.47
Total cost price: €11.12
At a selling price of €32 (excl. VAT €29.36), your food cost is: 37.9%. That's high for most restaurants.
Compare alternative suppliers
Prices for micro-greens vary enormously between suppliers:
- Local growers: often more expensive, but fresher
- Wholesale: cheaper, but minimum order quantities
- Specialized suppliers: wide range, stable quality
- Grow your own: lowest cost, but time investment
⚠️ Watch out:
Factor in shipping and minimum order quantities. Cheap micro-greens with high shipping costs can end up being more expensive.
How do you calculate micro-greens cost per portion? (step by step)
Determine the exact amount per portion
Weigh how much micro-greens or edible flowers you actually use per plate. Do this a few times to get an average. Many chefs underestimate.
Calculate the cost per gram or per piece
Divide the purchase price by the number of grams (for micro-greens) or by the number of pieces (for flowers). For example: €100/kg micro-greens = €0.10 per gram.
Factor waste into your cost price
Add 10-20% waste to your costs due to short shelf life. Multiply your cost price by 1.15 at 15% waste to get the actual costs.
✨ Pro tip
Weigh 10 micro-green portions during your next prep session and calculate the average weight. This gives you an accurate baseline cost that eliminates guesswork from your food costing.

Are micro-greens worth it for my food cost?
It depends on your pricing. For fine dining (€35+ main courses), micro-greens fit. For casual dining, they can make your food cost too high.
How long can I store micro-greens without waste?
Micro-greens stay fresh for 3-5 days in refrigeration between 2-4°C. Store them in the original packaging and check quality daily.

Yes, try young leaves from regular vegetables, herbs from your own garden, or seasonal alternatives. These also add color and flavor for less money.
How do I prevent micro-greens from becoming too expensive?
Use them only on your most expensive dishes, weigh portions precisely, and alternate with seasonal alternatives. Also check if your price gives enough margin.
