Most restaurant owners underestimate how much their seasonings actually cost per dish. That €3.50 jar of basil might seem insignificant, but multiply it across hundreds of portions and you're looking at serious money. Here's how to calculate the true cost of every pinch and sprinkle.
Why include spices and herbs in your cost price?
That €3.50 basil jar doesn't seem like much until you break it down. Use it across 20 dishes and each portion carries €0.18 in basil costs alone. Serve 100 portions weekly? You're spending €936 annually on basil. Add oregano, paprika, salt, pepper and other seasonings, and you're easily hitting €0.50-€1.00 per dish just in spices.
⚠️ Watch out:
Many operators skip spices in their costing entirely. Fine dining establishments using saffron, vanilla pods or truffles can see €2-3 swings per dish from seasonings alone.
Calculate costs per gram or teaspoon
Spices come in jars and packets, but you need per-portion costs. First step: figure out jar weight and what your measuring spoons actually weigh.
💡 Example spice weights:
- 1 teaspoon salt: 6 grams
- 1 teaspoon paprika powder: 2.3 grams
- 1 teaspoon oregano (dried): 1.5 grams
- 1 teaspoon garlic powder: 3.1 grams
- 1 teaspoon black pepper: 2.1 grams
Weigh these once with a digital scale. Different brands vary slightly, but this gives you solid baseline numbers for calculations.
Formula for spices per portion
Cost per portion = (Purchase price jar ÷ Weight jar in grams) × Used weight per portion
💡 Example calculation:
Paprika powder jar: 100 grams for €2.80
- Price per gram: €2.80 ÷ 100 grams = €0.028 per gram
- Recipe calls for 1 teaspoon (2.3 grams) per portion
- Cost per portion: €0.028 × 2.3 = €0.064
Paprika powder costs €0.06 per portion
Calculate expensive spices separately
Premium spices demand individual attention. Saffron runs €15-30 per gram, vanilla pods cost €2-4 each, fresh truffles hit €800-2000 per kilo. These get calculated per pinch or slice, never averaged out.
💡 Example saffron:
Saffron €20 per gram, recipe uses 0.1 gram per paella portion
- Cost per portion: €20 × 0.1 = €2.00
- For 4-person paella: €0.50 saffron per person
Saffron alone adds €0.50 per paella portion
Spice blends and homemade mixes
Custom spice blends require ingredient-by-ingredient costing. That Provençal herb mix with thyme, rosemary, oregano and lavender? Calculate each component's cost, add them up, then divide by total blend weight.
- Record exact quantities of each ingredient used
- Calculate individual ingredient costs
- Sum up total blend expenses
- Divide by total weight for price per gram
Fresh herbs vs dried herbs
Fresh herbs cost more per gram but you typically use larger quantities. A €1.50 basil bunch (20 grams) runs €0.075 per gram. Dried basil at €2.50 per 25 grams costs €0.10 per gram, but you'll use less since it's more concentrated.
From years of working in professional kitchens, I've learned that fresh herb ratios can vary dramatically based on preparation method and dish type.
⚠️ Watch out:
Fresh herbs spoil quickly. Build 10-20% waste into your costing to account for spoilage and trimming.
Track spice costs digitally
Managing hundreds of spices manually gets overwhelming fast. Digital systems help you log every ingredient with precise pricing and quantities. You'll instantly see how seasonings impact your per-dish food costs.
Tools like KitchenNmbrs eliminate the need to recalculate oregano costs repeatedly and make supplier price updates simple.
How do you calculate spice costs per portion?
Gather purchase prices and weights
Note the purchase price and total weight of the jar or packet for each spice. Check the label for the exact weight in grams.
Measure quantities per recipe
Weigh how many grams of each spice you use per portion. Measure teaspoons and tablespoons with a kitchen scale for exact weights.
Calculate cost per gram
Divide the purchase price by the total weight: (€2.80 / 100 grams = €0.028 per gram). This is your base price for further calculations.
Multiply by used quantity
Cost per portion = price per gram × used grams per portion. At €0.028 per gram and 2.3 grams used: €0.028 × 2.3 = €0.064 per portion.
Add all spices together
Sum the costs of all spices in the dish. This gives you the total spice costs per portion that you include in your food cost calculation.
✨ Pro tip

Frequently asked questions
Do I really have to calculate every spice separately?
For basic seasonings like salt and pepper, use a standard €0.10-0.15 per portion. But expensive spices like saffron, vanilla or truffles need individual calculations since they dramatically impact food costs.
How often should I update spice costs?
Review purchase prices every 3-6 months or with new supplier deliveries. Spice prices fluctuate with seasons, harvests and global market conditions. Saffron and vanilla are especially volatile.
What if I buy spices in bulk?
Bulk purchasing reduces per-gram costs but consider shelf life and storage capacity. Divide bulk price by total weight for your per-gram rate, and factor in 5-10% waste for spoilage.
How do I handle spice blends that I make myself?
Calculate costs for each blend ingredient separately, sum them up, then divide by total weight. This gives you the per-gram price for your custom blend to use in recipe costing.
What about spices that lose potency over time?
Factor potency loss into your calculations, especially for expensive items. Six-month-old saffron might require 20% more to achieve the same flavor impact, effectively increasing your per-portion cost.
Do spices make a big difference in my food cost?
Simple dishes see €0.10-0.30 per portion in spice costs. Fine dining with premium seasonings can hit €2-5 per dish. Annually, untracked spice costs can drain hundreds to thousands from your margins.
