Are you leaving money on the table because your recipe book isn't connected to your pricing strategy? Most restaurant owners use recipes only in the kitchen, missing crucial opportunities for profitable pricing. This disconnect between kitchen operations and financial planning can silently drain your profits month after month.
From recipe to cost price: the foundation
Your recipe book holds every detail needed for accurate cost calculations. The challenge? Most recipes weren't written with finances in mind. They're filled with vague measurements like "a pinch of salt" or "season to taste" – useless for calculating exact costs in euros and cents.
💡 Example:
Carbonara recipe (typical kitchen version):
- Pasta: "200 grams per person"
- Bacon: "100 grams pancetta"
- Eggs: "2 pieces"
- Cheese: "handful of parmesan"
Cost calculations demand precise measurements and current prices.
Transform recipes into financial tools
Review each recipe and convert every vague measurement into exact quantities. That "handful" becomes "40 grams." The "splash" transforms into "15 ml." Yes, it's time-consuming upfront. But you'll use these precise measurements for months.
- Weigh all approximate quantities using a digital scale
- Record exact weights or volumes for every ingredient
- Include often-forgotten items: cooking oil, butter, seasonings, spices
- Account for garnishes and accompanying sauces
⚠️ Note:
Always calculate using pre-cooking weights. Raw pasta weighs 200 grams but doubles when cooked. For costing purposes, you'll price the original 200 grams.
Connect purchase prices to your recipes
With exact quantities established, you'll need current supplier prices for each ingredient. Review your recent invoices and record the per-kilogram cost of every item. Update these figures monthly – suppliers adjust prices more frequently than you might realize.
💡 Example carbonara breakdown:
Ingredients with current pricing:
- Pasta 200g: €0.60 (€3/kg)
- Pancetta 100g: €2.80 (€28/kg)
- Eggs 2 pieces: €0.50 (€0.25/piece)
- Parmesan 40g: €1.60 (€40/kg)
- Olive oil 10ml: €0.15 (€15/liter)
Total ingredient cost: €5.65
Factor in trim loss and preparation waste
Recipe books typically list finished portions, but you purchase raw ingredients. You buy whole fish but serve only fillets. This preparation loss significantly impacts your true costs – a mistake that costs the average restaurant EUR 200-400 per month in miscalculated pricing.
- Whole fish to usable fillet: 45-55% waste
- Large meat cuts to individual portions: 15-25% loss
- Root vegetables after peeling: 10-20% waste
- Leafy greens after trimming: 10-15% loss
Don't use the invoice price per kilogram. Calculate the actual cost per kilogram of usable product. With 50% trim loss, that €20/kg ingredient actually costs €40/kg for the portion you serve.
Convert cost price to menu price
Once you've determined the true cost per dish, calculate your selling price using the food cost formula:
Minimum selling price excl. VAT = Ingredient cost / (Target food cost % / 100)
💡 Example pricing calculation:
Carbonara ingredient cost: €5.65
Target food cost percentage: 30%
Minimum price before VAT: €5.65 / 0.30 = €18.83
Final menu price with 9% VAT: €18.83 × 1.09 = €20.52
Manual tracking vs. digital solutions
Spreadsheets work for small operations, but they become unwieldy fast. Managing 20 dishes means tracking hundreds of ingredients with constantly changing prices. Digital platforms like tools such as KitchenNmbrs automatically recalculate costs whenever you update supplier pricing.
⚠️ Note:
Refresh your supplier prices monthly at minimum. Price increases happen quietly, gradually inflating your food costs without obvious warning signs.
How do you calculate recipes through to menu prices?
Make quantities exact
Go through your recipe book and replace vague quantities with exact grams. "A handful of parmesan" becomes "40 grams of parmesan". Measure this with a kitchen scale.
Collect purchase prices
Note the kilogram price of each ingredient from your supplier invoices. Include trim loss: with 50% loss divide the purchase price by 0.5 to get the actual price.
Calculate cost price per dish
Multiply each ingredient (in grams) by the price per gram. Add up all ingredients for the total cost price of one portion.
Determine your selling price
Divide your cost price by your desired food cost percentage. With €6 cost price and 30% food cost: €6 / 0.30 = €20 excl. VAT. Multiply by 1.09 for the price incl. VAT.
✨ Pro tip
Track ingredient costs for your top 3 revenue-generating dishes every 2 weeks. If any dish exceeds 32% food cost, immediately adjust either portion sizes or menu pricing.

Frequently asked questions
Do I really need to include all ingredients, even salt and oil?
Absolutely – those "minor" ingredients accumulate quickly. A small drizzle of olive oil might seem negligible, but across 100 weekly portions, you're talking about meaningful cost differences. Every gram counts for accurate pricing.
How often should I update my purchase prices?
Monthly updates are essential, though weekly is better for high-volume operations. Suppliers adjust prices regularly without fanfare. Focus extra attention on your most expensive ingredients like premium meats and fresh seafood.
What if my chef has modified the recipes without documenting changes?
Shadow your kitchen team for a few service periods and measure actual ingredient usage. Chefs often use heavier portions of expensive ingredients than recipes specify, which can significantly impact your food costs without you realizing it.
Can't I just estimate what each dish costs me?
Estimates are notoriously unreliable and typically underestimate costs by 20-30%. Restaurant owners consistently forget secondary ingredients or work with outdated price assumptions. Precise calculations protect your profit margins.
