Most care kitchens think calculating cost prices per meal is enough – but that's where margins slip through the cracks. Central cooking demands component-level precision because small errors multiply across thousands of portions. Break down every meal into its true cost components and you'll spot exactly where your budget bleeds.
Why cost price per component is crucial
Central cooking means producing massive volumes across multiple locations. A 10-cent miscalculation per portion equals €100 daily loss at 1000 portions. That's €36,500 vanishing from your annual budget.
⚠️ Note:
Always calculate excluding VAT. Care catering often falls under 9% VAT, but check this with your accountant.
The three main components
Every meal breaks into three distinct cost buckets:
- Main course: meat, fish, vegetarian alternative
- Side dishes: potatoes, rice, pasta, vegetables
- Sauces and garnish: gravy, butter, herbs, decoration
Calculate ingredient costs per component
Start with your recipes and dissect them into individual components. For each component, total up every single ingredient cost.
💡 Example: Chicken stew for 100 portions
Main course (chicken):
- Chicken fillet: 15 kg at €6.50/kg = €97.50
- Broth: 2 liters at €3.20/l = €6.40
- Herbs: €4.50
Cost price main course: €108.40 for 100 portions = €1.08 per portion
Account for trim loss and processing costs
Fresh products always create waste through peeling, cutting and trimming. This waste inflates your real cost price – and most kitchens ignore it.
Trim loss formula:
Actual cost price = Purchase price ÷ (Yield in %)
💡 Example: Fresh potatoes
Situation:
- Purchase price: €0.80/kg
- Peel loss: 15%
- Yield: 85%
Actual cost price: €0.80 ÷ 0.85 = €0.94/kg
Allocate overhead costs across components
Energy, water, packaging and labor represent overhead costs you must distribute fairly. From tracking this across dozens of restaurants, preparation time or ingredient value work as reliable allocation keys.
- Energy: preparation time × average costs per hour
- Packaging: direct costs per portion (containers, foil)
- Labor: preparation time × hourly wage kitchen staff
💡 Example: Overhead costs stew
For 100 portions chicken stew:
- Energy (2 hours cooking): €8.00
- Packaging: €0.12 per portion = €12.00
- Labor (1 hour prep): €18.00
Overhead per portion: €38.00 ÷ 100 = €0.38
Check your total cost price per meal
Add up all components and compare against your selling price. Care catering typically runs food costs between 35-45% of selling price.
Total cost price = Main course + Side dishes + Sauces + Overhead
⚠️ Note:
Care catering often has fixed contract prices. You can't simply raise prices, so cost price management is extra important.
Digital registration saves time
Manual calculations eat time and breed errors. Tools like KitchenNmbrs automatically calculate and track cost prices per component, instantly showing where margins face pressure.
How do you calculate cost price per component? (step by step)
Break recipes down into components
Divide each meal into main course, side dishes and sauces. Note all ingredients per component with exact quantities and purchase prices.
Calculate trim loss and yield
Measure how much usable product you have left after processing. Divide your purchase price by the yield percentage to get the actual cost price.
Allocate overhead costs fairly
Convert energy, packaging and labor costs to costs per portion. Use preparation time or ingredient value as allocation key.
Add up all components
Sum main course, side dishes, sauces and overhead for the total cost price per meal. Check if this falls within your desired food cost percentage.
✨ Pro tip
Track your 3 highest-volume meal components bi-weekly – they represent 60% of your total food spend. Master these costs and you control the majority of your margin risk.

Frequently asked questions
How often should I recalculate cost prices?
With every supplier price change, minimum monthly. Set calendar reminders to make this structural.
Should I include VAT in my cost price calculation?
No, always calculate excluding VAT. VAT paid to suppliers can usually be reclaimed from tax authorities.
What is a healthy food cost for care catering?
Between 35-45% is typical. Higher often means insufficient margin, lower can mean you're overpriced for the market.
How do I allocate labor costs across different dishes?
Use preparation time as your allocation key. A dish requiring 2 hours gets double the labor costs of a 1-hour dish.
Can I estimate cost prices instead of calculating them?
With large volumes, estimating becomes dangerously inaccurate. A 5-cent error per portion costs €18,250 annually at 1000 daily portions.
What's the biggest mistake in component cost calculation?
Forgetting seasonal price fluctuations for fresh ingredients. Lettuce can triple in winter, destroying your carefully calculated margins if you don't adjust monthly.
