A school cafeteria serving 300 students daily can lose €15,000 annually if their meal costs are just 20 cents off target. Many cafeterias calculate too generously and exceed their budget, or too tightly which affects quality. You'll discover exactly how to calculate what each meal costs, including all hidden expenses.
What's included in the cost per meal?
The cost of a school meal consists of more than just the ingredients on the plate. You need to include all costs that are directly related to making that meal.
💡 Example cost calculation:
Spaghetti bolognese for 100 students:
- Ingredients: €180 (ground meat, pasta, vegetables, sauce)
- Energy (gas, electricity): €15
- Packaging (plates, cutlery): €8
- Labor (2 hours cooking at €18/hour): €36
Total costs: €239 for 100 portions = €2.39 per meal
Calculate ingredient costs
Start with all ingredients that go into the meal. Also include small things like spices, oil and salt. These seem minor, but add up at large volumes.
- Main ingredients (meat, fish, vegetables)
- Side products (rice, pasta, potatoes)
- Sauces and spices
- Oil, butter for preparation
- Garnish or decoration
⚠️ Note:
Calculate with purchase prices including VAT. School cafeterias usually can't reclaim VAT, so the price you pay is your actual cost.
Labor costs per meal
Labor costs are often the largest cost item after ingredients. Don't just calculate with gross wages, but also with employer contributions.
Labor cost formula:
Total labor costs per hour = Gross wage × 1.4 (for employer contributions)
💡 Example labor costs:
Kitchen staff member earns €15/hour gross:
- Actual costs: €15 × 1.4 = €21/hour
- For 200 meals you need 3 hours
- Labor costs: 3 × €21 = €63
- Per meal: €63 ÷ 200 = €0.32
Energy and overhead costs
Gas, electricity and water cost money with every meal you make. Calculate this as a percentage of your ingredient costs or as a fixed amount per meal.
- Stove and ovens (gas/electricity)
- Refrigeration and freezers
- Dishwasher and hot water
- Kitchen lighting during preparation
Typical energy costs are between 8-12% of ingredient costs. At €2.00 ingredients per meal that's €0.16 to €0.24 in energy.
Packaging and serving costs
Plates, cutlery and napkins also cost money. At large volumes these are small amounts per meal, but they do add up to your total cost.
💡 Example packaging costs:
- Disposable plate: €0.08
- Plastic cutlery: €0.05
- Napkin: €0.02
- Total per meal: €0.15
Include food waste
Not all ingredients you purchase end up on the plates. Some is lost through trimming waste, spoilage or leftovers that remain. This is the kind of thing you only learn after closing your first month at a loss.
Calculate with 5-10% waste on top of your ingredient costs. At €2.00 ingredients that becomes €2.10 to €2.20 actual costs.
⚠️ Note:
Track waste by meal type. Salads have more loss than soup. Adjust your purchasing based on this to stay within budget.
Total cost formula
Cost per meal =
(Ingredients + Waste) + Labor + Energy + Packaging
Dividing all costs by the number of meals served gives you the exact cost per portion.
How do you calculate the cost per meal? (step by step)
Gather all ingredient costs
Make a list of all ingredients that go into the meal, including spices, oil and small additions. Add up the purchase prices and add 5-10% for waste.
Calculate labor costs per meal
Count the hours needed for purchasing, preparation, cooking and cleanup. Multiply by €21/hour (including employer contributions) and divide by number of meals.
Add energy and packaging costs
Calculate 8-12% of ingredient costs for energy. Add packaging costs per meal (plate, cutlery, napkin). Sum all costs and divide by number of meals for the total cost.
✨ Pro tip

Frequently asked questions
How often should I recalculate my costs?
Recalculate costs when suppliers change their prices, usually each quarter. Also when you have new recipes or notice you're exceeding your budget.
Should I include VAT in my cost calculation?
Yes, school cafeterias usually can't reclaim VAT. Always calculate with prices including VAT as you pay them to suppliers.
What's a realistic cost per warm school meal?
Typical costs range between €2.50 and €4.00 per meal, depending on ingredient quality and portion size. Budget meals can be lower, premium meals higher.
How do I calculate labor costs if I pay different wages?
Create a weighted average of all hourly wages multiplied by 1.4 for employer contributions. Or calculate per position separately and add the costs together.
Should I include fixed costs like rent in the meal cost?
For cost per meal you only calculate variable costs (ingredients, labor, energy). Fixed costs like rent and insurance go into your total budget calculation.
How do I handle seasonal price fluctuations in vegetables?
Calculate separate costs for summer and winter menus, or use annual average prices. Track your highest-cost vegetables monthly and substitute when prices spike above 15% of normal.
