Picture this: you're selling meal boxes for €30 each, thinking you're making good money, only to discover months later you've been losing €2 on every single box. Most caterers calculate ingredients but completely miss packaging, labor and overhead costs. Here's exactly how to calculate your real margin and avoid this costly mistake.
What is margin on meal boxes?
Margin is the difference between your selling price and your total costs per box. It's different from food cost because you've got way more expenses than just ingredients.
💡 Example:
Meal box for 4 people, selling price €32.00 incl. VAT:
- Ingredients: €12.00
- Packaging: €2.50
- Labor (prep/packing): €4.00
- Overhead: €3.00
Total costs: €21.50
Margin: €32.00 - €21.50 = €10.50 (32.8%)
All cost items for meal boxes
A meal box has way more cost items than a regular dish you'd serve in-house:
- Ingredients: All products that go in the box
- Packaging: Box, compartments, labels, instruction cards
- Labor: Preparation, portioning, packing
- Cooling/transport: Extra cooling costs, delivery
- Overhead: Share of rent, energy, insurance
⚠️ Note:
Most entrepreneurs completely forget labor costs. Packing a box takes 10-15 minutes. At €15/hour labor costs that's €2.50-3.75 per box.
Margin calculation step by step
The formula's straightforward, but you need to include every single cost:
Margin € = Selling price - Total costs
Margin % = (Margin € / Selling price) × 100
💡 Calculation example:
Family box 'Italian evening' - €28.00 incl. VAT:
- Pasta, sauce, vegetables, cheese: €9.50
- Packaging and labels: €2.20
- Labor (12 min at €15/hour): €3.00
- Overhead (10% of revenue): €2.80
Total costs: €17.50
Margin: €28.00 - €17.50 = €10.50
Margin percentage: (€10.50 / €28.00) × 100 = 37.5%
Standard margins for meal boxes
Healthy margins for meal boxes sit between 35% and 45%. That's higher than restaurant food cost because you don't have service staff, but you do have extra packaging and labor expenses.
- 35-40%: Standard for premium boxes with fresh ingredients
- 40-45%: Achievable with efficient production and smart purchasing
- Under 30%: Too little to stay profitable long-term
- Above 50%: Possible with luxury boxes or large volumes
Common mistakes in margin calculation
From tracking this across dozens of restaurants, these are the mistakes that kill profitability:
⚠️ Note:
Always calculate with your selling price including VAT if you're selling to end customers. For B2B sales you calculate excluding VAT.
- Forgetting labor costs: Packing and preparation takes real time and money
- Underestimating packaging costs: Sustainable packaging keeps getting more expensive
- Not including overhead: Meal boxes still use your kitchen space and energy
- Ignoring seasonal fluctuations: Ingredient prices swing wildly by season
Improving margin: practical tips
These adjustments will boost your margin without sacrificing quality:
- More efficient packaging: Fewer compartments, smarter layout design
- Batch production: Prepare multiple boxes simultaneously
- Seasonal menu: Use cheaper seasonal ingredients strategically
- Minimum order quantity: Negotiate fixed purchases with suppliers
💡 Practical tip:
Recalculate your margin weekly. Ingredient prices fluctuate constantly, especially for fresh products. Tools like a food cost calculator help you track this automatically without tedious manual calculations.
How do you calculate the margin on a meal box? (step by step)
Calculate all ingredient costs
Add up all products that go in the box: main ingredients, spices, oil, additions. Calculate per portion and multiply by number of people per box.
Add packaging and labor costs
Calculate costs of box, compartments, labels and instructions. Measure how much time packing takes and convert this to labor costs (time × hourly wage).
Add overhead and calculate margin
Add 8-12% overhead (rent, energy, insurance). Subtract total costs from selling price. Divide by selling price and multiply by 100 for percentage.
✨ Pro tip
Track your margin on your 3 top-selling boxes every Tuesday morning for 8 weeks straight. You'll spot pricing trends before they hurt your bottom line.

Frequently asked questions
Should I include VAT in my margin calculation?
For consumer sales, calculate with the price including 9% VAT. For B2B sales, calculate excluding VAT. You always base margin on what the customer actually pays.
How do I calculate labor costs for packing?
Time how many minutes it takes to pack one box. Multiply by your hourly wage including employer contributions. Example: 12 minutes × €15/hour = €3.00 labor costs per box.
What is a healthy margin for meal boxes?
A margin between 35% and 45% is standard for most operations. Under 30% makes long-term profitability difficult. Above 45% is achievable with premium positioning or high volumes.
How often should I recalculate my margin?
At least monthly, but weekly is better since ingredient prices fluctuate constantly. Pay extra attention during seasonal transitions or when suppliers change pricing. Focus on your top-selling boxes first.
