How do I calculate the margin on a meal subscription with fixed monthly intake?

📝 KitchenNmbrs · updated 16 Mar 2026

A catering company serving 1,200 meals monthly to three schools discovered their 18% margin on paper was actually just 8% after including transport and packaging costs. Fixed meal subscriptions seem predictable, but hidden expenses often slash profits more than expected. Most caterers focus only on ingredient costs while overlooking the full picture.

What makes meal subscriptions different?

Meal subscriptions give you exact monthly volumes, but they come with unique challenges:

  • Fixed costs that you need to spread across the entire subscription
  • Transport to multiple locations
  • Special packaging for keeping food warm
  • Contractually fixed prices (you can't just raise them)

The complete cost structure

For accurate margin calculations, you must include every expense - not just ingredients:

💡 Example cost structure:

School cafeteria, 500 meals per month at €4.50:

  • Food cost: €1.35 per meal (30%)
  • Packaging: €0.25 per meal
  • Transport: €0.15 per meal
  • Labor for preparation: €0.45 per meal (10%)
  • Overhead: €0.30 per meal

Total costs: €2.50 per meal

Calculating margin: the formula

Your margin calculation follows this structure:

Margin per meal = Selling price - Total costs per meal

Margin % = (Margin per meal / Selling price excl. VAT) × 100

⚠️ Note:

Always calculate with the price excluding VAT. Meals fall under 9% VAT, so €4.50 incl. VAT = €4.13 excl. VAT.

Spreading fixed costs across the subscription

Meal subscriptions often carry fixed costs per location that require distribution:

  • Setup costs: First delivery, introduction, administration
  • Monthly fixed costs: Account management, invoicing
  • Minimum delivery costs: You still need to drive even with small orders

💡 Example fixed costs:

School cafeteria with 500 meals/month:

  • Setup costs: €200 (one-time, spread over 12 months = €16.67/month)
  • Account management: €50/month
  • Minimum delivery costs: €75/month

Total fixed costs: €141.67/month = €0.28 per meal

Accounting for seasonal fluctuations

Based on real restaurant P&L data, schools and care facilities show seasonal patterns that impact margins:

  • School holidays: Lower intake, fixed costs remain
  • Illness periods: Care facilities may suddenly order less
  • Ingredient prices: Seasonal vegetables vary greatly in price

Realistic margins for meal subscriptions

Typical margins in meal catering fall within these ranges:

  • School cafeterias: 15-25% net margin
  • Care facilities: 20-30% net margin (higher price, more service)
  • Corporate catering: 25-35% net margin (premium segment)

⚠️ Note:

Margins below 15% create risk with meal subscriptions. You have little room for unexpected costs or supplier price increases.

Tools for margin tracking

Food cost management systems help you:

  • Automatically calculate all costs per meal
  • Spread fixed costs across your subscriptions
  • Monitor seasonal fluctuations and adjust
  • See per customer which subscriptions are most profitable

How do you calculate the margin on a meal subscription?

1

Gather all variable costs per meal

Add up: food cost, packaging, transport per meal and labor for preparation. Don't forget small cost items like labels, napkins or extra sauces.

2

Calculate fixed costs per meal

Divide your monthly fixed costs (setup, account management, minimum delivery costs) by the number of meals per month. This gives you the fixed costs per meal.

3

Calculate your total cost price

Add variable costs per meal to fixed costs per meal. This is your actual cost price per meal including all overhead.

4

Calculate your margin percentage

Subtract your total cost price from your selling price excl. VAT. Divide this by your selling price excl. VAT and multiply by 100 for your margin percentage.

✨ Pro tip

Review your 5 largest subscription contracts every 6 weeks for actual versus projected margins. Food price inflation can erode a 22% margin to 16% within just two quarters if you're not tracking closely.

Frequently asked questions

Should I include VAT in my margin calculation?

No, always calculate with prices excluding VAT. Meals fall under 9% VAT, so €4.50 incl. becomes €4.13 excl. VAT for your calculation.

How do I spread setup costs across a long-term contract?

Spread one-time setup costs over the expected contract duration. With a 2-year contract you divide €200 setup over 24 months = €8.33 per month in additional costs.

What if a school orders less during holidays?

Calculate an average over the whole year. If a school orders 500 meals for 10 months and 0 for 2 months, your average is 417 meals per month.

What margin is realistic for school cafeterias?

Between 15-25% net margin is common. Below 15% becomes risky because you have little buffer for unexpected costs or price increases.
