Corporate lunches can be a goldmine, but also a pitfall. Many restaurants offer group packages without doing the math properly. The result: a full house, but no profit. In this article, you'll learn step by step how to calculate whether a corporate lunch offer is financially healthy.
The hidden costs of group packages
With a corporate lunch, you don't just look at the food cost of the meal. There are extra costs that you easily forget:
- Extra staff (service, kitchen)
- Preparation and mise-en-place
- Dishwashing and cleaning afterwards
- Table reservation (lost revenue from regular guests)
⚠️ Watch out:
Many entrepreneurs only calculate food cost and forget the extra labor costs. That can make your package unprofitable.
Calculate your total costs per person
For a healthy corporate lunch, you need to account for three cost items:
1. Food cost per person
Add up all ingredients: appetizer, main course, dessert, drinks, bread, butter. Don't forget garnish and sauces.
2. Extra labor costs
How many extra hours do you need? Multiply by your average hourly wage (including employer contributions).
3. Overhead and lost revenue
If you keep 30 seats occupied for a lunch at €25 per person, while you normally do €35 per cover, you're losing €10 per seat.
💡 Example:
Corporate lunch for 25 people at €28.00 incl. VAT:
- Food cost: €8.50 per person
- Extra labor costs: €3.00 per person (2 hours extra at €37.50/hour)
- Lost revenue: €2.00 per person (€30 regular vs €25.69 lunch excl. VAT)
Total costs: €13.50 per person
Selling price excl. VAT: €25.69. Margin: €12.19 (47%)
The healthy margin for group packages
For corporate lunches, a different margin calculation applies than regular service:
- Total costs: 50-60% of revenue (food + extra labor + lost revenue)
- Minimum margin: 40% to be profitable
- Healthy margin: 45-55% for sustainable growth
This is higher than the normal 65-70% costs because you put in extra effort and risk no-shows.
💡 Example calculation:
You want to offer a lunch at €32.00 incl. VAT:
- Selling price excl. VAT: €29.36
- Desired total costs: 55% = €16.15
- Food cost budget: €9.00
- Extra labor budget: €4.00
- Lost revenue budget: €3.15
Check: does your package fit within this budget?
Factor in no-show risk
With group packages, you always have cancellation risk. Account for this:
- 5-10% no-show is normal for corporate lunches
- You've already purchased ingredients and scheduled staff
- Build a 5% buffer into your pricing
If you count on 20 people but only 18 show up, your package still needs to be profitable.
⚠️ Watch out:
Always ask for a deposit or confirmation 48 hours in advance. This significantly reduces no-show risk.
Seasonal adjustments
Ingredient prices fluctuate by season. What was profitable in March can be unprofitable in July:
- Recalculate your food cost monthly
- Adjust your menu for significant price increases
- Use seasonal products to reduce costs
An app like KitchenNmbrs helps automatically update cost prices when suppliers raise their prices.
💡 Example seasonal menu:
Summer corporate lunch with seasonal products:
- Tomato-mozzarella: €2.80 (summer) vs €4.20 (winter)
- Grilled vegetables: €3.50 (summer) vs €5.80 (winter)
- Fresh herbs: €1.20 (summer) vs €2.40 (winter)
Summer menu savings: €3.90 per person
Calculate break-even point
Calculate at how many people you break even. This helps determine minimum group size:
Formula:
Break-even = Fixed costs / (Selling price per person - Variable costs per person)
Fixed costs are your extra labor costs and preparation. Variable costs are food and drinks per person.
💡 Break-even example:
Fixed preparation costs: €150
- Selling price: €25.69 excl. VAT
- Variable costs (food): €8.50
- Margin per person: €17.19
Break-even: €150 / €17.19 = 9 people
Below 9 people, you lose money on this package.
How do you calculate the profitability of a corporate lunch?
Calculate your total food cost per person
Add up all ingredients: appetizer, main course, dessert, drinks, bread, butter, sauces and garnish. Don't forget anything that comes to the table. Divide by number of people.
Work out extra labor costs
How many extra hours does preparation, service and dishwashing take? Multiply by your average hourly wage including employer contributions. Divide by number of people.
Check if your margin comes in above 40%
Add food cost and labor costs together. Subtract from your selling price excl. VAT. If your margin is below 40%, raise your price or lower your costs.
✨ Pro tip
Review your 3 best-selling group packages every quarter. Suppliers regularly raise prices, which can turn a profitable package into a loss-making one.

Frequently asked questions
What margin should I maintain for corporate lunches?
Minimum 40% margin to be profitable, preferably 45-55%. This is higher than regular service because you put in extra effort and risk no-shows.
Should I factor in lost revenue in my calculation?
Yes, if you're keeping tables occupied that normally generate more revenue. If your lunch brings in €25 per person but you normally do €35, you're losing €10 per seat.
How do I handle no-show risk with group packages?
Factor 5-10% no-show into your pricing. Ask for a deposit or confirmation 48 hours in advance to reduce the risk.
When is a corporate lunch priced too low?
When your total costs (food + labor + lost revenue) exceed 60% of your selling price. Then you don't have enough margin left for unexpected costs.
Should I factor in seasonal fluctuations in my pricing?
Yes, recalculate your food cost monthly. Ingredients can become 30-50% more expensive outside the season. Adjust your menu or prices for major fluctuations.
