Last month, a restaurant owner told me they served 40 corporate lunches at €30 per head and wondered why they barely broke even. Many restaurants offer group packages without crunching the real numbers. The result: packed dining rooms with razor-thin profits.
The hidden costs of group packages
Corporate lunches involve more than just food costs. There are extra expenses that slip under the radar:
- 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
Corporate lunches require different margin calculations 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 runs higher than the normal 65-70% costs because you're putting in extra effort and risking 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
Group packages always carry 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 turn a profit.
⚠️ 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 drain money in July. From years of working in professional kitchens, I've seen restaurants get blindsided by seasonal price swings on their group packages:
- Recalculate your food cost monthly
- Adjust your menu for significant price increases
- Use seasonal products to reduce costs
Tools like KitchenNmbrs help 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
Recalculate your group lunch margins every 6 weeks during peak season. Ingredient costs can spike 30-40% without warning, turning profitable packages into money losers overnight.

Frequently asked questions
What margin should I maintain for corporate lunches?
Minimum 40% margin to be profitable, preferably 45-55%. This runs higher than regular service because you're putting in extra effort and risking 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.
