Last month, a catering company lost €800 on a team-building BBQ because they calculated the margin as one lump sum instead of splitting activity and catering costs. Combo events need separate margin calculations for each component, plus different VAT rates. You'll also need to account for extra staff, materials, and logistics that don't exist in catering-only jobs.
The cost structure of a combo event
Corporate outings that mix activity and catering create different cost categories, each requiring its own margin approach:
- Activity costs: materials, instruction, venue
- Catering costs: ingredients, preparation, tableware
- Personnel costs: activity instructor + kitchen/service staff
- Logistics costs: transport, setup, breakdown
⚠️ Note:
Activities carry 21% VAT while catering gets 9% VAT. Split your quote into two separate line items for accurate VAT calculations.
Margin calculation per component
Handle activity and catering as distinct profit centers. Each should hit its own target margin:
- Activity margin: typically 40-60% (higher because it's specialized)
- Catering margin: usually 60-70% (similar to standalone catering gigs)
- Logistics: pass through at cost plus 20-30% markup
💡 Example calculation:
Corporate workshop + lunch for 20 people
- Activity costs: €300 (materials + 3-hour instructor)
- Catering costs: €180 (€9 per person food cost)
- Transport/setup: €120
- Total costs: €600
Target revenue: activity €750 + catering €600 = €1,350 total
Margin: (€1,350 - €600) / €1,350 = 55.6%
Process VAT correctly
The VAT split dramatically affects your net margin calculation:
- Activity: 21% VAT → €750 including becomes €619.83 excluding
- Catering: 9% VAT → €600 including becomes €550.46 excluding
- Total excluding VAT: €1,170.29
Your real margin becomes: (€1,170.29 - €600) / €1,170.29 = 48.7%
💡 Practical example:
Team building + BBQ for 30 people
- Team building: €900 including 21% VAT = €743.80 excluding
- BBQ catering: €1,200 including 9% VAT = €1,101.38 excluding
- Total costs: €850
Margin: (€1,845.18 - €850) / €1,845.18 = 53.9%
Factor in risk elements
Combo events carry additional risks that can destroy your margin - something most kitchen managers discover too late after their first outdoor disaster:
- Weather: outdoor activities get cancelled last-minute
- No-shows: you prep for 20, only 17 arrive
- Timing: activity runs long, catering sits cold
- Venue: surprise costs for electricity, water, waste disposal
Build a risk buffer of 5-10% into your total cost price. It's insurance you can't afford to skip.
⚠️ Note:
Always set a minimum participant count in your contract. Without it, your margin vanishes completely if too many people bail.
Digital support for complex calculations
Manual calculations with this many variables lead to costly mistakes. Tools like KitchenNmbrs support you with:
- Per-person cost price calculations for catering components
- Recipe management for standard catering items
- Margin tracking across different event types
You'll track activity costs separately, but for catering you get precise insight into food costs and profitability.
How do you calculate the margin on a combo event? (step by step)
Split all costs into categories
Distinguish between activity costs (materials, instruction), catering costs (ingredients, preparation) and logistics costs (transport, setup). This way you see where your profit comes from.
Calculate target margin per component
Activities can have 40-60% margin, catering 60-70%. Add up all costs and determine your minimum selling price per component to achieve these margins.
Process VAT correctly in your quote
Split your quote: activities at 21% VAT, catering at 9% VAT. Calculate your actual margin based on prices excluding VAT.
Add a risk buffer
Add 5-10% extra to your cost price for unforeseen circumstances like bad weather, no-shows or activities running over. Agree on a minimum number of participants.
✨ Pro tip
Create a standard combo event calculator with your target percentages for each cost category. For every new quote, plug in the specific amounts and you'll see your true margin within 3 minutes instead of spending an hour on spreadsheets.

Frequently asked questions
What VAT applies to activities versus catering?
Activities get hit with 21% VAT, catering only 9% VAT. Split your quote into two separate line items and calculate margins based on excluding-VAT amounts.
What's a realistic margin for combo events?
Activities can deliver 40-60% margin, catering 60-70%. Overall you'll typically land between 45-55% margin, depending on the mix of both components.
How do I handle no-shows with catering?
Set a minimum participant count and a deadline for final numbers in your contract. Build a 5-10% buffer into your cost price for exactly these risks.
Should I charge transport and setup separately?
Absolutely. Calculate transport and setup at cost plus 20-30% markup. These are real expenses that'll kill your profitability if you don't pass them through properly.
Can I use different margins for different activity types?
Yes, and you should. Specialized or unique activities justify higher margins than basic team building exercises. Price based on the actual value you're delivering.
How do I handle last-minute menu changes during combo events?
Charge a 25% premium for any changes within 48 hours of the event. Combo events already have tight logistics - changes create exponential complexity and risk.
