Nearly 40% of catering businesses lose money on their first corporate events because they underestimate hidden costs. Sinterklaas party catering works differently than your regular restaurant - you're charging per person while juggling transport, setup, and the dreaded no-show risk. Here's how to calculate a margin that actually keeps you profitable.
What makes catering different from a restaurant?
Catering flips your entire cost structure upside down. You're not charging per dish anymore - it's per person, and that changes everything. Transport costs hit your bottom line, setup eats into your time, and you're gambling on attendance numbers that can shift at the last minute.
💡 Example:
Sinterklaas party for 50 people, price €25 per person:
- Food & drink costs: €12 per person
- Staff on-site: €200 total
- Transport and setup: €100 total
- Total revenue: €1,250
Margin: €1,250 - €600 - €300 = €350 (28%)
The hidden costs of catering
Here's where most caterers get burned - the costs you never see coming until they're eating your profits:
- Transport: fuel, wear and tear, parking fees
- Extra staff: service on-site, often at overtime rates
- Materials: warming trays, dishes, glasses you take with you
- Setup time: your staff spends 2 hours setting up for a 1-hour party
- No-show risk: company says 50 people, only 35 show up
⚠️ Note:
Always calculate with the price excl. VAT. A Sinterklaas party of €25 incl. VAT is €22.94 excl. VAT (€25 / 1.09).
Standard margins for catering
Catering margins don't follow restaurant rules. Your cost structure's completely different, and your percentages need to reflect that reality:
- Food & drink costs: 45-55% of revenue (higher than restaurant due to extra logistics)
- Staff costs: 20-30% of revenue (including travel time and setup)
- Other costs: 5-10% (transport, materials, risk)
- Net margin: 15-30% (depending on size and complexity)
💡 Example calculation:
Sinterklaas party 40 people at €30 excl. VAT:
- Revenue: €1,200
- Food & drink (50%): €600
- Staff (25%): €300
- Transport & materials (8%): €96
Net margin: €204 (17%)
How do you prevent running at a loss?
This is the kind of thing you only learn after closing your first month at a loss - being optimistic kills catering margins faster than anything else. Here's how to protect yourself:
- Minimum number of guests: agree in advance that you calculate for at least 80% of the stated number
- Include travel time: if you're traveling for 2 hours, factor that into your staff costs
- Complexity surcharge: buffet is cheaper than a served party
- Seasonal factor: December is more expensive due to busy season and overtime rates
💡 Practical example:
You calculate for 50 people but only 40 show up:
- Planned revenue: €1,250
- Actual revenue: €1,000
- Fixed costs remain the same: €300
Result: your margin drops from 28% to 12%
Digitally tracking catering margins
Managing multiple events gets messy fast, and you'll lose track of which types actually make money. Tools like KitchenNmbrs let you record actual costs and margins per event type, so you can price more accurately next time instead of guessing.
How do you calculate the margin on catering? (step by step)
Calculate all food & drink costs per person
Add up what all the snacks, drinks and garnishes cost. Calculate with 10% extra for waste and no-shows. Divide by the number of people for cost per person.
Calculate all extra costs
Add up: transport, staff on-site (including travel time), materials, setup time. These costs are the same whether 30 or 50 people attend.
Calculate your minimum selling price
Divide all costs by number of people for cost price per person. For 20% margin: divide by 0.80. For 25% margin: divide by 0.75. This is your minimum price excl. VAT.
✨ Pro tip
Track your actual food waste on Sinterklaas events for 3 months - Dutch companies typically overestimate attendance by 15% in December, but you can adjust your portions accordingly and boost margins by 4-6%.

Frequently asked questions
What if fewer people show up than indicated?
Agree in advance on a minimum of 80% of the stated number. Your fixed costs like transport and staff don't change, so fewer guests means your margin takes a direct hit.
Should I include VAT in my margin calculation?
Never calculate margins with VAT included. A €25 party including VAT is actually €22.94 excluding VAT, and that's your real revenue number.
How do I factor in travel time and setup?
Add up every hour your staff is away from base: travel there, setup, event, breakdown, travel back. Multiply by your full hourly rate including employer taxes. Setup time often doubles your labor costs.
What happens if I quote too low on a Sinterklaas event?
You'll eat the loss because catering contracts are fixed-price. Make a checklist of every possible cost and calculate pessimistically - losing a job beats losing money on it.
