Picture this: your hotel ballroom books an 80-guest wedding, and six months later you realize you barely broke even. Wedding banquets involve way more moving parts than regular restaurant service - from extra staffing to floral arrangements to room setup costs. Most venues underestimate these hidden expenses and end up with razor-thin margins.
All cost items for a wedding banquet
Wedding banquets eat up costs you'd never see on a typical Saturday night. Miss even one category and your profit vanishes.
💡 Example: Wedding 80 guests
Three-course menu at €65 per person:
- Food & beverage: €28 per person
- Extra service: €12 per person
- Décor & styling: €8 per person
- Room & coordination: €7 per person
- Contingency: €3 per person
Total costs: €58 per person → Margin: €7 (10.8%)
Calculate food & beverage cost price
Start with ingredients and drinks - but banquet menus typically feature pricier items than your everyday offerings.
- Appetizer: Count every garnish, sauce, and micro-green
- Main course: Weigh portions exactly - no eyeballing expensive proteins
- Dessert: Include decorative elements and specialty ingredients
- Beverages: Welcome drinks, dinner wine, coffee service - track it all
Typical banquet food costs run 25-35% of menu price. Premium ingredients can push this to 40%.
⚠️ Note:
Always work with prices excluding VAT. €65 including 9% VAT equals €59.63 excluding VAT. Base your percentages on that net figure.
Extra service and staff
Banquets demand more hands than regular service. You're orchestrating setup, dinner service, and breakdown - often simultaneously.
- Setup: 2-3 hours pre-event for table arrangements and décor placement
- Service: Higher staff-to-guest ratio (1:12 vs. normal 1:20)
- Breakdown: 1-2 hours post-event cleanup
- Coordination: Dedicated person managing timeline and couple communication
Budget €10-15 per person in additional labor beyond standard food service costs.
Décor, styling and extra materials
Couples want Instagram-worthy moments. That visual appeal requires investment and labor.
💡 Example: Décor costs
- Specialty linens and napkins: €3 per person
- Centerpieces and florals: €4 per person
- Premium glassware and flatware: €1 per person
- Ambient lighting: €2 per person
Total décor: €10 per person
Create tiered packages (essential, enhanced, luxury) so you're not reinventing pricing for each event.
Room rental and overhead
Your ballroom has value - even if you own it. That space can't generate other revenue during the event.
- Opportunity cost: Revenue you'd earn from regular hotel guests
- Deep cleaning: Pre and post-event sanitation
- Climate control: Extended HVAC operation
- Event insurance: Additional liability coverage
Factor €5-10 per person for facility and overhead expenses.
Risks and unforeseen costs
Based on real restaurant P&L data, weddings always include surprise expenses. Smart operators build cushions into their pricing.
⚠️ Note:
Last-minute modifications happen at 90% of weddings. Include a 5-10% buffer for guest count changes, special requests, or unexpected complications.
Profitable margins for banquets
Banquets can operate on slimmer margins than à la carte since you have guaranteed covers and reduced waste.
- Survival margin: 15-20% (any less risks losses from complications)
- Sustainable margin: 20-30%
- Premium margin: 30%+ (exclusive venues or unique experiences)
Consider this: one 80-guest wedding equals the revenue of 4-5 regular service nights. That volume deserves protection.
How do you calculate the margin on a wedding banquet? (step by step)
Calculate food & beverage costs per person
Add up all ingredients for the complete menu. Don't forget aperitif, wine, coffee and petit fours. Divide by number of guests for cost price per person.
Calculate extra staff and service costs
Add up: extra setup hours, more intensive service during event, breakdown and coordination. Calculate €10-15 per person in extra staff costs.
Add décor, room and buffer
Add together décor costs (€5-10 per person), room rental/overhead (€5-10 per person) and a 5-10% buffer for unforeseen costs.
Calculate total cost price and desired margin
Add up all costs for your total cost price per person. For a healthy margin, calculate: cost price / 0.75 (= 25% margin) for your minimum selling price excl. VAT.
✨ Pro tip
Build a banquet costing spreadsheet with all fixed per-person costs built in. For an 80-guest wedding, allocate exactly 3.5 hours for final cost review and approval - this prevents last-minute pricing errors that can kill your margin.

Frequently asked questions
What's a realistic profit margin on wedding banquets?
Aim for 20-30% margins on wedding events. Anything under 15% leaves you vulnerable to unexpected costs. Premium venues with unique offerings can command 30%+ margins.
Should I calculate margins including or excluding VAT?
Always work excluding VAT. A €65 menu price with 9% VAT equals €59.63 net. Base all your cost percentages on that net figure to avoid confusion.
How much extra staffing do banquets require?
Plan for 1 server per 12 guests instead of your normal 1:20 ratio. Add dedicated staff for setup, breakdown, and event coordination. Budget €10-15 per person total for additional labor.
How should I structure décor pricing?
Create three fixed packages: basic (€5-7 per person), premium (€8-12 per person), and luxury (€15+ per person). This eliminates custom calculations for each event and speeds up quoting.
What contingency should I build into wedding pricing?
Include a 5-10% buffer in your base costs for last-minute changes and unexpected expenses. Nearly every wedding involves some modification from the original plan.
How do I account for room rental in my own venue?
Calculate opportunity cost - what revenue would that space generate from regular guests? Add deep cleaning, extended utilities, and event insurance. Budget €5-10 per person for facility costs.
Can banquet margins be lower than restaurant margins?
Yes, banquets can operate on slightly lower margins due to guaranteed guest counts and reduced waste. However, never go below 15% - the complexity and risk aren't worth razor-thin profits.
