Beverage costs in catering can quickly spiral out of control without proper planning. An uncontrolled open bar setup can destroy your entire profit margin on an event. Here's how to calculate and manage beverage costs per person with precision.
What are beverage costs in catering?
Beverage costs in catering include all expenses for alcoholic and non-alcoholic drinks served during an event. With an open bar setup, customers pay a fixed rate per person, no matter how much guests actually consume.
This makes accurate cost calculation essential. Underestimate and you'll lose money. Overestimate and you'll price yourself out of jobs.
Calculate average beverage consumption per person
Average beverage consumption varies based on several key factors:
- Event duration: 4 hours = 4-5 drinks, 6 hours = 6-7 drinks
- Event type: Corporate events = lighter consumption, weddings = heavier
- Time of day: Lunch events = less alcohol, evening = more alcohol
- Guest demographics: Age and cultural background affect drinking patterns
💡 Example averages:
- Corporate reception (2 hours): 2-3 drinks per person
- Wedding celebration (6 hours): 6-8 drinks per person
- Birthday party (4 hours): 4-6 drinks per person
Calculate purchase price per drink
Determine your actual cost for each drink type. Important: always calculate excluding VAT for your base cost price.
💡 Example purchase prices:
- Beer (25cl): €0.80 cost
- Wine (15cl): €1.20 cost
- Soft drink (25cl): €0.40 cost
- Coffee/tea: €0.30 cost
For a mixed bar, calculate using a weighted average. Example: 40% beer, 30% wine, 20% soft drinks, 10% coffee/tea.
Weighted average: (0.40 × €0.80) + (0.30 × €1.20) + (0.20 × €0.40) + (0.10 × €0.30) = €0.77 per drink
Add extra costs
Don't overlook these additional expenses:
- Bartender wages: €15-25 per hour
- Supplies: Glassware, ice, garnishes
- Transport costs: Delivery to event location
- Licensing fees: Required permits for off-site alcohol service
⚠️ Note:
Alcoholic beverages carry 21% VAT, not 9%. This applies to catering services as well. Factor this into your final pricing.
Calculate total beverage costs per person
Apply this formula:
Beverage costs per person = (Average drinks consumed × Cost per drink) + (Additional costs / Total guests)
💡 Example calculation (wedding 80 guests, 6 hours):
- Average consumption: 7 drinks per person
- Cost per drink: €0.77
- Bartender: 6 hours × €20 = €120
- Supplies: €80
- Transport: €50
Calculation: (7 × €0.77) + ((€120 + €80 + €50) / 80) = €5.39 + €3.13 = €8.52 per person
Convert cost price to selling price
For healthy profitability, target 20-30% beverage costs. This means:
Selling price = Cost price / (Target cost percentage / 100)
At €8.52 cost and targeting 25% costs: €8.52 / 0.25 = €34.08 excl. VAT per person
Including 21% VAT: €34.08 × 1.21 = €41.24 per person
This is a pattern we see repeatedly in restaurant financials - beverage margins often make or break event profitability, so accurate costing is critical.
Monitor during the event
Track actual consumption to improve future estimates:
- Count empty bottles and cases
- Document remaining inventory
- Compare against your projections
- Update your consumption averages accordingly
💡 Pro tip for monitoring:
Photograph your inventory before and after each event. This makes consumption tracking much easier without tedious manual counting.
How do you calculate beverage costs per person? (step by step)
Estimate average beverage consumption
Determine how many drinks per person based on event duration, type of occasion, and target audience. Calculate approximately 1 drink per hour, but adjust for the situation.
Calculate weighted average purchase price
Figure out what each drink costs by multiplying percentages per drink type with purchase prices. Don't forget to include all beverages: beer, wine, soft drinks, coffee/tea.
Add extra costs and divide by number of persons
Add costs for bartender, materials, transport, and permits. Divide these total extra costs by the number of guests to get the costs per person.
Calculate total cost price per person
Multiply number of drinks by cost price per drink and add the extra costs per person. This is your total cost price per person.
Convert to selling price with margin
Divide your cost price by your desired cost percentage (usually 20-30%). Then add 21% VAT to get the final price for the customer.
✨ Pro tip
Track consumption patterns by event type over 6 months - corporate events typically see 40% less alcohol consumption than social celebrations. Use this data to create event-specific pricing tiers.

Frequently asked questions
What VAT rate applies to alcoholic beverages in catering?
Alcoholic beverages are taxed at 21% VAT, even in catering situations. Non-alcoholic beverages in catering fall under the reduced 9% VAT rate, same as food items.
How do I prevent excessive consumption at an open bar?
Set hourly limits, like maximum 2 alcoholic drinks per hour per guest. You can also switch to a drink ticket system after a certain time period. Some caterers implement a two-tier pricing system where premium spirits cost extra.
Should leftover beverages be factored into my pricing?
Always agree upfront whether leftovers belong to the client or return to you. Many caterers charge a 'leftover handling fee' if clients want to keep remaining alcohol. This protects against over-ordering by clients who think leftovers are 'free.'
