How do I calculate the costs of a free-flow drinks package for groups?

📝 KitchenNmbrs · updated 14 Mar 2026

Most restaurant owners think they're making money on free-flow drinks packages until they actually crunch the numbers. The hidden costs pile up fast—overconsumption, waste, extra staff, and that 21% VAT rate many forget about. Here's how to calculate what these packages really cost you.

What's included in a free-flow drinks package?

A standard drinks package consists of various types of beverages that are served unlimited. The composition determines your costs:

  • Beer: Pilsner, craft beer, alcohol-free
  • Wine: White, red, rosé, sparkling
  • Soft drinks: Cola, juice, water
  • Hot beverages: Coffee, tea (optional)

Calculate your purchase costs per beverage type

Start with the purchase prices from your supplier. Convert everything to costs per glass:

💡 Example purchase prices:

  • Pilsner (30L keg): €45 = €0.30 per glass (0.2L)
  • House wine (3L bag-in-box): €12 = €1.00 per glass (0.15L)
  • Cola (1.5L bottle): €1.20 = €0.12 per glass (0.2L)
  • Coffee (1kg beans): €8 = €0.08 per cup

Don't forget additional costs for each beverage: CO2 for draft beer, lemon for wine, milk for coffee.

Account for overconsumption

With free-flow drinks, people consume way more than with individual orders. Calculate with these averages per person per 2 hours:

  • Beer: 3-4 glasses
  • Wine: 2-3 glasses
  • Soft drinks: 1-2 glasses
  • Coffee: 1-2 cups

⚠️ Note:

These are averages. An after-work drinks session (5:00 PM-7:00 PM) has different consumption than a Friday afternoon drinks (3:00 PM-6:00 PM). Adjust your calculation based on timing and target audience.

Calculate waste and leftovers

With free-flow, there's always waste—something most kitchen managers discover too late after their first big group booking. Account for these percentages on top of your consumption:

  • Draft beer: 5-10% (foam, discarding last remainder)
  • Wine: 10-15% (open bottles, tasting)
  • Soft drinks: 5% (leftovers, spills)

💡 Example calculation 50 people, 2 hours:

Expected consumption + waste:

  • Beer: 175 glasses × €0.30 = €52.50
  • Wine: 125 glasses × €1.00 = €125.00
  • Soft drinks: 75 glasses × €0.12 = €9.00
  • Coffee: 75 cups × €0.08 = €6.00

Total purchase costs: €192.50 = €3.85 per person

Add staff and other costs

Free-flow requires more staff than regular service. Calculate with:

  • Extra bartender: €25-30 per hour
  • Glasses and tableware: €0.50-1.00 per person
  • Cleaning afterwards: 30 minutes extra

Calculate your selling price

For a healthy margin, work with 20-25% pour cost (the beverage equivalent of food cost). This means your purchase costs should be a maximum of 25% of your selling price.

💡 Price calculation:

Total costs per person: €6.50 (€3.85 purchases + €2.65 staff/other)

At 25% pour cost: €6.50 ÷ 0.25 = €26.00 excl. VAT

Selling price: €26.00 × 1.21 = €31.46 incl. 21% VAT

⚠️ Note:

Alcoholic beverages fall under 21% VAT, not 9%. Even with packages that include soft drinks and coffee, 21% VAT applies if alcohol is the main component.

Vary your packages

Offer different levels to create more margin:

  • Basic: Pilsner, house wine, soft drinks (€25-30)
  • Premium: + craft beer, better wine (€35-40)
  • Deluxe: + prosecco, cocktails (€45-55)

A food cost calculator can automatically track the pour cost of each package and show you which packages generate the highest profits.

How do you calculate the costs of a free-flow drinks package?

1

Gather all purchase prices

Note the purchase prices of beer, wine, soft drinks and coffee from your supplier. Convert everything to costs per glass or cup. Don't forget additional costs: CO2, lemon, milk.

2

Calculate expected consumption per person

Calculate with an average of 3-4 glasses of beer, 2-3 glasses of wine and 1-2 soft drinks per person per 2 hours. Add 5-15% waste to this, depending on the beverage type.

3

Add staff and other costs

Calculate €2-3 per person for extra staff, glasses and cleaning. Divide your total costs by 0.25 for a healthy 25% pour cost and multiply by 1.21 for the price including 21% VAT.

✨ Pro tip

Recalculate your package costs every 3 months based on actual consumption data from past events. Most operators discover their wine waste is 20% higher than expected, significantly impacting profitability.

Frequently asked questions

What VAT applies to free-flow drinks packages?

21% VAT, because alcoholic beverages are the main component. Even if soft drinks and coffee are included in the package, the higher rate applies to the entire package.

How much do people drink on average at a free-flow drinks event?

Per person per 2 hours: 3-4 glasses of beer, 2-3 glasses of wine, 1-2 soft drinks. This depends on the time of day, target audience and duration of the event.

What is a healthy pour cost for drinks packages?

20-25% is standard. This means your purchase costs should be a maximum of a quarter of your selling price. Lower is possible, but becomes difficult with free-flow due to higher consumption.

Should I account for waste?

Yes, calculate 5-10% waste for beer, 10-15% for wine and 5% for soft drinks. With free-flow, there's always more waste than with individual orders.

Can I offer different package levels?

That's smart. Offer basic (pilsner, house wine), premium (+ craft beer) and deluxe (+ prosecco) options. Higher packages often have better margins because guests don't drink more, but pay more.

How do I handle groups with different drinking preferences?

Split your calculation by demographics—corporate events typically consume less alcohol than birthday parties. Track consumption patterns over 6 months to build accurate forecasting models.
