Beer sales at festivals and events generate solid profits, but only if you nail your margin calculations. Most food truck owners overlook hidden costs like tap losses, cooling expenses, and that 21% VAT rate. Here's how to calculate your actual beer margins for mobile operations.
Purchase price versus selling price fundamentals
Festival beer sales operate differently than restaurant service. You're handling tap systems, portable cooling, and typically paying higher wholesale prices for smaller volumes.
💡 Example:
You purchase a 50-liter Heineken keg for €85 (incl. VAT):
- Purchase price: €85 / 1.21 = €70.25 excl. VAT
- Per liter: €70.25 / 50 = €1.41 excl. VAT
- Per glass (0.25L): €1.41 × 0.25 = €0.35 excl. VAT
VAT on alcoholic beverages: 21%
This calculation step trips up many operators. Beer gets taxed at 21% VAT, not the 9% food rate.
⚠️ Important:
Always work with prices excluding VAT for margin calculations. Including VAT inflates your apparent margins.
Tap losses and foam calculations
Every pour creates waste. Factor in these losses for accurate cost pricing - it's the kind of thing you only learn after closing your first month at a loss.
- Foam and spillage: 5-10% of total keg volume
- First and last pours: rarely meet quality standards
- Line cleaning: particularly at daily startup
💡 Example tap loss:
50-liter keg with 8% tap loss:
- Usable beer: 50L × 0.92 = 46L
- Glass count: 46L / 0.25L = 184 glasses
- Cost per glass: €70.25 / 184 = €0.38 excl. VAT
Additional mobile service expenses
Food trucks and festival stands carry extra overhead that affects your beer pricing:
- Portable cooling: generator fuel or ice block costs
- Vendor fees: festival space rental charges
- Transportation: fuel costs and delivery time
- CO2 cartridges: tap system operation
- Disposable cups: if you're not using glassware
Complete margin calculations
Now you can determine your real profit margins. Use this pour cost formula (beer's equivalent of food cost):
Pour cost % = (Total costs per glass / Selling price excl. VAT) × 100
💡 Complete calculation:
Selling price: €4.50 incl. VAT (€3.72 excl. VAT)
- Beer costs: €0.38
- Cup: €0.05
- Additional expenses (cooling, transport): €0.12
- Total costs: €0.55
Pour cost: (€0.55 / €3.72) × 100 = 14.8%
Margin: €3.72 - €0.55 = €3.17 per glass
Beer margin benchmarks
Standard beer pour costs range from 18-25%. Festival pricing often allows for lower percentages due to premium selling prices.
- Excellent: 15-20% pour cost
- Good: 20-25% pour cost
- Acceptable: 25-30% pour cost
- Too high: above 30% pour cost
⚠️ Important:
Many festivals set maximum selling prices. Verify pricing limits beforehand, then work backwards to confirm profitability.
Beer variety margin differences
Different beer types yield varying profit levels. Specialty brews often deliver better margins than standard pilsner, but with slower turnover rates.
- Pilsner (Heineken, Grolsch): low wholesale cost, high volume sales
- Specialty beer: higher wholesale cost, premium selling prices
- Non-alcoholic: typically worse margins due to lower selling prices
Seasonal purchasing and timing
Your wholesale costs fluctuate based on purchase timing and volume. Strategic buying improves your margins significantly.
💡 Purchase tip:
Stock up on festival season beer during winter months. Suppliers typically offer discounts during low-demand periods.
How do you calculate beer margin? (step by step)
Calculate your actual purchase price per glass
Divide the keg price (excl. VAT) by the number of glasses you actually get from it. Factor in 5-10% tap loss for foam and spillage.
Add up all extra costs
Add costs for cups, cooling, CO2, transport, and stand fees. Divide these by the number of glasses you expect to sell.
Calculate your pour cost percentage
Divide your total costs per glass by your selling price (excl. 21% VAT) and multiply by 100. Aim for a maximum of 25% pour cost.
✨ Pro tip
Track your actual pour costs for 2 weeks straight, not just theoretical calculations. You'll often find your real waste percentage runs 2-3% higher than estimates, especially during busy festival rushes.

Frequently asked questions
Should I calculate 9% or 21% VAT on beer?
Alcoholic beverages always get taxed at 21% VAT, even at festivals. Calculate with 21% VAT, not the 9% food rate.
How much tap loss should I account for with beer?
Plan for 5-10% tap loss from foam, spillage, and line cleaning. A 50-liter keg typically yields 45-47 liters of sellable beer.
How do I factor in cooling and transport costs?
Calculate your total additional expenses (fuel, cooling, vendor fees) and divide by expected glass sales. Add this amount to your per-glass beer cost for accurate margins.
