Most restaurant owners discover their group drinks cost 40% more than expected after the first busy weekend. You calculate the main ingredients but forget garnish, ice, and labor costs. Here's how to get the real cost per glass.
Gather all ingredients and quantities
For accurate cost calculation, you need every ingredient that goes into your punch. Even the smallest additions count.
💡 Example: Fruity welcome punch (10 glasses):
- 1 liter white wine: €8.00
- 0.5 liter orange juice: €1.50
- 0.3 liter cranberry juice: €2.00
- 2 oranges (slices): €1.20
- Fresh mint: €0.80
- Ice (2 kg): €1.00
Total ingredients: €14.50
Calculate the cost per glass
Divide total ingredient costs by the number of glasses you can make from this amount.
Formula: Cost per glass = Total ingredient costs ÷ Number of glasses
💡 Calculation:
€14.50 ÷ 10 glasses = €1.45 per glass
This is your pure ingredient cost.
Include labor costs and overhead
Group drinks involve more work than regular orders. Prep time, serving and cleanup cost time and money.
- Prep time: 15-20 minutes for 10 glasses
- Serving: 5 minutes
- Cleanup and washing: 10 minutes
💡 Labor cost calculation:
Total time: 35 minutes
Bartender hourly rate: €18.00
Labor costs: (35 ÷ 60) × €18.00 = €10.50
Per glass: €10.50 ÷ 10 = €1.05
Determine your selling price and margin
Add ingredients and labor costs for your total cost. Based on that, you determine your selling price.
💡 Total cost:
- Ingredients: €1.45
- Labor: €1.05
- Total: €2.50 per glass
At a selling price of €6.00 (incl. 21% VAT) you have:
€6.00 ÷ 1.21 = €4.96 excl. VAT
Pour cost: (€1.45 ÷ €4.96) × 100 = 29.2%
⚠️ Note:
Alcoholic drinks fall under 21% VAT, not 9%. Always calculate excl. VAT for your cost calculation.
Special considerations for group drinks
Punch and welcome drinks have specific cost items you shouldn't forget - something most kitchen managers discover too late during their first catering event.
- Waste: With large quantities there's often some left over
- Presentation: Nice glasses, decoration, serving pitchers
- Timing: Often needs preparation in advance, takes fridge space
- Variety: Guests sometimes want an alcohol-free version
💡 Waste calculation:
Calculate 10-15% extra ingredients for waste and tasting.
€14.50 × 1.15 = €16.68 total costs
€16.68 ÷ 10 glasses = €1.67 per glass (instead of €1.45)
Include alcohol-free variant
Often 20-30% of your guests want an alcohol-free version. Plan this in advance in your cost calculation.
💡 Alcohol-free version (3 of the 10 glasses):
- 0.7 liter white wine: €5.60
- 0.3 liter extra juice: €1.80
- Other ingredients: €4.10
New cost: €11.50 ÷ 10 = €1.15 per glass
Digital cost calculation
For complex drinks with many ingredients, manual calculation becomes difficult. Tools like KitchenNmbrs can track all ingredients, quantities and prices.
- Automatic cost calculation per glass
- Easy to adjust when supplier prices increase
- Compare different variants (alcoholic/alcohol-free)
- Pour cost percentage visible immediately
How do you calculate cost per glass? (step by step)
Make an ingredients list
Write down all ingredients with exact quantities and prices. Don't forget garnish, ice and decoration. Add everything up for your total ingredient costs.
Divide by number of glasses
Divide your total ingredient costs by the number of glasses you can make from this amount. This gives you the pure ingredient cost per glass.
Include labor costs
Calculate how much time prep, serving and cleanup takes. Multiply by your hourly rate and divide by number of glasses for labor cost per glass.
Determine selling price and margin
Add ingredients and labor costs together. Calculate your pour cost percentage by dividing ingredient costs by selling price excl. 21% VAT.

Frequently asked questions
How do I account for waste with large quantities of punch?
Calculate 10-15% extra ingredients for waste, tasting and unforeseen situations. This prevents your cost from being too low and protects your margins.
What's a good pour cost for group drinks?
For punch and welcome drinks, 25-35% pour cost is standard. This is higher than regular orders due to extra prep time and presentation requirements.
Do I need to calculate labor costs separately for punch?
Yes, punch takes more prep time than regular orders. Include 15-20 minutes prep plus serving and cleanup time in your cost calculation.
Can I charge the same price for alcoholic and alcohol-free versions?
Usually yes, because the alcohol-free version contains more juice to compensate. Calculate both variants to be sure of your margin on each.
