Are you tracking just your liquor purchases while your bar bleeds money through hidden labor costs? Prime cost combines your beverage purchases and bar labor into one percentage of revenue. Most bar owners miss half the equation by ignoring staff costs entirely.
What is beverage prime cost?
Prime cost breaks down into two components:
- Beverage cost: what you pay for beer, wine, spirits and mixers
- Bar labor costs: salary of bartenders and servers (percentage allocated to the bar)
Combined, these give you prime cost. Most successful bars maintain prime costs between 45% and 55% of beverage revenue.
💡 Example:
Bar with €50,000 beverage revenue per month:
- Beverage purchases: €12,500 (25%)
- Bar labor costs: €11,000 (22%)
Prime cost: €23,500 = 47% of revenue
How do you calculate beverage cost?
Add up every purchase that goes behind your bar:
- Beer, wine, spirits
- Mixers (cola, tonic, juices)
- Garnishes (lemon, olives, cherries)
- Ice (if you purchase it)
⚠️ Note:
Calculate using beverage revenue excluding 21% VAT. Alcoholic beverages carry 21% VAT, not the 9% rate for food.
Beverage cost formula:
Beverage cost % = (Total beverage purchases / Beverage revenue excl. VAT) × 100
💡 Example calculation:
Month of February:
- Beverage revenue: €60,500 (incl. 21% VAT)
- Beverage revenue excl. VAT: €60,500 / 1.21 = €50,000
- Beverage purchases: €12,500
Beverage cost: €12,500 / €50,000 × 100 = 25%
How do you calculate bar labor costs?
Bar labor represents the slice of your total payroll dedicated to beverage service. You'll need to split your personnel costs between bar and kitchen operations.
Most establishments use these allocations:
- Pure bar: 100% to beverages
- Restaurant with bar: 60-70% to food, 30-40% to beverages
- Café with kitchen: 50-60% to beverages, 40-50% to food
💡 Example restaurant:
Restaurant with 70% food, 30% beverage revenue:
- Total labor costs: €25,000
- 35% goes to bar: €8,750
- Beverage revenue excl. VAT: €30,000
Bar labor %: €8,750 / €30,000 × 100 = 29%
Prime cost calculation
Add both percentages:
Prime cost % = Beverage cost % + Bar labor %
💡 Total example:
Restaurant from previous examples:
- Beverage cost: 25%
- Bar labor: 29%
Prime cost: 25% + 29% = 54%
A 54% prime cost runs high. Most profitable bars target 45-50%.
What are good benchmarks?
Prime cost targets vary by establishment type:
- Cocktail bar: 40-50% (higher beverage cost from premium spirits)
- Café/pub: 45-55% (beer-heavy sales, thinner margins)
- Restaurant bar: 45-50% (diverse beverage mix)
- Wine bar: 35-45% (strong wine margins)
⚠️ Note:
These serve as guidelines only. Your location, concept and pricing strategy determine what's achievable for your specific bar.
How do you improve your prime cost?
Prime costs above 55% signal trouble. Focus on these areas:
- Raise your prices: a 10% price increase directly reduces your prime cost
- Check your portions: are you pouring too generously per glass?
- Negotiate with suppliers: especially for higher volumes
- Optimize your staffing: avoid overstaffing during slow periods
A pattern we see repeatedly in restaurant financials shows that bars using tracking systems can automatically monitor beverage cost per product, revealing which drinks generate the highest and lowest profits. Tools like KitchenNmbrs make this analysis automatic rather than manual.
How do you calculate beverage prime cost? (step by step)
Calculate your beverage cost percentage
Add up all your beverage purchase costs (beer, wine, spirits, mixers, garnishes). Divide this by your beverage revenue excluding 21% VAT and multiply by 100.
Calculate your bar labor costs percentage
Determine what portion of your personnel costs goes to the bar (usually 30-40% in restaurants). Divide this by your beverage revenue excluding VAT and multiply by 100.
Add both percentages together
Prime cost = beverage cost % + bar labor %. A healthy prime cost falls between 45-55% of your beverage revenue, depending on your type of establishment.
✨ Pro tip
Track your prime cost weekly for 8 weeks straight, then identify your highest-volume day. That single day often represents 25-30% of your weekly beverage sales and reveals your true operational efficiency.

Frequently asked questions
Should I include VAT in my prime cost calculation?
No, always calculate using revenue excluding VAT. Alcoholic beverages carry 21% VAT. Divide your revenue by 1.21 to get the pre-tax amount.
How do I determine what portion of labor costs goes to the bar?
Base it on your revenue split. If beverages generate 30% of revenue, allocate roughly 35% of labor costs to the bar. Pure bars assign 100% of labor costs to beverages.
What's a realistic prime cost target for my café?
Cafés and pubs should aim for 45-55%. Cocktail bars often achieve 40-50% due to better mixed drink margins, while wine bars frequently hit 35-45%.
How frequently should I calculate prime cost?
Monthly calculations reveal trends effectively. Weekly tracking helps you adjust faster when numbers drift off target.
What if my prime cost exceeds 60%?
You're likely losing money on beverage sales. Start by auditing your portions and pricing structure. A 10-15% price increase alone often restores profitability.
Can seasonal variations affect my prime cost benchmarks?
Absolutely. Summer months might show lower labor percentages due to higher volume, while winter could push prime costs up. Track these patterns annually to set realistic monthly targets.
Should I calculate prime cost differently for happy hour periods?
Yes, happy hour pricing typically pushes prime costs higher temporarily. Calculate these periods separately to understand their true profitability impact on your overall beverage program.
