Most bars run smoothly during peak hours but struggle during quiet periods. Bar owners often don't realize they're losing money every hour they can't hit their minimum beverage revenue threshold. Here's exactly how to calculate the break-even point for your staff costs.
Why this calculation matters for your bottom line
Staff wages represent your second-largest expense after inventory. Without knowing your revenue threshold, you're essentially guessing whether each shift turns a profit. During slow periods, many establishments unknowingly operate at a loss - a mistake that costs the average restaurant EUR 200-400 per month in unnecessary labor expenses.
⚠️ Note:
Always calculate with your actual hourly wage including employer contributions. Gross salary isn't enough - there's another 25-35% in costs on top.
The basic formula for break-even beverage revenue
The formula is straightforward:
Minimum beverage revenue per hour = Total staff costs per hour / Average gross margin %
Where gross margin = (Selling price - Cost price) / Selling price × 100
💡 Example calculation:
You have 1 bartender at €16/hour (incl. employer contributions: €21/hour)
- Beer: selling price €3.50 (excl. 21% VAT = €2.89), cost €0.80 → margin 72%
- Wine: selling price €6.00 (excl. VAT = €4.96), cost €1.50 → margin 70%
- Spirits: selling price €8.00 (excl. VAT = €6.61), cost €1.20 → margin 82%
Average margin: 75%
Minimum revenue: €21 / 0.75 = €28 per hour
Calculate true staff costs
Most business owners underestimate their real labor expenses. They focus on gross wages but miss the bigger picture:
- Gross salary: Base hourly rate on payslips
- Employer contributions: 25-35% additional (pension, unemployment, insurance)
- Holiday pay: 8% of annual compensation
- Sick leave coverage: Typically 4-6% extra
💡 Calculation example real costs:
Bartender €14/hour gross
- Gross salary: €14.00
- Employer contributions (30%): €4.20
- Holiday pay (8%): €1.12
- Sick leave buffer (5%): €0.70
Real costs: €20.02 per hour
Calculate average margin on beverages
You'll need your weighted average margin based on actual sales. Different beverages deliver different profitability:
- Beer: 70-80% margin
- Wine per glass: 65-75% margin
- Spirits/cocktails: 75-85% margin
- Soft drinks: 85-90% margin
Pull your POS data from the past month and weight these margins by actual volume sold.
⚠️ Note:
Always calculate with prices excl. VAT. Alcoholic beverages have 21% VAT, so €5.00 incl. VAT = €4.13 excl. VAT.
Apply this across different shifts
Your staffing needs change throughout the day, so your break-even points shift too:
- Lunch service (12-15h): Minimal staffing, lower expectations
- Happy hour (17-19h): 1-2 staff, higher turnover potential
- Peak evening (20-24h): Full team, maximum revenue hours
- Weekend daytime: Depends on your concept and location
💡 Planning example:
Friday evening, 2 bartenders (€40/hour total), average margin 78%
- Break-even revenue: €40 / 0.78 = €51 per hour
- That's roughly 15 beers or 10 cocktails per hour
- With 20 guests = average €2.55 per guest per hour
Below €51/hour you lose money on staff
Account for seasonal fluctuations
Revenue patterns change throughout the year. Plan your staffing around these realities:
- January/February: Typically 30-40% revenue drop
- Weekday evenings: Often require skeleton crews only
- Holiday periods: Varies dramatically by location
Consider reduced hours or skeleton staffing during periods where break-even revenue becomes unrealistic. Tools like a food cost calculator can help track these patterns over time.
How do you calculate your minimum beverage revenue? (step by step)
Calculate your real staff costs per hour
Add 30-35% to the gross salary for employer contributions, holiday pay and sick leave. A bartender at €14/hour gross actually costs you about €20/hour.
Determine your average margin on beverages
Look at your till data and calculate the margin per drink type. Weight this by sales volume. Beer 75%, wine 70%, spirits 80% gives for example an average of 75%.
Calculate your break-even revenue per hour
Divide your total staff costs per hour by your average margin. With €20/hour staff and 75% margin you need €26.67 revenue per hour to break even.
✨ Pro tip
Track your actual hourly beverage revenue against your break-even threshold every week. Most bars discover they're losing €15-25 per hour during at least 3-4 shifts weekly without realizing it.

Frequently asked questions
Should I include VAT in my revenue calculation?
No, always calculate with amounts excl. VAT. Alcoholic beverages have 21% VAT, so €5.00 on the menu is €4.13 excl. VAT for your calculation.
What if my break-even revenue seems unrealistically high?
You're overstaffed for the expected volume. Consider reducing staff during those hours or temporarily closing during very quiet periods. The math doesn't lie - you can't afford to operate below break-even.
How do I handle mixed shifts with bartenders at different wage levels?
Add up the total hourly cost for all staff working that shift. Two bartenders earning €18 and €22 per hour respectively would create a €40/hour total labor cost for your calculation.
