87% of restaurant owners underestimate the true cost difference between solo operations and hiring staff. This critical decision shapes your entire profit structure. Most owners rely on gut instinct, but the numbers reveal surprising truths about profitability.
The real cost of staff
That €12-per-hour employee actually costs you €18-20 per hour. Employer contributions, sick leave, and turnover add up fast. Then there's scheduling, training, and endless paperwork eating your time.
💡 Example:
Kitchen assistant €12/hour, 30 hours per week:
- Gross salary: €1,560/month
- Employer contributions (25%): €390/month
- Sick leave (5%): €78/month
- Training and administration: €100/month
Real costs: €2,128/month
What does your own time cost?
Your hours aren't free, even without a paycheck. Every minute you're prepping vegetables is time you're not growing your business. Calculate your entrepreneurial hourly rate and factor it into your costs.
⚠️ Watch out:
Most entrepreneurs ignore their own time value. This makes solo work appear cheaper, but you're missing the opportunity cost of not focusing on revenue-generating activities.
Compare productivity and revenue
Staff means more covers and longer hours. But does the extra revenue justify the costs? From years of working in professional kitchens, I've seen owners shocked by how much additional business one good team member can generate.
💡 Example:
Restaurant with 40 covers per evening:
- Alone: 6 days open, 240 covers/week
- With staff: 7 days open, 280 covers/week
- Extra revenue: 40 × €28 = €1,120/week
- Extra staff costs: €532/week
Net benefit: €588/week
Factor in quality and consistency
Solo operations are fragile. You get sick? Revenue stops. Peak rush hits? Guests wait forever. Staff provides backup, but training takes months to achieve consistency.
- Illness losses: how much revenue vanishes per sick day?
- Vacation coverage: close entirely or hire expensive temps?
- Rush periods: how many frustrated guests walk out?
- Standards: can anyone else execute your dishes properly?
The break-even calculation
Total up every cost and weigh against staff-enabled revenue gains. Here's your formula: Break-even point = Extra staff costs / (Average bill × Extra covers)
💡 Example:
Extra staff costs €2,128/month at average bill €25:
- Break-even: €2,128 ÷ €25 = 85 extra covers/month
- That's roughly 3 extra guests per day
Achievable? Then hiring staff makes financial sense
How do you calculate the financial difference? (step by step)
Calculate the real staff costs
Add to the gross salary: employer contributions (25%), sick leave (5%), training and administration (€100-200/month). These are your real costs per employee.
Determine your own hourly rate
Calculate what your time is worth as an entrepreneur. Take your desired annual income divided by 1,800 working hours. This is the opportunity cost of your own time.
Measure extra revenue with staff
Calculate how many more covers you can serve with help. Multiply this by your average bill to determine the extra revenue.
Subtract costs from extra revenue
Extra revenue minus extra staff costs = net benefit. Is this positive? Then hiring staff makes financial sense. Don't forget to factor in continuity and quality.
✨ Pro tip
Test your numbers with a 2-week trial employee during your busiest period. Track exactly how many additional covers you serve - most owners discover they need just 4-5 extra guests daily to break even.

Frequently asked questions
What are the hidden costs beyond an employee's hourly wage?
Beyond the €12 hourly wage, add 25% employer contributions, 5% sick leave coverage, plus training time and administrative overhead. Your real cost hits €18-20 per productive hour.
How do I calculate my own value as an entrepreneur per hour?
Divide your target annual income by 1,800 working hours. At €50,000 yearly, that's €28 per hour you're sacrificing by doing kitchen work instead of business development.
What's the minimum extra revenue needed to justify hiring staff?
For a €2,000 monthly employee cost, you need roughly 80 additional covers monthly at €25 average spend. That breaks down to just 3 extra guests daily.
How do I account for my own sick days and vacation time?
Calculate lost revenue for closure days. At €800 daily revenue, one sick day costs €800 plus potential customer loss. Factor 10-15 closure days annually into your solo operation costs.
Should I hire full-time or part-time staff first?
Start part-time during peak hours to test the revenue impact. You'll see if extra covers justify costs before committing to full-time wages and benefits.
How do I measure staff productivity versus my own output?
Track covers per hour and order accuracy. Good staff often handle 15-20% more volume while maintaining quality, but require 2-3 months training investment.
What if my staff member quits after expensive training?
Budget €500-800 replacement costs per position annually. High-turnover roles need this factored into your break-even calculations from day one.
