Only 23% of restaurants with sous-chefs actually calculate their true profitability beyond the base salary. Most owners focus on the €2,800 monthly wage but miss the real €4,346 total cost. Here's how to determine if this investment actually boosts your bottom line.
What does a sous-chef really cost?
A sous-chef runs much higher than the gross salary alone. You need to factor in every expense:
💡 Example: Total sous-chef costs
Sous-chef with €2,800 gross salary per month:
- Gross salary: €2,800
- Employer contributions (35%): €980
- Holiday pay: €233
- Year-end bonus: €233
- Work clothes/training: €100
Total per month: €4,346
How much extra revenue do you need to generate?
Breaking even on a sous-chef requires generating additional revenue. The calculation is straightforward:
Required extra revenue = Total sous-chef costs / Net profit margin %
💡 Example: Break-even calculation
Sous-chef costs €4,346/month, your net margin is 12%:
- Break-even revenue: €4,346 / 0.12 = €36,217/month
- That's €1,207 extra per day (30 days)
- At €35 average check: 35 extra covers/day
You need to serve 35 extra guests per day to break even
What does a sous-chef deliver?
A sous-chef creates value through multiple channels:
- More covers: Faster service, reduced guest wait times
- Higher quality: Consistent dishes, fewer returns
- Less waste: Improved planning and portion control
- You less in kitchen: Time for other responsibilities or rest
⚠️ Note:
A sous-chef only becomes profitable if you can actually serve more guests. If you're already running at half capacity, an extra cook won't solve the underlying issue.
Profitable sous-chef scenarios
Based on real restaurant P&L data, a sous-chef typically pays off in these situations:
- Waiting lists: You regularly turn guests away
- Long wait times: Dishes emerge from the kitchen too slowly
- Quality issues: Mistakes due to stress and rush
- You overworked: You're spending 70+ hours per week in the kitchen
💡 Example: ROI calculation
Restaurant currently does €45,000/month at 80% occupancy:
- With sous-chef: 95% occupancy possible
- Extra revenue: 15% of €45,000 = €6,750/month
- Sous-chef costs: €4,346/month
- Net benefit: €6,750 - €4,346 = €2,404/month
ROI: €2,404 / €4,346 = 55% return on investment
Alternatives to a sous-chef
Consider these more affordable options first:
- Part-time helper: Only during peak service hours
- Simplify menu: Faster preparation, reduced stress
- Optimize mise-en-place: Better prep equals faster service
- Temp worker: Flexible deployment, no fixed costs
Tools like KitchenNmbrs help you track exactly how much time each dish requires, so you can assess whether additional kitchen staff is truly necessary.
How do you calculate if a sous-chef is profitable? (step by step)
Calculate total monthly sous-chef costs
Add gross salary + employer contributions (35%) + holiday pay + 13th month + work clothes together. This gives you the real monthly investment.
Determine your net profit margin percentage
Divide your monthly net profit by your monthly revenue. You need this percentage to calculate how much extra revenue you need to generate.
Calculate required extra revenue
Divide the total sous-chef costs by your net profit margin. This is the extra revenue you need to generate at minimum to break even on the investment.
Convert to extra covers per day
Divide the required extra monthly revenue by 30 days and your average check amount. This tells you how many extra guests you need to serve per day.
Check if this is realistic
Can you actually serve that many extra guests? Do you have the space, are you already full, or do you regularly turn people away? If not, a sous-chef isn't profitable yet.
✨ Pro tip
Track your kitchen's ticket times for 2 weeks during peak service before hiring. If average ticket time exceeds 25 minutes, a sous-chef will likely pay for itself within 90 days.

Frequently asked questions
What are the real costs of a sous-chef per month?
Budget €3,500-€4,500 per month including employer contributions, holiday pay, and 13th month. The gross salary represents only 65% of total costs.
How much extra revenue do I need to break even on a sous-chef?
At €4,000 costs and 12% net margin, you need €33,333 extra revenue per month. That's roughly €1,100 extra per day.
Should I hire a sous-chef if my restaurant is already struggling with low occupancy?
No, if you're struggling to fill seats, an extra cook won't help. Focus on getting more guests first, then consider hiring additional staff.
Is a part-time helper better than a full-time sous-chef?
For many restaurants, part-time help during peak hours proves cheaper and more effective than a full-time sous-chef. Test first with temp workers before committing.
How do I measure if a sous-chef really adds value?
Compare your revenue, average wait time, and number of complaints before and after hiring. If these metrics don't improve significantly, the investment isn't profitable.
What occupancy rate makes a sous-chef most profitable?
Restaurants running at 75-85% capacity with regular waiting lists see the highest ROI from sous-chefs. Below 60% occupancy, focus on marketing instead of additional staff.
