Picture this: you're budgeting for summer staff and realize that €14/hour worker actually costs €18.90/hour. Seasonal labor includes employer contributions, holiday pay, and recruitment expenses that many operators overlook. Understanding these hidden costs prevents budget surprises during your busiest months.
What's included in the labor cost of seasonal workers?
Labor cost extends far beyond the gross salary. Seasonal workers bring these additional expenses:
- Gross salary: The agreed hourly or monthly rate
- Employer contributions: Social premiums, approximately 25-30% of gross salary
- Holiday pay: 8% of gross annual salary (applies to temporary contracts too)
- Recruitment costs: Job postings, temp agency fees, candidate screening
- Onboarding costs: Training time, supervision during initial weeks
💡 Example:
Seasonal worker for 4 months summer (May-August), 32 hours per week:
- Gross salary: €14/hour × 32 hours × 17 weeks = €7,616
- Employer contributions (27%): €2,056
- Holiday pay (8%): €609
- Recruitment and onboarding: €500
Total labor cost: €10,781
Calculate the total labor cost per month
Seasonal workers require period-based calculations rather than annual projections. Use this formula:
Total labor cost = (Gross salary + Employer contributions + Holiday pay) + One-time costs
Employer contributions fluctuate between 25-30% of gross salary. The exact percentage depends on worker age and contract structure.
⚠️ Note:
Seasonal workers earn holiday pay regardless of contract duration. This oversight represents one of the most common blind spots in kitchen management cost planning.
Impact on your food cost and break-even
Additional summer staff increases fixed costs, requiring higher revenue to maintain profitability:
- With €10,781 extra labor cost per season, you'll need €2,695 additional monthly revenue
- This calculation assumes labor costs represent 40% of revenue (hospitality standard)
- At €25 average check, that translates to 108 extra covers monthly
💡 Example:
Restaurant with baseline revenue €20,000/month:
- Extra labor cost season: €2,695/month
- Required additional revenue: €2,695 ÷ 0.40 = €6,738/month
- At €25/cover: 270 extra covers per month
- That's 9 additional covers daily
Realistic during peak summer, but requires strategic planning.
Temp workers vs. your own staff
Temporary workers appear costlier hourly but can offer better value for short-term needs:
- Temp worker: €18-22/hour all-inclusive, no additional costs
- Direct seasonal hire: €14/hour + 35% employer contributions = €18.90/hour
- Temp worker benefits: Zero recruitment expenses, flexible scaling options
- Direct hire benefits: Smoother integration, stronger commitment to operations
Registration and administration
Seasonal workers create additional administrative requirements. Monitor these elements:
- Weekly hours worked (for payroll and holiday pay calculations)
- Monthly total labor costs (for P&L tracking)
- Productivity metrics: revenue increase generated by additional staff
Systems like KitchenNmbrs allow you to monitor how extra staff affects your margins. This data helps optimize decisions for future seasons.
How do you calculate the labor cost of a seasonal worker? (step by step)
Calculate the gross salary for the entire period
Multiply hourly rate × hours per week × number of weeks. For a summer season from May-August, count 17 weeks. At 32 hours per week and €14/hour: €14 × 32 × 17 = €7,616 gross salary.
Add employer contributions and holiday pay
Employer contributions are approximately 27% of gross salary. Holiday pay is 8% of gross salary. At €7,616 gross: €2,056 employer contributions + €609 holiday pay = €2,665 extra costs.
Add one-time costs
Include recruitment, screening, and onboarding costs. This usually costs €300-500 per seasonal worker. Total labor cost becomes: €7,616 + €2,665 + €500 = €10,781 for the entire season.
✨ Pro tip
Start recruiting seasonal workers by February to secure better candidates and negotiate rates 15-20% lower than peak season hiring. Early planning saves roughly €400-600 per seasonal hire.

Frequently asked questions
Do I have to pay holiday pay to a seasonal worker for 4 months?
Yes, seasonal workers earn holiday pay regardless of contract length. This equals 8% of gross salary, even for contracts under one year. Factor this into your total cost calculations.
Are temp workers cheaper than hiring seasonal staff directly?
Often yes for shorter periods. Temp workers cost €18-22/hour all-inclusive without recruitment or training expenses. For seasons lasting 3+ months, direct hires usually prove more economical.
How much extra revenue do I need to cover a seasonal worker?
Divide monthly labor cost by your labor percentage. With 40% labor costs and €2,700 additional monthly labor expense, you need €6,750 extra monthly revenue.
Can I hire seasonal workers on zero-hour contracts?
Yes, but availability becomes uncertain. For busy summer periods, fixed contracts of 20-32 hours weekly provide better reliability, despite slightly higher costs.
How do I calculate employer contributions exactly?
Employer contributions include social premiums totaling approximately 25-30% of gross salary. Most hospitality operations can use 27% as a baseline. Consult your accountant for precise percentages based on your situation.
What's the minimum contract duration for seasonal workers to be worthwhile?
Generally 6-8 weeks minimum to justify recruitment and training costs. Shorter periods favor temp workers, while 3+ month seasons make direct hiring more cost-effective.
