How do I calculate total personnel costs including social contributions per month?

📝 KitchenNmbrs · updated 13 Mar 2026

Personnel costs typically exceed gross salaries by 40-60% once you factor in social contributions and benefits. Most restaurant owners underestimate these hidden expenses. Understanding your true monthly personnel costs prevents budget surprises and helps you price your menu correctly.

What are total personnel costs?

Your total personnel costs include the gross salary plus every additional expense you pay as an employer. These are the social contributions, premiums and allowances that stack on top of base wages.

The components of personnel costs

Your personnel costs break down into several parts:

  • Gross salary: The salary your employee receives
  • Employer premium unemployment insurance (WW): Approximately 2.9% of gross salary
  • Employer premium disability insurance (WGA): Approximately 0.7% of gross salary
  • Employer premium health insurance (ZVW): Approximately 6.9% of gross salary
  • Holiday pay: Minimum 8% of gross salary
  • Employer pension premium: Varies per pension scheme

💡 Example:

Employee with gross salary €2,500 per month:

  • Gross salary: €2,500
  • Social contributions (approx. 10.5%): €263
  • Holiday pay (8%): €200
  • Employer pension premium (5%): €125

Total monthly costs: €3,088

Social contributions percentage 2024

Employer premiums shift annually. For 2024, the standard percentages are:

  • Unemployment insurance premium: 2.9% (unemployment act)
  • Disability insurance premium: 0.7% (work disability)
  • Health insurance premium: 6.9% (health insurance)
  • Total social contributions: Approximately 10.5%

⚠️ Note:

These percentages fluctuate each year. Always verify current percentages with the Tax Authority or your accounting office.

Holiday pay and other allowances

Beyond social contributions, you've got other mandatory costs:

  • Holiday pay: Minimum 8% of annual salary
  • 13th month: If included in your collective labor agreement
  • Year-end bonus: If agreed upon
  • Travel allowance: Often €0.19 per kilometer

Calculation with restaurant example

Here's how you calculate total costs for a chef with €2,800 gross salary:

💡 Complete example:

Chef with €2,800 gross salary per month:

  • Gross salary: €2,800
  • Social contributions (10.5%): €294
  • Holiday pay (8% of annual salary): €187
  • Employer pension premium (6%): €168
  • Travel costs (€50/month): €50

Total monthly costs: €3,499

That's 25% higher than the gross salary!

Hospitality collective labor agreement and extra costs

In hospitality, there are often additional arrangements:

  • Shift allowance: For evening and weekend work
  • Irregular hours allowance: For varying shifts
  • Holiday allowance: 100% or 150% on public holidays
  • Overtime compensation: 125% or 150% after 40 hours

Monthly vs. annual calculation

Some costs don't hit every month, but you pay them annually. Spread these over 12 months for an accurate monthly picture:

💡 Converting annual costs:

  • Holiday pay: 8% of annual salary ÷ 12 months
  • 13th month: 1 monthly salary ÷ 12 months
  • Work clothing: €300 per year ÷ 12 = €25/month
  • Training costs: €600 per year ÷ 12 = €50/month

Personnel costs as percentage of revenue

From tracking this across dozens of restaurants, personnel costs typically run between 28% and 38% of revenue in hospitality. If you know what an employee costs monthly, you can calculate how much revenue you need to cover their wages.

⚠️ Note:

Don't forget costs for sick leave replacement, temporary staff and training new employees. This adds another 5-10%.

Digital tracking of personnel costs

Many restaurants track personnel costs in Excel, but that gets messy fast. A system like KitchenNmbrs helps you monitor all costs per employee and see your total monthly personnel expenses. This way you can better control your personnel budget and forecast what new hires will cost.

How do you calculate total personnel costs? (step by step)

1

Gather all salary information

Note the gross salary per employee per month. Also add allowances such as shift allowance, irregular hours allowance and any 13th month. This is your basis for all further calculations.

2

Calculate social contributions

Add up the employer premiums: unemployment insurance (2.9%), disability insurance (0.7%) and health insurance (6.9%). This comes to approximately 10.5% of gross salary. Multiply the gross salary by 1.105 to get the amount including social contributions.

3

Add holiday pay and pension premium

Calculate 8% holiday pay over the annual salary and divide by 12 for the monthly amount. Add the employer pension premium (usually 5-7% of gross salary). Also add travel allowance and other fixed allowances.

4

Add all costs together

Gross salary + social contributions + holiday pay + pension premium + allowances = total personnel costs per month. This amount is often 25-40% higher than the gross salary alone.

✨ Pro tip

Track your personnel cost trends over 6-month periods to spot seasonal patterns and budget more accurately. Most restaurants see 15-20% higher personnel costs during peak seasons due to overtime and temporary staff.
