Most chefs think 30 extra minutes of mise-en-place daily is no big deal, but that's a costly myth. Those seemingly harmless half-hours compound into thousands of euros annually. Many kitchens completely underestimate how extra prep time destroys their labor budgets.
What is the real cost of extra mise-en-place?
Mise-en-place time equals pure labor expense. Every extra minute your team spends on prep burns money without generating a single euro in revenue.
💡 Example calculation:
Restaurant with 2 chefs doing 30 minutes extra mise-en-place:
- Average chef hourly wage: €18.00 (incl. employer contributions)
- Extra time: 30 minutes = 0.5 hours
- 2 chefs × 0.5 hours × €18.00 = €18.00 per day
- 6 days per week × 52 weeks = €5,616 per year
Total annual costs: €5,616
Calculate your own situation
The formula for extra mise-en-place costs is straightforward, but the financial impact hits hard:
Annual costs = Number of chefs × Extra hours × Hourly wage × Working days per year
⚠️ Note:
Always calculate with the full hourly wage including employer contributions (social premiums, holiday pay, etc.). This runs 25-30% higher than gross wage.
Where does extra mise-en-place time come from?
Most extra prep time stems from:
- Poor planning: Starting prep too late
- Unclear recipes: Chefs don't know exactly how much to make
- No standard portions: Every chef does it differently
- Wrong sequence: Inefficient workflow
💡 Example of inefficiency:
Chef makes 2 liters of tomato sauce daily, but uses an average of 1.5 liters:
- Extra prep time: 10 minutes per day
- Ingredient waste: 0.5 liters × €3.50/liter = €1.75
- Total extra costs per day: €4.75 (time + waste)
Per year: €1,462 in unnecessary costs
Optimization strategies
With this approach, you'll trim both time and money from mise-en-place:
- Standardize recipes: Document how much of each item you need daily
- Plan based on reservations: Make only what you need
- Batch cooking: Make larger quantities less frequently
- Prep schedules: Who does what and when
💡 Practical savings example:
Restaurant that optimizes mise-en-place from 3 hours to 2.5 hours per day:
- Savings: 0.5 hours per day
- 2 chefs × 0.5 hours × €18.00 = €18.00 per day
- Annual savings: €5,616

Digital support for mise-en-place
From analyzing actual purchasing data across different restaurant types, systems that document recipes and portions dramatically reduce prep time waste. You can calculate exactly how much you need based on expected revenue.
This prevents both waste and shortages, and ensures your team can work more efficiently without extra stress.
How do you calculate the impact of extra mise-en-place time?
Measure your current mise-en-place time
Track for a week how much time each team member spends on prep. Include all activities: cutting, marinating, making sauces, preparing garnishes.
Calculate the hourly costs per employee
Add 25-30% to the gross wage for employer contributions (social premiums, holiday pay, etc.). A chef earning €15 gross costs you approximately €18-20 per hour.
Multiply by your working days
Use the formula: Number of people × Extra hours × Hourly costs × Working days per year. Include all chefs involved in mise-en-place.
✨ Pro tip
Calculate your exact hourly cost by dividing total annual labor expenses by actual hours worked—this typically runs €22-28 per hour including all benefits. Multiply that by your daily excess prep time for the real annual impact.

Frequently asked questions
Should I include employer contributions in the calculation?
Yes, always. Employer contributions (social premiums, holiday pay, etc.) add 25-30% on top of gross wage. Without these costs, you'll get an unrealistic picture of your actual expenses.
How do I know if my mise-en-place time is normal?
Standard is 1.5-2.5 hours mise-en-place per chef per day, depending on your menu type. More than 3 hours often signals inefficiency or overly complex dishes.
Can I reduce mise-en-place time without losing quality?
Absolutely, through standardization and better planning. Documenting exact quantities, batch cooking, and prep schedules can save 20-30% of time without quality loss.
What if I don't have fixed working days?
Then calculate based on average working days per month × 12. For seasonal businesses, you can only include the active months in your calculation.
How do I relate mise-en-place costs to my revenue?
Mise-en-place time shouldn't exceed 8-12% of your total labor costs. With an average labor cost of 30% of revenue, 2-4% of your revenue for mise-en-place is normal.
Should I factor in prep items that carry over to the next day?
Yes, track your actual usage versus production for items with 2-3 day shelf life. Many kitchens overestimate carryover value and still waste 15-20% of batch-prepped items through spoilage.
