A chef once told me his restaurant was bleeding money, but he couldn't figure out where. Turns out, his team was spending 6 hours daily on prep work that he'd never calculated. Most kitchens spend 15-30% of their time on mise-en-place without tracking what it actually costs them.
What are mise-en-place costs?
Mise-en-place costs consist of all the time and ingredients you invest in preparations before service begins. This includes:
- Cutting and washing vegetables
- Making sauces and dressings
- Preparing meat and fish
- Setting up garnishes and decorations
- Portioning base ingredients
These costs break down into labor costs (time from your kitchen team) and ingredient costs (what you use for preparations).
The calculation step by step
To calculate your mise-en-place costs as a percentage of revenue, you need three components:
? Formula:
Mise-en-place % = (Labor costs + Ingredient costs) / Daily revenue × 100
Calculating labor costs
Add up how many hours your team spends on preparations and multiply by the hourly wage including employer contributions.
? Example labor costs:
Daily mise-en-place: 4 hours
- Chef: 2 hours × €22/hour = €44
- Kitchen assistant: 2 hours × €16/hour = €32
Total labor costs: €76
⚠️ Note:
Calculate with hourly wage including employer contributions (approximately 30% on top of gross salary). A cook earning €18 gross costs you approximately €23.40 per hour.
Ingredient costs for mise-en-place
These are the costs of ingredients you use for preparations but don't directly sell to guests:
- Oil and butter for frying and roasting
- Herbs and spices
- Base ingredients for sauces
- Cutting waste from vegetables and meat
? Example ingredient costs:
Daily mise-en-place ingredients:
- Sauces and dressings: €18
- Oil, butter, herbs: €12
- Vegetable cutting waste: €8
- Garnishes and decoration: €6
Total ingredient costs: €44
Complete calculation with example
Now you can calculate the total percentage:
? Full example:
Restaurant with daily revenue of €2,500:
- Labor costs mise-en-place: €76
- Ingredient costs mise-en-place: €44
- Total mise-en-place costs: €120
Percentage: (€120 / €2,500) × 100 = 4.8%
Benchmarks and guidelines
Common mise-en-place costs as a percentage of revenue:
- Fine dining: 6-10% (lots of handwork, complex dishes)
- Casual dining: 3-6% (moderate complexity)
- Fast casual: 2-4% (simple prep)
- Pizzeria/grill: 2-3% (minimal preparations)
⚠️ Note:
Above 8% mise-en-place often becomes too expensive. It's the kind of thing you only learn after closing your first month at a loss - every minute of prep work needs to justify its cost.
How to lower your mise-en-place costs
If your percentage is too high, these are effective ways to save:
- More efficient planning: Only prep what you really need
- Batch cooking: Make larger quantities of sauces to spread labor costs
- Simpler garnishes: Easier decorations save time
- Better timing: Prep during quiet moments with cheaper staff
With a food cost calculator like KitchenNmbrs you can track which prep activities take the most time, so you can optimize more strategically.

How do you calculate mise-en-place costs? (step by step)
Measure your prep time over one week
Track how many hours your team spends daily on preparations. Note this for different team members and add them up. Do this for at least one week to get an average.
Calculate your labor costs per day
Multiply the prep hours per person by their hourly wage including employer contributions. Add all labor costs for mise-en-place together for one day.
Add up your ingredient costs for prep
Calculate what you spend daily on oil, herbs, sauces, and cutting waste for preparations. These are costs that don't go directly into a dish but are still necessary.
Divide by your daily revenue and multiply by 100
Use the formula: (Labor costs + Ingredient costs) / Daily revenue × 100. This gives you the percentage of your revenue that goes to mise-en-place.
✨ Pro tip
Track your prep times for exactly 14 days and calculate the percentage weekly. You'll discover that Mondays typically cost 40% more in prep time than other weekdays due to weekend inventory depletion.
