Chaotic prep work bleeds money from your kitchen every single day. Most restaurants still wing their mise-en-place, creating endless searching, duplicate tasks, and service stress. Here's exactly how to calculate what structured prep saves you.
What is efficiency gain from mise-en-place?
Efficiency gain measures how much time and money you save by having a fixed mise-en-place routine. The gap between improvising and working with structure typically costs you 30-60 minutes per service.
? Example:
Restaurant with 2 chefs, 6 days per week:
- Without structure: 45 min extra searching/prep per chef
- Wage costs: €18/hour per chef
- Extra time per day: 2 × 45 min = 1.5 hours
- Cost per day: 1.5 × €18 = €27
Annual waste: €27 × 6 × 52 = €8,424
Calculate your current time loss
First, measure how much time you're currently losing to inefficiency. The biggest time wasters are:
- Searching for ingredients: 5-15 minutes per chef per service
- Duplicate prep work: different chefs doing the same thing
- Incomplete prep: still restocking halfway through service
- Wrong portions: too much or too little prepared
⚠️ Note:
Measure this honestly for a week. Many business owners underestimate time loss. Ask your chefs to track how much time they spend on 'searching and restocking'.
The formula for efficiency gains
Use this formula to calculate your daily savings:
Daily savings = (Time saved per chef × Number of chefs × Hourly wage) + Material savings
? Example calculation:
Bistro with 3 chefs, hourly wage €17:
- Time saved per chef: 40 minutes = 0.67 hours
- Wage savings: 3 × 0.67 × €17 = €34.17
- Less waste from better portioning: €8.00
- Fewer stress errors (wrong dish): €5.00
Total daily gain: €47.17
Material savings through structure
A fixed mise-en-place routine also prevents material waste:
- Better portioning: less leftover, less restocking
- Less spoilage: you know exactly what you have
- No duplicate ordering: inventory overview
- Fewer stress errors: making wrong dishes
Typical material savings: €5-15 per day for an average restaurant. But that's the kind of thing you only learn after closing your first month at a loss.
ROI of mise-en-place system
The investment in a structured system pays for itself quickly:
? ROI example:
Investment in system (training, checklists, apps): €500
- Daily savings: €47
- Working days per month: 26
- Monthly profit: €47 × 26 = €1,222
Payback period: €500 / €1,222 = 12 days
Measurable improvement points
Track these KPIs to measure your efficiency gains:
- Prep time per chef: how many minutes for complete mise-en-place
- Service interruptions: how often do you need to restock
- Waste per day: what gets thrown away at the end of service
- Stress moments: when do you have to improvise
Measure this before and after implementing your new structure.
Structured prep planning tools
Tools like KitchenNmbrs help you structure your mise-en-place. You can link recipes to prep lists and calculate exactly how much you need based on expected covers. This prevents guesswork and waste.
How do you calculate efficiency gains? (step by step)
Measure current time loss per chef
Have each chef track for a week how much time they spend searching, restocking, and improvising. Add this up and divide by the number of working days to get an average per day.
Calculate wage costs of time loss
Multiply time loss per chef by their hourly wage and number of chefs. This gives you daily wage waste from inefficiency.
Add material waste
Estimate how much you lose daily from wrong portions, spoilage from poor inventory management, and stress errors. Add this to wage waste for total daily loss.
Calculate annual impact
Multiply daily loss by number of working days per year. This shows the total cost of lack of structure and the potential gain from improvement.
✨ Pro tip
Time your current mise-en-place for lunch prep over 5 consecutive days - you'll find prep time varies by 20-35 minutes daily without structure. Document these gaps to calculate your baseline waste.
