Most restaurants lose €200-400 monthly by not tracking labor costs per dish. You might know your monthly staff expenses, but without understanding how much labor goes into each plate, you can't determine true profitability. This calculation reveals which dishes actually make money.
Why labor costs per dish matter
You can craft excellent pasta with €4 in ingredients, but if your chef needs 45 minutes while competitors finish the same dish in 15, you're earning far less. Labor typically represents 25-35% of revenue, so minor differences create major profit swings.
💡 Example:
Restaurant A and B both sell risotto for €18.50:
- Restaurant A: 15 minutes prep time
- Restaurant B: 30 minutes prep time
- Kitchen hourly wage: €18 (incl. employer costs)
Restaurant A: €4.50 labor costs per risotto
Restaurant B: €9.00 labor costs per risotto
Difference: €4.50 per dish!
The basic formula for labor costs per dish
The math appears straightforward, but several pitfalls await:
Labor costs per dish = (Kitchen hourly wage × Prep time in hours)
Labor costs % = (Labor costs per dish / Selling price excl. VAT) × 100
⚠️ Note:
Always use total hourly wages including employer costs (pension, sick leave, holiday pay). This runs 30-40% above gross salary.
Step 1: Calculate your actual kitchen hourly wage
Grab last month's total kitchen payroll and divide by hours worked:
- Gross kitchen wages
- Employer costs (pension, unemployment insurance, sick leave)
- Holiday pay
- Possibly 13th month bonus
💡 Example hourly wage calculation:
Kitchen team of 3 people, monthly costs:
- Gross wages: €8,500
- Employer costs: €2,550 (30%)
- Total: €11,050 per month
- Hours worked: 520 hours
Hourly wage: €11,050 / 520 = €21.25 per hour
Step 2: Measure prep times realistically
Here's where many calculations fail. Don't measure just 'hands-on' time — track the complete time investment per dish:
- Preparing mise-en-place
- Actual cooking/preparation
- Garnishing and plating
- Cleaning between orders
A dish with '10 minutes cooking time' often requires 15-20 minutes of total labor. I've seen restaurants underestimate prep times by 40%, a mistake that costs the average restaurant EUR 200-400 per month in miscalculated dish profitability.
Step 3: Calculate labor costs percentage
Like food cost calculations, measure labor costs against your selling price excluding VAT:
💡 Complete calculation:
Steak with fries, selling price €28.50 incl. VAT:
- Selling price excl. VAT: €28.50 / 1.09 = €26.15
- Prep time: 18 minutes = 0.3 hours
- Kitchen hourly wage: €21.25
- Labor costs: €21.25 × 0.3 = €6.38
Labor costs %: (€6.38 / €26.15) × 100 = 24.4%
Benchmarks: what's normal?
Labor costs fluctuate dramatically based on kitchen style and dish complexity:
- Fast food/snacks: 15-25% labor costs
- Casual dining: 20-30% labor costs
- Fine dining: 25-40% labor costs
- Complex dishes: up to 45% labor costs
⚠️ Note:
Food cost + labor costs combined shouldn't exceed 65%, otherwise insufficient margin remains for overhead and profit.
What do you do with this information?
Armed with per-dish labor costs, you can make smarter decisions:
- Menu optimization: Push dishes with lower labor costs
- Price adjustments: Increase prices on labor-intensive items
- Recipe modifications: Streamline preparation methods
- Mise-en-place strategy: Prep more components ahead to reduce order time
Tools like a food cost calculator can record prep times per recipe and automatically calculate labor costs per dish, eliminating manual calculations.
How do you calculate labor costs per dish? (step by step)
Calculate your actual kitchen hourly wage
Add up all payroll costs from last month (gross + employer costs + holiday pay) and divide by the total hours worked. This gives you the real hourly wage including all costs.
Measure the total prep time per dish
Time from the moment someone starts with this dish until it's ready on the plate. Also include mise-en-place and cleaning, not just cooking time.
Calculate labor costs and percentage
Multiply hourly wage by prep time in hours for labor costs per dish. Divide this by your selling price excl. VAT and multiply by 100 for the percentage.

Frequently asked questions
Should I include dishwasher wages in my labor cost calculations?
Absolutely — factor in all kitchen staff who touch the dish. Calculate an average hourly rate for your entire kitchen team, including dishwashing and prep staff.
My signature pasta has 35% labor costs — is this acceptable?
That depends on your food cost percentage. If combined food and labor costs exceed 65%, you're likely underpricing that dish. Consider raising the price or simplifying preparation steps.
How frequently should I re-measure prep times for accuracy?
Review prep times quarterly, especially after recipe changes or new staff onboarding. Experienced cooks typically work 20-30% faster than newcomers, affecting your calculations.
Can I reduce labor costs without compromising food quality?
Yes, through strategic mise-en-place, improved workflow planning, and streamlined preparation techniques. Small recipe tweaks often save significant time without affecting taste.
What if my labor costs exceed industry benchmarks significantly?
First examine your preparation workflow — can processes be more efficient? Then evaluate pricing — perhaps labor-intensive dishes deserve premium pricing. Some restaurant concepts naturally carry higher labor costs.
Should I calculate labor costs differently for dishes requiring specialized skills?
Use your actual wage rates for specialized positions. If your pastry chef earns €25/hour while line cooks earn €18/hour, calculate dessert labor costs using the higher rate for accuracy.
