Managing labor costs is like balancing on a tightrope - lean too far either way and your restaurant falls. Most owners discover their personnel expenses are draining profits faster than they realized. Here's how to calculate your weekly labor cost percentage and regain control.
What is labor cost percentage?
Labor cost percentage reveals how much of every dollar earned gets eaten up by staff expenses. You're looking at the complete picture: wages, benefits, taxes, and all those hidden costs that add up.
💡 Example:
Bistro De Smulhoek had last week:
- Revenue: €8,500
- Personnel costs: €2,720
Labor cost percentage: (€2,720 / €8,500) × 100 = 32%
Which costs do you include?
Don't just count the obvious stuff. Every penny spent on staff matters:
- Gross wages: Base pay plus tips, overtime, and shift differentials
- Social contributions: Your share of insurance premiums and retirement funds
- Employer taxes: Unemployment, disability, and workers' comp
- Holiday pay: Vacation time that's accruing
- Sick leave: Money paid when staff can't work
⚠️ Important:
Employer taxes aren't optional extras - they're 15-25% on top of gross wages. Skip these and your numbers will be dangerously wrong.
The formula
Math doesn't lie, and this formula won't either:
Labor cost percentage = (Total personnel costs / Revenue excl. VAT) × 100
Strip out that VAT first. It's the government's money, not yours.
💡 Example calculation:
Restaurant last week:
- Revenue incl. VAT: €12,540
- Revenue excl. VAT: €12,540 / 1.09 = €11,505
- Personnel costs: €3,680
Labor cost percentage: (€3,680 / €11,505) × 100 = 32%
Benchmarks by business type
Here's what successful operators typically see:
- Fine dining: 35-45% (intensive service demands)
- Casual dining: 28-35%
- Fast casual: 25-32%
- Café/bistro: 25-35%
- Delivery only: 15-25% (minimal front-of-house needs)
⚠️ Important:
These ranges aren't gospel. Your concept, location, and service style create your unique target zone.
Weekly check routine
From years of working in professional kitchens, I've learned that weekly tracking prevents monthly disasters. Set up this simple routine:
- Tally every staff expense from Monday through Sunday
- Calculate against your VAT-free revenue
- Compare trends across recent weeks
- Flag unusual spikes from overtime or sick coverage
💡 Practical example:
Pizzeria Mario's tracks every Monday morning:
- Week 1: 28% labor cost
- Week 2: 31% labor cost
- Week 3: 38% labor cost (head cook called in sick, hired temp)
Mario catches problems early instead of getting blindsided at month-end. Smart tools like KitchenNmbrs can automate this tracking.
How do you calculate your labor cost percentage? (step by step)
Gather all personnel costs for the week
Add up: gross wages, social contributions, employer taxes, holiday pay, and any sick leave. Check your payroll administration or ask your accountant for total personnel costs.
Calculate your revenue excluding VAT
Divide your revenue including VAT by 1.09 (at 9% VAT). For revenue of €10,900 this becomes €10,900 / 1.09 = €10,000 excluding VAT.
Calculate the percentage
Divide your total personnel costs by your revenue excl. VAT and multiply by 100. With €3,000 personnel costs and €10,000 revenue this becomes: (€3,000 / €10,000) × 100 = 30%.
✨ Pro tip
Run your labor percentage calculation separately for your 3 busiest shifts versus your 3 slowest shifts each week. You'll often find quiet periods running 8-12% higher due to minimum staffing requirements.

Frequently asked questions
Should I include VAT when calculating labor cost percentage?
Never include VAT in your revenue calculation. That money belongs to the tax authority, not your business. Always use your VAT-exclusive revenue for accurate percentages.
My labor cost percentage hit 42% - what's wrong?
You're either overstaffed for your sales volume or your revenue per labor hour is too low. Check your scheduling against actual customer flow and consider adjusting staff levels or improving sales per shift.
Do I count my own salary as the owner?
If you draw a regular paycheck, include it in labor costs. If you don't pay yourself formally, leave it out. Stay consistent with whichever method you choose for meaningful comparisons.
What if my percentage varies wildly week to week?
Seasonal businesses and new restaurants often see big swings. Track the pattern over 8-12 weeks to identify your baseline. Sudden spikes usually mean scheduling problems or unexpected coverage costs.
How do tips affect my labor cost calculation?
Include any tips you pay out through payroll since they're a labor expense. Tips kept directly by staff don't count toward your labor costs.
Should I calculate this differently for kitchen vs front-of-house staff?
Track them separately if you want detailed insights into each department's efficiency. Most operators find the combined percentage sufficient for weekly monitoring, then drill down monthly.
