Labor cost ratio reveals exactly how much of your revenue disappears into payroll each month. Most restaurant owners get this calculation wrong and wonder why their profit margins look terrible. The math is straightforward once you know which costs to include.
What is labor cost ratio?
Labor cost ratio measures what portion of your revenue feeds your payroll. It covers every dollar you spend on staff: wages, social contributions, holiday pay, sick leave coverage and employer taxes.
💡 Example:
Restaurant with €50,000 revenue per month:
- Gross wages: €12,000
- Social contributions: €3,600
- Holiday pay/13th month: €1,400
Total personnel costs: €17,000 = 34% labor cost ratio
The formula for labor cost ratio
Labor cost ratio = (Total personnel costs / Revenue) × 100
Always use revenue excluding VAT for accurate results. Industry benchmarks work this way, so your numbers will actually mean something.
What counts as personnel costs?
Every penny you spend on your team:
- Gross wages - actual pay to employees
- Social contributions - employer portion (typically 30% of gross)
- Holiday pay - 8% of annual salary
- 13th month or bonus - if you offer these
- Sick leave replacement - temporary staff during illness
- Work clothes and training - if substantial amounts
⚠️ Attention:
Too many operators only count gross wages. This makes your labor cost appear much lower than reality. Always include the complete employer burden.
Benchmarks by restaurant type
Typical labor cost ratios across different concepts:
- Fine dining: 35-45% (intensive service requirements, skilled staff)
- Casual dining: 28-38% (moderate service needs)
- Fast casual: 25-32% (streamlined operations)
- Delivery/takeaway: 20-28% (minimal front-of-house)
- Bar/café: 25-35% (varies with food complexity)
💡 Example calculation:
Bistro with 4 FTE (full-time equivalents):
- Monthly revenue: €35,000 excl. VAT
- Gross wages: €8,800
- Social contributions (30%): €2,640
- Holiday pay/reserves: €1,060
Labor cost ratio: (€12,500 / €35,000) × 100 = 35.7%
For a bistro this runs high. Target should be 32% or lower.
What if your labor cost is too high?
Above 40% makes turning a profit nearly impossible. Here's how to fix it:
- Schedule smarter - align staffing with actual busy periods
- Boost productivity - improve prep efficiency, faster ticket times
- Drive revenue per hour - quicker table turns, strategic upselling
- Cross-train your team - chef who can expo during quieter shifts
⚠️ Attention:
Cutting staff can backfire badly. Too few people creates awful service, which destroys revenue. You need to balance costs with quality.
Labor cost in combination with other ratios
Don't examine personnel costs in isolation. Combined with food cost, you get your complete operational picture - a pattern we see repeatedly in restaurant financials where operators fixate on one number while the real story emerges from the combination:
- Prime cost = Food cost + Labor cost
- Healthy prime cost: 55-65% of revenue
- If prime cost hits 65%+: almost nothing left for rent, utilities and profit
💡 Example prime cost:
Restaurant with €40,000 monthly revenue:
- Food cost: 32% = €12,800
- Labor cost: 30% = €12,000
- Prime cost: 62% = €24,800
Remaining for rent, utilities, profit: €15,200 (38%)
How often to check?
Monthly reviews work well for labor cost ratio. Weekly checks create too much noise (schedules naturally fluctuate), but quarterly reviews mean you're always behind the curve.
Smart operators track food costs with dedicated software, then combine these numbers with labor calculations for complete prime cost visibility.
How to calculate labor cost ratio? (step by step)
Gather all personnel costs from last month
Add up: gross wages, social contributions (approximately 30% of gross), holiday pay reserves, paid bonuses, and temporary staff costs. Don't forget employer contributions - those are often 25-35% on top of the gross wage.
Calculate your monthly revenue excluding VAT
Get your revenue from your POS system or accounting. Convert to excluding VAT: revenue divided by 1.09 (at 9% VAT). This gives a more accurate picture than revenue including VAT.
Apply the formula and compare with benchmark
Divide total personnel costs by revenue excl. VAT and multiply by 100. Compare with the benchmark for your type of business: casual dining 28-38%, fine dining 35-45%, fast casual 25-32%.
✨ Pro tip
Calculate your labor cost ratio every 2 weeks during your restaurant's first 6 months of operation. This frequent monitoring reveals scheduling patterns and productivity issues before they devastate your margins.

Frequently asked questions
Should I include social contributions in labor cost?
Absolutely. Social contributions are real money leaving your account for staff. Calculating only gross wages gives you a dangerously optimistic view of what your team actually costs.
What is a healthy labor cost ratio for a restaurant?
Casual dining should hit 28-38%, depending on service level. Fine dining can run higher at 35-45%, fast casual should stay 25-32%. Anything above 40% makes profit nearly impossible.
How often should I check my labor cost?
Monthly tracking works effectively. Weekly reviews create unnecessary panic since schedules naturally vary, while quarterly checks mean you're always reacting too late to problems.
Do I count myself as owner in labor cost?
Depends on how you pay yourself. If you draw a real salary, include it. If you work for free, calculate as if paying yourself €3,000-4,000 monthly for honest analysis.
What if my labor cost comes out above 40%?
You're in serious trouble profit-wise. Focus on smarter scheduling, better productivity per person, or growing revenue. Sometimes the problem isn't too many staff but too little sales per operating hour.
Should I calculate labor cost differently during seasonal fluctuations?
Track both monthly actuals and rolling 3-month averages during seasonal swings. This smooths out natural ups and downs while keeping you aware of real trends. Plan staffing changes 2-3 weeks ahead of expected seasonal shifts.
