Labor costs per shift remain the backbone of profitable restaurant operations across every type of establishment. Most operators still rely on instinct rather than data, creating overstaffed shifts that drain profits. Tracking these costs per service gives you the precision to staff each shift optimally.
What are labor costs per shift?
Labor costs per shift represent total personnel expenses for one service period, calculated as a percentage of that shift's revenue. This metric determines optimal staffing levels for different sales volumes.
💡 Example:
Saturday evening shift (18:00-24:00):
- Revenue: €3.200
- Chef: 6 hours × €18 = €108
- 2 servers: 12 hours × €12 = €144
- 1 dishwasher: 6 hours × €11 = €66
Total labor costs: €318 = 9.9% of revenue
Labor costs per shift formula
The calculation stays straightforward but demands consistent application:
Labor costs % = (Total personnel costs shift / Shift revenue) × 100
Always include gross hourly wages plus employer contributions. In hospitality, add roughly 25% on top of base wages.
⚠️ Watch out:
Don't skip employer contributions. A chef earning €15/hour actually costs €18.75/hour including pension premiums, insurance, and holiday pay.
Weekly planning with labor costs as your key metric
Historical data reveals patterns that transform your scheduling accuracy. Each weekday carries its own financial profile - a pattern we see repeatedly in restaurant financials across different markets and cuisines.
- Monday: Typically slow, maintain labor costs under 35%
- Tuesday-Thursday: Moderate volume, target 25-30%
- Friday-Saturday: Peak periods, achieve 20-25%
- Sunday: Unpredictable, build flexibility into plans
💡 Example weekly planning:
Restaurant with average €8.000 weekly revenue:
- Monday: €800 revenue → max €280 labor costs (35%)
- Friday: €1.800 revenue → max €450 labor costs (25%)
- Saturday: €2.200 revenue → max €550 labor costs (25%)
Schedule shifts within these financial boundaries.
Daily monitoring during the shift
Track performance throughout service to catch deviations early. If sales lag behind projections, cut staff immediately to protect margins.
- Review after 2 hours: does revenue match forecasts?
- At 20% revenue shortfall: consider releasing one team member
- At 30% revenue shortfall: definitely send someone home
⚠️ Watch out:
Maintain minimum staffing per function. You'll always need at least 1 chef, 1 server, and (during busy periods) 1 dishwasher, regardless of sales.
Seasons and special days
Seasonal variations and holidays demand adjusted target percentages. Christmas, Valentine's Day, and similar events operate under different labor ratios.
💡 Example adjustments:
- Christmas Eve: 15-20% (exceptional revenue, standard staffing)
- January: 30-35% (post-holiday slowdown)
- Summer vacation: 25-30% (location dependent)
Tools and registration
Document what succeeds and what fails for continuous improvement. Record for each shift: projected versus actual revenue, planned versus actual labor costs, and lessons for future scheduling.
Systems can help track this information and identify trends, enabling more accurate forecasting for your planning decisions.
How do you calculate labor costs per shift? (step by step)
Gather all personnel costs for the shift
Add up all hours of everyone who worked during the shift. Multiply by their hourly wage including 25% employer contributions. Don't forget anyone: chef, servers, dishwasher, bartender.
Note the exact revenue for that shift
Get the revenue from exactly that shift from your POS system. Not the whole day, but only the hours the staff worked. This gives you the correct ratio.
Calculate the percentage
Divide total personnel costs by shift revenue and multiply by 100. This percentage is your key metric for comparable shifts in the future.
✨ Pro tip
Track your Monday labor costs for 8 consecutive weeks - if they consistently exceed 32%, permanently reduce Monday staffing by one person. This single adjustment typically improves weekly profitability by 3-5%.

Frequently asked questions
What percentage should labor costs per shift target?
Restaurants typically aim for 20-35%, varying by establishment type and volume. High-volume shifts can achieve 20-25%, while slower periods may reach 35%. Anything above 40% seriously threatens profitability.
Should employer contributions be included in calculations?
Absolutely. Employees cost significantly more than their gross wages suggest. Add approximately 25% for employer contributions, holiday pay, and pension premiums. Without this, your calculations will underestimate true costs.
How do I predict revenue for scheduling purposes?
Analyze data from corresponding days in previous weeks and months. Identify emerging patterns: has business grown or declined consistently? Factor in weather conditions, holidays, and local events that might affect traffic.
What if labor costs exceed target percentages?
Determine whether the issue stems from overstaffing or underperforming sales. For chronic overstaffing: reduce scheduled hours. For unexpected low revenue: release staff mid-shift when possible.
Can staff always be sent home during slow periods?
Not in every situation. Minimum staffing levels must be maintained for basic operations. Typically require at least 1 chef and 1 server, plus 1 dishwasher for larger establishments.
How do split shifts affect labor cost calculations?
Calculate split shifts as separate service periods when there's a clear break in operations. This provides more accurate labor percentages for lunch versus dinner services, especially important for establishments with distinct meal periods.
What's the impact of overtime on shift labor costs?
Overtime significantly inflates labor percentages since you're paying 150% of regular rates. Monitor weekly hours closely and adjust scheduling to avoid overtime whenever possible, as it can push profitable shifts into loss territory.
