Labour Cost as a Percentage of Revenue: What the Numbers Should Look Like

Labour is the largest controllable cost in most service businesses. Unlike rent or equipment leases, it flexes - you can schedule more or fewer hours depending on demand. That flexibility is an advantage, but only if you track whether your labour spend is in line with your revenue.

The Benchmark by Industry

Labour cost as a percentage of revenue varies significantly by sector. Here are realistic benchmarks:

These are ranges, not targets. A restaurant running 28% labour cost and high revenue is healthier than one running 28% on thin margins. The percentage matters only in context of profitability.

How to Calculate It

The formula is direct:

Labour cost % = (Total labour cost / Total revenue) x 100

Total labour cost includes:

• Gross wages
• Employer social contributions (varies by country, typically 20-35% on top of gross wage)
• Overtime premiums
• Paid leave and sick leave
• Agency and temp staff costs

Revenue is your gross revenue before any deductions. Do not net out VAT - you want to see what labour costs relative to actual money flowing through the business.

What Drives the Number Up

Labour percentage rises when revenue drops or labour cost grows. The scheduling-related causes:

• Overstaffing during low-traffic periods - Scheduling 8 staff for a Tuesday morning that consistently needs 5 burns hours without output
• Excessive overtime - Overtime at 125-150% premium inflates cost without proportional revenue gain
• Poor rota design - Gaps that require last-minute cover, often at agency rates, add cost outside the planned budget
• High turnover - Replacing an employee costs money. Onboarding new staff takes time when they are productive at 60-70% capacity for the first month
• Untracked hours - If staff clock in early or leave late and you do not monitor it, those minutes accumulate

What Drives the Number Down

Sustainable reduction comes from better matching of hours to demand, not from cutting staff to the bone:

• Analyse your revenue by hour and day. Match scheduled headcount to actual demand curves
• Reduce unplanned overtime by improving schedule reliability
• Cross-train staff so you can flex roles during mixed-demand periods instead of carrying excess headcount in one function
• Reduce agency dependency by maintaining a reliable pool of part-time and flexible staff

The Trap of Cutting Too Deep

Labour cost percentage can be manipulated lower in ways that damage the business:

• Understaffing peak periods sacrifices revenue and customer satisfaction
• Cutting full-time roles and replacing with casual labour increases training overhead and quality variation
• Ignoring turnover as a cost understates the true labour percentage

A restaurant that runs 22% labour cost because it is perpetually understaffed, has 80% annual staff turnover, and serves 15% fewer covers than capacity - that is not efficiency. It is managed decline.

The Scheduling Connection

Scheduling decisions are the fastest lever on labour cost percentage. Every week, the rota determines:

• Total hours scheduled (direct cost)
• Whether those hours match demand patterns (revenue per labour hour)
• How many hours fall into overtime bands (cost multiplier)
• Whether staff swaps or no-shows create emergency coverage costs

Managers who review their labour cost percentage weekly against scheduled hours - before the week starts, not after - make better decisions. They can cut a Tuesday shift before it runs, not regret it on Friday when the numbers land.
