Payroll as a % of Revenue: What's Healthy for Your Sector (And What's Silently Killing You)

The Labour Cost That Grows Without Permission#

A restaurant with £18,000 weekly revenue and £6,200 weekly payroll has a 34.4% labour cost — within benchmark for full-service dining. Three months later, revenue is flat at £18,000 but payroll has crept to £7,100 — 39.4%. Nobody made a decision to increase labour costs. What happened: two extra staff were hired for the summer, the summer rush was modest, two hours of overtime per shift per week accumulated across eight staff, and a senior chef got a pay rise that wasn't modelled against revenue impact. Five small decisions, no single one unreasonable, produced a 5-point labour cost inflation that costs £900/week — £46,800/year.

Sector Benchmarks You Can Actually Use#

Retail (product-focused, lower service intensity): 12–18% labour cost as % of revenue. Restaurant (casual dining): 28–35%. Restaurant (fine dining): 32–40%. Salon and personal services: 35–50% (commission-based structures sit at the high end). Repair and field service: 20–30%. Logistics and delivery: 18–28%. Manufacturing/factory: 15–25%. If your labour % is more than 5 points above your sector benchmark, investigate before assuming the benchmark is wrong. The benchmark represents businesses that are profitable in your sector — yours should be too.

Breaking Down Labour Cost by Day and Shift#

A high overall labour % often hides variation that makes it manageable. Tuesdays and Wednesdays might have labour costs of 45–50% because staffing levels are set for the weekend and revenue is half what it is Saturday. Your Saturday labour cost might be 22% — excellent. The average 35% masks a structural overstaffing problem on weekdays. AskBiz breaks labour cost by day, shift, and location using your POS revenue data and AskBiz clock-in records. The Wednesday problem becomes visible. You adjust the Tuesday/Wednesday rota. Average drops to 29%.

Flexible Labour vs Fixed Headcount#

Businesses with high labour cost % often have too much fixed (salaried or guaranteed-hours) labour relative to their revenue variability. If your revenue swings 40% between your best and worst weeks, your labour cost should swing too — but salaried staff means it doesn't. Building a labour model with a fixed core (essential roles, minimum hours) and a flexible periphery (on-call staff, zero-hours for peaks, agency cover) allows labour cost to track revenue more closely. The goal is a labour % that stays within 3–4 points of target regardless of revenue level.

Connecting Rota to Revenue Forecast#

The best labour cost management happens before the shift is worked, not when the payroll bill arrives. AskBiz connects your revenue forecast (this Saturday is expected to be £4,200 based on reservations plus historical data) to your rota. It shows the projected labour cost for the scheduled hours against the expected revenue — giving you a preview of Saturday's labour % before the day happens. If the rota has 14 staff scheduled for a £4,200 day, and that produces a 42% labour cost forecast, you make the rota change on Thursday, not after seeing the Saturday P&L in week two of next month.

• Payroll is the largest cost for most service and hospitality businesses — and the hardest to manage because it feels personal.
• Tracking payroll as a percentage of revenue gives you an objective number to manage against.
• Restaurants target 25–35%.
