Your Restaurant Labour Cost Is Over 35% and You Don't Know It Yet

The Labour Cost Drift Problem#

Marco runs a 60-cover Italian restaurant in Manchester. His weekly revenue averages £18,000. His target labour cost is 30% = £5,400/week. But this week he scheduled 8 front-of-house staff across 5 shifts plus 4 kitchen staff. Total scheduled hours: 220. Average hourly cost (wage + NI + pension): £13.50. Total labour cost: £2,970. Wait — that looks fine. Except Tuesday's dinner service was cancelled due to a private event booking mix-up. The restaurant did £1,200 Tuesday instead of £3,800. Revenue dropped £2,600. But all Tuesday staff were already scheduled and paid. Labour cost for that day: £720 labour against £1,200 revenue = 60% labour cost. For the week: £18,000 - £2,600 = £15,400 actual revenue. Labour cost unchanged at £2,970. Labour %: 19.3% of planned revenue becomes 19.3% calculated on planned revenue — but the real ratio is £2,970 / £15,400 = 19.3%... Except Marco didn't adjust for the higher-paid weekend staff. Real weekly labour: £6,200. Labour %: 40.3%. He discovers this at month-end. Four weeks too late.

Why Weekly Labour Review Matters#

Restaurant finances are weekly in nature. Staff are scheduled weekly. Revenue peaks are weekly (Friday/Saturday). COGS deliveries are weekly. If you only review labour cost monthly, you are seeing a blended average of 4 weeks — including good weeks (bank holiday weekend: 22% labour cost) and bad weeks (quiet January Monday: 48% labour cost). The monthly average looks like 32%. You think everything's fine. But you had two weeks at 40%+ labour cost that should have triggered rota changes the following week. You didn't know. You didn't change the rota. You lost £3,000-5,000 in unnecessary labour overspend.

AskBiz Weekly Labour Cost Dashboard#

AskBiz connects your POS (daily revenue) with your payroll data (weekly wages). Each Monday morning it shows: (1) Last week's revenue: £16,200. (2) Last week's total labour cost: £5,800. (3) Labour cost %: 35.8% (over target of 30%). (4) Day-by-day breakdown: which days were high/low labour %. (5) Department breakdown: kitchen 38%, FOH 33%, management 28%. (6) Comparison: this week vs. last 4 weeks vs. same week last year. From this, Marco can see: Tuesday dinner cancelled → Tuesday labour was 58%. Next week, if Tuesday looks quiet again, he can reduce the Tuesday rota by 2 staff and save £260.

Scheduling to Revenue Forecast#

The proactive use of AskBiz is scheduling future rotas based on revenue forecasts. AskBiz shows projected revenue by day of week (based on historical patterns and bookings). If next Thursday is a bank holiday and usually does 40% less revenue than a normal Thursday, Marco can reduce Thursday staffing. Without this forecast, Marco schedules 6 FOH staff on Thursday (£780 in wages) for a day that does £1,800 revenue — a 43% labour ratio. With the forecast, he schedules 4 FOH staff (£520 in wages) for the same £1,800 — a 29% ratio. That's £260 saved on one day. Across a year, systematic scheduling to forecast saves £8,000-15,000 in a typical 60-cover restaurant.

Real Example: Singapore Restaurant Group#

A 3-outlet casual dining group in Singapore was running 34% labour cost against a target of 29%. Owner reviewed monthly P&L but couldn't pinpoint the problem. After connecting AskBiz to their POS and HR system: Weekly reports showed Saturday lunches were the biggest culprit — full staffing deployed despite Saturday lunch being 35% quieter than Saturday dinner. Adjusted Saturday lunch rota (reduced 3 staff). Annual saving: SGD $28,000 in labour overspend. Also identified: two outlets were paying kitchen overtime weekly because the prep shift was understaffed (creating overtime for dinner service). Adjusted prep shift timing. Additional saving: SGD $14,000/year. Total labour cost dropped from 34% to 30.5% — very close to target, with no reduction in service quality.

Beyond Labour: Full Cost Visibility#

AskBiz doesn't just track labour cost %. It combines labour with COGS (food cost) and overhead to give total weekly profitability. A restaurant with 30% labour + 32% food cost + 18% overhead = 20% net margin on £18,000 revenue = £3,600 weekly profit. Reduce labour to 28% = £3,960 weekly profit = +£360/week = +£18,720 per year. That extra £18,720 is the value of one weekly labour cost review. Ninety minutes per week. Significant compounding return.

• A healthy restaurant targets labour cost at 28-32% of revenue.
• When it drifts to 36-40%, the business is losing £3,000-8,000 per month in overspend.
• Most owners discover this at month-end when the accountant sends the P&L.
