Labour is usually the largest single line on the rota — and the easiest one to lose control of. If you've ever closed a quiet shift only to find your wage bill ate the day's takings, you've felt the cost of running blind on labour percentages.

Explore Annaizu’s shift planning and availability for a more efficient and compliant way to manage this area.

For employers looking to streamline operations, Annaizu’s shift planning and availability can support a more efficient and compliant workflow.

This guide explains what labour cost percentage actually measures, what a healthy figure looks like in UK hospitality, retail and care, and the steps managers

can take this week to bring the number under control.

What Is Labour Cost Percentage?

Labour cost percentage is the share of your revenue that goes towards paying the people delivering it. The formula is simple:

Labour Cost % = (Total Labour Cost ÷ Total Revenue) × 100

"Total labour cost" should include gross wages, employer NI, pension contributions, holiday accrual and any overtime premiums — not just the take-home figure on the payslip. "Total revenue" is your net sales for the same period (excluding VAT).

Worked Example

A café takes £8,400 in a week and spends £2,940 on staff wages, NI and pension once everything is added in. The labour cost percentage is (2,940 ÷ 8,400) × 100 = 35%.

What's a Healthy Labour Cost Percentage in the UK?

The right benchmark depends on the sector and the business model. As a rough guide for UK operators in 2026:

• Quick-service food and coffee: 25–30%
• Casual dining and pubs: 28–34%
• Full-service restaurants and hotels: 30–35%
• Independent retail: 15–20%
• Care and domiciliary services: 55–65%

If you're consistently outside the upper end of these ranges, the rota is almost certainly the lever to pull.

How to Calculate It Each Week

1. Pull the Right Numbers

Use the same period for cost and revenue — a Monday-to-Sunday trading week is the simplest. Take the wage figure from your payroll or rota software, add employer NI and pension on top, and pull net revenue from your till or POS.

2. Track It on a Rolling Basis

One week tells you very little; four weeks tells you a trend. Plot it on a simple chart so you can see whether labour creeps up after a bank holiday, a menu change or a promotion. Annaizu's reports and insights module does this automatically by week, site and department.

3. Compare to Forecast, Not Just Last Year

Last year's number is a sanity check; the forecast tells you whether this week's plan is realistic. If you're rota'ing 35% but forecasting 28%, you have a planning problem before the week has even started.

5 Ways to Reduce Labour Cost Percentage

Build the Rota Against a Demand Forecast

Most overspend happens in the first hour and last hour of trading, where staff are scheduled by habit rather than need. A demand-led rota — built from sales data, footfall and bookings — typically removes 2–4% from the labour line. Annaizu's labour cost control and forecasting tools surface the spend live as you draft.

Stagger Start and Finish Times

Replace blanket 9-to-5 shifts with 30- and 60-minute staggers around your peaks. The cover stays the same; the wage cost drops.

Cap Overtime at Source

Overtime is rarely a planning decision — it's usually a missed clock-out. Use time and attendance clock-in to enforce shift end times and flag breaches before they hit payroll.

Tighten Holiday and Absence Cover

Last-minute cover is almost always the most expensive shift of the week. Plan annual leave further ahead and use holiday and absence management to spread it across quieter weeks.

Train Multi-Skilled Staff

One person who can run the till, the floor and the kitchen pass is worth two single-skilled team members on a quiet shift. Track skill tags inside people management and HR tools so the right person is always available.

Conclusion

‍

Labour cost percentage is the single most useful number a rota-running manager can track. Calculate it weekly, plot it against a forecast, and treat anything above your sector benchmark as a planning issue rather than a payroll one.

Annaizu's rota and workforce management software gives UK operators a live labour percentage as they build the rota — so the number is right before the shift starts, not three weeks after it ends.
