Indicative estimate. Gross wages assume the average rate and hours apply to every person for 52 weeks. Employer on-costs use the secondary Class 1 NI rate (15% above £5,000 a year) and the 3% auto-enrolment minimum pension on qualifying earnings (£6,240–£50,270), at 2026-27 thresholds. Real figures vary with reliefs (e.g. the Employment Allowance), pension scheme basis and individual pay. Not tax advice. WagePilot shows your true live labour cost as people clock in.

What your wage bill really costs

Your gross wage bill is the simple part: staff × average rate × hours. The number that actually leaves the business is higher, because employers also pay employer’s National Insurance (15% on pay above a £5,000 secondary threshold) and a minimum 3% auto-enrolment pension on qualifying earnings (£6,240–£50,270). Together those on-costs typically add 10–15% on top of a full-timer’s pay — worth knowing before you commit to a new hire or a busy rota.

For most shift businesses, labour is the largest controllable cost, and the difference between a good month and a bad one is often a handful of overstaffed quiet shifts and a little unplanned overtime. The problem is timing: by the time the wage bill lands with payroll, the overspend has already happened.

WagePilot turns the wage bill into something you watch in real time. As staff clock in, the live labour-cost board shows what the floor is costing right now and as a share of the day, so you can send someone home early or pull in cover before the cost runs away.

Labour cost questions

How do I calculate my weekly wage bill?

Multiply the number of staff by their average hourly rate and their average hours per week. For example, 8 staff at £12.50 an hour for 30 hours each is 8 × £12.50 × 30 = £3,000 a week. The calculator above does this and projects it to a month and a year.

What are employer on-costs?

On top of gross wages, an employer usually pays employer’s National Insurance and a minimum auto-enrolment pension contribution. For 2026-27, employer NI is 15% on earnings above a £5,000-a-year secondary threshold, and the auto-enrolment minimum employer pension is 3% of qualifying earnings (the band between £6,240 and £50,270). Together these typically add roughly 10–15% to the wage bill for a full-time employee, which is why the true cost of employment is higher than the headline pay. The Employment Allowance can offset some employer NI for eligible businesses.

What is a healthy labour cost percentage?

It varies by trade. In hospitality, labour is often targeted at around 25–35% of revenue, with the whole "prime cost" (labour plus cost of goods) kept under about 60–65%. Retail and services differ. The useful habit is watching labour cost as a live percentage of sales, not just a number at month-end.

How can I bring my wage bill down without cutting hours blindly?

The cheapest savings come from matching staffing to demand and stopping small leaks: overstaffed quiet shifts, early clock-ins, unapproved overtime and buddy-punching. WagePilot shows the live cost of the floor as people clock in, so you can see overspend while the shift is still running rather than after payroll.
