What staff turnover actually costs — and how to work out your number
Every published figure for the cost of replacing an employee is different, because every study counts different things. The number that will change a decision in your business is the one you build from your own costs.

Key takeaways
- Published averages vary enormously because they measure different things — build your own figure from your own costs rather than borrowing a headline
- The visible costs (advertising, agency fees) are usually the smallest part; cover, training time and reduced output while someone learns cost more
- Hospitality and retail carry the highest turnover rates in the UK, so even a modest per-leaver cost compounds quickly
- Rota quality is one of the few levers you control directly — short-notice changes and unpredictable hours are consistently cited reasons for leaving shift work
Why published averages disagree
Search for the cost of replacing an employee and you will be told £3,000, £12,000, £25,000, or six to nine months of salary. None of these is wrong exactly. They are answers to different questions — some count only recruitment spend, others include lost productivity, and most are weighted towards salaried roles rather than hourly shift work.
The commonly quoted range of roughly £3,000 to £30,000 per replacement, varying by seniority and sector, is a fair illustration of the spread rather than a number to plan with. For a part-time bar role and a site manager to sit inside the same figure tells you nothing useful about either.
Use averages for direction, not decisions
A borrowed number is easy to dismiss in a meeting — someone will always say "that's not our business". A number built from your own advertising spend, your own trainer's hourly rate and your own cover costs is much harder to argue with, and it is usually bigger.
Building your own figure
Take one recent leaver in a typical role and total four buckets. Everything you need is already in your own records.
| Bucket | What to add up |
|---|---|
| Recruiting | Advertising, agency fees, and manager hours spent shortlisting and interviewing |
| Covering the gap | Overtime, agency cover, and shifts run short-staffed between the leaver going and the replacement being useful |
| Training | Induction time, the trainer's time, and any certification the role requires |
| Reduced output | The gap between a new starter's productivity and an experienced person's, until it closes |
Multiply the per-leaver total by your annual leavers. If you employ 40 people in hospitality and turnover runs at the sector norm, that is not a rounding error — it is a line item most businesses have simply never put on a page.
The costs that never get counted
The visible costs are the smallest ones. Advertising a role is cheap; running a site short for six weeks is not. The items below rarely appear in a turnover calculation and often exceed everything that does.
- Manager time. Recruiting, inducting and supervising a new starter comes out of the same hours as running the operation.
- Pressure on everyone who stayed. Cover is absorbed by your most reliable people, which is how one departure becomes two.
- Service quality. In customer-facing roles, an inexperienced shift costs revenue in ways that never get attributed to turnover.
- Errors while learning. Waste, mistakes and slower service during the first weeks.
- Knowledge that walks out. Who the regulars are, which supplier to call, what breaks on a Friday.
- Admin. Onboarding, right to work checks, final pay and the P45 — small individually, constant at volume.
The exit costs are real too, and they are the ones most likely to be handled badly under time pressure — the accrued holiday balance, notice pay and the P45 covered in final pay when someone leaves.
Why hospitality and retail feel it hardest
Turnover in UK hospitality is consistently the highest of any sector, with retail not far behind — both well above the all-industry average. That combination is what makes the arithmetic bite: a moderate per-leaver cost multiplied by a high leaver count produces a number that rivals other line items nobody would leave unmanaged.
It also means benchmarking against an all-industry figure is actively misleading. Compare yourself to your sector, and more usefully to your own sites — one venue with double the turnover of its neighbours is a specific, solvable problem, and it disappears inside a company-wide average.
The levers you actually control
You do not control the local labour market or what the pub down the road pays. You do control how predictable working here is, and in shift work that is repeatedly among the reasons people give for leaving.
- Publish rotas further ahead and change them less. Being able to plan a life around work is worth real money to people — see changing a rota.
- Handle holiday requests visibly and consistently. Perceived favouritism over dates off does disproportionate damage — the rules are in handling holiday requests.
- Fix the first fortnight. Early leavers cite confusion, not the work. Onboarding is the cheapest intervention available.
- Pay accurately and on time. Nothing corrodes trust faster than a wrong payslip, and it is entirely self-inflicted.
- Spread unpopular shifts. Open shifts offered to everyone qualified beat ringing the same three people until they leave.
Most of these are a scheduling problem before they are an HR one. Rota software that publishes further ahead and pushes changes to people's phones, holiday management that shows why an answer was given, and accurate hours reaching payroll remove three of the most common reasons shift staff give for leaving — and the free rota templates are a reasonable place to start if you are still on paper.
Make working here more predictable
Rotas published further ahead, changes pushed to the people affected, and holiday answered consistently — the levers that keep good staff.
Turnover cost figures quoted here are published third-party estimates included for illustration; they vary widely by methodology, sector and role. Build your own calculation from your own costs before relying on a number for a business decision. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.
Staff turnover questions
- Published estimates range widely — figures of roughly £3,000 to £30,000 per replacement are commonly quoted depending on seniority and sector, and some studies put specialist roles far higher. The range is so wide because each study counts different things, which is why your own calculation is worth more than any headline.
- Add four buckets for one leaver: cost to recruit, cost to cover the gap, cost to train, and the value of reduced output while the new person gets up to speed. Multiply by the number of leavers in a year. The result is usually larger than expected, and it is defensible because you built it.
- Averages across the UK sit somewhere around a third, but sector matters far more than the average — hospitality is consistently the highest, with retail close behind. Comparing yourself to an all-industry figure will flatter or alarm you for no useful reason.
- Leavers in the period divided by the average headcount over the same period, expressed as a percentage. Track it by site and by role as well as overall — one struggling venue can hide inside a healthy company-wide number.
