Summary
1
Mandatory on-costs add a tight 14% to 16%: employer NI (15% above £5,000) plus the 3% minimum pension.
2
Indirect costs add another 20% to 30%: recruitment, onboarding, equipment, overhead and management time.
3
Turnover is the hidden multiplier, an inflation-adjusted ~£42,000 per leaver, budgeted across the team.
4
The £30k example, fully loaded (with amortised turnover and full overhead) reaches the upper end, ~£47k.
5
The lever most cost-stressed SMEs are pulling: basing some roles in a lower-cost market, cutting per-role cost 40% to 60%.

01
Salary
The headline number; everything else builds on top.
02
Employer National Insurance
15% of earnings above £5,000 per employee per year (with relief for under-21s, apprentices under 25, and qualifying veterans up to £50,270).
03
Minimum pension contribution
3% of qualifying earnings (£6,240 to £50,270 in 2026/27); most employers pay more in practice to compete.
04
Statutory leave entitlement
5.6 weeks (28 days including bank holidays) of paid time off, plus statutory sick pay, maternity, paternity, and parental pay obligations.
05
Recruitment and onboarding
Agency fees of 15% to 25% of first-year salary, where used, plus advertising, internal time, equipment, software licences, and induction.
06
Turnover risk
An inflation-adjusted £42,000 per leaver on average, most of it hidden as lost productivity during ramp-up.
07
Growth and Skills Levy
0.5% of the pay bill above £3 million per year. Most SMEs do not pay it directly, but they can access the funding it generates.
08
Overhead
Office or hybrid-working costs, equipment, software, training, management time, and statutory record-keeping.
For a £30,000 employee, those layers compound to a fully-loaded first-year cost in the £41,000 to £47,000 range. For senior or specialist roles, the uplift is proportionally similar (35% to 45% above salary), but the absolute figures are larger: a £60,000 senior hire typically costs the business in the region of £82,000 to £88,000 all-in.

01Salary: the headline number that is not the true number
Salary: the headline number that is not the true number
Salary is the first cost line on any hire, the one that gets discussed in interviews, and the only one the employee actually sees on their payslip. It is also the smallest part of the true cost of an employee in the UK.
UK median full-time salaries in 2026 sit at roughly £38,500 for all employees, with substantial variation by sector, region, and seniority. Knowledge-worker roles in London and the South East run materially above the median; service-sector and regional roles run below it. The salary figure you advertise determines who applies and what they expect to be paid; it does not determine what the role costs you to fill.

The salary figure you advertise determines who applies and what they expect to be paid; it does not determine what the role costs you to fill.
Our deeper guide, The Cost of Employing Someone in the UK, walks through this gap in detail. It distinguishes between mandatory on-costs (which add a tight 14% to 16% on top of salary across most pay bands) and indirect costs (recruitment, equipment, training, workspace, management time), which typically add a further 20% to 30%. The two together produce the 35% to 45% all-in range. The guide also includes worked examples at multiple salary levels and a step-by-step calculation of what to budget for a specific hire.
| Gross salary | Employer NI | Min. pension | Mandatory on-costs | True baseline cost | On-cost as % of salary |
|---|---|---|---|---|---|
| £25,000 | £3,000 | £563 | £3,563 | £28,563 | 14.3% |
| £30,000 | £3,750 | £713 | £4,463 | £34,463 | 14.9% |

02Employer National Insurance: the largest single addition on top of salary
Employer National Insurance: the largest single addition on top of salary
Employer National Insurance is the most significant cost layered onto every UK salary, and it is also the cost that has changed the most in the last two years.
For the 2026/27 tax year, the employer rate is 15% on every pound an employee earns above the secondary threshold of £5,000 per year (HMRC, Rates and thresholds for employers 2026 to 2027).
Both the rate and the threshold are unchanged from 2026: the big increase already happened on 6 April 2025, when the rate rose from 13.8% to 15%, and the threshold fell from £9,100 to £5,000 (legislated under the National Insurance Contributions (Secondary Class 1 Contributions) Act 2025).
Those figures have carried over into 2026/27, and the Autumn Budget on 26 November 2025 extended the threshold freeze through to April 2031.
The calculation is straightforward: take the gross annual salary, subtract £5,000, and multiply by 15%. So a £30,000 employee costs £3,750 in employer NI; a £50,000 employee costs £6,750; a £70,000 employee costs £9,750. Three reliefs reduce the bill for some employers:

- Employment Allowance: eligible smaller employers can offset up to £10,500 per year of their employer's NI bill (GOV.UK, Claim Employment Allowance). This is enough to cancel the NI on roughly one or two average-salary employees entirely. Eligibility excludes sole-director companies and most public-sector employers, and connected companies must share a single allowance.
- Under-21s and apprentices under 25: employer NI is 0% on earnings up to the Upper Secondary Threshold of £50,270 for employees in these categories, applied through NI categories M and H respectively. For a £20,000 apprentice, that saves roughly £2,250 per year compared with the standard NI position, recurring for as long as the employee remains under 25.
- Qualifying veterans: similar relief applies up to £50,270 for the first 12 months of civilian employment after leaving HM Forces.
Our foundational guide, Employer National Insurance Explained, walks through the mechanism, the three classes (Class 1 on salary, Class 1A on benefits in kind, Class 1B on PAYE Settlement Agreements), how to calculate the cost, and the legitimate ways to reduce it.

03Pension contributions: the smaller but mandatory addition
Pension contributions: the smaller but mandatory addition
UK automatic enrolment requires every employer to make minimum pension contributions for eligible employees (aged 22 to State Pension age, earning at least £10,000 a year). The minimum employer contribution is 3% of qualifying earnings, which is the band of earnings between £6,240 and £50,270 in 2026/27 (The Pensions Regulator). The employee contributes a further 5%, taking total minimum contributions to 8%.
The calculation: take the salary, cap at £50,270, subtract £6,240, multiply by 3%. For a £30,000 employee, the minimum employer contribution is £713 per year ((£30,000 - £6,240) × 3%). For a £50,000 employee, it is £1,313. Because qualifying earnings are capped at £50,270, the minimum employer contribution levels off at £1,320.90 per year for any salary above that level.

£50,000 salary£1,313(£50,000 less £6,240) × 3%
£80,000 salary£1,321Capped at £50,270 ceiling
In practice, most UK employers contribute more than the minimum to compete for talent. Typical employer contributions in professional services and SaaS sit at 5% to 8%, and many employers match a higher employee contribution up to a defined ceiling. A 5% employer contribution on the same £30,000 salary lifts the cost to £1,188 per year; an 8% contribution lifts it to £1,901.
There is also a change worth knowing about ahead, even though it does not affect 2026/27. From April 2029, only the first £2,000 of an employee's pension contributions made through salary sacrifice will be exempt from National Insurance, after which both employer and employee NI will be due on the excess (House of Commons Library, CBP-10423). For employers who currently use salary sacrifice to reduce their NI bill, that relief will be capped.

04Statutory leave and pay: the productive-time cost most employers miss
Statutory leave and pay: the productive-time cost most employers miss
The fourth layer is the one that gets routinely missed because it is not a payroll line. UK employees are entitled to 5.6 weeks of paid annual leave (28 days including bank holidays for a five-day-a-week worker), plus statutory sick pay, statutory maternity pay, statutory paternity pay, and shared parental pay where applicable. The pure cash cost of these obligations is small to moderate; the productive-time cost is more substantial.
Annual leave
A 28-day entitlement on a 260-working-day year means the employee is paid for roughly 12% of the year without being at work. The salary covers both working and non-working days, so this is not an additional payroll line; it is a productivity factor that effectively turns a £30,000 salary into a cost per productive day of around £129 rather than the £115 the headline implies.
Statutory Sick Pay
For 2026/27, SSP is paid at £118.75 per week for up to 28 weeks of qualifying sickness absence. The average UK worker takes around 7 to 8 sick days per year, so the typical SSP exposure per employee is £150 to £200 per year, often less. Unlike an auto-enrolment pension, SSP can be a meaningful cost only in the rare cases of extended absence.
Statutory parental pay
Statutory Maternity Pay is paid at 90% of weekly earnings for the first 6 weeks, then £187.18 per week (or 90% of earnings if lower) for the next 33 weeks. Most of this can be reclaimed from HMRC by employers (92%, or 103% for small employers eligible for Small Employers' Relief), so the net employer cost is typically modest. Statutory Paternity Pay and Shared Parental Pay follow similar reclaim arrangements. For an SME that hires a relatively small team, the parental pay exposure is real but variable; budgeting in the region of £500 to £2,000 per year, averaged across the team, is a reasonable working assumption.
The higher cost of parental leave is the operational disruption (covering the role, lost continuity, managing the return) rather than the statutory pay itself. For workforce planning, the assumption to build in is that an average team will lose roughly 2% to 4% of productive time per year to a mix of parental leave, long-term sickness, and other extended absence, on top of the 12% paid annual leave.
Treated together, statutory leave and pay obligations do not add a dramatic line to the cost stack on a per-employee basis, but they reduce productive working time by 15% to 20% of the calendar year, which is the consideration that matters most when calibrating how much output a salary actually buys.
05Recruitment and onboarding: the cost of getting the employee in the seat
Recruitment and onboarding: the cost of getting the employee in the seat
Before the employee starts producing any value, you have already spent significant time and money getting them through the door. Recruitment and onboarding is the cost of acquisition: it sits in year one of every new hire and is often the second-largest line on the cost stack after employer NI.
Recruitment agency fees are the most visible component when used. UK recruitment agencies typically charge 15% to 25% of the employee's first-year salary for standard permanent placements, 25% to 30% for senior or specialist roles, and 30% to 35% for niche executive search. For a £30,000 hire at a 20% agency fee, that is £6,000 in agency cost alone. For a £60,000 senior hire at 25%, it is £15,000.

Our deeper guide, Recruitment Agency Fees in the UK, sets out the four main fee models (contingency, retained search, fixed or flat fee, RPO), the difference between permanent and temporary or contract pricing, the rebate periods to expect when a candidate leaves early (typically 100% in weeks 1-4, sliding to nil after week 12), what is included as standard and what is usually extra, and the legal position on charging candidates (UK employment agencies are prohibited from charging work-seekers).
Pay on hire
Contingency
You pay only when a candidate is placed. The fee is a percentage of first-year salary, and it is the standard model for permanent recruitment.
Retainer
Retained search
You pay only when a candidate is placed. The fee is a percentage of first-year salary, and it is the standard model for permanent recruitment.

RPO

Direct recruitment costs beyond agency fees include job board advertising (LinkedIn Recruiter licences, paid job posts on Indeed and equivalent), assessment tooling, reference and background checks, and the time of internal staff running the hiring process. A typical mid-level hire absorbs 20 to 40 hours of internal management time in screening, interviewing, and decision-making, which carries its own cost.
Onboarding adds equipment provision (laptop, monitor, peripherals at £1,200 to £2,500 per starter), software licences and seat fees, induction training, mandatory compliance training (data protection, anti-bribery, health and safety), and role-specific upskilling. The first three months of a new hire's salary are typically partially offset by lower productivity, which compounds the cost.
Putting the components together, recruitment and onboarding for a typical mid-level hire lands in the £5,000 to £12,000 range all-in for year one, before any agency fee, plus the agency fee on top if one is used. Amortised across an expected three-year tenure, that is roughly £2,000 to £4,000 per year of recurring cost loading on top of the salary.

06Turnover: the cost that only shows up when it happens
Turnover: the cost that only shows up when it happens
Turnover is the cost that hides best, which is why most businesses underestimate it. The most widely cited UK research, by Oxford Economics and Unum in 2014, put the average cost of replacing an employee at £30,614, around £42,000 once adjusted for inflation to 2026 levels. The majority of that is hidden: roughly £25,000 is lost productivity while a replacement gets up to speed (the study found new hires take an average of 28 weeks to reach full effectiveness), with only around £5,400 going on the visible costs of advertising, agencies, and onboarding.
More recent estimates land in a similar broad range. Culture Amp's 2025 UK attrition research puts the cost of replacing an employee at 30% to 200% of annual salary, depending on seniority and performance level, which, on the UK 2024 average salary of £37,430, translates to roughly £11,000 to £75,000 per departure. PayFit's 2025 industry report puts the average UK replacement cost at £25,000 to £30,000 for typical roles and £40,000 to £100,000 for senior or specialist hires.
The turnover cost only shows up when someone leaves, but it should be budgeted on an expected basis from day one. The calculation: estimate your turnover rate (CIPD UK average is around 34% across all sectors, with substantial variation from 25% in public administration to over 50% in hospitality), multiply by your team size to get expected leavers per year, and multiply by the cost per replacement. For a 30-person team at 17% turnover and £42,000 cost per leaver, the expected annual turnover cost is 5 leavers × £42,000 = £210,000 per year, the equivalent of around seven full salaries lost to churn.

07The Growth and Skills Levy: applicable only to larger employers
The Growth and Skills Levy: applicable only to larger employers
The seventh layer is the one that does not apply to most SMEs, but should be understood by every UK employer. The Growth and Skills Levy (the renamed Apprenticeship Levy, effective from 1 April 2026) is charged at 0.5% of the annual pay bill for employers whose UK pay bill exceeds £3 million per year. A £15,000 annual allowance offsets the first £15,000 of levy due, so businesses that pay bills at or below £3 million pay nothing. A smaller share of UK businesses are large enough to pay; most SMEs are below the threshold.
| Annual UK pay bill | 0.5% gross levy | Less £15,000 allowance | Annual levy due |
|---|---|---|---|
| £3,000,000 | £15,000 | £15,000 | £0 |
| £4,000,000 | £20,000 | £15,000 | £5,000 |
| £5,000,000 | £25,000 | £15,000 | £10,000 |
| £10,000,000 | £50,000 | £15,000 | £35,000 |
| £20,000,000 | £100,000 | £15,000 | £85,000 |
For employers above the threshold, the levy is collected monthly through PAYE alongside Income Tax and National Insurance, and funds are credited to the employer's Apprenticeship Service account for use on apprenticeship training. From 1 August 2026, up to 50% of levy funds can be used on shorter modular apprenticeship units (one week to 16 weeks), with the remainder reserved for full apprenticeship programmes. Levy funds expire 12 months after they were contributed (down from 24 months), so employers need to commit them faster.
For SMEs that do not pay the levy, the relevant point is the funding they can access on the other side: government co-investment covers 95% of approved apprenticeship training costs (rising to 100% for under-22s, and from August 2026, 100% for all under-25s at SMEs), plus several incentive payments for hiring apprentices in younger age groups, and from June 2026 a £3,000 Youth Jobs Grant for hiring 18-24 year-olds who have been on Universal Credit for at least six months. The under-25 employer NI exemption discussed in Section 2 sits on top of all of this, and across a typical three-year apprenticeship is often the largest financial line of all.

08The full cost stack, assembled: a worked example
The full cost stack, assembled: a worked example
Pulling every layer together, here is what a typical UK hire actually costs in 2026, using a £30,000 mid-level employee as the worked example.
| Cost layer | Annual cost | Notes |
|---|---|---|
| Base salary | £30,000 | The headline figure |
| Employer National Insurance | £3,750 | 15% on £25,000 (earnings above £5,000) |
| Minimum employer pension (3%) | £713 | 3% on £23,760 (earnings between £6,240 and £50,270) |
| Recruitment, amortised over 3 years | £1,500 to £3,000 | Agency fee plus internal time, equipment, onboarding |
| Equipment, software, training | £1,500 to £3,000 | Laptop, software licences, ongoing training |
| Turnover risk (15% rate × £42,000 cost) | £6,300 | Amortised expected cost across the team |
| Office, statutory record-keeping, overhead | £1,500 to £3,000 | Per-employee share of fixed overhead |
| All-in annual cost | £45,263 to £49,763 | 51% to 66% above the salary figure |
For a more conservative assumption (lower turnover rate, no agency, lean overhead, no office), the lower bound on the same £30,000 salary lands closer to £41,000 (a 37% uplift). The 35% to 45% range cited at the top of this guide is the realistic mid-point for a typical UK SME hiring through normal channels and is the number to budget against. The 51% to 66% upper bound above is the comprehensive assumption that includes amortised turnover risk and full overhead.
The pattern scales proportionally with salary. For a £60,000 senior hire, the same uplift produces an all-in cost in the £82,000 to £88,000 range. For a £100,000 senior or specialist hire, it is £135,000 to £150,000.
For workforce planning, the fastest way to convert a hiring plan into a credible budget is to run the calculation per role rather than across averages. Our Employee Cost Calculator (UK) will let you run this calculation for any salary and assumption set instantly, with the cost stack shown line by line. In the meantime, the worked example above and the Employer National Insurance Calculator linked from Section 2 give you the two most material lines.

09Why this question has become urgent in 2026
Why this question has become urgent in 2026
The true cost of an employee has always been higher than the salary. What has changed in 2026 is that the gap has widened materially, and the trajectory points to further structural increases rather than relief.
The April 2025 employer NI increase (rate from 13.8% to 15%, threshold from £9,100 to £5,000) was the single largest change to UK employment costs in over a decade. For an employee on the UK median salary, the combined effect was to add roughly £1,250 per year of employer NI in one move (House of Commons Library, CBP-10237). For a 30-person team on average salaries, that single change added roughly £37,500 of recurring annual cost.
The threshold freeze to April 2031, announced in the Autumn Budget on 26 November 2025, locks in the cost trajectory. As UK wages rise each year against a fixed £5,000 secondary threshold, fiscal drag means a larger share of every salary sits above the threshold and attracts the 15% charge. The headline rate does not need to rise for the effective cost of UK employment to keep rising.
The pension salary-sacrifice cap from April 2029 removes one of the few remaining ways employers reduce their NI bill on pension contributions, with only the first £2,000 of salary-sacrificed pension contributions exempt from NI from that date.
The continued rise in apprenticeship and minimum wage rates through 2025 and 2026 has tightened the floor on entry-level pay, which feeds through into salary inflation higher up the structure.
And recruitment costs have stayed elevated through 2025-26 as the UK labour market for skilled roles has remained competitive despite slower headline employment growth, with agency fees holding at the 15% to 25% range for typical mid-level roles.
The combined effect is that UK employment is structurally more expensive in 2026 than it was in 2024, the trajectory is rising rather than easing, and the cost gap between salary and total employment cost is wider than at any point in the last decade. For a cost-stressed SME founder, the implication is that the cost of an employee matters more than it ever has, and the case for budgeting against the real number rather than the salary number is now operational rather than theoretical.

10What to do about it
What to do about it
Once you can see the true cost of an employee in the UK per hire, three practical options sit on the table. They are not mutually exclusive, but they are honestly different choices.
Option 1
Absorb the increased cost
For businesses with strong gross margins, growing pricing power, or specific competitive reasons to keep all roles UK-based, the simplest response is to accept the structurally higher cost and pass it through to pricing where possible. This is the right answer for some businesses, but not for many. SMEs with thin margins, price-sensitive customers, or roles that do not need to be UK-based often find this option means slower hiring rather than continued growth.
Option 2
Reduce the headcount cost base
Slow hiring, increase automation, restructure roles, defer marginal hires. This is the route most cost-stressed SMEs default to first, and it can incur high costs. The risk is that it constrains growth and shifts pressure onto existing employees, which (per Section 6) increases turnover risk, which raises the per-hire cost of the people you do retain.
Option 3
Rethink where roles are based
For roles that can be performed remotely and integrated into a UK-led team, hiring in a lower-cost market through an Employer of Record (EOR) reduces the per-employee cost by 40% to 60% on a like-for-like basis, with full compliance and no requirement to set up a local entity.
Two Legends EOR clients show what Option 3 looks like in practice.
63%
like-for-like saving
Funding Bay
Funding Bay, a London business finance brokerage, found that hiring in UK financial services was both expensive and hard to scale. Working with Legends EOR, the business built specialised marketing and business development teams in Cape Town, employed compliantly through an EOR with on-site office space and IT support. The result: an average like-for-like cost saving of 63%, and a tripling of UK turnover over two years on a substantially reduced cost base.
47%
like-for-like saving
Reduce the headcount cost base
ThinkLocum, a UK medical recruitment agency in Birmingham, took a similar route for its back-office functions. The agency built a team of six in South Africa through Legends EOR, employed compliantly under local law with no UK entity to maintain, and achieved an average like-for-like cost saving of 47% while preserving full compliance and stable retention.
For both businesses, the route started with the same step you have just taken: seeing the true cost of an employee in the UK per hire and asking which roles needed to carry it. To run the comparison for your own roles, the Legends EOR Salary Benchmarking Tool shows current SA salaries in pounds sterling for specific roles, with the EOR fee included.
