What an Employee Really Costs a UK Employer in 2026/27

Employers who budget only for salary underestimate their payroll by ten to twenty percent. The gap comes from statutory costs that sit outside the employment contract: employer National Insurance, pension contributions, the Apprenticeship Levy for larger payrolls, and the everyday overheads that attach to any person on the team. This guide builds the full figure from the ground up for the 2026/27 tax year.

Start with gross salary

Take a £40,000 salary as the working example. That figure forms your baseline and remains the only number most hiring managers ever see. Everything below sits on top of it.

Employer National Insurance

Employers pay secondary Class 1 National Insurance on earnings above the secondary threshold. From 6 April 2025 the rate rose to 15 percent and the secondary threshold fell to £5,000 a year, which increased employer costs sharply compared with previous years.

On a £40,000 salary the charge applies to £35,000. Multiply by 15 percent and you get £5,250 a year. HMRC sets out the current rates and thresholds at GOV.UK: National Insurance rates and categories.

Eligible employers reduce this bill with the Employment Allowance, which now covers up to £10,500 of secondary National Insurance a year. The allowance suits smaller organisations best, because it wipes out the charge entirely on a small team. A business with four employees on £40,000 would owe £21,000 before the allowance and £10,500 after it. Public bodies and single director companies with no other employees generally cannot claim, so confirm eligibility before you rely on it.

Employer pension contributions

Automatic enrolment requires a minimum employer contribution of 3 percent of qualifying earnings, which run from £6,240 to £50,270 for 2026/27. On £40,000 the qualifying slice equals £33,760, so the minimum employer contribution comes to £1,012.80 a year.

Many employers pay more than the minimum, and many calculate on full salary rather than qualifying earnings. A 5 percent employer contribution on full pay would cost £2,000 instead, so the pension line alone can swing by £1,000 depending on scheme design. Model different contribution levels with the pension contribution calculator.

The Apprenticeship Levy

Employers with an annual pay bill above £3 million pay the Apprenticeship Levy at 0.5 percent of the pay bill, offset by a £15,000 annual allowance. A business with a £5 million pay bill therefore pays £25,000 of levy less the £15,000 allowance, leaving £10,000. Smaller employers pay nothing, which is why this line disappears from most small business budgets. The official rules sit at GOV.UK: pay Apprenticeship Levy.

The statutory subtotal

For our £40,000 hire at a smaller employer, the statutory cost stacks up as salary of £40,000, employer National Insurance of £5,250 and employer pension of £1,012.80. That produces £46,262.80 a year, which represents a 15.7 percent uplift on the headline salary before anything else joins the list.

Paid time off changes the hourly maths

Full time employees in the UK receive a statutory minimum of 5.6 weeks of paid leave, which usually means 28 days including bank holidays. Across a 52 week year the employee therefore works about 46.4 weeks while you pay for 52. On £46,262.80 of total statutory cost, each week actually worked costs roughly £997 rather than £890.

Statutory sick pay, maternity pay, paternity pay and shared parental pay add further variable cost. Employers recover 92 percent of statutory maternity pay, and small employers whose total Class 1 National Insurance came to £45,000 or less in the previous tax year recover 109 percent, so the net exposure there stays modest. Statutory sick pay carries no recovery at all. Estimate leave and statutory pay exposure with the holiday entitlement calculator and the maternity pay calculator.

Overheads and the rest of the picture

Beyond statutory obligations, most employers budget for recruitment, equipment, software licences, workspace, employers liability insurance, training and management time. These costs vary widely by sector, location and supplier, so take them from your own quotes and invoices rather than from rules of thumb. Employers liability insurance stands out, because the law requires most employers to hold it from the day they take on their first employee.

If your own overheads came to £6,000 a year for this role, for example, the first year cost of a £40,000 hire would reach £52,262.80.

Salary sacrifice cuts the bill for both sides

Salary sacrifice reduces gross pay, which reduces employer National Insurance at 15 percent as well as employee National Insurance. An employee who sacrifices £4,000 into a pension saves their employer £600 a year. Many employers share that saving back into the pension pot, which costs the business nothing and raises the value of the package. Cycle to work schemes and ultra low emission car schemes work on the same principle.

Presenting total reward to candidates

Candidates compare salary figures, not employer cost. Showing the full package clearly wins offers without raising salary. Spell out the employer pension percentage in pounds, quantify the holiday allowance in days, and put a value on private medical cover, life assurance and training budgets. A candidate weighing two offers can compare them properly with the job offer comparison calculator, and you can sense check the net pay your offer delivers with the UK salary calculator.

Statutory cost at other salary levels

The uplift on salary shifts with pay, because employer National Insurance starts so low and pension minimums stop at £50,270. Here is the statutory cost for three common salaries in 2026/27, assuming minimum pension contributions and no Employment Allowance.

A full time employee on the National Living Wage of £12.71 an hour, working 37.5 hours a week, earns £24,784.50 a year. Employer National Insurance adds £2,967.68 and the minimum pension adds £556.34. The total reaches £28,308.52, an uplift of about 14 percent.

A £25,000 salary attracts £3,000 of employer National Insurance and £562.80 of minimum pension. The total comes to £28,562.80, again an uplift of about 14 percent.

A £60,000 salary attracts £8,250 of employer National Insurance. The minimum pension caps at the top of qualifying earnings, so it costs £1,320.90. The total reaches £69,570.90, an uplift of about 16 percent. Higher salaries push the percentage up slowly, because employer National Insurance carries on at 15 percent with no upper limit while the pension minimum stays fixed.

These figures explain why the April 2025 change hit lower paid, high headcount sectors hardest. Dropping the threshold from £9,100 to £5,000 added £615 of National Insurance per employee before the rate rise even applied, and the move from 13.8 percent to 15 percent pushed the bill higher again.

A quick budgeting checklist

Before you sign off a hire, confirm the salary band, add 15 percent for employer National Insurance above £5,000, add your actual pension contribution rate, check whether the Employment Allowance still has headroom, include levy exposure if your pay bill passes £3 million, and set aside first year equipment and recruitment costs. That sequence turns a rough guess into a defensible number.

HMRC republishes every employer figure in this guide each spring in its rates and thresholds for employers guidance on GOV.UK. Check it every April before you set budgets, because thresholds, allowances and recovery rates can change with each Budget, and a stale figure multiplied across a whole team adds up quickly.
