Choose an annual salary or hourly wage, then adjust employer contributions and overheads to see the full estimated cost.

2026/27 starting assumptions: Standard employer NI of 15% above the £5,000 annual secondary threshold, and a 3% employer workplace pension contribution on qualifying earnings between £6,240 and £50,270. These assumptions can be edited.
PAY STRUCTURE
Salary before employee Income Tax, employee NI and employee pension deductions.
Used to calculate hourly costs. In hourly mode, it also determines annual gross pay.

EMPLOYER NATIONAL INSURANCE
Eligible under-21 employees and qualifying apprentices under 25 can have a 0% employer NI band. Eligibility must be verified.
Used only for the eligible under-21 and apprentice NI categories.
WORKPLACE PENSION
Select the contribution basis used by your scheme. No contribution should only be selected when lawful.

UNDERSTANDING THE COST OF HIRING

WHY EMPLOYEES COST
MORE THAN THEIR SALARY.

When budgeting for a new employee, gross wages are only one part of the cost. Businesses may also need to pay employer National Insurance, workplace pension contributions and operational expenses associated with employing someone.

01. Gross Wages

The agreed salary or hourly pay before the employee's own tax, NI and pension deductions.

02. Employer National Insurance

An additional employer contribution calculated according to the employee's earnings, NI category and applicable thresholds.

03. Workplace Pension

Employers generally have pension duties for eligible workers. Contribution calculations depend on the pension scheme.

04. Payroll & Administration

Payroll software, administration and employment-related management costs.

05. Training & Equipment

Onboarding, work equipment, software, uniforms and professional development.

06. Productive Working Time

Paid holiday and other non-productive paid time affect the effective cost of each hour worked.

Example: Hiring Someone on £30,000 a Year

A standard employee earning £30,000 annually would have estimated employer National Insurance of £3,750 using a 15% rate above a £5,000 annual threshold.

With a 3% employer pension contribution on qualifying earnings between £6,240 and £50,270, the estimated employer pension cost is £712.80 annually.

If payroll administration costs £240 annually, training £300 and equipment £600, the total estimated employment cost is £35,602.80 per year.

That's approximately £2,966.90 per month before Employment Allowance or other adjustments.

Employer NI Rate

Adjust the employer contribution percentage used in the calculation.

NI Thresholds

Edit the annual secondary threshold and special upper threshold for eligible workers.

Pension Contributions

Change the employer contribution rate and qualifying earnings limits, or model a full-salary contribution.

FREQUENTLY ASKED QUESTIONS

UK EMPLOYEE COST
FAQS.

How much does an employee really cost in the UK?

The total depends on gross pay, employer National Insurance, pension contributions and additional employment expenses. Use this calculator to estimate those costs together.

What is the employer National Insurance rate?

For 2026/27, the standard secondary Class 1 employer NI rate is 15% on earnings above the applicable secondary threshold. Some employee categories have different thresholds.

Do employers have to pay pension contributions?

Employers have workplace pension duties for eligible workers. The minimum employer contribution is generally 3% of qualifying earnings under the standard automatic-enrolment basis. Other qualifying schemes can use different bases.

Does holiday pay add another 5.6 weeks to annual salary?

Not when paid holiday is already included in the annual salary or the 52 paid weeks used for hourly wages. The productive-hours calculation accounts for paid time not spent working without adding the same wages twice.

What is Employment Allowance?

Employment Allowance can reduce eligible employers' secondary Class 1 NI liabilities. Eligibility depends on the business and its circumstances. It is claimed at employer level, not individually for every employee.

Are apprentices cheaper to employ?

Some qualifying apprentices under 25 benefit from a zero-rate employer NI band up to a specified earnings threshold. Normal NI can apply above that threshold. Other employment costs still apply.

Does this calculate take-home pay?

No. It calculates employer costs, not employee net pay after Income Tax, employee NI and pension deductions.

Is this UK employee cost calculator free?

Yes. It is free to use with no account, registration or payment.
