Employee Cost Calculator UK 2026/27

Rates and data last verified 15 September 2026 by the ExpertSure editorial team. Sources are listed in the methodology below the calculator.

An employee earning £30,000 costs an estimated £34,462.80 a year in salary, standard employer National Insurance and a 3% employer pension on qualifying earnings. That is £2,871.90 a month before benefits and other business overheads. The example uses 2026/27 rates and assumes no Employment Allowance. Change the inputs below to match your pay and pension scheme.

This calculator estimates payroll costs for a standard employee, or a group on the same pay and benefits. It includes salary, employer NI, pension contributions and an optional benefits budget. Recruitment, training, equipment, premises and tax on benefits are outside the calculation. Those costs belong in your hiring budget too, but a fixed industry percentage would not tell you what your business will actually spend.

How to Use the Employee Cost Calculator

Enter actual annual gross pay, then select the pension basis used by your scheme. For part-time staff, enter their part-time annual pay, not the full-time equivalent. Include regular pay that your payroll treats as earnings. The estimate uses annual thresholds; the amount your payroll calculates each month can differ because of pay periods, rounding and changes in pay.

Choose full-time or part-time employment. The self-employed contractor option is a limited fee comparison: it excludes employee NI and pension costs only on the assumption that the person is genuinely self-employed and outside off-payroll rules. It cannot decide a worker’s status. If the engagement is inside those rules, use the appropriate payroll treatment rather than treating it as a tax-free saving.

Set your employer pension percentage. The default is 3% on qualifying earnings, with an option to use full gross salary if that matches your scheme. Enter 0 only where no employer pension contribution applies. The tool does not assess the employee’s age, pension membership, opt-in rights or eligibility; use the contribution you are actually required or have agreed to pay.

Select an optional annual benefits budget of £500 or £2,000, or choose none. These are illustrative budgets, not market prices or an average benefits package. They are added once per employee and do not include any employer tax due on the benefits. Enter the number of employees only when everyone in that group has the same salary, pension rate and benefits budget.

Select Employment Allowance only after checking eligibility. The unused-allowance input lets you reserve part of the annual relief for staff or payroll costs outside this group. It is ignored when you select Not claiming. For groups with different salaries, calculate them separately and allocate the remaining allowance between them; do not give every calculation the full annual relief.

What the £30,000 Example Includes

The default example adds £3,750 employer NI and £712.80 employer pension to the salary. It assumes a standard employee, a full year of pay, qualifying-earnings pension contributions, no benefits budget and no Employment Allowance. These assumptions make the result reproducible rather than an unspecified percentage uplift.

If your scheme instead pays 3% on the whole salary, pension cost becomes £900 and the annual total becomes £34,650. Both results can be appropriate for different schemes. The previous calculator used the full-salary calculation while describing it as the auto-enrolment minimum; the pension-basis selector now makes the distinction explicit.

Employer NI and Pension Rules for 2026/27

The standard employer NI calculation uses 15% above the £5,000 annual secondary threshold. These figures are unchanged from 2025/26. The tool’s comparison therefore shows no rate-driven increase between those two years at the same salary. The higher costs introduced in April 2025 were a change from 2024/25, not a new increase in 2026/27. See HMRC’s employer rates and thresholds for the applicable categories and pay-period limits.

The standard calculation is not suitable for every worker. Different employer NI reliefs can apply to eligible younger employees, apprentices, veterans and designated-location employment. Directors can also require a different payroll calculation method. Those categories are not modelled here. For a separate standard-NI breakdown, use our employer NIC calculator, then confirm special cases in your payroll software.

For the usual minimum-contribution pension calculation, qualifying annual earnings run from £6,240 to £50,270 in 2026/27. The calculator applies your contribution rate only to pay inside that band. At £60,000 salary, a 3% contribution on qualifying earnings is £1,320.90, rather than 3% of the entire salary. A full-salary scheme gives a different answer. The Pensions Regulator explains how the contribution basis depends on your scheme.

Employee income tax, employee NI and the employee’s own pension deduction are not extra employer costs on top of gross salary in this model. Adding those deductions again would double count part of the pay. The employer pension contribution is a separate cost. Salary-sacrifice arrangements can change the pay used for NI and pension calculations; this tool does not model those arrangements automatically.

How Employment Allowance Changes the Result

An eligible employer can use up to £10,500 of Employment Allowance against its annual employer NI bill. This is a shared allowance, not a discount for each employee. The tool limits relief to the employer NI generated by the group and to the unused allowance you enter. It never deducts more than the group’s NI bill or uses the allowance against salary, pension or benefits.

For four employees each earning £30,000, standard employer NI is £15,000 before relief. Applying the full £10,500 allowance leaves £4,500 employer NI across the group. With a 3% qualifying-earnings pension and no benefits budget, the group’s estimated annual payroll cost is £127,351.20. If another group has already used some relief, enter only what remains.

The former £100,000 employer-NI eligibility limit was removed in April 2025. Other restrictions still apply. For example, a company cannot claim where its sole director is its only employee liable for secondary Class 1 NI; connected companies and multiple payrolls also have allocation rules. Read HMRC’s Employment Allowance eligibility guidance before selecting Claiming. The calculator does not make an eligibility decision.

Build a Hiring Budget Beyond Payroll

The calculator result is a payroll estimate, not the complete cost of a hire. Add the actual costs your business expects to incur. Separate one-off recruitment and setup expenses from recurring annual expenses so that you can compare the first year with subsequent years. Keep supplier quotes and internal budgets alongside the calculation instead of applying a generic overhead multiplier.

Paid leave is already part of a salaried employee’s annual salary. If you need temporary cover or overtime while someone is away, budget for that extra spending separately. The displayed weekly and daily figures divide annual cost by 52 and 260 respectively. They are budgeting averages, not a calculation of productive hours, holiday-cover costs or a legal payroll rate.

Before deciding that a contractor is cheaper, compare the quoted fees over the period you actually need help and check employment status. The label on a contract does not settle the tax treatment. Where off-payroll working rules apply, employer responsibilities can differ from the independent-contractor assumption used by the tool. It does not include VAT, agency margins or a contractor’s own business costs.

Use the Estimate to Compare Hiring Options

Change one input at a time to see which decision changes the budget. Compare the actual salary for a part-time role with a full-time role, the pension basis your scheme uses, and the allowance still available. Save the inputs with the result so that another person can reproduce it. A more generous pension or benefits budget is a deliberate spending choice, not an unexplained hidden-cost estimate.

Payroll and HR software can help administer the rules, but a subscription does not remove the employer’s contribution obligations. Compare the features you need, including payroll integration, pension submissions and employee records. Our HR software comparison and payroll software guide explain the available options. Check current supplier pricing against your headcount before buying.

Related Calculators and Methodology
