How to benchmark a salary in six steps
Start with the work, align the comparisons and finish with a documented decision. These six steps turn a collection of salary figures into a hiring range you can explain.
Define the role by its duties
Write down what the person will do, what they will be accountable for and which skills are essential on day one. Include team size, decision-making authority, technical scope and any qualifications the work requires.
Job titles are a starting point. A project manager delivering construction works and a project manager coordinating software releases may need different evidence. A broad title such as analyst can cover very different jobs.
Match the location, hours and employment basis
Use the employee's main work location and compare like working patterns. Record contracted paid hours, full-time or part-time status and whether the role is paid throughout the year. Explain how you treat a remote vacancy.
Employee annual pay, an hourly rate and a contractor day rate are different comparisons. If an NHS, school or other applicable pay framework sets the pay, start with that framework and confirm the band or range.
Choose evidence and check what it measures
Use a source that fits the role, and inspect its date, sample and pay definition. Check whether the number measures basic pay, gross annual earnings, total cash or a package including equity. Make the same checks on comparable vacancies.
ONS earnings are a useful payroll-based reference. Recruiter guides and recent adverts can add hiring context. Specialist pay surveys may offer closer job-level matches. Record why you used each source rather than averaging incompatible figures.
Review movement since the data was collected
The year in a guide's title does not tell you when its salaries were measured. Distinguish the earnings reference period from publication and update dates. Ask whether the source already includes a pay update before applying another one.
Broad industry pay growth can provide context, but it does not prove that every occupation moved by the same amount. Show any update separately and record its limitations. Cross-check important decisions against recent, comparable hiring evidence.
Choose a market position and a usable advert range
Decide what makes the vacancy sit lower, near the middle or higher within comparable pay evidence. Scarce required skills or a wider responsibility scope may affect your judgement, but a higher figure should have an explanation.
Percentiles describe the distribution of employee pay. They do not automatically translate into junior, mid-level and senior jobs. Choose the range for this vacancy and define the capabilities that would support different starting points.
Check the budget and existing staff pay
Cost the proposed salary with employer National Insurance, pension and any relevant benefits, recruitment or training costs. Compare it with employees doing similar work and examine unexplained differences before publishing.
Then document the range, source dates, pay basis, assumptions and approval. Decide who can authorise an offer within the range and what happens if a candidate needs a salary outside it.
Which salary data should you use?
Choose evidence by its fit and definition, rather than by how confident a headline sounds. Different sources answer different questions, so keep their strengths and limits visible.
| Source | Useful for | Check before using it |
|---|---|---|
| ONS ASHE | Employee earnings by occupation, region and working pattern | Broad occupation match, reference period, uncertainty and gross earnings versus basic pay |
| Recruiter salary guides | Sector-specific hiring insight and a useful cross-check | Role definitions, geography, publication date and how estimates were collected |
| Crowdsourced salary pages | Candidate perspective and initial research | Sample size, reporting dates, level mix and whether reported figures include variable pay |
| Employer surveys and platforms | Job-level matching and recurring reward decisions | Your actual UK role coverage, sample, pay components and access cost |
For a comparison of specific services, read UK salary benchmarking tools and companies compared. The right combination depends on whether you are pricing one vacancy or reviewing a whole workforce.
What salary should I advertise?
Advertise a range that you can fund and explain for the actual responsibilities of the vacancy. State basic pay clearly, align it with the working hours and describe bonus or benefits separately.
A range should help candidates understand the offer. Decide what evidence would place a successful hire at the bottom, middle or top, and make sure the upper figure is an offer you would genuinely approve. A very wide band may conceal several different roles or levels.
There is no single percentage band that suits every job. Use the evidence, internal structure and real offer discretion to set the width. Avoid treating a national lower-to-upper quartile span as the advert range by default.
For a part-time role, distinguish the full-time equivalent salary from the amount paid for the actual hours. For bonus-heavy roles, avoid presenting annual gross earnings as a basic-pay estimate. Check the applicable minimum wage using the correct working-time and pay rules; dividing annual salary by contracted hours is only an initial sense-check.

How much will the proposed salary cost the employer?
The payroll commitment includes salary plus the applicable employer NI and pension costs. A baseline calculation is useful for comparing offers, but your actual cost depends on the employee, pension scheme and available reliefs.
For a standard full-year illustration in 2026/27, employer NI is 15% of salary above £5,000. Minimum employer pension contributions on qualifying earnings are 3% of earnings between £6,240 and £50,270. Other pension contribution bases can apply.
| Gross annual salary | £37,500.00 |
|---|---|
| Standard employer NI | (£37,500 minus £5,000) × 15% = £4,875.00 |
| Minimum employer pension on qualifying earnings | (£37,500 minus £6,240) × 3% = £937.80 |
| Baseline annual employer cost | £43,312.80, or £3,609.40 a month |
Assumes standard employer NI, an employee eligible for employer pension contributions, 52 paid weeks and the minimum qualifying-earnings pension basis. Excludes Employment Allowance, special NI reliefs, enhanced pension, benefits, recruitment, equipment, training and other business costs. Payroll-period rounding may differ.
Under the same assumptions, the £35,000 lower salary costs £40,362.80 a year and the £40,000 upper salary costs £46,262.80. Cost the whole approved range, not just the midpoint, and check which additional costs rise with salary and which are fixed. Your employee cost estimate can support the budget discussion.
How do I justify a salary to finance?
Explain the role match, the pay evidence, the chosen position and the total budget in one short approval note. Make the assumptions visible so the approver can understand why this range fits the vacancy.
Attach the evidence or a report, distinguish basic pay from broader annual earnings and mention a weak match or limited sample. PayPrecise's paid vacancy report brings the range, supported hiring positions, employer-cost estimates, sources and limitations together for that discussion.
What makes a salary benchmark misleading?
A comparison becomes misleading when the jobs, pay definitions or time periods do not match. These checks catch common problems before they enter the hiring budget.
- Matching only the title: check duties, responsibility and relevant job level.
- Using the UK number unchanged for a local role: review location and the evidence behind any adjustment.
- Mixing basic salary and total cash: identify bonus, commission, overtime and allowances.
- Calling quartiles experience levels: pay distribution does not measure individual seniority.
- Updating an already updated figure: record the original reference date and any movement already applied.
- Ignoring internal pay: assess similar work and unexplained differences before making an offer.
- Confusing a benchmark with a hiring guarantee: use recent hiring feedback and the wider offer alongside salary evidence.
For national occupation reference figures, use the UK salary guide for employers. It makes the underlying pay distribution visible without presenting it as a vacancy-specific offer.
Salary benchmarking questions
What is compensation benchmarking?
Compensation benchmarking compares the reward package with external evidence. It may cover basic salary, bonus, commission, benefits or equity. State the components you are comparing; a broader package should not be compared directly with a basic-salary figure.
How often should I benchmark a salary?
Check the evidence when opening or materially changing a vacancy, and review it during your normal pay cycle. Refresh earlier if responsibilities, hiring conditions or internal pay have changed. Use source dates and relevant hiring feedback to decide whether an older figure is still suitable.
Can a small business benchmark salaries without a subscription?
Yes. Public evidence and salary guides can support an initial review, and some providers offer individual-role services. PayPrecise offers a free starting preview and a £49 report for one vacancy. Check what each option includes before paying.
Is the median the right salary for every new hire?
No. The median is the middle point in the pay distribution. The final offer also depends on the vacancy's responsibilities, required capabilities, internal pay, budget and hiring conditions.
