How to Benchmark a Salary for a Vacancy

Salary benchmarking compares a vacancy with relevant market evidence so a recruiter or employer can set a defensible compensation range. The difficult part is rarely finding a number. It is deciding whether the number describes the same role, location, seniority and type of compensation.

This guide provides a repeatable method. The result should be treated as a documented market estimate, not a guarantee of what every candidate will accept.

What salary benchmarking should answer

A useful benchmark answers five questions:

1. What work and level are being priced?
2. Which labour market is relevant?
3. Which compensation elements are included?
4. Which sources support the range?
5. Which assumptions could change the recommendation?

If the result cannot answer those questions, it is only a number without enough context to advise a client or candidate.

Step 1: define the role before looking at salary data

Start with the vacancy, not a salary website. Record:

• Main outcomes and responsibilities
• Required experience and decision scope
• Individual contributor or management responsibility
• Essential technical, professional or regulatory requirements
• Location and expected workplace pattern
• Permanent, fixed-term, contract or temporary status
• Full-time or part-time basis
• Base salary, bonus, commission, equity and benefits

Job title alone is not enough. “Product Manager”, “Account Manager” or “Data Engineer” can describe different levels and scopes across employers.

Use the similar job title generator to identify possible equivalents, then check each title against responsibilities rather than treating every suggestion as interchangeable.

Step 2: choose the relevant labour market

The correct geography depends on where the employer competes for talent.

• A site-based role may need a local or commuting-area benchmark.
• A nationally remote role may compete across a country.
• A scarce specialist role may compete internationally.
• A hybrid role may sit between local and national markets.

Do not apply a national figure mechanically to a vacancy with a much narrower or broader talent pool. Record the geography used and why.

Step 3: match the occupation and seniority

Compare the vacancy with source categories based on work performed. Check:

• Responsibilities and output
• Complexity and autonomy
• Team or budget responsibility
• Years of experience only where it reflects genuine level
• Required qualifications
• Industry-specific knowledge

When a source uses a broad occupation, state that limitation. A precise-looking percentile from a weak role match is less useful than a wider range from a credible match.

Step 4: gather evidence from several source types

Official labour statistics

Official statistics provide transparent definitions and broad market coverage.

For the United Kingdom, the Office for National Statistics describes the Annual Survey of Hours and Earnings as a source of pay and hours data across occupations, industries and areas.

For the United States, the Bureau of Labor Statistics Occupational Employment and Wage Statistics programme publishes annual wage estimates by occupation, geography and industry.

Official datasets may use broad occupation codes and can lag fast-changing specialist markets. Use them as a foundation, not the only source.

Current job advertisements

Job advertisements can provide recent evidence when they publish compensation. Capture the role, location, date, salary basis and whether the responsibilities genuinely match.

Advertised ranges may be broad, incomplete or influenced by legal disclosure requirements. Avoid treating the midpoint of every advert as the market rate.

Specialist salary surveys

Industry, profession and recruitment surveys can add detail for niche roles. Review the methodology, sample, geography, collection period and definition of compensation before using a headline figure.

Placement and offer data

Your own completed placements, accepted offers and declined-offer reasons can be highly relevant when the data is recent and consistently recorded. Protect candidate confidentiality and avoid drawing conclusions from very small samples.

Compensation platforms

Salary benchmarking tools can make research faster, especially when they show sources and allow role and location adjustments. Compare their data coverage and methodology in the salary benchmarking tools guide.

You can also use the free salary benchmarking tool to generate an indicative range with sources to review.

Step 5: normalise the figures

Put the evidence on a comparable basis.

Time basis

Convert hourly, daily, monthly and annual figures carefully. Record working days or hours used in any conversion rather than hiding them inside a calculation.

Base versus total compensation

Do not mix base salary with on-target earnings or total compensation. Separate:

• Base salary
• Guaranteed allowances
• Target bonus or commission
• Maximum variable compensation
• Equity
• Employer pension or retirement contribution
• Other material benefits

Currency and date

Record the currency, exchange-rate date and data reference period. Avoid implying precision when exchange rates or inflation materially affect the comparison.

Permanent versus contract

A contract day rate is not directly comparable with permanent salary. Employment taxes, paid leave, benefits, assignment risk and utilisation all matter.

Step 6: identify a market range

Do not average every number automatically. First remove or flag evidence that is:

• For a materially different role
• From the wrong location
• Based on total compensation when you need base salary
• Too old for the market being assessed
• Missing a clear methodology
• A duplicate of another underlying source

Then describe the centre and spread of the credible observations. When sample data is available, median and percentiles are often more informative than a simple average. When the evidence is sparse, use a wider range and make the uncertainty explicit.

Step 7: place the vacancy within the range

The benchmark describes the market. The recommended range also reflects the vacancy.

Consider placing a role higher in the market range when it requires scarce evidence, has unusually broad scope or competes with stronger-paying industries. Consider the lower part only when the role genuinely has narrower scope or supports development at that level.

Do not compensate for a weak proposition by changing the benchmark. Instead, state the gap between the proposed package and the evidence.

Step 8: document the recommendation

A concise salary benchmark should include:

• Role and level assessed
• Location and employment basis
• Recommended base salary range
• Variable compensation and benefits considered separately
• Source list with dates
• Role-matching notes
• Key assumptions
• Evidence excluded and why
• Review date

This makes the advice easier to challenge constructively and update later.

Example salary benchmarking worksheet

Evidence	Role match	Location match	Compensation basis	Recency	Use
Official occupation data	Medium	Strong	Base/gross pay	Annual	Market anchor
Three comparable adverts	Strong	Strong	Base salary	Current	Current hiring signal
Specialist survey	Strong	Medium	Base plus bonus	Recent	Sector context
Recent placements	Strong	Strong	Accepted base salary	Current	Direct market evidence

The table should contain actual source links and figures in a working document. The example shows the judgement fields needed to avoid combining unlike evidence.

Common salary benchmarking mistakes

Matching on title only

Check scope, level and required outcomes. Similar titles do not guarantee comparable work.

Using one source

Every source has coverage limits. Triangulate official data, current market evidence and relevant first-party outcomes where possible.

Hiding compensation definitions

State whether the range refers to base salary, guaranteed cash, on-target earnings or total compensation.

Ignoring sample and methodology

A figure without collection period, geography or sample information should carry less weight.

Presenting a range as certainty

Candidate expectations, employer brand, flexibility, benefits and hiring urgency can all affect the offer needed to close a particular hire.

Failing to refresh the benchmark

Record a review date. Refresh more frequently for volatile or scarce markets, and whenever the role scope changes.

Salary benchmarking FAQ

How many sources should a recruiter use?

There is no fixed number. Use enough independent evidence to understand the range and its limitations. Three credible, relevant sources may be more useful than ten loosely matched ones.

Should a vacancy use the market median?

Not automatically. The appropriate position depends on the organisation's compensation approach and the role's scope, scarcity and candidate market. Explain the decision rather than selecting a percentile by habit.

Can advertised salaries be used for benchmarking?

Yes, as one source. Confirm the advert is current, comparable and clear about the compensation basis. Advertised ranges show employer intent, not necessarily accepted offers.

How often should salary benchmarks be updated?

Set a review date based on market volatility and hiring frequency. Refresh when the location, responsibilities, seniority or compensation structure changes.

Is salary benchmarking legal advice?

No. Pay transparency, equal-pay and employment requirements vary by jurisdiction. Employers should obtain appropriate legal or HR advice for their circumstances.

Make the assumptions visible

Good salary benchmarking is traceable. Define the vacancy, compare like with like, review several source types and show where judgement was applied. That produces a range a recruiter can explain instead of a number that merely looks precise.
