What Is Salary Benchmarking?
Salary benchmarking compares your pay levels to the external market. Learn how to use it to attract and retain talent without overpaying.
Key Takeaways
- Salary benchmarking compares your pay rates to what the market pays for equivalent roles
- Aim to position at the 50th percentile (median) or above for roles critical to competitive advantage
- Total compensation (base + bonus + equity + benefits) matters more than base salary alone
- Update benchmarks at least annually — markets move quickly especially in tech and finance
What salary benchmarking is
Salary benchmarking is the process of comparing your organisation's pay rates for specific roles to what the external market is paying for equivalent positions. The goal is to ensure you are paying competitively enough to attract and retain the talent you need, without overpaying to the point where compensation costs undermine financial sustainability. Benchmarking creates the foundation for a transparent, defensible compensation philosophy rather than ad hoc pay decisions made on the basis of whoever negotiated hardest.
Percentile positioning
Salary benchmarks are expressed in percentiles — the 25th (bottom quarter), 50th (median — half pay more, half pay less), 75th (top quarter), and 90th (top 10%). Most organisations aim to position at a specific percentile — typically 50th for standard roles and 75th for roles critical to competitive advantage. Positioning at the 25th percentile makes hiring harder and increases turnover. Positioning at the 90th across the board is expensive and typically unnecessary.
Data sources
Reliable UK salary benchmarks come from: dedicated compensation surveys (Willis Towers Watson, Mercer, Radford — expensive but data-rich), sector-specific surveys published by industry bodies, job board data aggregators (Glassdoor, LinkedIn Salary, Totaljobs), and recruitment agencies sharing market intelligence. For SMEs, a pragmatic approach combines two or three free sources with anecdotal data from recent hiring processes — what candidates are currently earning or expecting.
Total compensation vs base salary
Benchmarking should cover total compensation, not just base salary. Benefits — healthcare, pension above statutory minimums, life insurance, enhanced parental leave — have real monetary value. Equity (share options or EMI schemes) can represent substantial future value for early employees. Flexibility and remote working have taken on monetary value post-pandemic. A company paying 50th percentile base salary with excellent benefits and equity may be more competitive than one at 75th percentile base with no additional benefits.
Building a pay philosophy
Beyond the mechanics of benchmarking, organisations benefit from an explicit pay philosophy — a clear statement of how and why compensation is set the way it is. For example: we aim to pay the 60th percentile of the London market for each role, with 20% above standard for roles directly driving our competitive advantage, because fair and competitive pay keeps people focused on their work. A clear philosophy makes pay decisions faster, reduces pay equity risks, and can be communicated to employees and candidates as part of your employer value proposition.
