Companies lose talent without salary benchmarking because pay drifts away from the market, and nobody notices until someone resigns or turns down an offer. Salary benchmarking compares what you pay with current market data for comparable roles, so you can spot gaps early and set ranges with evidence. The best practice is to make this a repeatable process, reviewing roles at least once a year and adjusting salaries accordingly.
Main Takeaways:
- 78% of employees would consider leaving for higher pay, and it would take an increase of around 16.7% to move the average person.
- Replacing one employee could cost between half and twice their annual salary.
- Around 75% of companies blend two or three data sources when benchmarking a role, which gives more reliable data than relying on one.
- Annual reviews are the standard baseline, and 27% of companies now review pay twice a year.
- Benchmarking can be tailored by region, sector and job catalogue, which matters most for specialist and technical roles.
Most companies find that their salaries have fallen behind the market, but without an obvious reason. Some tell-tale signs include a strong candidate declining an offer, a reliable employee handing in their notice, or a job opening remaining vacant for months. These signs indicate that you’re likely failing to verify your figures against the current market rates.
Salary benchmarking gives you an outside view of your pay before the market gives you one the hard way. The sections below look at why talent walks when benchmarking is missing, what that costs you, and how to build a process that catches problems early.
Why do employees leave when pay drifts away from the market?
The market moves a little every quarter, but some salary bands don’t move along with this and stay where they were set, creating a distance between the two that grows over time without anyone raising a flag. Typically, the first people to notice are your employees and potential candidates, because they will see advertised salaries, talk to former colleagues and might have received field messages from recruiters.
BambooHR’s 2026 compensation research found that 78% of employees would consider leaving for higher pay, and that a 16.7% increase would be needed to persuade the average person to leave. The second number shows that a small gap may not cost you anything, but a gap approaching that size may give your competitors an advantage. The same research found that 51% of employees would stay in a job they dislike if the salary were high enough, so compensation retains people just as much as it might push them out. In the UK, 38% of employees expect to look for a new role within 12 months, and the average worker considers a 6.9% pay rise fair this year.
Compensation is also easy to miss in exit interviews. People leaving for a better offer often give a gentler reason. When the same role keeps losing people, pay is usually part of the story, even if exit feedback points somewhere else. Without benchmarking data, you have no way to test that suspicion, so the problem carries on.
What does losing talent actually cost?
Gallup estimates that replacing one employee costs between half and twice their annual salary and describes even that range as conservative. Apply this to a $70,000 role, and a single departure could cost anywhere between $35,000 and $140,000. The higher end tends to apply to specialist and senior positions, whose knowledge takes months to rebuild.
Those figures take in the direct costs of finding someone new, along with the output you lose while the role is vacant, and the new starter finds their feet. Set against that, benchmarking roles is a small outlay.
Contractor rates also need attention. Paying above the market wastes budget, and paying below it makes it hard to attract or keep specialists on your projects. Our piece on spotting contractor overspend covers that side of the workforce in more detail.
What is salary benchmarking?
Salary benchmarking is the process of comparing what you pay for a role against the current market data for comparable roles. Good compensation takes into account job content, seniority, location, sector, and company size, so you are comparing like with like. You might also hear it called pay or compensation benchmarking, and when the workers in question are contractors, rate benchmarking.
From a benchmarking report, you get a clear picture of where each role sits in the market and what you might need to change. At NES Advantage, our salary benchmarking services produce tailored reports for a particular region or sector or are built around your own job catalogue. Our research team blends data from job boards and sector salary databases with our own proprietary research, and our consultants add their market intelligence. Subject matter experts then review the findings before they go to your executive sponsor for approval.

How do salary benchmarking tools help companies set competitive pay scales?
A salary benchmark tool takes the guesswork out of the numbers. You match each of your roles to comparable roles in the data, and the tool shows where your pay falls relative to the market median and the range around it. From there, you can set ranges for each job on the basis of evidence, and you can defend this when a manager, candidate, or a finance director questions them.
The quality of the match decides how useful the result is. Two people with the same job title can be doing different work, so a tool that matches on title alone will give you tidy but misleading answers. Compensation teams know this. In CompTool’s survey, roughly 75% of companies said they use two or three data sources per role, and only one in five relies on a single source. Cross-checking catches the outliers that any one dataset will throw up, particularly for niche jobs where samples are thin.
Costs of completing salary surveys using internal-use subscription tools can also be quite high. That’s why many companies choose to work with salary benchmarking firms and buy the finished analysis rather than manage the subscriptions themselves.
A word of caution on how you use the results: Paying above the market for every role pushes costs up without necessarily improving retention, and it tends to push market data upward as other employers do the same. The better approach is to adjust the roles that have fallen behind and keep others steady where you are already in range.
Can salary benchmarking tools be customised for different industries?
Yes, and they should be. Salaries for the same role can look very different depending on the sector, the region, and the size of the company hiring. We recommend comparing yourself with companies you recruit from and lose people to, ideally, close matches for your location and sector. A generic national average can blur everything.
Customisation is especially important for technical and specialist fields, where job families are narrow and broad surveys can be thin. A tailored approach lets you scope around the roles that concern you, the markets you hire in and the peers to compete with. We build our reports this way at NES Advantage. The work starts with a conversation about your objectives, the number and type of roles to analyse, and the experience and responsibility levels involved, so the market comparison reflects your business.
How to conduct salary benchmarking
If you want to run the process yourself, the order of work matters more than the tooling.
- Start with scope: Decide which roles you are benchmarking and why, because trying to cover every job in the business at once tends to stall. Stagger roles across review cycles and stay flexible when a particular skill set becomes scarce.
- Next is the data: Choose sources that reflect the markets and peers you compete with and gather more than one, so you can cross-check them. Match roles to what people actually do, since a title alone can be misleading.
- Bring in expert review: Someone who knows the sector should sanity-check the matches and results before anyone acts on them.
- Record the process: Recording the sources and methodology for each decision will make the next round faster and give you an audit trail if anyone asks how a range was set.
- Act on the results: Where a role is below market, you can close the gap in one go or phase the increase over time, depending on budget.
How often should companies conduct salary reviews?
Once a year is the sensible baseline. In CompTool’s survey, nearly two-thirds of respondents check the accuracy of their market matches every 12 months, and every 24 months is the next most common at 17.6%. You might need to complete off-cycle reviews when something urgent arises, such as a role that keeps losing people and needs investigation. Ravio reports that 27% of companies now run a bi-annual pay review, which suits businesses that are growing quickly or hiring in fast-changing markets.
Some situations might justify going earlier than your calendar says. For example, a move into a new market is one trigger, and a spike in resignations from a single team is another. Growth that changes the shape of your workforce is a third reason to look again before the next scheduled date.
It also helps to plan for the time a review takes. Ravio puts a full cycle at around 5 months from start to finish, with benchmarking data refreshed in the third quarter for a fourth quarter review and new pay landing in payslips in the first quarter of the following year. Starting late means the market might’ve moved again by the time your changes take effect.
