What is pay compression? Causes, examples & how to fix it
Published by SalaryGuide, with recruiter insight from our sister company, Search for Hire.
Pay compression happens when salary differences between employees who would normally be expected to sit at meaningfully different pay levels become unusually small.
A common example is a long-tenured employee earning almost the same as a newly hired colleague because external hiring rates moved faster than internal salaries.
Compression can also appear between managers and direct reports, or between adjacent career levels.
The problem is not that two people happen to earn similar salaries. The problem is that the relationship between pay, role scope and progression stops making sense.
A simple pay-compression example
Imagine a Senior Marketing Manager earning $105,000 after several years with the company. A newly hired Marketing Manager joins at $102,000 because the external market has moved sharply.
The $3,000 difference may be difficult to explain if the senior role carries substantially more scope and accountability.
That does not automatically mean the new hire is overpaid. The senior employee may simply have fallen behind the market.
The three most common causes
External hiring rates move faster than internal pay
When employers increase new-hire budgets to compete for talent but keep existing employees on smaller increases, internal gaps can collapse.
Promotions are priced too conservatively
If employees receive a title and responsibility increase without a meaningful salary reset, they can remain close to the level below them.
Salary structures are left unchanged for too long
Outdated ranges, freezes or inconsistent exceptions can create compression even when individual decisions looked reasonable at the time.
Where to look for compression
Tenured employees versus new hires
Compare employees doing comparable work at the same level and location.
Managers versus direct reports
A narrow gap may be legitimate in specialist teams, but it should be deliberate and explainable.
Adjacent career levels
If the upper part of one level overlaps almost completely with the next, employees may see little financial difference between progression stages.
Employees relative to range midpoints
Compa-ratio can help identify employees who are unusually low relative to the market reference used in the range.
Compa-ratio = employee salary / range midpoint
Use it as a diagnostic, not a rule that everyone should sit at 1.00.
Pay compression versus pay equity
The concepts can overlap, but they are not the same.
Pay equity asks whether compensation differences are fair and explainable across comparable employees or work.
Pay compression asks whether expected salary relationships have collapsed.
A company can have compression without a broader equity problem, and an equity problem without obvious compression.
Step 1: confirm the job structure
Before calculating gaps, make sure the employees being compared really belong in the same or adjacent groups.
Normalize titles, levels, scope and location.
Step 2: benchmark the external market
Use current salary benchmarking to check whether the issue is caused by external rates moving faster than the internal structure.
If the benchmark itself is wrong, the compression analysis will be wrong too.
Step 3: map salaries into the current ranges
For each employee, record:
- current base salary;
- level;
- range minimum;
- midpoint;
- maximum;
- relevant comparison group;
- tenure or time in level where useful.
Then identify unusual relationships rather than relying on one universal compression threshold.
Step 4: find the cause before choosing the fix
Different causes require different responses.
| Cause | Possible response |
|---|---|
| Market moved but ranges did not | Rebenchmark and update ranges |
| New-hire exceptions accumulated | Review hiring approval rules |
| Promotions were underpriced | Revisit promotion pay policy |
| Long-tenured salaries stagnated | Target market or compression adjustments |
| Job levels are poorly defined | Fix job architecture before adjusting pay |
Step 5: model remediation scenarios
Do not promise corrections before understanding the cost.
Separate employees into priority groups, such as:
- below range minimum;
- materially below comparable peers for unexplained reasons;
- compressed against new hires or lower levels;
- within structure but needing future monitoring.
This makes the budget discussion more disciplined than giving everyone the same percentage increase.
Step 6: fix the policy that created the problem
A correction is temporary if the company continues making the same decisions.
Review:
- salary-range refresh cadence;
- new-hire exception approvals;
- promotion increases;
- merit budgets;
- manager guidance;
- rules for geographic or skill premiums.
If the ranges themselves need redesign, use how to determine salary ranges.
When salary-range overlap is not compression
Healthy salary structures often have overlap between adjacent levels. A highly experienced employee at one level can legitimately earn more than someone new to the level above.
Compression is about whether the relationship still makes sense in context, not whether every salary follows a perfect ladder.
What not to do
Do not lower new-hire salaries just to restore the gap
If the market has genuinely moved, that can make hiring impossible without solving the underlying problem.
Do not use across-the-board raises as the only tool
The same percentage increase preserves many existing relationships instead of fixing them.
Do not hide the range architecture from managers
Managers need to understand how the company defines levels and progression if they are expected to explain pay decisions consistently.
A simple compression review cadence
Monitor high-risk roles whenever market rates or hiring budgets move materially, and include compression checks in the broader compensation analysis.
The goal is not to eliminate every overlap. It is to catch relationships that no longer reflect role scope, market position or progression before they become embedded.
