Pay Compression Checker

Pay compression happens when the pay gap between levels — or between new and tenured staff — becomes too small. This checks the differential between two salaries and flags a narrow or inverted gap.

Differential between levels

Enter the pay of a lower role (e.g. a senior employee or subordinate) and a higher role (e.g. their new hire or manager).

Indicative only. For pay decisions that matter, our consultants provide the full methodology and market data.

How to check for pay compression

  1. 1Enter the two salaries you want to compare (e.g. manager vs. subordinate, or tenured vs. new hire).
  2. 2The tool calculates the percentage differential between them.
  3. 3Review the flag: a narrow or negative (inverted) differential indicates pay compression that may need attention.

Frequently Asked Questions

What is pay compression?

Pay compression happens when the pay gap between job levels — or between long-serving staff and new hires — shrinks to the point where it no longer reflects the difference in responsibility or experience.

What causes pay compression?

Common causes include rising market rates for new hires, minimum-wage increases, long gaps between internal pay reviews, and promotions made without an adequate pay adjustment.

What is pay inversion?

Pay inversion is the most severe form of compression, where a more junior or newer employee earns more than a more senior or longer-tenured one.
