Analyze salary differences within a grade to identify potential compression issues
Pay compression refers to a situation where there are very small salary differences between people in the same grade regardless of their performance, experience, or tenure.
This calculator measures compression using the coefficient of variation, which indicates how dispersed salaries are within a grade. A lower percentage indicates higher compression.
To calculate grade compression, enter all salaries for employees in one grade. Add or remove rows as needed for all employees in that grade level.
Pay compression under 5% is considered severe and may lead to retention issues, especially for experienced employees who see little salary difference from new hires.
Manager and report, tenured and new hire, or any two peers you want to compare.
The tool returns the compression ratio and percentage difference between the two figures.
Flag the relationship as compressed, healthy, or inverted, and plan the adjustment before merit cycle.
Plug in any two salaries — manager vs. report, tenured vs. new hire, two peers — and get the compression ratio.
Flags the more dangerous case where the supposedly junior or newer employee is paid more than the senior — a hidden retention risk.
All computation in your browser. Sensitive comp data never leaves the page.
Comp teams use this to investigate equity complaints, audit post-merger pay structures, and run pre-merit-cycle health checks.
“After a hot hiring market in 2023, our new-hire salaries had crept past tenured staff in the same role. This calculator made the inversion impossible to ignore at the leadership table.”

“We had three managers earning less than two of their direct reports. Ran every pair through this and built the case for an off-cycle adjustment.”

Compression takes four common shapes inside an organization:
Three forces drive compression more than anything else. Hot hiring markets push new-hire salaries up faster than internal merit increases can keep tenured staff ahead. Mergers and acquisitions slam together two pay structures that were never designed to align. Minimum-wage shifts compress the bottom of the structure when the floor moves but the rest doesn’t. None of these are anyone’s fault — they’re structural — and that’s exactly why catching them requires running the numbers deliberately rather than waiting for a complaint.
Tenured employees quit when they realise new hires are matching their pay — and their replacements typically cost 15–25% more than retaining them would have. Managers lose authority and confidence when they’re paid the same as direct reports, which leaks into team dynamics. Internal moves stall because lateral pay is identical to current pay, so high-potential employees stop volunteering for stretch roles. Each of these is hard to attribute back to compression after the fact, which is why it goes uncaught for years.
The discipline that works: run this calculator across every manager-report pair quarterly, and across every same-role group during merit planning. Set explicit thresholds — flag any manager-to-report gap below 10%, any peer gap below 5%, any new-hire vs. tenured-staff gap below 10%. Then triage the flagged cases by tenure, performance, and time-since-last-adjustment. Most organizations find more compression than they expect on the first pass; the second pass starts cleaner.
Off-cycle adjustments for the compressed individual are fast but expensive and politically tricky (everyone else hears about them). Wider grade structures are slow and structural but address the root cause. Promotion-driven differentials are the cleanest fix when justified — you raise the senior person’s pay through a real title change. One-time bonuses are the least sustainable; they paper over the issue for one cycle and the compression returns. Most healthy comp programmes use a mix, weighted by urgency and how systemic the compression is.
Compression is downstream of your pay structure, your range penetration patterns, and your compa-ratio targets. If you’re finding compression repeatedly in the same role family, the root cause is upstream — either the band is too narrow, the midpoint is misaligned to market, or the merit budget is too small to keep pace with hiring inflation. Compression is the symptom; those three are the levers.
