Compa-Ratio & Range Penetration Calculator
Compa-ratio (comparative ratio) measures how an individual employee's pay compares to the midpoint of their salary range. Range penetration shows where pay falls between the minimum and maximum. Together, these metrics are the foundation of compensation administration — used for merit planning, promotion decisions, and pay equity audits.

Position in Salary Range
Compa-ratio and range penetration are diagnostic tools, not goals. Appropriate position depends on tenure, performance, and market conditions.
Interpreting Compa-Ratio
| Compa-Ratio | Meaning | Typical Action |
|---|---|---|
| Below 0.85 | Significantly below market | Immediate market adjustment |
| 0.85 – 0.95 | Below midpoint | Prioritize for merit increase |
| 0.95 – 1.05 | At market | Standard merit increase |
| 1.05 – 1.15 | Above midpoint | Moderate merit; promotion readiness |
| Above 1.15 | Near or above max | Lump-sum bonus; evaluate for promotion |
Frequently Asked Questions
What if an employee exceeds the range maximum?
This is called being “red-circled.” Options include freezing base pay until the range catches up, providing lump-sum bonuses, promoting the employee to a higher grade, or restructuring the range.
