An employee’s salary number does not tell HR whether that person is paid near the bottom, middle or top of the organization’s range for the role. Compa-ratio adds that context by comparing an employee’s salary with the midpoint of the relevant salary range.
How do you calculate compa-ratio?
Suppose an organization has a salary range of $60,000 to $90,000 for a role.
- Calculate the midpoint: ($60,000 + $90,000) ÷ 2 = $75,000.
- Identify the employee’s base salary: $72,000.
- Divide salary by midpoint: $72,000 ÷ $75,000 = 0.96.
- Convert to a percentage: 0.96 × 100 = 96%.
The employee’s compa-ratio is 96%.
What does a compa-ratio tell HR?
It gives a consistent way to compare salary position across employees in different pay ranges. HR can use it to:
- Identify employees who sit materially below or above the midpoint of their range.
- Review whether pay progression is working as intended.
- Find groups that may need a closer market or equity review.
- Add context to merit-increase decisions.
- Monitor the effect of salary changes on range position.
A compa-ratio is a diagnostic signal, not a verdict. A person below midpoint may be new to the role or still developing the required skills. Someone above midpoint may have extensive experience or scarce expertise. The number does not reveal the reason by itself.
Is a 90% or 100% compa-ratio good?
There is no universal “good” compa-ratio. Some organizations use internal guide ranges, but the appropriate reference depends on the pay philosophy, job family, employee proficiency, market data and range design. Do not label every employee below an arbitrary threshold as underpaid or every employee above it as overpaid.
Use compa-ratio as a prompt for a structured review. Compare employees in similar roles and levels, examine relevant experience and performance, and check whether the underlying salary range is current and credible.
Compa-ratio vs. range penetration: What is the difference?
The measures answer different questions:
| Measure | What it compares | Typical formula |
|---|---|---|
| Compa-ratio | Salary against range midpoint | Salary ÷ midpoint × 100 |
| Range penetration | Salary’s position between range minimum and maximum | (Salary − minimum) ÷ (maximum − minimum) × 100 |
For a range of $60,000–$90,000 and a salary of $72,000, compa-ratio is 96%. Range penetration is 40%. A compa-ratio of 100% corresponds to 50% range penetration when the midpoint is exactly halfway between the minimum and maximum.
How can HR use compa-ratio in a merit cycle?
Compa-ratio can be one input in a merit matrix. For example, an organization may decide that a strong performer below the midpoint should receive a different increase opportunity from a strong performer already near the range maximum. That policy should be designed, tested and communicated before the cycle begins.
It should not be the only input. Consider performance evidence, role scope, market movement, pay equity, tenure where relevant, prior adjustments and the available budget. A simple ratio cannot replace a compensation philosophy.
Common compa-ratio mistakes
- Comparing an employee with the wrong job range.
- Mixing annual, monthly and hourly salary figures without normalization.
- Using total compensation for one employee and base pay for another.
- Treating the midpoint as a guaranteed target salary.
- Using stale or poorly matched market data to set range midpoints.
- Treating a single ratio as proof of a pay-equity problem.
Frequently asked questions
Can compa-ratio be more than 100%?
Yes. It means the employee’s base salary is above the midpoint of the applicable range. It does not automatically mean the employee is overpaid.
Does a 100% compa-ratio mean an employee is paid fairly?
Not on its own. It means the salary equals the range midpoint. Fairness also depends on role comparability, the quality of the range, relevant job-related factors and consistent decision-making.
Should compa-ratio determine salary increases?
It can inform the decision, especially when combined with performance and budget rules, but it should not be the sole determinant.
Who should calculate compa-ratio?
Compensation or HR teams typically define the ranges and calculation method. Finance can use the results in budget planning, while managers may receive guidance on how to discuss pay position.
Put employee salary data into context
MeritCyc helps compensation teams look beyond a single increase percentage by connecting increment criteria, budget scenarios and employee-level decision records. Use compa-ratio as one carefully defined input in a broader process, not as a shortcut to judgment.
