Calculate salary range penetration (position in range) and compa-ratio from a salary and its pay range, or find the salary for a target range position.

Use gross pay on the same pay period and full-time basis for every amount.

Reference midpoint and comparison options
Blank uses the arithmetic center. A published reference need not be the band’s 50% position.

Salary Range Penetration Formula

The following equation is used to calculate the Salary Range Penetration.

SRP = (S - Min) / (Max - Min) × 100%
  • Where SRP is the Salary Range Penetration (%)
  • S is the individual’s salary ($)
  • Min is the minimum salary in the range ($)
  • Max is the maximum salary in the range ($)

To calculate salary range penetration, subtract the range minimum from the salary, divide by the difference between the maximum and minimum, and multiply by 100. Use the same currency, pay period and full-time-equivalent basis for every amount. The maximum must exceed the minimum; positions below 0% or above 100% are possible.

What is a Salary Range Penetration?

Definition:

Salary range penetration describes the linear position of a salary relative to a defined pay range. It is not a percentile of employee pay and does not measure performance, market competitiveness or fairness. Compa-ratio is a separate comparison: salary divided by the selected reference midpoint. The arithmetic center is 50% penetration, but a different published compa-ratio reference need not occupy that position.

How to Calculate Salary Range Penetration?

Example Problem:

The following example outlines the steps and information needed to calculate the Salary Range Penetration.

First, determine the individual’s salary. In this example, the salary is $80,000.

Next, determine the minimum and maximum of the salary range. Let’s say the minimum is $60,000 and the maximum is $100,000.

Finally, calculate the salary range penetration using the formula above:

SRP = ( S – Min ) / ( Max – Min ) * 100%

SRP = ( $80,000 – $60,000 ) / ( $100,000 – $60,000 ) * 100%

SRP = $20,000 / $40,000 * 100% = 50%

FAQ

Why is salary range penetration important?

Salary range penetration describes where a salary lies relative to the organization’s chosen range. It can inform a compensation discussion, but the number alone does not establish external competitiveness, pay equity or fair treatment.

Can salary range penetration differ across different industries or roles?

Yes. Range widths and reference midpoints depend on the organization’s pay structure and the role being compared. Compare compatible ranges and pay periods; penetration does not predict how quickly an employee will progress.

How often should salary range penetrations be reviewed?

Recalculate when salary, range limits, the reference midpoint or the comparison basis changes. Review timing follows the organization’s compensation policy; a penetration calculation does not determine the appropriate review schedule.
