Compa-Ratio vs. Range Penetration

Two common compensation measures, what each one answers, and when they can mislead.

What each measure is for

Compa-ratio is useful when the question is how pay compares to the midpoint. Range penetration is useful when the question is where pay sits inside the full range.

Why they are easy to mix up

Both measures describe position in range language, but they are not interchangeable. They answer different questions and can tell different stories about the same employee.

What to check before using either one

• range design and midpoint integrity
• job match quality
• whether the range is current
• the employee’s context relative to peers

Practical takeaway

Start with the decision context, then choose the measure that answers it.
