Range penetration shows how far into a pay range a salary sits, from the minimum to the maximum. It answers a question compa-ratio cannot, because it accounts for how wide the range actually is. Every number on this page is calculated in your browser and never leaves your device.

Penetration drifts as people progress and ranges get rebuilt, so the useful view is several cycles side by side. The HRAnalyst™ Workbook is a printable tracker for every calculator on this site, with the formula, the recommended cadence and space for four quarters.

Quartile targets are a common practice convention described in compensation practitioner literature, including WorldatWork materials. They are not a standard, and organizations set their own targets.

Compares a salary to the midpoint, which is the market rate. That makes it the cleaner lens for comparing pay across different jobs and grades, and for pay equity review, where the question is whether people are paid fairly against the market for the work.
Compares a salary to the full width of the range. That makes it the better lens for understanding how much room an employee has before reaching the ceiling, and for career progression conversations.
A wide range can make a below market salary look comfortable on penetration alone. A narrow range can make a fair salary look stuck. Neither figure is wrong. They answer different questions and you generally need both.
A salary exactly at the midpoint always produces a compa-ratio of 1.00, but its range penetration equals 50 percent only when the range is symmetrical around the midpoint. Ranges built from a midpoint and a percentage spread usually are not.
The minimum and the maximum have to be anchored to market data from outside your own payroll, or you are measuring position against a range you invented.
What It Pays™ has government verified wage data by role and state, so you can test a single range against the market. Organizations that need to anchor every range rather than one at a time can do that through an employer account.

Range penetration = (salary - range minimum) / (range maximum - range minimum)
Expressed as a percent
A salary below the range minimum produces a negative penetration and a salary above the maximum produces a figure over 100 percent. Both are real situations, both are worth surfacing, and this calculator shows them rather than suppressing the result.
It is only when the range is built symmetrically. Ranges constructed from a midpoint and a percentage spread place the midpoint above the arithmetic center, so the midpoint typically lands somewhat above 50 percent penetration.
Ranges widen at senior levels. Fourth quartile in a wide executive range and fourth quartile in a narrow entry range describe very different situations.
Someone deep in their range is often exactly where a long tenured expert should be. The question it raises is career path, not overpayment.
Practitioner guidance repeatedly warns that employees shown a penetration percentage often conclude they should be at 100 percent if they are performing well. The top of a range is the ceiling for the job, not a reward for tenure. Share relative positioning and what it means, not a bare number.
