Salary range penetration: where pay sits inside the band

Salary range penetration is where a person's pay sits within their band from bottom to top: pay minus range minimum, divided by range maximum minus minimum, as a percentage. It answers a simple question the compa-ratio does not: how much of the band has this person already used?

How it is calculated

Subtract the band minimum from the salary, divide by the full width of the band, multiply by 100. In a band running SAR 30,000 to SAR 50,000 a month, an employee on SAR 35,000 has penetration of 25%. They are a quarter of the way through the range, with three quarters of headroom before the maximum.

What it is used for

Penetration is the progression measure. It shows how much room remains for increases without breaching the band, which makes it central to salary-review planning: an employee at 90% penetration cannot receive a normal increase for long before hitting the ceiling, and that conversation is better had before the review cycle than during it. Compared across a team, penetration also exposes clustering, such as a whole function packed into the top third of its band with nowhere to go.

What this means for a comp lead

Track penetration alongside compa-ratio, not instead of it. The ratio reads position against the market anchor; penetration reads remaining runway inside the structure. An employee can look healthy on one and be stuck on the other, and pay decisions made on a single measure tend to find that out later.
