What is a percentile in compensation?

A percentile is a statistical measure that indicates a value's position within a ranked dataset. In compensation, percentiles are used to describe where a specific pay rate sits relative to the full distribution of pay data collected from a market data source.

When a compensation survey reports that the P50 base salary for a Senior Software Engineer is $145,000, it means that 50 percent of the organizations in the survey pay less than $145,000 for that role and 50 percent pay more. The P75 for the same role might be $168,000, meaning 75 percent of organizations pay less than that amount and 25 percentpay more.

Percentiles are not averages. A simple average can be skewed by outliers at either end of the distribution. Percentiles are more robust because they reflect actual positions in the data, making them a more reliable and widely used reference point for compensation decisions.

The most commonly used percentiles in compensation

Most market pricing work focuses on three percentiles:

• P25 (25th percentile): the lower quartile. A quarter of organizations pay below this level and three quarters pay above. P25 is sometimes used as the minimum of a pay range or as a reference for entry-level positioning within a role.

• P50 (50th percentile, also called the median): the midpoint of the market. Half of organizations pay below this level and half pay above. P50 is the most commonly used reference point for setting pay targets and is the default market reference point for most organizations.

• P75 (75th percentile): the upper quartile. Three quarters of organizations pay below this level and a quarter pay above. P75 is used by organizations that choose to position pay above the median, typically to compete more aggressively for talent.

Some organizations also reference P90 or higher for specific roles where the talent market is extremely competitive, such as senior engineering or executive positions. The right percentile target depends on the organization's compensation philosophy and talent strategy.

How percentiles are used in market pricing

Percentiles serve as the primary building blocks of the market pricing process. Once a benchmark job has been matched and a market cut has been selected, the compensation team extracts percentile values from the data source for that job and market. These values are then used to:

• Establish the market reference point (MRP): the target percentile becomes the anchor pay value for that role. An organization targeting P50 sets its MRP at the P50 value from the market data.

• Build pay ranges: the minimum, midpoint, and maximum of a pay range are typically derived from percentile values. A common approach sets the range midpoint at P50 and builds the spread around it.

• Assess pay competitiveness: benchmarking compares an employee's actual pay to the target percentile to determine how competitive their pay is relative to the market.

• Communicate pay positioning: saying an employee is paid at the 65th percentile communicates clearly where their pay sits in the market distribution, which is more meaningful and defensible than a simple dollar comparison.

Percentile vs. average in compensation data

Many compensation professionals prefer percentiles over averages when working with market data, and for good reason. Averages are sensitive to extreme values. A small number of organizations paying very high salaries for a role can pull the average well above what most organizations actually pay, making it a misleading reference point.

Percentiles are not affected by outliers in the same way. The P50 reflects the actual midpoint of the distribution regardless of how extreme the values at the top or bottom are. This makes percentile-based market data more stable, more representative, and easier to defend in compensation conversations.

That said, averages are not useless. They can surface information about the overall level of pay in a market and are sometimes reported alongside percentiles in survey data. Most experienced compensation professionals look at both but anchor their decisions to percentiles.

Choosing the right target percentile

There is no universally correct percentile to target. The right choice depends on several factors:

• Compensation philosophy: an organization that explicitly positions itself as a top-of-market employer typically targets P75 or higher. An organization focused on cost management may target P50 or below.

• Talent market dynamics: roles in highly competitive talent markets, where supply is limited and demand is high,may warrant higher percentile targets than roles where talent is more readily available.

• Role criticality: some organizations differentiate their percentile targets by role type, targeting higher percentiles for roles that are most critical to the business and lower percentiles for roles where market competition is less intense.

• Geography: percentile targets may also vary by location, reflecting the different cost and competitiveness of labor markets in different cities or regions.

The most important principle is consistency. Defining a clear percentile target and applying it systematically is more valuable than trying to optimize the target for every individual role. Inconsistency in percentile targeting is a common source of pay inequity and difficult-to-explain compensation decisions.

What does percentile mean in compensation?

In compensation, a percentile indicates where a specific pay rate falls within a distribution of market data. The 50th percentile (P50) means half of surveyed organizations pay less and half pay more for that role. Percentiles are used in market pricing to define pay targets, build pay ranges, and assess how competitive an organization's pay is relative to the market.

What is the difference between P25, P50, and P75 in salary data?

P25 is the lower quartile, 25 percent of organizations pay less than this amount. P50 is the median, half pay less and half pay more. P75 is the upper quartile, 75 percent of organizations pay less than this amount. Most organizations use P50 as their primary pay target, with P75 used by those positioning pay above the market median.

Is it better to use percentiles or averages for compensation benchmarking?

Percentiles are generally preferred over averages in compensation work because they are not distorted by outliers. A small number of organizations paying unusually high salaries can skew an average well above what most organizations actually pay, making it a less reliable reference point. Percentiles reflect actual positions in the distribution and are more stable and defensible as benchmarks.

What percentile should we target for compensation?

The right target depends on your compensation philosophy, talent strategy, and the specific roles you are pricing. Most organizations target P50 as their baseline, which aims to pay at the market median. Organizations competing aggressively for talent in tight labor markets often target P75 or higher for critical roles. The most important principle is to define a consistent target and apply it systematically.

What does it mean to be at the 75th percentile for salary?

Being paid at the 75th percentile means your pay is higher than 75 percent of the market for that role and level. An organization that targets P75 is positioning pay above most competitors, which typically helps with attracting and retaining talent but comes at a higher cost per employee than targeting P50.
