Salary Benchmark Percentile Calculator

Enter the market 25th, 50th and 75th percentile pay to see where your salary lands.

How it is calculated

The tool places your salary on a straight line between the three market points you supply. Between p25 and p50, percentile = 25 + (salary − p25) ÷ (p50 − p25) × 25; between p50 and p75, 50 + (salary − p50) ÷ (p75 − p50) × 25. Outside that range the same slope is extended, and the result is held between 1 and 99. The compa-ratio is salary ÷ p50 × 100 shown as a percent, so 100% means exactly the median. The gap to the median is p50 − salary (negative when you earn more than the median), and the gap to the top is p75 − salary, never below zero. The three market values must rise (p25 < p50 < p75). Percentile values are estimates, not survey data.

Worked example

The market data for a role shows p25 = 72,000, p50 = 88,000 and p75 = 104,000, and your salary is 84,000. That is between p25 and p50: 25 + (84,000 − 72,000) ÷ (88,000 − 72,000) × 25 = 25 + 18.75 = 43.75%. Compa-ratio: 84,000 ÷ 88,000 × 100 = 95.45%. Gap to the median: 88,000 − 84,000 = $4,000.00. Gap to the top of the range (p75): 104,000 − 84,000 = $20,000.00. You are slightly below the middle of the market.

Common mistakes

  • Mixing pay definitions: a base salary against benchmark data that includes bonus and equity, or the reverse. Use benchmarks and your pay on the same basis.
  • Entering the percentiles in the wrong order or mixing the 50th with the average. The median and the mean differ when a few high salaries pull the average up.
  • Using benchmarks for a different level, location or year than your own role. A 5% pay gap can be a normal difference between two cities.
  • Reading the percentile as exact. It is interpolated between three points, so it is a rough position, and far from the three points the figure is only an extension.
  • Reading a compa-ratio of 109% as overpaid. It only says you are above the median, and a high result can reflect experience or scope.

About this calculator

Salary benchmarking compares an individual's pay against market data reported at specific percentiles — typically the 25th, 50th (median) and 75th percentile for a role, level and location. Where your salary falls between those points shows your percentile rank (estimated by straight-line interpolation between the three points, and kept between 1 and 99), and dividing your actual pay by the market median gives the compa-ratio (shown here as a percentage: 100% means you're paid exactly at market median; below 90% or above 110% is generally flagged for review).

HR and compensation teams use percentile and compa-ratio together when setting pay bands, deciding merit increases, and auditing for pay equity across a workforce, since a raw salary number means little without market context — $90,000 could be well above or well below market depending on the role and location. Employees negotiating an offer or a raise use the same benchmarks to argue their position with concrete numbers rather than a general sense of being under- or overpaid.
