Find the value at any percentile in your data set. Paste a list of numbers separated by commas, spaces, or new lines, pick a percentile from 0 to 100, and the tool returns the value at that rank using linear interpolation between the nearest data points. The 50th percentile is the median, the 25th and 75th are the lower and upper quartiles, and the 90th is a common cutoff for outliers or top performers. Percentiles describe position within a distribution without assuming any particular shape, which makes them robust and easy to explain. They show up in test scoring, growth charts, salary bands, and web performance metrics like p95 latency. Results update as you type.

The nth percentile is the value below which that percent of your data falls, so the 90th percentile has 90 percent of values at or below it.
It uses linear interpolation between ranked data points to find the value at the chosen percentile position.
Quartiles are the 25th, 50th and 75th percentiles, dividing the sorted data into four equal parts.
