Percentile Calculator

90th

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. Everything runs locally in your browser, so your data set is never uploaded anywhere.
