Summary
This percentile calculator works in two modes: given a value, it computes its percentile rank within your dataset; given a percentile (0–100), it returns the corresponding value using standard linear interpolation (the same method used by NumPy, Excel PERCENTILE.INC, and most statistical software). Simply paste or type your comma-separated numbers, then switch between modes.
How it works
- Enter your dataset as comma-separated numbers in the input box.
- Choose a mode: "Find Rank" to get the percentile of a specific value, or "Find Value" to get the value at a given percentile.
- Enter the value or percentile you want to look up.
- Click Calculate — results appear instantly with a sorted data table.
- Switch modes at any time without re-entering your dataset.
Use cases
- Determine where a test score falls relative to a class.
- Find the 90th-percentile response time in a performance dataset.
- Analyze salary distributions or pricing data.
- Check if a measurement is in a normal range (e.g., height, weight).
- Compute quartiles (25th, 50th, 75th percentile) for box plots.
- Identify outliers at the extremes of a dataset.
