Percentile Calculator
Paste a data set to find the value at a chosen percentile, or the percentile rank of any value. Percentiles use linear interpolation, the same method as Excel PERCENTILE.INC and NumPy.
How to calculate a percentile
- Enter your numbers separated by commas, spaces or new lines.
- Set a percentile from 0 to 100 to read the value at that rank.
- Enter a value to see its percentile rank within the data.
Examples
Median of 1 to 10
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 at the 50th percentile
Value at 50th percentile = 5.5
Frequently asked questions
What is a percentile?
A percentile is the value below which a given percentage of the data falls. The 90th percentile is the value that 90 percent of the data is at or below.
What is a percentile rank?
The percentile rank of a value is the percentage of the data that is at or below it. A rank of 75 means the value is at or above three quarters of the data.
Which percentile method does this use?
Linear interpolation between closest ranks, matching Excel PERCENTILE.INC and NumPy's default. The 50th percentile equals the median. A nearest-rank option is also available.
Is the 50th percentile the same as the median?
Yes. With linear interpolation the 50th percentile is exactly the median, the middle value of the sorted data.
Do I need to sort my data first?
No. The calculator sorts your values automatically before computing any percentile.
