About the 40th Percentile Calculator
The 40th percentile is the value below which about 40% of the numbers in a data set fall. Enter your values and this calculator finds it by linear interpolation between the two closest ranks, the same method as Excel's PERCENTILE.INC.
For the starting values (12, 15, 15, 18, 22, 27, 31), the 40th percentile is 16.2.

Things to keep in mind
- You do not need to sort the values; the calculator does it.
- A percentile value is a number from your data's scale; a percentile rank tells you where a given value sits. They are different questions.
- Different software uses slightly different percentile methods, so small differences from other tools are normal.
