Percentile Calculator

How It Works

Input a list of numbers (comma-separated or space-separated) as the dataset. Choose to either find the percentile rank of a specific data point or the value at a given percentile (0-100). The calculator will compute the result using interpolation if needed. Click “Calculate” to see the result. Share or embed the calculator using the provided buttons.

About Percentile Calculator

The Percentile Calculator determines the percentile rank of a data point within a dataset or finds the value corresponding to a given percentile rank, using interpolation for accuracy.

How to Use

Enter a list of numbers, separated by commas or spaces (e.g., 1, 2, 3 or 1 2 3).
Select the mode: “Percentile of a Value” to find the percentile rank of a data point, or “Value at Percentile” to find the value at a given percentile (0-100).
Enter the value or percentile as required based on the selected mode.
Click “Calculate” to compute the result. The page will scroll to the result.
Click “Clear” to reset the inputs and results.

The result and calculation steps will be displayed.

Formula

For Percentile of a Value:

P = (i / n) × 100

For Value at Percentile (interpolation):

Value = x[(P/100) × (n-1)] + (P/100 – k) × (x[k+1] – x[k])

Where:

P = percentile rank (%)
i = rank of the value (position in sorted list)
n = number of data points
k = floor((P/100) × (n-1))
x[k] = value at position k
x[k+1] = value at position k+1

Important Notes

Enter at least two numbers in the dataset.
For “Value at Percentile,” the percentile must be between 0 and 100.
Numbers can be integers or decimals, separated by commas or spaces.
The keypad’s Clear button clears the active input field.
