Percentile Calculator

Find the value at a given percentile of a dataset.

Introduction

Percentile Calculator — Find the value at a given percentile of a dataset. Enter Dataset (comma-separated), Percentile to get an instant, accurate result.

Formula

The data is sorted, then the value at rank = (p/100) × (n−1) is found by linear interpolation between the two closest data points (the same method as Excel's PERCENTILE.INC).

Step-by-step

  1. Enter the Dataset (comma-separated).
  2. Enter the Percentile.
  3. Click Calculate to see your result instantly.

Real-world example

Example: With Dataset (comma-separated) = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, Percentile = 50, the Percentile Calculator gives Percentile: 5.5.

Frequently Asked Questions

What does the 50th percentile equal?
The 50th percentile is the median of the dataset.
Are there other percentile methods?
Yes — statistical software sometimes uses slightly different interpolation conventions, so results can differ marginally between tools.
What inputs does the Percentile Calculator need?
You'll need to provide: Dataset (comma-separated), Percentile. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Percentile Calculator?
The Percentile Calculator applies the formula exactly as calculated — The data is sorted, then the value at rank = (p/100) × (n−1) is found by linear interpolation between the two closest data points (the same method as Excel's PERCENTILE.INC). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Percentile Calculator free to use?
Yes, the Percentile Calculator is completely free, requires no signup, and runs instantly in your browser.

About the Percentile Calculator

The Percentile Calculator uses a real, verifiable formula — The data is sorted, then the value at rank = (p/100) × (n−1) is found by linear interpolation between the two closest data points (the same method as Excel's PERCENTILE.INC). — so results are accurate every time, not an approximation.
