Frequently asked questions
What if my value isn't in the dataset?
You can still compute its rank relative to where it would fall among the existing values.
How is this different from a percentile?
A percentile finds the value at a given rank; percentile rank finds the rank of a given value — they're inverses.
What do I need to enter into the Percentile Rank Calculator?
Just 2 values: dataset (comma-separated), value to rank. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Percentile Rank Calculator work out the answer?
Percentile rank is the percentage of values in the dataset that are less than or equal to the given value. It applies the formula PR = (count below + 0.5*count equal) / n * 100 and shows the working so you can check each step by hand.
Is the Percentile Rank Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
