How the percentile rank calculator works
Estimate percentile rank from the number of scores below and equal to a score.
With 70 scores below and 2 equal scores among 100, the midpoint percentile rank is 71.
Assumptions and limitations
Percentile conventions differ. This tool uses half of tied scores, so an institution using another convention may report a different value.

Frequently asked questions
Does the percentile rank calculator send my data anywhere?
No. It runs client-side in your browser and makes no network requests.
Why is the result blank or shown as a dash?
One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.
Can I use decimal values?
Yes, where decimals are meaningful. Counts that represent whole items may require integers.
