How the percentile rank calculator works

Estimate percentile rank from the number of scores below and equal to a score.

Percentile rank = (scores below + 0.5 × equal scores) ÷ total scores × 100.

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.

Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.

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.
