What inputs to check

Enter rank and cohort size, let the calculator convert your position into a cohort percentile, then check the result label and limits. After that, learn how to interpret the figure.
Reading your percentile
Your percentile shows where you sit compared with the cohort—higher means closer to the top. Use the tool's labels to judge precision and relevance. Next, see what affects accuracy.
Limits and accuracy
The estimate depends only on the values you enter and the calculator's stated rules; it can't verify dates, handle ties, or reflect different scoring systems. Check FAQs for edge cases. Ready for details?
