How this percentile calculator works
Enter your rank and the total number of candidates. The calculator uses Percentile = ((Total − Rank) ÷ Total) × 100. Rank 1 out of 100 is 99.00%. Rank 50 out of 100 is 50.00%. The result is shown to two decimal places.
Under this formula, the percentile is the share of the list counted as below your rank: Total − Rank people, divided by Total. Rank 1 of 500 is 99.80%. Rank 10 of 1,000 is 99.00%. Rank 250 of 1,000 is 75.00%. When Rank equals Total, the percentile is 0.00%.
Total candidates must be greater than 0. Both fields must be finite numbers. An empty box or a zero total leaves the result as “--.” A better (smaller) rank raises the percentile; rank 25 of 200 is 87.50%.
This is a rank-and-total tool of the kind often used on exam or merit lists. It is not a statistical percentile computed from a full set of scores. Check by hand: subtract rank from total, divide by total, multiply by 100.
