Calculated in this browser. Nothing is sent anywhere.

Type-7 linear interpolation (Excel's PERCENTILE.INC / R's default). Rank counts values strictly below plus half the ties.

How to use

  1. Paste numbers (comma, space, or newline separated).
  2. Enter a percentile or a value.
  3. Read the interpolated answer.

What it supports

Nearest-rank-free linear interpolation (the common 'type 7' method used by Excel/NumPy). Up to 200,000 values, min/max/median reported alongside. Percentile of a value uses the inverse: rank = (values below + half of equal) ÷ n.
