The Formula

Percentile rank = (L/N) × 100

The percentile formula uses the mathematical relationship: Percentile rank = (L/N) × 100. Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the percentile calculation.
  2. 2Substitute your known values into the formula: Percentile rank = (L/N) × 100.
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
