Percentile Calculator
Percentile calculator
Find percentile value from a numeric dataset with interpolation.
Result
7.6
Computed from n = 8 values using linear interpolation.
percentile rank
Advanced options
Flow
- Paste or type a numeric list separated by commas or spaces.
- Enter percentile from 0 to 100.
- Read interpolated percentile value and dataset-size helper text.
Example
Worked example: P90 for 2,4,4,4,5,5,7,9
- 1 Sort values and compute rank = 0.90 × (8 - 1) = 6.3
- 2 Interpolate between index 6 (7) and index 7 (9)
- 3 P90 = 7 + 0.3 × (9 - 7) = 7.6
The 90th percentile is 7.6.
How
- Paste or type a numeric list separated by commas or spaces.
- Enter percentile from 0 to 100.
- Read interpolated percentile value and dataset-size helper text.
Avoid
- Expecting nearest-rank output when interpolation mode is used.
- Including non-numeric tokens in dataset input.
- Confusing percentile value with percentile rank of a specific point.
Checks
Best fit
Percentile Calculator is built for compute percentile values from numeric datasets using interpolation. If Percentile Calculator does not match the input scope, compare the answer with a second method.
Input check
Match the entered values to this rule before copying the answer: Position = (p/100) × (n - 1) with linear interpolation between adjacent sorted values.
Sanity check
For Percentile Calculator, use the worked example as a quick benchmark: The 90th percentile is 7.6. If the percentile calculator answer is far away, check whether an input, unit, or mode changed.
Before copying
Review this common issue first: expecting nearest-rank output when interpolation mode is used.
FAQ
Does this support decimals in data?
Yes, decimal values are fully supported.
What percentile range is allowed?
Any value from 0 to 100 inclusive.
Why can percentile be between two data points?
Interpolation estimates values between sorted observations.
