What Is a Percentage?

A percentage represents a part of a whole out of 100. It helps compare values, express ratios, and analyze data in mathematics, finance, statistics, and everyday calculations. Formula:

Percentage (%)=(PartWhole)×100 \text{Percentage (\%)} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100

Percentage vs Percentage Points

A percentage shows a value relative to 100, while percentage points measure the direct difference between two percentages. For example, an increase from 10% to 12% equals 2 percentage points.

Percentage vs Percentile

A percentage represents a fraction of 100, while a percentile shows a ranking within a group. For example, the 90th percentile means a value is higher than 90% of the data set.
