# Percentage vs. Percentile — What's the Difference?

Edited by Tayyaba Rehman — By Fiza Rafique — Updated on October 10, 2023
"Percentage" refers to a portion of 100, while "Percentile" indicates a data point's position relative to others in a dataset, often in terms of percentage rank.

## Key Differences

"Percentage" and "Percentile," while connected through their association with 100-part divisions, articulate different mathematical and statistical concepts. "Percentage" represents a fraction or a ratio expressed out of 100, used widely from mathematics to daily life, illustrating quantities proportionally related to a whole. Conversely, "Percentile" situates itself primarily within the realm of statistics, delineating a specific point’s position relative to other data points in a distribution, providing a comparative understanding of where a particular value stands amidst a dataset.
In elementary mathematics or daily commerce, "Percentage" is a familiar term, implying a straightforward calculation where a part is evaluated as a fraction of 100. This part-to-whole relationship is pervasive in various scenarios, such as calculating discounts, determining profit margins, or evaluating changes in quantities. "Percentile," meanwhile, doesn’t find itself utilized in elementary calculations or daily shopping, instead it elucidates where a particular data point ranks within a larger distribution, thereby furnishing a relative standpoint rather than a direct part-to-whole relationship.
In financial analyses, "Percentage" can illustrate various financial metrics such as interest rates, profitability ratios, or financial growth, becoming a pivotal concept in comprehending financial health and trends. Alternatively, "Percentile" could be invoked to compare a specific data point, such as a company's profit margin, with a broader industry standard or against a wider set of companies, thereby providing a relative comparison that offers insights into the company's performance vis-à-vis its peers or industry norms.
Education often uses "Percentage" to reflect scores or performance, presenting a clear-cut, absolute measurement of achievement. For instance, a test score is commonly presented as a percentage, directly linking the obtained marks to the total marks. "Percentile," however, provides a comparative metric in test scores, delineating a student's performance relative to other test-takers, thereby offering not an absolute measure of performance, but a relative one, assisting in understanding where a student stands amidst peers.
In healthcare, "Percentage" might quantify health metrics or measurements, such as the percentage of patients responding to a particular treatment, thereby providing a straightforward, proportionate measure relating to a larger whole. "Percentile," in contrast, may articulate a patient’s health metric, such as a baby's weight, in relation to a broader population, offering a comparative perspective that assists in understanding the patient's health metric in a broader context, potentially aiding in deriving meaningful insights regarding anomalies or trends.

#### Percentage

In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used.

#### Percentile

Percentile illustrates a data point's position within a distribution, not the value itself.

#### Percentile

In statistics, a percentile (or a centile) is a score below which a given percentage of scores in its frequency distribution falls (exclusive definition) or a score at or below which a given percentage falls (inclusive definition). For example, the 50th percentile (the median) is the score below which (exclusive) or at or below which (inclusive) 50% of the scores in the distribution may be found.

## Common Curiosities

#### Does a higher Percentile always indicate a higher absolute value?

Not necessarily, it indicates a higher ranking but not necessarily a higher absolute value.

#### Is Percentile an absolute measure of value?

No, percentile indicates the relative standing of a data point within a distribution.

#### Is Percentage used in comparative statistical analyses?

Not commonly, percentages give a direct part-to-whole measure, not a comparative measure like percentiles.

#### Can Percentile be used to evaluate financial growth?

While possible, percentiles are typically used for ranking, not evaluating absolute growth like percentages.

#### Can Percentage indicate a data point’s position within a distribution?

No, percentage doesn’t offer data point positioning within a distribution; that’s a function of percentile.

#### Does Percentage always relate to 100?

Yes, percentage represents a part of a whole, where the whole is considered 100.

#### How does Percentile relate to Percentage?

Percentile is expressed as a percentage but indicates a ranking within a dataset instead of a part-to-whole ratio.

#### Is Percentile relevant in day-to-day shopping scenarios?

Rarely, as percentiles communicate comparative ranking in distributions, not straightforward part-to-whole ratios.

#### Is Percentage relevant in statistical analyses?

Percentage can be used in statistics but doesn’t offer the comparative insights of percentiles.

#### Can Percentage be used to compare two different quantities?

Yes, percentages can indicate proportions and compare different quantities proportionally.

#### Is it valid to compare Percentiles across different datasets?

Care should be taken as it may not present an accurate comparison due to differing data contexts.

#### Can Percentage be over 100%?

Yes, percentages can exceed 100% when representing growth or change exceeding the original amount.
