Definition--Ratios, Proportions, and Percents Concepts--Percent Increase | Percent IncreaseTopicRatios, Proportions, and Percents DefinitionPercent increase measures the growth in value expressed as a percentage of the original value. DescriptionPercent increase is used to quantify the growth in value over time, expressed as a percentage of the original value. It is commonly used in finance, economics, and everyday scenarios such as salary increases and population growth. For example, if the price of a stock rises from \$50 to \$75, the percent increase is calculated as (75 − 50)/50 × 100 = 50% |
