To calculate the percentage increase between two numbers, we use the formula, Percentage Increase = [ (Final Value - Initial Value)/Initial Value] × 100. For example, the height of an apple tree increases from 15 ft to 18 ft in a year.

Calculating a percentage means dividing the number by the whole and multiplying it by 100. Thus, it can be said that percentage means a part per hundred. The symbol % represents percentage.

Percentage is nothing but a number which is represented as the ratio and expressed as the fraction of 100. After the number, it has % symbol. The formula to calculate percentage is of a number is follows Number % = (Number / Total Value) x 100.

The word “percent” is a unit of measure and should always be preceded by an amount. Although similar, the word “percentage” should never be preceded by an amount. Additionally, “percent” always introduces the whole denominator, whereas “percentage” can introduce either the whole or part denominator.
