What is Percentage Increase?

Percentage increase serves as a means to express a change in a value relative to its original magnitude. It provides a standardized metric, facilitating straightforward comparisons and enhancing comprehension of alterations, whether they pertain to prices, incomes, or any other metrics.

Start by taking the difference between the new number (the final value) and the old number (the initial value). Then, divide this result by the old number. Lastly, multiply the quotient by 100 to represent the increase as a percentage.
For instance, let's say the old number is 50, and the new number is 70:

  1. Percentage Increase = [(70 - 50) / 50] * 100
  2. Percentage Increase = (20 / 50) * 100
  3. Percentage Increase = 40%
  4. In this example, the percentage increase from 50 to 70 is 40%.
