What is Percentage Change?

Percent change refers to the relative difference or percentage difference between two values. It is commonly used to measure and express the rate of change or the extent of a change in a particular quantity over time.

Percent Change = ((New Value – Old Value) / Old Value) * 100
In this formula:

  • Old Value represents the initial or starting value.
  • New Value represents the final or updated value.

= (($65 – $50) / $50) * 100
= ($15 / $50) * 100
= 0.3 * 100
= 30%

Therefore, in this example, the percent change is Increase 30%.
