What is Percentage Change?

Percentage change quantifies the increase or decrease in a quantity over a given period. To calculate the percentage change, the formula is:

Formula for Percentage Change

Percentage Change = [(New Value - Old Value) / Old Value] * 100

Worked Examples Using Percentage Change Calculator

Example 1

• Initial= 50

• Final value = 75

Percentage Change

• [(75 - 50) / 50]* 100

•  [25 / 50]* 100

•  0.5 * 100

• 50%

In this example, the value increased by 50% from the old value of 50 to the new value of 75.

Example 2, When The Change is Negative

• Old Value = 200

• New Value = 150

Percentage of change

• = [(150 - 200) / 200] * 100

• = [-50 / 200] * 100

• = -0.25 * 100

• = -25%

In this example, the value decreased by 25% from the old value of 200 to the new value of 150.

Example 3, When The  Change Remain Constant

• Old Value = 80

• New Value = 80

Percentage change

• = [(80 - 80) / 80] 100

• = [0 / 80] 10

• = 0 * 100

• = 0%

In this example, there is no change in value as the old value of 80 is the same as the new value of 80, resulting in a 0%.
