Examples

Example: 1

Old Value: $500 New Value: $600

Percentage Difference Calculation:

Percentage Difference = |(New Value – Old Value) / Old Value| * 100

Percentage Difference = |($600 – $500) / $500| * 100

Percentage Difference = |$100 / $500| * 100

Percentage Difference = |0.2| * 100

Percentage Difference = 20%

In this example, the percentage difference between the old value of $500 and the new value of $600 is 20%.

Example: 2

Old Value: 150 New Value: 120

Percentage Difference Calculation:

Percentage Difference = |(New Value – Old Value) / Old Value| * 100

Percentage Difference = |(120 – 150) / 150| * 100

Percentage Difference = |-30 / 150| * 100

Percentage Difference = |-0.2| * 100

Percentage Difference = 20%

In this example, the percentage difference between the old value of 150 and the new value of 120 is also 20%
