**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%
