Percentage Difference = [(New Value - Original Value) / Original Value] × 100

This formula gives you the percentage change from the original value to the new value. A positive result indicates an increase, while a negative result indicates a decrease.

Note: The original value should not be zero to avoid division by zero errors.

Worked Example

Let's calculate the percentage difference between 13.5 and 15 using our formula:

Percentage Difference = [(15 - 13.5) / 13.5] × 100

= [1.5 / 13.5] × 100

= 0.1111 × 100

= 11.11%

This means that 15 is 11.11% higher than 13.5. The calculator will display this result along with a chart showing the relationship between the two values.
