Frequently Asked Questions

How do I calculate percentage change?

Percentage change is calculated as ((New Value - Original Value) / |Original Value|) × 100. A positive result indicates an increase, while a negative result indicates a decrease.

What is the difference between percentage change and percentage difference?

Percentage change measures the change relative to the original value and has a direction (increase or decrease). Percentage difference measures the difference between two values relative to their average and has no direction.

What is the multiplier?

The multiplier is the ratio of the new value to the original value. A multiplier of 1.5 means the new value is 1.5 times the original, representing a 50% increase.
