FAQ

What is the difference between percentage change and percentage difference?

Percentage change measures the change from an original value to a new value (directional — can be positive or negative). Percentage difference measures the relative difference between two values with no implied direction, using their average as the reference point.

How do I calculate a percentage increase?

Use the % Change mode. Enter the original value as "Original" and the new higher value as "New Value". A positive result indicates a percentage increase.
