What is percentage change?

Percentage change measures how much a value has changed relative to its original amount, expressed as a percentage. It shows the direction (increase or decrease) and the magnitude of the change.

How is percentage change different from percentage difference?

Percentage change compares a new value to an old baseline (time-based). Percentage difference compares two values of the same type with no defined starting point, using their average as the base.

Can I get a negative percentage change?

Yes. If the new value is less than the old value, the result will be negative, indicating a percentage decrease.
