How do I calculate percentage change?

Subtract the old value from the new value, divide by the old value, then multiply by 100. Formula: ((New - Old) / Old) × 100. Positive result = increase, negative = decrease.

What is the difference between percentage change and percentage difference?

Percentage change shows change from a starting point (directional: +/-). Percentage difference compares two values without direction (always positive). Use change when tracking growth/decline over time.

Can percentage change be negative?

Yes, negative percentage change indicates a decrease. For example, going from 100 to 80 is a -20% change, meaning a 20% decrease.
