How is percentage change calculated?

The formula is: ((Final Value - Initial Value) / Initial Value) × 100. The result is expressed as a percentage.

What if the result is negative?

A negative result indicates a percentage decrease. For example, if a price goes from $100 to $80, the change is -20%.

Can I calculate change if the start value is zero?

Mathematically, percentage change from zero is undefined because you cannot divide by zero. However, it represents an infinite increase in practical terms.

Is this the same as percentage difference?

Not exactly. Percentage change implies a direction (old to new). Percentage difference usually compares two values without a specific order, often dividing the difference by the average of the two numbers.
