5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase is the simple difference (new - old), while percentage increase shows this difference relative to the original value.

Q2: Can the result be negative?
A: Yes, a negative result indicates a percentage decrease rather than an increase.

Q3: Why do we multiply by 100?
A: Multiplying by 100 converts the decimal fraction to a percentage, which is easier to interpret.

Q4: What if the old value is zero?
A: The calculation is undefined when old value is zero, as division by zero is impossible.

Q5: How is this different from percentage points?
A: Percentage points measure absolute difference between percentages, while percentage increase measures relative change from an original value.
