Where:

• Part — The portion of the whole you want to measure
• Whole — The total or complete amount
• 100 — Multiplier to convert to percentage

Explanation: The formula divides the part by the whole to get a decimal, then multiplies by 100 to convert it to a percentage.

Q4: How do I calculate percentage change?
A: Percentage change = [(New Value - Old Value) / Old Value] × 100

Q5: What are common percentage calculation errors?
