How to Calculate Percentages
A percentage is a way to express a number as a fraction of 100. The word "percent" literally means "per hundred".
Formula: What is X% of Y?
Result = (X / 100) × Y
Example: What is 15% of 200?
Result = (15 / 100) × 200 = 30
Formula: X is what % of Y?
Result = (X / Y) × 100
Example: 25 is what % of 200?
Result = (25 / 200) × 100 = 12.5%
Formula: Percentage Change
Result = ((New - Old) / Old) × 100
Example: From 100 to 150
Result = ((150 - 100) / 100) × 100 = 50% increase
