How to Calculate Percentages
This calculator supports three common percentage calculations:
1. What is X% of Y?
Result = (Percentage / 100) × Number
Example: 25% of 200 = (25/100) × 200 = 50
2. X is what percent of Y?
Percentage = (Part / Whole) × 100
Example: 50 is what % of 200 = (50/200) × 100 = 25%
3. Percentage Change
% Change = [(New - Old) / Old] × 100
Example: From 100 to 150 = [(150-100)/100] × 100 = 50% increase
Percentage Calculation Examples
- 20% of 500 = 100
- 15% of 1200 = 180
- 75 is 25% of 300
- Change from 80 to 100 = 25% increase
- Change from 100 to 80 = 20% decrease

Frequently Asked Questions
-
To find X% of Y, multiply Y by X and divide by 100. For example, 20% of 150 = (150 × 20) / 100 = 30.
-
Percentage increase = ((New Value - Old Value) / Old Value) × 100. For example, if a price goes from ₹100 to ₹120, the increase is ((120-100)/100) × 100 = 20%.
-
Percentage decrease = ((Old Value - New Value) / Old Value) × 100. For example, if a price drops from ₹200 to ₹150, the decrease is ((200-150)/200) × 100 = 25%.
-
Percentage is a fraction of 100 (like scoring 80% on a test). Percentile indicates the value below which a given percentage of observations fall (like being in the 90th percentile means you scored better than 90% of people).
-
Divide the numerator by the denominator and multiply by 100. For example, 3/4 = 0.75 × 100 = 75%.
