Calculate percentages, discounts, and percentage changes easily
A percentage calculator helps you quickly compute percentages, discounts, and percentage changes. Whether you're calculating what percentage one number is of another, determining the final price after a discount, or finding the percentage change between two values, our calculator makes these calculations simple and accurate.
Percentages are used in everyday situations from shopping discounts to financial analysis. Our tool supports multiple calculation types to meet your needs.
Basic Formula:
📊 Example:
If you scored 85 points out of 100:
Percentage = (85 / 100) × 100 = 85%
Percentage of a Number:
Finding what percentage one number is of another. Example: 25 is what % of 100? Answer: 25%
Discount Calculation:
Finding the final price after a percentage discount. Example: 20% off $100 = $80
Percentage Change:
Measuring how much a value has increased or decreased. Example: From 50 to 75 = 50% increase
How do I calculate a percentage increase?
Use the formula: ((New Value - Old Value) / Old Value) × 100. For example, increasing from 50 to 75: ((75-50)/50) × 100 = 50%
What's the difference between percentage and percentage points?
Percentage points measure absolute differences (e.g., 10% to 15% is a 5 percentage point increase), while percentage measures relative change.
Can percentages exceed 100%?
Yes! Percentages can exceed 100%. For example, if a value doubles, that's a 100% increase, and if it triples, that's a 200% increase.
