What Is a Percentage?
A percentage represents a number as a fraction of 100. The word percent means “per hundred.”
For example:
- 10% means 10 out of 100.
- 25% means 25 out of 100.
- 50% means 50 out of 100.
- 100% represents the complete amount.
Percentages are commonly used for discounts, marks, profits, losses, salary increases, taxes, interest rates, statistics, and many other calculations.
How to Calculate a Percentage
The basic percentage formula is:
Percentage = (Part ÷ Total) × 100
For example, if you scored 75 marks out of 100:
(75 ÷ 100) × 100 = 75%
Therefore, your percentage is 75%.
What Is X% of Y?
To find a specific percentage of a number, use:
X% of Y = (X ÷ 100) × Y
For example:
25% of 200 = (25 ÷ 100) × 200 = 50
So, 25% of 200 is 50.
What Percentage Is X of Y?
To find what percentage one number represents of another:
Percentage = (X ÷ Y) × 100
For example, if you want to know what percentage 50 is of 200:
(50 ÷ 200) × 100 = 25%
Therefore, 50 is 25% of 200.
How to Calculate Percentage Increase
Percentage increase tells you how much a value has increased compared with its original value.
The formula is:
Percentage Increase = ((New Value − Original Value) ÷ Original Value) × 100
For example, if a price increases from ₹100 to ₹150:
((150 − 100) ÷ 100) × 100 = 50%
The increase is 50%.
How to Calculate Percentage Decrease
Percentage decrease tells you how much a value has decreased compared with its original value.
The formula is:
Percentage Decrease = ((Original Value − New Value) ÷ Original Value) × 100
For example, if a product’s price decreases from ₹200 to ₹150:
((200 − 150) ÷ 200) × 100 = 25%
The price has decreased by 25%.
