What Is a Percentage?

A percentage is a way of expressing a number as a part of 100. The word percentage means "per hundred," and the symbol used to represent it is %.

For example, 25% means 25 out of 100. As a decimal, 25% is equal to 0.25, and as a fraction it can be written as 1/4.

How to Calculate a Percentage of a Number

To calculate a percentage of a number, multiply the number by the percentage and divide by 100.

Example:
What is 20% of 500?

20 ÷ 100 × 500 = 100

This type of calculation is commonly used for discounts, taxes, tips, commissions, interest and other percentage-based amounts.

How to Calculate What Percentage One Number Is of Another

To find what percentage one number represents of another number, divide the first number by the second number and multiply the result by 100.

Example:
25 is what percentage of 200?

25 ÷ 200 × 100 = 12.5%

Therefore, 25 represents 12.5% of 200.

How to Calculate Percentage Increase

Percentage increase tells you how much a value has increased compared with its original value.

Subtract the original value from the new value. Divide that difference by the original value and multiply by 100.

Example:
A price increases from 100 to 125.

(125 − 100) ÷ 100 × 100 = 25%

The value therefore increased by 25%.

How to Calculate Percentage Decrease

Percentage decrease tells you how much a value has decreased compared with its original value.

Example:
A price decreases from 200 to 150.

(200 − 150) ÷ 200 × 100 = 25%

The value therefore decreased by 25%.

What Is Percentage Difference?

Percentage difference is used when comparing two values and neither value is considered the original or starting value.

It is calculated by taking the absolute difference between the two values, dividing it by their average, and multiplying by 100.

Example:
Compare 80 and 100.

Difference = 20
Average = 90
20 ÷ 90 × 100 = 22.22%

Percentage Calculator for Discounts

Percentage calculations are frequently used when shopping. If a product costs 200 and has a 15% discount, the discount amount is 30.

Subtracting the discount from the original price gives a final price of 170.

Example:
Original price = 200
Discount = 15%
Discount amount = 30
Final price = 170

Percentage Calculator for Taxes and Tips

Percentages are also commonly used to calculate taxes, tips, service charges and other additional costs.

Example:
Bill = 50
Tip = 10%
Tip amount = 5
Total = 55
