THE BASICS
What is a Percentage?
A percentage is a simple way to express any number as a part of 100. It is commonly used to represent a portion of a whole or to compare two numbers. Percentages are often denoted by the "%" symbol. For example, if a farmer has 100 goats and 25 of them are black, we can say that 25% of the goats are black. Percentages are used in various contexts, such as discounts, interest rates, statistics, and test scores.

Percentage Calculator FAQs
How do I calculate a percentage of a number?
Multiply the percentage by the number and divide by 100. For example, 30% of 500 is (30 × 500) ÷ 100 = 150.
How do I find what percentage one number is of another?
Divide the part by the whole and multiply by 100. For example, 325 out of 500 is (325 ÷ 500) × 100 = 65%. The whole must not be zero.
How do I calculate a discount?
Multiply the original price by the discount percentage and divide by 100. Subtract that discount amount from the original price to get the sale price before tax.
How do I calculate percentage increase?
Subtract the original value from the new value, divide the difference by the original value, and multiply by 100. This formula requires a non-zero original value.
Can a percentage be greater than 100%?
Yes. A percentage can exceed 100% when a part is larger than the reference whole. For example, 150 out of 100 is 150%.
How do I find the original price before a discount?
Divide the discounted price by 1 minus the discount rate expressed as a decimal. For example, $60 after a 25% discount means the original price was $60 ÷ 0.75 = $80.
