FAQ
What is a percentage?
A percentage shows a part of something, out of 100. For example, if you have 100 balls and 25 are red, that means 25% of the balls are red. The percent sign is this: %.
How do you calculate a percentage?
Use this simple percentage formula:
(Part ÷ Total) × 100
Let’s say you ate 20 of 50 cookies. Divide 20 by 50 = 0.4. Now, multiply 0.4 × 100 = 40%.
You can skip the math by using our percentage calculator online. Just type in your numbers — and done!
What is a percentage increase?
A percentage increase shows how much something has grown.
Use this formula:
((New Number – Old Number) ÷ Old Number) × 100
For example, if a price goes from $100 to $120, that’s a 20% increase. Try our percentage increase calculator to save time!
