Calculate Percentages Instantly! →Understanding Percentages
A percentage is simply a way to express a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when you see 25%, it means 25 out of every 100.
Common Percentage Problems
Most percentage problems fall into one of three categories:
- Finding a Percentage of a Number: What is X% of Y? (e.g., What is 15% of 200?)
- Finding What Percentage One Number is of Another: X is what percent of Y? (e.g., 30 is what percent of 150?)
- Calculating Percentage Increase or Decrease: What is the percentage change from X to Y? (e.g., What is the percentage change from 80 to 100?)
Solving Percentage Problems Manually
While our calculator offers a super-fast solution, it's helpful to know how to calculate percentages manually. Here's a look at the formulas:
- Finding a Percentage of a Number: (X / 100) * Y
- Finding What Percentage One Number is of Another: (X / Y) * 100
- Calculating Percentage Change: ((Y - X) / X) * 100
Where:
- X = The first number
- Y = The second number or the total amount
Let's Look at Some Examples:
- What is 20% of 80?
(20 / 100) * 80 = 16. So, 20% of 80 is 16. - 10 is what percent of 50?
(10 / 50) * 100 = 20%. So, 10 is 20% of 50. - What is the percentage increase from 50 to 75?
((75 - 50) / 50) * 100 = 50%. So, the increase is 50%.
