Calculate Percentages Now! →Understanding Percentage Basics
Before diving into calculator usage, let's recap what a percentage represents. A percentage is a way of expressing a number as a fraction of 100. The word "percent" literally means "per hundred." Thus, 25% is equivalent to 25/100 or 0.25.
Three Common Percentage Problems
There are generally three types of percentage problems you might encounter:
- 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 on a Basic Calculator
If you're using a basic calculator, you can still solve percentage problems by understanding the underlying math.
Finding a Percentage of a Number
To find X% of Y, multiply Y by (X/100). For example, to find 15% of 200:
- Divide 15 by 100: 15 / 100 = 0.15
- Multiply 200 by 0.15: 200 * 0.15 = 30
- Therefore, 15% of 200 is 30.
Finding What Percentage One Number Is of Another
To find what percentage X is of Y, divide X by Y, then multiply by 100. For example, to find what percentage 30 is of 150:
- Divide 30 by 150: 30 / 150 = 0.2
- Multiply 0.2 by 100: 0.2 * 100 = 20
- Therefore, 30 is 20% of 150.
Calculating Percentage Increase or Decrease
To find the percentage change from X to Y:
- Subtract X from Y: Y - X
- Divide the result by X: (Y - X) / X
- Multiply by 100: ((Y - X) / X) * 100
For example, to find the percentage change from 80 to 100:
- Subtract 80 from 100: 100 - 80 = 20
- Divide 20 by 80: 20 / 80 = 0.25
- Multiply 0.25 by 100: 0.25 * 100 = 25
- Therefore, the percentage change from 80 to 100 is a 25% increase.
