A percentage is simply a way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when you see 25%, it means 25 out of every 100.
Three Common Percentage Problems
Calculating value in percentage typically involves solving one of three common problems:
- Finding what percent of a number is. For example, what is 15% of 200?
- Determining what percentage one number is of another. For example, 30 is what percent of 150?
- Calculating percentage increase or decrease. For example, what is the percentage change from 80 to 100?

Percentage Formulas Explained
While our calculator automates the process, understanding the underlying formulas can be helpful:
- Finding a percentage of a number: (Percentage / 100) * Number
- Finding what percentage one number is of another: (Part / Whole) * 100
- Calculating percentage change: ((New Value - Old Value) / Old Value) * 100
Examples
- What is 20% of 75? (20 / 100) * 75 = 15
- 45 is what percent of 90? (45 / 90) * 100 = 50%
- What is the percentage increase from 50 to 75? ((75 - 50) / 50) * 100 = 50%
