Percentages are a fundamental part of everyday life. From calculating discounts at your favorite store to understanding statistics, knowing how to work with percentages is a valuable skill. But what exactly is a percentage? A percentage is simply a way of expressing a number as a fraction of 100. The word "percent" literally means "per hundred." So, when we say "15 percent," we mean 15 out of every 100.

Calculate Percentages Now! →Three Common Percentage Problems
While there are many ways to use percentages, three problems pop up more often than others. Fortunately, solving them doesn't have to be a chore. With the right approach, and the right tool, you can get the answers you need in seconds.
- Finding a Percentage of a Number: This is the classic "what is X% of Y" problem. For example, "What is 15% of 200?"
- Finding What Percentage One Number Is of Another: This is the "X is what percent of Y" problem. For example, "30 is what percent of 150?"
- Calculating Percentage Increase or Decrease: This involves finding the percentage change between two values. For example, "What is the percentage increase from 80 to 100?"
Manual Calculation Methods
While our calculator provides instant answers, it's useful to understand the underlying math. Here's how to solve these problems manually:
- Finding a Percentage of a Number: Convert the percentage to a decimal (divide by 100) and multiply by the number. So, to find 15% of 200, convert 15% to 0.15, then multiply 0.15 * 200 = 30.
- Finding What Percentage One Number Is of Another: Divide the first number by the second number and multiply by 100. So, to find what percent 30 is of 150, divide 30 by 150 (30 / 150 = 0.2), then multiply by 100 (0.2 * 100 = 20%).
- Calculating Percentage Increase or Decrease: Find the difference between the two numbers, divide by the original number, and multiply by 100. So, to find the percentage increase from 80 to 100, first find the difference (100 - 80 = 20), then divide by the original number (20 / 80 = 0.25), then multiply by 100 (0.25 * 100 = 25%).
