At its core, a percentage is a way to express a number as a fraction of 100. The word "percent" literally means "per hundred." So, 50% is the same as 50/100, or one half. Percentages are used to represent proportions, compare values, and express changes.
Three Common Percentage Problems
There are primarily three types of percentage problems you might encounter. Luckily, our handy calculator can solve all of them with just a few clicks!
- 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?)
How to Calculate Percentages Manually
While our calculator makes things quick and easy, it's helpful to understand the underlying math. Here's how to tackle each type of problem manually:
- Finding a Percentage of a Number: Multiply the number by the percentage (expressed as a decimal). For example, to find 15% of 200, multiply 200 by 0.15 (15/100), which equals 30.
- Finding What Percentage One Number is of Another: Divide the first number by the second number, then multiply by 100. For example, to find what percentage 30 is of 150, divide 30 by 150 (0.2) and then multiply by 100, resulting in 20%.
- Calculating Percentage Increase or Decrease: First, find the difference between the two numbers. Then, divide that difference by the original number (the starting value). Finally, multiply by 100. For example, to find the percentage change from 80 to 100, calculate the difference (100 - 80 = 20), divide by the original number (20 / 80 = 0.25), and multiply by 100, resulting in a 25% increase.
