Calculate Percents Instantly →Understanding Percentages: The Basics
A percentage is simply a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." So, 25% means 25 out of every 100.
Three Common Percentage Problems
Most percentage problems fall into one of three categories. Our calculator handles them all with ease!
- Finding what percent of a number is: For example, what is 15% of 200?
- Finding 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?
Solving Percentage Problems Manually
While our calculator offers instant results, understanding the underlying math is always valuable. Here's how to tackle each type of problem:
1. Finding a Percentage of a Number
To find a percentage of a number, convert the percentage to a decimal and multiply. For example, to find 15% of 200:
- Convert 15% to a decimal: 15 / 100 = 0.15
- Multiply: 0.15 * 200 = 30
- Therefore, 15% of 200 is 30.
2. Finding What Percentage One Number Is of Another
To find what percentage one number is of another, divide the first number by the second and multiply by 100. For example, to find what percentage 30 is of 150:
- Divide: 30 / 150 = 0.2
- Multiply by 100: 0.2 * 100 = 20
- Therefore, 30 is 20% of 150.
3. Calculating Percentage Increase or Decrease
To calculate the percentage increase or decrease, use the following formula:
Percentage Change = [(New Value - Old Value) / Old Value] * 100
For example, to find the percentage change from 80 to 100:
- Subtract the old value from the new value: 100 - 80 = 20
- Divide by the old value: 20 / 80 = 0.25
- Multiply by 100: 0.25 * 100 = 25
- Therefore, the percentage change from 80 to 100 is a 25% increase.
