Calculate Percentages Instantly →Understanding the Basics
Before diving into the calculator, it's helpful to remember what a percentage represents. A percentage is simply a fraction out of 100. So, 20% is equivalent to 20/100, or 0.20 as a decimal.
Finding a Percentage of a Number
This is one of the most common percentage calculations. Here's how to find what a certain percentage of a number is:
- Convert the percentage to a decimal: Divide the percentage by 100. For example, to convert 15% to a decimal, divide 15 by 100, which equals 0.15.
- Multiply: Multiply the decimal by the number you want to find the percentage of. For instance, to find 15% of 200, multiply 0.15 by 200, which equals 30.
Example: What is 25% of 80?
- Convert 25% to a decimal: 25 / 100 = 0.25
- Multiply: 0.25 x 80 = 20
- Therefore, 25% of 80 is 20.
Calculating What Percentage One Number Is of Another
Sometimes, you need to determine what percentage one number represents out of a total:
- Divide: Divide the first number (the part) by the second number (the whole). For example, if you want to know what percentage 30 is of 150, divide 30 by 150, which equals 0.2.
- Convert to Percentage: Multiply the result by 100. So, 0.2 multiplied by 100 equals 20%.
Example: 12 is what percent of 48?
- Divide: 12 / 48 = 0.25
- Multiply by 100: 0.25 x 100 = 25%
- Therefore, 12 is 25% of 48.
Finding Percentage Increase or Decrease
Percentage change is useful for understanding growth or reduction. Here's how to calculate it:
- Find the difference: Subtract the original value from the new value.
- Divide by the original value: Divide the difference by the original value.
- Multiply by 100: Multiply the result by 100 to express it as a percentage.
Formula: Percentage Change = ((New Value - Original Value) / Original Value) * 100
Example: A price increases from $80 to $100. What is the percentage increase?
- Find the difference: $100 - $80 = $20
- Divide by the original value: $20 / $80 = 0.25
- Multiply by 100: 0.25 x 100 = 25%
- Therefore, the price increased by 25%.
