Calculate Percentages Instantly →The Basic Formula
The most basic percentage problem involves finding what a certain percentage of a number is. The formula for this is:
Part = (Percentage / 100) * Whole
Let's say you want to find 15% of 200. Here's how you'd do it:
- Convert the percentage to a decimal: 15 / 100 = 0.15
- Multiply the decimal by the whole number: 0.15 * 200 = 30
- Therefore, 15% of 200 is 30.
With PercentageFinder.org, you can skip these steps! Simply enter 15% and 200 into the tool, and it will instantly display the answer.
Finding What Percentage One Number Is of Another
Sometimes, you need to know what percentage one number represents of another. For example, you might want to calculate what percentage 30 is of 150. The formula is:
Percentage = (Part / Whole) * 100
- Divide the part by the whole: 30 / 150 = 0.2
- Multiply the result by 100: 0.2 * 100 = 20
- Therefore, 30 is 20% of 150.
PercentageFinder.org simplifies this! Input the two numbers, and the tool will do the division and multiplication for you.
Calculating Percentage Increase or Decrease
Understanding percentage change is vital for analyzing trends and making informed decisions. These are the formulas involved:
Percentage Increase = [(New Value - Original Value) / Original Value] * 100
Percentage Decrease = [(Original Value - New Value) / Original Value] * 100
Imagine a product's price goes from $80 to $100.
- Calculate the difference: $100 - $80 = $20
- Divide the difference by the original value: $20 / $80 = 0.25
- Multiply by 100: 0.25 * 100 = 25%
- The price increased by 25%.
PercentageFinder.org instantly provides the percentage increase or decrease with the initial and final values.
