Calculate Percentages Instantly →Understanding Percentages
A percentage is a way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "out of one hundred." It's a standardized way to represent proportions, making it easier to compare different ratios. For example, saying "25%" is the same as saying "25 out of 100" or "one quarter."
Three Common Percentage Problems
There are three primary types of percentage problems you might encounter:
- Finding what percent of a number is: For example, what is 15% of 200?
- Determining 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?
Fortunately, solving these problems is straightforward, especially with the right tools.

The formula used here is: Percentage = (Part / Whole) * 100
3. Calculating Percentage Increase or Decrease
This function computes the percentage change between two values, whether it's an increase or a decrease. Enter the initial and final values, and the calculator will display the percentage change.
The formulas for this are:
- Percentage Increase:
