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, when we say 25%, we mean 25 out of every 100.
Three Common Percentage Problems
Most percentage-related questions fall into one of these three categories. Fortunately, our calculator handles them all:
- Finding a percentage of a number: What is P% of X? (e.g., What is 15% of 200?)
- Finding what percentage one number is of another: Y is what percent of X? (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 increase from 80 to 100?)
Methods for Determining Percentages
While manual calculation is possible, a percentage calculator like ours offers speed and accuracy. Here's a look at both:
Manual Calculation
The underlying formulas for percentage calculations are relatively straightforward:
- Percentage of a number: (P/100) * X = Result
- Percentage of one number to another: (Y / X) * 100 = Percentage
- Percentage increase/decrease: ((Y - X) / X) * 100 = Percentage Change
For example, to find what percentage 30 is of 150, you would divide 30 by 150 (0.2) and then multiply by 100, resulting in 20%. You can also utilize our Decimal to Percent Calculator: /blog/decimal-to-percentage-calculator
