Calculate Percentages Instantly →Understanding Percentages
At its core, 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.
Percentages offer a standardized way to compare different quantities, making it easier to grasp relationships and make informed decisions. They are a dimensionless relationship between two numbers, similar to fractions and decimals.
Three Common Percentage Problems – Solved!
Most percentage questions fall into one of three categories. Luckily, our percentage calculator handles them all with ease:
- Finding a Percentage of a Number: What is 15% of 200?
- Finding What Percentage One Number is of Another: 30 is what percent of 150?
- Calculating Percentage Increase or Decrease: What is the percentage change from 80 to 100?
Solving these types of problems manually is as simple as using formulas. But why bother when our tool can do it for you instantly? Simply enter the values and get the answer.
Calculating Percentages Manually: The Formulas
While our percentage calculator is the quickest option, understanding the formulas can be helpful. Here’s a breakdown:
1. Finding a Percentage of a Number
To find P% of X, use the formula: Y = (P/100) * X
Example: What is 10% of 150?
Y = (10/100) * 150 = 0.10 * 150 = 15
2. Finding What Percentage One Number is of Another
To find what percent of X is Y, use the formula: P = (Y/X) * 100
Example: What percent of 60 is 12?
P = (12/60) * 100 = 0.20 * 100 = 20%
3. Finding X if P Percent of it is Y
To find X if P% of it is Y, use the formula: X = Y / (P/100)
Example: 25 is 20% of what number?
X = 25 / (20/100) = 25 / 0.20 = 125
