Calculate Percentages Now →Understanding the Basics
Before diving into calculations, let's clarify what a percentage represents. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." Therefore, a percentage is a way of expressing a number as a fraction of 100.
Three Common Percentage Problems
Most percentage problems fall into one of these categories:
- Finding a percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Determining what percentage one number is of another: X is what percent of Y? (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 change from 80 to 100?)
Fortunately, our percentage calculator can solve these types of questions with ease. However, learning the manual method gives you a solid understanding of what's going on behind the scenes.
Step-by-Step Solutions
Here's how to tackle each type of problem:
1. Finding a Percentage of a Number
Problem: What is X% of Y?
- Convert the percentage to a decimal: Divide X by 100 (X / 100).
- Multiply the decimal by the number: Multiply the result by Y.
Example: What is 25% of 80?
- Convert 25% to a decimal: 25 / 100 = 0.25
- Multiply: 0.25 * 80 = 20
Answer: 25% of 80 is 20.
Of course, you could always use our percentage calculator for this type of calculation
2. Determining What Percentage One Number Is of Another
Problem: X is what percent of Y?
- Divide the first number by the second number: Divide X by Y (X / Y).
- Multiply the result by 100: Multiply the result by 100 to express it as a percentage.
Example: 12 is what percent of 48?
- Divide: 12 / 48 = 0.25
- Multiply by 100: 0.25 * 100 = 25
Answer: 12 is 25% of 48.

3. Calculating Percentage Increase or Decrease
Problem: What is the percentage change from X to Y?
- Find the difference between the two numbers: Subtract the original number (X) from the new number (Y): Y - X.
- Divide the difference by the original number: Divide the result by the original number (X): (Y - X) / X.
- Multiply the result by 100: Multiply by 100 to express it as a percentage.
Example: What is the percentage change from 50 to 75?
- Find the difference: 75 - 50 = 25
- Divide by the original number: 25 / 50 = 0.5
- Multiply by 100: 0.5 * 100 = 50
Answer: The percentage change from 50 to 75 is a 50% increase.
