At its core, a percentage is 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 you see a statement like "15% of 200," it means 15 out of every 100 parts of 200.
Three Common Percentage Problems
Many percentage-related problems fall into one of three categories. Fortunately, our percentage calculator can solve all three with ease:
- Finding a Percentage of a Number: This involves determining what a specific percentage of a given number is. For example, what is 15% of 200?
- Finding What Percentage One Number Is of Another: This is about expressing one number as a percentage of another. For example, 30 is what percent of 150?
- Calculating Percentage Increase or Decrease: This calculates the percentage change between two values. For example, what is the percentage increase from 80 to 100?
Manual Calculation: The Percentage Formula
While our calculator offers a convenient solution, understanding the underlying formula is essential. The basic percentage formula is:
Percentage = (Part / Whole) × 100
Where:
- Part: The specific value you are interested in.
- Whole: The total value or the original number.
Examples of Percentage Calculations
Let's illustrate each type of problem with examples:
- Example 1: Finding a Percentage of a Number
Problem: What is 25% of 80?
Solution: (25 / 100) × 80 = 20. Therefore, 25% of 80 is 20.
- Example 2: Finding What Percentage One Number Is of Another
Problem: 12 is what percent of 48?
Solution: (12 / 48) × 100 = 25%. Therefore, 12 is 25% of 48.
- Example 3: Calculating Percentage Increase
Problem: A price increased from $50 to $60. What is the percentage increase?
Solution: ((60 - 50) / 50) × 100 = 20%. Therefore, the price increased by 20%.

Converting Between Percentages, Decimals, and Fractions
Percentages, decimals, and fractions are interchangeable ways to represent proportions. Knowing how to convert between them enhances your understanding of numerical relationships. For example, to convert a percentage to a decimal, divide by 100 (e.g., 75% = 0.75). To convert a decimal to a percentage, multiply by 100 (e.g., 0.62 = 62%).
