Calculate Percentages Now →What is a Percentage?
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 you see a percentage, you can think of it as a part of 100. For example, 25% means 25 out of 100.
Three Common Percentage Problems
Most percentage problems fall into one of these three categories:
- 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 A to B? (e.g., What is the percentage change from 80 to 100?)
How to Calculate Percentages Manually
Here's a breakdown of how to solve each type of percentage problem manually:
1. Finding a Percentage of a Number
To find P% of X, use the formula: (P/100) * X = Result
Example: What is 15% of 200?
- Convert the percentage to a decimal: 15% = 15/100 = 0.15
- Multiply the decimal by the number: 0.15 * 200 = 30
- Therefore, 15% of 200 is 30.
2. Finding What Percentage One Number Is of Another
To find what percentage Y is of X, use the formula: (Y / X) * 100 = P%
Example: 30 is what percent of 150?
- Divide the first number by the second number: 30 / 150 = 0.2
- Multiply the result by 100: 0.2 * 100 = 20
- Therefore, 30 is 20% of 150.
3. Calculating Percentage Increase or Decrease
To find the percentage change from A to B, use the formula: ((B - A) / A) * 100 = Percentage Change
Example: What is the percentage change from 80 to 100?
- Subtract the original value from the new value: 100 - 80 = 20
- Divide the result by the original value: 20 / 80 = 0.25
- Multiply by 100: 0.25 * 100 = 25
- Therefore, the percentage increase from 80 to 100 is 25%.

Real-World Applications
Understanding how to calculate percentages has practical applications in everyday life:
- Shopping: Calculate discounts and sale prices quickly. Find out what percentage you are really saving.
- Finance: Determine investment returns or calculate interest rates.
- Tipping: Easily calculate a 20 percent tip or other amounts at restaurants.
- Cooking: Scale recipes up or down by adjusting ingredient quantities proportionally.
- Data Analysis: Interpret survey results or analyze statistical data.
Beyond the Basics: Percentage Change
One of the most valuable applications of percentages is in understanding change. Whether you're tracking the percentage increase in your website traffic or the percentage decrease in your energy bill, percentages provide a clear way to visualize trends. Consider this example:
Example: A stock increases in value from $50 to $60. What is the percentage gain?
- Calculate the difference: $60 - $50 = $10
- Divide the difference by the original value: $10 / $50 = 0.2
- Multiply by 100 to express as a percentage: 0.2 * 100 = 20%
- Therefore, the stock has increased by 20%.
