Calculate Percentages Now →Understanding the Basics of Percentages
A percentage is simply a way to express a number as a fraction of 100. For example, 50% means 50 out of 100, or one-half. Understanding this basic concept is crucial for performing more complex percentage calculations.
Three Common Percentage Problems
There are three main types of percentage problems you might encounter:
- Finding What Percent of a Number Is: What is 15% of 200?
- Determining What Percentage One Number Is of Another: 30 is what percent of 150?
- Calculating Percentage Increase or Decrease: Going from 80 to 100 is what percentage increase?
Solving Percentage Problems Manually
While our calculator makes this process much faster, understanding the manual calculation can be helpful:
Finding X Percent of Y
To find X% of Y, convert X% to a decimal (by dividing by 100) and then multiply by Y. For example, to find 15% of 200:
15 / 100 = 0.15
0.15 * 200 = 30
So, 15% of 200 is 30.
Determining What Percentage X Is of Y
To find what percentage X is of Y, divide X by Y, and then multiply by 100. For example, to find what percentage 30 is of 150:
30 / 150 = 0.2
0.2 * 100 = 20%
So, 30 is 20% of 150.
Calculating Percentage Increase or Decrease
To calculate the percentage increase or decrease between two numbers, use the following formula: ((New Value - Old Value) / Old Value) * 100. For example, to calculate the percentage increase from 80 to 100:
((100 - 80) / 80) * 100 = 25%
So, going from 80 to 100 is a 25% increase. Read more about calculating percentage increase at calculate percentage increase.

Understanding Percentage Difference vs Percentage Change
It's important to note the subtle difference between percentage difference and percentage change. Percentage difference, as previously mentioned, compares two values without indicating direction. It's ideal when you want to understand the extent of variation between two quantities, regardless of whether one is greater than the other. For example, comparing the number of employees in two companies.
On the other hand, percentage change emphasizes the direction and magnitude of the change from an initial value to a final value. It is typically expressed as an increase or decrease. This measurement is suitable when you want to track how something evolves over time or after an event.
Beyond Basic Calculations
Once you master the basics, you can tackle more complex percentage problems, such as compound interest calculations or determining the percentage composition of a mixture. No matter the complexity, our calculators are here to assist you.
