Calculate Percentages Instantly →Understanding the Basics of Percentages
A percentage is a way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when we say "15 percent," we mean 15 out of every 100.
Three Common Percentage Problems
There are primarily three types of percentage problems you'll encounter:
- Finding what percent of a number is: For example, what is 15% of 200?
- Determining what percentage one number is of another: For example, 30 is what percent of 150?
- Calculating percentage increase or decrease: For example, what is the percentage change from 80 to 100?
Let's explore each of these scenarios with examples.
Scenario 1: Finding What Percent of a Number Is
This is the most common type of percentage calculation. Here, you know the percentage and the total number, and you want to find out the portion represented by that percentage.
Formula
Percentage × Total Number = Result
Example
What is 25% of 300?
Using the formula: 0.25 (25% expressed as a decimal) × 300 = 75
Therefore, 25% of 300 is 75.
Simplify this calculation using our percentage calculator! Just enter the percentage and the total number to find the result instantly.
Scenario 2: Determining Percentage of One Number to Another
In this case, you have two numbers and need to express one as a percentage of the other.
Formula
(Part / Whole) × 100 = Percentage
Example
120 is what percent of 400?
Using the formula: (120 / 400) × 100 = 30%
So, 120 is 30% of 400.
Find out the answer quickly using our percentage calculator! Just enter the two numbers to determine the corresponding percentage.
Scenario 3: Calculating Percentage Increase or Decrease
This scenario involves finding the percentage change between two values, indicating how much something has increased or decreased.
Formula
((New Value - Old Value) / Old Value) × 100 = Percentage Change
Example
The price of a product increased from $50 to $60. What is the percentage increase?
Using the formula: (($60 - $50) / $50) × 100 = 20%
Therefore, the price increased by 20%.
Simplify this complex calculation using our percentage calculator! Enter the old and new values to instantly find out the percentage increase or decrease.
