Mathematics, science, finance will all require a basic understanding of the concept called percent difference. Comparing exam scores, prices, measurements or analyzing scientific data would require a method of exemplifying the differences between two amounts in a percentage by using the concept of percent difference.
Many students will confuse the concept of percent difference with percent change; however they do not mean the same thing. This guide will provide information about the percent difference formula, how to calculate a percent difference, using a percent difference calculator, and how to solve simple examples in step by step fashion.
What Is the Percent Difference?
Definition of Percent Difference
The difference between two numbers in relation to their average value is measured by percent difference. This value tells us how many percent apart two numbers are.
Examples of percent difference are:
- Comparing exam scores
- Comparing prices of two products
- Comparing physics measurements, etc.
The percent difference is positive because we are using an absolute value for the difference.
Where:
- a = first value
- b = second value
- |a − b| = absolute difference
- Multiply by 100 to convert into percentage
This formula is also known as the percent difference equation.
How to Calculate Percent Difference
Many students ask how to calculate percent differences easily. Follow these simple steps.
Step 1: Find the Difference Between Numbers
Subtract the two values.
Example:
20−30=10
The difference is 10.
Step 2: Find the Average
Add the numbers and divide by 2.
20+30/2= 25
The average is 25.
Step 3: Divide Difference by Average
10/25= 0.4
Step 4: Multiply by 100
0.4 x 100= 40
Final Answer
The percent difference is 40%.
Difference in Percentage vs. Percentage of Change
The percentage of difference and percentage of change can often be confused by students
Percentage of Difference
- Two values compared equally
- Average value is used
- No directional measurement (positive or negative)
Percentage of Change
- Calculating change (increase or decrease)
- Uses original value of item
- Direction is important
Feature | Percent Difference | Percent Change |
Uses average? | Yes | No |
Measures increase/decrease? | No | Yes |
Always positive? | Yes | Not always |
