How to Calculate Comparison Percentage

The Formula for Calculating Comparison Percentage

There are several ways to compare percentages. Here is the formula that our calculator uses:

Comparison Percentage = (|Value 1 - Value 2| / ((Value 1 + Value 2) / 2)) * 100

Let's break down this formula:

1. Find the Absolute Difference: Subtract the smaller value from the larger value to get a positive difference.
2. Calculate the Average: Add the two values together and divide by 2.
3. Divide and Multiply: Divide the absolute difference by the average, and then multiply by 100 to express the result as a percentage.

Step-by-Step Guide to Calculating Comparison Percentage

Let's illustrate with an example: Suppose you want to compare the price of a product at two different stores. Store A sells it for $80, while Store B sells it for $100.

1. Identify the Values: Value 1 = $80, Value 2 = $100
2. Calculate the Absolute Difference: |$80 - $100| = $20
3. Calculate the Average: ($80 + $100) / 2 = $90
4. Divide and Multiply: ($20 / $90) * 100 = 22.22%

Therefore, the comparison percentage between the prices is 22.22%.

When to Use Comparison Percentage

The comparison percentage is most useful when:

• You want to understand the relative difference between two values without emphasizing which one is “better” or “worse.”
• The two values are of a similar type and scale (e.g., comparing prices of the same product, comparing sales figures in similar time periods).

This method is different from percentage change. For example, a percentage change can be found on the page about calculating percentage increase.
