Calculate Percentage Difference Now →What is Percentage Difference?
The percentage difference represents the relative difference between two values, expressed as a percentage. It's particularly useful when you want to understand the magnitude of the difference irrespective of direction (increase or decrease). This differs from percentage change, where direction matters.
The Formula for Percentage Difference
The formula to calculate the percentage difference is as follows:
Percentage Difference = (|Value A - Value B| / ((Value A + Value B) / 2)) * 100
Where:
- |Value A - Value B| represents the absolute value of the difference between the two numbers.
- ((Value A + Value B) / 2) represents the average of the two numbers.
Steps to Calculate the Percentage Difference
- Find the Absolute Difference: Subtract the smaller number from the larger number. Take the absolute value to ensure a positive result.
- Calculate the Average: Add the two numbers together and divide by 2.
- Divide the Difference by the Average: Divide the absolute difference (step 1) by the average (step 2).
- Multiply by 100: Multiply the result by 100 to express the difference as a percentage.
Example Calculation
Let's say you want to find the percentage difference between 120 and 150.
- Absolute Difference: |150 - 120| = 30
- Average: (150 + 120) / 2 = 135
- Divide: 30 / 135 = 0.2222
- Multiply by 100: 0.2222 * 100 = 22.22%
Therefore, the percentage difference between 120 and 150 is 22.22%.
Common Use Cases
- Comparing sales figures: See how much two months' sales differ relative to their average.
- Analyzing experimental data: Evaluate the variation between observed and expected results.
- Assessing price differences: Determine the percentage discrepancy between prices from different suppliers.
- Error analysis: Understanding how a mistake impacts the overall calculations.

Percentage Change vs. Percentage Difference
It's important to distinguish between /blog/percentage-increase-calculator and percentage difference.
- Percentage Change measures the relative change from an initial value to a final value. The order of values matters as it indicates an increase or decrease from a starting point.
- Percentage Difference, as discussed above, treats both values equally and expresses the relative difference between them without implying a direction.
