Percentage variance helps you understand the scale of change between two numbers, showing the degree of difference in percentage terms. It's not just for academics; it's crucial for anyone tracking changes in business, finance, or everyday life. For instance, understanding percentage variance can help you analyze sales growth, budget deviations, or even the difference in your weight over time. Our percentage variance calculator simplifies this, providing instant results.

It's easy to confuse percentage variance with percentage change. While both measure change, they do so from different perspectives. Percentage change looks at the change from an initial value to a final value, emphasizing the direction of the change (increase or decrease). On the other hand, percentage variance focuses on the difference between two values relative to their average. It is non-directional and focuses on the magnitude of the difference between the two values. If you are looking to understand percentage change check out our handy percentage change calculator.
How to Calculate Percentage Variance
Here's the formula to calculate percentage variance:
Percentage Variance = (|Value 1 - Value 2| / ((Value 1 + Value 2) / 2)) * 100
Let's break it down:
- Find the Difference: Subtract one value from the other and take the absolute value (ignore the negative sign if the result is negative).
- Calculate the Average: Add both values and divide by 2.
- Divide: Divide the absolute difference by the average.
- Multiply by 100: Convert the result to a percentage.
For example, let’s say you want to compare the number of employees between two departments. Department A has 55 employees, and Department B has 65 employees. The percentage variance is calculated as follows:
Percentage Variance = (|55 - 65| / ((55 + 65) / 2)) * 100 = (10 / (120 / 2)) * 100 = (10 / 60) * 100 ≈ 16.67%

When is Percentage Variance Useful?
Percentage variance is especially handy when you want to compare two values without emphasizing which one is "better" or "worse." It’s suitable for situations where you're interested in the relative difference rather than the direction of change, for example:
- Comparing product prices from two different vendors.
- Analyzing the difference in test scores between two groups of students.
- Assessing the variation in project costs estimated by two different teams.
However, keep in mind that percentage variance isn't ideal for tracking changes over time or when you want to highlight increases or decreases. In those cases, you should use percentage change instead.
