Percentage Difference Calculator
Calculate the percentage difference between two values. This is useful when comparing two numbers where neither is explicitly an "original" or "reference" value, such as comparing two different measurements, prices, or statistics. The formula shows how different two values are relative to their average.
Understanding Percentage Difference
Percentage difference is a way to express the difference between two values relative to their average. It's particularly useful when you're comparing two items and there's no obvious "original" or "reference" value (unlike percent change, which measures change from an old value to a new value).
For example, you might use it to:
- Compare the prices of the same product at two different stores.
- Compare statistical data points from two different groups or time periods where order doesn't matter.
- Analyze the variance between two measurements.
