Percentage Difference Calculator (Two Values)
When comparing two measurements where neither is an original baseline (such as two product prices or experimental runs), calculate the true symmetric percentage difference.
How to Use Percentage Difference Calculator
Enter Value 1 (V1)
Type your first measurement or number.
Enter Value 2 (V2)
Type your second measurement or number.
View Difference
Inspect percentage difference, absolute difference, and average base.
About Percentage Difference Calculator
Unlike percentage change which divides by an initial value V1, percentage difference divides the absolute difference by the arithmetic mean of both values: |V1 - V2| / ((V1 + V2)/2) * 100%.
