Relative Percent Difference (RPD) Calculator





Formula

To calculate the Relative Percent Difference (RPD):

RPD=|X2X1|(X2+X12)×100

Where:

What is RPD?

RPD, short for relative percent difference, is a measure of the change in a value relative to the average of that value. For example, if a value in an experiment changed from 10 to 20, the RPD would be relative to the average of those two numbers. 10+202=15.

Example Calculation 1

Let's assume the following values:

Step 1: Calculate the relative percent difference:

RPD=|2010|(20+102)×100=1015×100=66.67%

So, the Relative Percent Difference is 66.67%.

Example Calculation 2

Let's assume the following values:

Step 1: Calculate the relative percent difference:

RPD=|4530|(45+302)×100=1537.5×100=40%

So, the Relative Percent Difference is 40%.
