How to calculate Defect density in Agile

[Ananth Chivukula]

I have a Question on what's the formula to calculate defect density

for example-we have a 2 week sprint  with velocity 40 story points , say we found 2 Regression Issues ,  Do we also account for intrasprint bugs created for each story as part of it just defects only?

I m assuming it's calculated ==no of  defects/ Total Story Points ==2/40==5%

I think this depends entirely on what your calculation for "defect density" is.
