Editing Talk:Net present value (section)

== Is there something wrong with this calculation? ==


A while ago I had posted a link to the finance wonk's version of net present value calculation at http://finance wonk.blogspot.com/2006/05/present-value-analysis-fundamentals.html

(Remove the space in the first word in the address to use the link, the blacklist kills it here too!)

Recently it was removed and I was notified the site had been blacklisted?

Did I do something wrong? Or is something wrong with the analysis on the destination site?

Looking at the finance wonk page (I haven't reread it in detail) it still looks like a neat runthrough and I like the plots, they do a lot more for me than the equations on the current wikipedia page. Especially the third and fourth ones.

I also like the discussion of how to do NPV in excel, although I see someone has found a possibly better site for that and added it to external links (cool!).

It still looks like the plots contribute a lot, I would add them into the Wikipedia write up except that it would violate copyright since that site obviously owns them (or so I assume). 

I read Wikipedia's policy on external links and the link would seem to qualify on the basis of the cool plots alone, and financewonk doesn't ACTUALLY show up on the blacklist (http://meta.wikimedia.org/wiki/Spam_blacklist)  so I can't even tell if there's an overall site problem or what.

Mostly I'm intrigued by the process and hoping the person who did the blacklisting/removal could comment. Is it because the blogspot page has google ads on it? There is hardly any of it and it's kind of out of the way, but I could see if that were a policy.

Full disclosure -- I do know the guy who writes that page. I consider a (small) handful of his work link-worthy, most of it being rather more specific and of limited application.
