Talk:Rate of return on investment

Unclear Article
1) This calculation is an ex poste calculation of actual returns realized, not the returns expected ex ante using NPV or IRR method  What? I schooled as a physicist and I don't know these terms. Please, MAKE YOUR INTROS READABLE! Maury

2) With due respect to the authors, I think this information is rather unclear to the average reader. SueHay 02:49, 20 January 2007 (UTC)

3) I agree, with the exception of the simple formulas, I find the article difficult to understand.  Obviously parts of it was written by high brow mathematicians who think that we all have the comprehension of astro physicists. Although 12:09, 20 January 2007 (UTC)

4) I had no problem to read the article (but I have an MBA with finance as major... I think the best idea would be to use the explanation that appear in any basic textbook, then also to quote the source.

I looked at the example, also in NPV, they are not good examples. IF the author wants I will be happy to supply clearer examples of my own (I was a teacher of financial modeling for many years in TAU) YoavD 17:42, 20 January 2007 (UTC)

Author's response
Obviously I wrote this trying to help people keep track of their investments. It serves no purpose if no one can understand it. I have re-written it. Please leave SPECIFIC comments. Does putting things in brackets to offer another explaination help or hinder? Did not the Excel file that shows it in practice not make it clear? Or do few people know how to use spreadsheets? There is no "that appears in any basic textbook" that accomplishes what you must do to adjust for the effects of added savings and withdrawals - that is why it gets complicated.
