Jericho asked me to post a link to my spreadsheet here. I have quoted my original post below and the original thread can be found here
I started getting interested in finances back in high school. Part due to my next door neighbor (he lent me his copy of "Rich Dad, Poor Dad"), and partly because I saw where my parents finances were getting them and decided I didn't want that to happen to myself. I have been working on an excel sheet for maybe a year now. Originally, it was just for my own use, but it became more complex as time went on. A few of my friends started to express interest in using the spreadsheet also. So after many hours (many more than I should probably have commited) more I finally finished it. I have been following GRS for probably more than a year now and figured that the GRS readers might enjoy using it also. So here I am!
