I've seen other posts regarding the total number of domains in your portfolio, total sales, etc.; however, I have not seen one regarding what people's renewal fees are per year for their portfolio. Assuming you need to renew every domain in your portfolio, what would be your TOTAL renewal cost? Keep in mind the different extensions you have and adjust your calculations accordingly. EDIT: If you are looking for an easy tool to break down your portfolio per extension, go to http://www.midano.com/domainInventory.asp and paste in your portfolio. You will get a break down of all of your domains based on extension and you can calculate accordingly.
