I can't give this one away for free, though, as I didn't create it. Plus it's way better than anything I could do.

Product Review: ExcelGeek's Freedom Account Spreadsheet
I should also add that Jesse at YouNeedaBudget.com has a sweet spreadsheet that accomplishes Freedom Account tasks also ... albeit in a different manner, and with some bigger budgeting features thrown in. (Disclosure: If you buy his $20 spreadsheet via my links, IYM gets $5.)
And no, I don't have any intentions of beginning to charge for the spreadsheets that I already make available for nothing more than the price of a click. They're not nearly pretty enough for me to slap price tags on 'em. :)
