I'm trying to help my Dad with some investment choices. 70% of his money is in taxable accounts, so we need to have a spreadsheet that looks at the gains per year / then subtracts X % taxes so that the following year returns are calculated on the proper basis. I can tediously do this cell by cell of course, but there HAS to be a formula or sample sheet out there with this all set up...
Any help or links would be appreciated!
