Need help with formulas calculating cost basis on shares
Let's try the link again. Here. But if that doesn't work again, you can just enter "calculating cost basis for stock" in Google and find it directly.
And you'll need to help me help you by putting on-line a copy of whatever records you've been keeping in Excel on at least one stock where you've done a fair amount of buying, selling, getting and reinvesting dividends. It shouldn't be hard to get that kind of history from your broker. But I would hope you have at least some knowledge of how to store the records of the transactions. You don't need to do any calculations. Just date, stock symbol, transaction description, quantity, price (per share).... that kind of stuff.
Put a spreadsheet on OneDrive or GoogleDrive with a link pasted here that grants access.
