I have been crunching the numbers since I made the decision to leave our IRAs invested in the market throughout this painful crash. We were 100% stocks, and overweight in foreign stocks. Still are but they are all down. We will need to save at our current rate for four years to make up the losses we've incurred since January 08. That assumes what is invested stays flat for the next four years. It would be nice to save more but I'm not sure that is going to happen.
In good news, I am still pretty healthy and can go dig ditches as needed in order to pay the bills.
I'm going to open up a Roth IRA this year as future tax burden is likely to be higher than present day. I'll probably put everything into agricultural commodity index funds and oil if it stays low.
