IN Retirement calculator
How long will your money last? Most calculators give estimates on how much to save. For us boomers who are already in retirement (forced through job deletion or by choice) it is too late for saving.
Free calculator (article on USA today) at RowePrice to determine how your current expense or expected expenses vs your savings, investments, how long to expect your money to hold out. This of course is barring tragic events.
PS - if it happens to say you can spend more, as it did for us, doesn't mean you HAVE to!!! LOL
