Do you have a pension, 401(k), any other income?
In general a decent gauge of what you can expect your portfolio to provide as retirement is about 4% of your total portfolio. Some planners do try to be more progressive with that number, leading that percentage higher sometimes, but in general these are the general things to consider and probably a decent place to start.
Anthony, Depends on the following; 1] your pension/Social Security payout/ 2] your accumulated assets at that time 3] How long you expect to live. 4] Do you have a desire to leave assets to your hiers. You really need to consult with a "Financial Advisor " to get a good idea. Good Luck Dan
