What a lot of people aren't addressing is what they really want to DO in their retirement. Start considering that before worrying about how much money you think you will need!
Retirement isn't about living and spending like you do "now", there's lots of stuff you don't "need" when you are 65+, should you live that long.
If all you want to do is play the odd game of golf, take a Cruise every so often, buy a new car every few years until your eyesight fails and you can no longer drive, you really don't "need" $60,000 plus a year.
Will you dine out and entertain on a weekly basis, or just take walks along the local beach?
How many new clothes and shoes, etc do you think you will need? Not much, believe me.
Will you really need to buy all that new furniture?
Retirement is, usually, a time to RELAX and enjoy the grandchildren, if you have any. Have friends over for a BBQ, take an annual holiday "somewhere", have FUN and hang about Forums such as this.
