I have been retired over 7 years and have yet to collect Social Security (not old enough). I am living very well and have managed to maintain a constant draw that has not changed in these years. I do have some real world experience here.
First, I agree with the advice to go see a financial advisor. But find one you feel secure with. Interview several before deciding on just one. And if one of them tells you that they can get you more than 6% a year with no problem, RUN! You might get more but that is not a given.
Now, to the meat.
Figure a 6% return on your money right now. DO NOT put all your money into stocks. Diversify!!!! And most importantly, do not draw the full 6% return. Remember that inflation continues after you retire. So you want to grow your nest egg. Put at least two percent back into the nest egg for growth.
Most planners are going to suggest that you have enough saving that will return 80% of your best year's income. This is great if you can do it but really not necessary. Say you are making 100,000 dollars a year. But after taxes, social security, savings, etc, you only get home with $65,000. This is the amount you are really living on. So you have already reduced the amount of saving you need to have. Next, your taxable income drops because your income drops. No social security to pay. More savings. And, not working saves meals out, wear and tear on cars, reduced need for work clothes, etc, More savings.
And, if you have your home paid off, cars paid off, charge cards paid off, and are basically your own person, you will live very well.
The key to retirement is that you MUST be a responsible adult when it comes to your savings. DO NOT pull out cash for a new boat, or car, or vacation. Save for these things and then pay cash. And most important, do not use any of your savings to help out the kids, relatives or friends. You are no longer working and cannot replace the money you give away.
Finally, draw social security as early as you can. Most calculations show that it take from 10 to 12 years to make up the difference in the amount of money you get from uncle Sam if you wait until 65 to draw (this assumes that you can retire before 65).
Bottom line, it takes less money to live well than most people realize.
And by the way, I still buy guns, travel, eat out, and basically enjoy life on the money I am drawing.
Go talk to the financial planner but do your own math also.
