My wife and I retired 6 years ago at age 64 so we have some experience with this. It depends on a few things. Overall health, retirement plans for traveling, desire to still eat at restaurants on a regular basis, family responsibilities, etc. everyone has different wants and needs. Figure out what you spend per month now, how much you want to spend for entertainment, healthcare cost, etc. then decide how much income you need above social security and any other steady income you have, like a pension for example. Then decide how much additional savings you need to draw from. Just make a spread sheet and put it all down in black and white. Don’t forget that you will still need a new vehicle occasionally and nursing homes are currently running around $10,000 per month. To be fair to your children, you need to plan to live to 100, even though most people don’t make it. You don’t want to become a burden to them. With all of that being said, I expect that you will decide that you are going to need $2-3 mil in most cases. Your going to want to be a bit more conservative with investing to protect your available cash stream against the unexpected, like Covid or a 9-11 type of event crashing the market for a few years. If you do your homework and plan correctly it is a wonderful reward for all of your years in the workplace. We travel, go on western hunting trips, and pretty much do whatever we want too only because we planned correctly. I know other retired people who are restricted from doing anything other than going to Kroger and complaining about the price of potato salad. DETAILED PLANNING IS THE KEY!
