The data I find states that for those 65ish, the median retirement nest egg is $200k. That, to me, perfectly illustrates how inadequate the retirement policies in our country are.
Very few companies offer a defined benefit pension, presently. Most have moved to a match on something like 401k accounts. I was very fortunate to get hired by big oil. They offered a defined pension, and a savings plan, with a very generous match. They allowed you to take the retirement benefit as a lump sum, which is what I chose. They also offered company subsidized retiree health insurance. So, I am not a typical retiree.
My best advice to those working with a 401k with a match is to contribute enough to get the match. Then fund a Roth IRA to the extent you can. Then take as much risk in the market that lets you sleep at night.
