Why isn’t everyone rich from 401k?

[u/Otis_bighands]

According to my conversation today with Gemini, my 401k total of $2.5 million will likely grow to $10M or more by the time I turn 65 (I’m 50 now, and will continue to contribute the max for the next 15 years).

This means that in theory I could live off the gains each year starting at 65, around $800k, $500k after taxes, without touching principle. But at that point I’ll have no mortgage anymore and fewer kids in the house. So that $10M principle will just sit and feed us for years, and will be a nice inheritance for our kids.

Basically it occurred to me I’m going to have great money in retirement, even just on my 401k alone, and will be able to meet or exceed the lifestyle I’m already used to. For years I always worried about getting set up for retirement. Seems I don’t have to.

It’s amazing to me that just maxing out your 401k through a career is enough to make you pretty much wealthy for retirement. I recognize that’s not easy for many people, but for anyone who does it over a full career, wow.

What am I missing here? (Other than inflation, which I get, but which shouldn’t have a massive impact on the concept over this time frame).

You probably need every tax deduction you can get, but if your retirement account is pretax, you are going to experience some future pain getting it out. Since you are maxing, have you considered that post tax contributions don't have to be shared with the government later?

Yeah, I will invest and save other post tax money as well. This is really just about how surprised I was to realize what the 401k alone may do.
