re: 401(k)

OP you are likely in the top 10% of contributors. Asking how well you are doing really doesn't make sense unless you say how much you earn and how much you expect to withdraw/ use in retirement.

But if you don't add another penny, and assuming a 7% increase a year where your money doubles then at 60 you'd have $1.5 mil without contributing any more. a 4% withdraw of that would be $60k a year.
