Median topped $40k in 2022.
The (just under) $100k is pre-tax.
You won't get much social security when you hit "retirement age" if you retire after only 20 years of working at that level of income, so you'll need more savings at that age than others do.
$100k/yr is a 5% withdrawal rate on $2 million, which might be a "safe" rate at normal retirement age (debatable) but is risky as hell if you start doing it at 45 and don't plan to die in your 60s.
If you've been saving that aggressively (as cash/investments), you won't own your own house, or at least, you definitely won't be anywhere near paying it off. That significantly raises your costs in retirement.
You have significant risk from healthcare costs until you hit medicare age (and even then...). You're probably looking at $5k-10k a year in premiums (individual) at age 45+, and still five figures of annual risk exposure despite already paying that much.
Retiring on $2m at 45 would be very likely to end in failure, even as an individual supporting only yourself.
