If you're assuming withdrawing at a safe withdrawal rate you're assuming you're not compounding. You're assuming a safe withdrawal rate from principal/dividends/interest that will, on average, leave the principal constant. Of course, if you're older and are not looking to pass down money you may be fine with drawing down principal to some degree.

So, yes, $2m should probably be modeled at about $80K income per year before taxes without touching principal but without building savings.

(May be somewhat higher with higher interest rates/inflation.)

I said an annuity. An annuity would draw the principal down as well, and you generally make a drawdown assumption that leaves you with some safe margin for extended life and maybe some inheritance.

If you model it as a lifetime annuity with inflation adjustment you are looking at more like 50k/year income at the outset were you to buy today.

My understanding is that annuities provide in general a worse return than the so called 4% rule on average.
