A 4 or even 3 percent withdrawal rate is more likely to be sustainable. Those are also rates I see suggested more commonly on retirement planning sites.
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.)
My understanding is that annuities provide in general a worse return than the so called 4% rule on average.
There's a whole active debate around exactly what numbers are sufficiently safe over what time horizons and what portfolio mixes. For a fun long read, see ERN's series on safe withdrawal rates https://earlyretirementnow.com/safe-withdrawal-rate-series/
The only real challenge is a portfolio mix and withdrawal strategy that minimizes the damage from withdrawing during downturns. That's where the 4% rule becomes relevant.
I bet I'll see 5% within next 2 months. Obviously interest rate changes drastically over time.
5% interest hasn’t been avail from a bank in a couple of decades, and the fact that we’re close to it again doesn’t mean it will stay that way…
You just can’t get a guaranteed risk-free return of that range indefinitely, which is why a lot of people shoot for 3-4% when they don’t have more capital to invest in riskier but higher return investments.
