Subject: Re: Safe Retirement Withdrawal Rate for 2026
it is 4% (ish, maybe 4.x%) for this allocation for a 30 year horizon. PhD economist Karsten Jaske (BigERN, as he's known online, being 6'7" and ERN = Early Retire Now) did a 50+ part treatment on his website of the crazily nitty gritty details of SWRs for longer horizons.

I'll save everyone the read (I made it through about 1/4 of his entries). If you want a 40-50+ year horizon, 3.25% is safe for like 90something percent survivability across Monte Carlo simulations.

Dr. Jaske's series is here - https://earlyretirementnow.com... - and as he pulled off FIRE in his early 40s, he definitely has skin in the game.
