If your goal is to enjoy your money and use it to increase your happiness (and that of others) in life, then I would suggest that a withdrawal rate that is very likely to leave you with 10 times as much as you had on the eve of retirement is probably the wrong approach.
Remember that if the odds of you running out of money in 30 years are 10%, and the odds of you actually living 30 more years are 10%, then your actual risk is 1%. That’s lower than the risk of an experienced mountaineer dying on Mt. Everest.
Everybody I know in real life retirement keeps track of how they’re doing. If their returns are poor, they cut back, tighten their belt, cancel a few vacations, give less to charity, give less to heirs and make it work.
Retirement spending follows a curve where it is highest the first few years of retirement when lots of purchases are made and traveling is done and then gradually decreases until just before death, when it ramps up dramatically with medical and/or long-term care costs.
Well, 75-80% certainty over a 25-30 year retirement for a portfolio of 50-75% stocks corresponds to an SWR in the 5-6% range. That’s 25-50% more money to spend each year in retirement. That’s hardly insignificant.
