Just catching up on this thread and all I can say is wow! We finally have a sighting of that previously mythical beast, the person who thought you could just blindly follow the 4% rule :) Congratulations @FIREin2018, I'm glad it's working out well for you.
Wait, people discuss the 4% rule here but don't follow it?!?
And, thx. Like i said above, i got lucky. I had no clue about SORR when i FiRED in 2018.
My absolute steel belief that the 4% rule working out in the long run (30yrs) kept me calm and cool during Covid whereas many around me was popping Xanax like candy as the stock market sank lower and lower
The 4% rule is modeled off of a lot of things that need to understood in order to use it effectively, as has already been said, it's a starting point.
First, it's very, very good math based on made up numbers, meanings it's entirely based on your own estimate of how much you will spend decades down the line. That's not really realistic. Also, some people add huge padding to their budgets, while others have really tight budgets.
Second, it assumes that the person will spend *exactly* the same amount every single year plus estimated inflation, year over year, with no change, regardless of what happens in the markets or their personal lives. This makes no sense.
The 4% rule is very good for projecting how your wealth will hold up to market fluctuations, but is absolutely useless for anticipating changes in your lifestyle and spending needs.
So person A could have 500K saved and project an annual spend of 17.5K, or 3.5% withdrawal rate. His spending could be based on his last 7 years of spending because he lives in a rented house-share where he gets reduced rent because he's really good at DIY, with 6 other guys, doesn't own a car, cooks all his food from scratch, and vacations at his parents' cottage. He left work because he was a laborer and is starting to have serious back pain.
Person B could have 3M saved and project and annual spend of 128K, or 4.25% withdrawal rate, but she also has 1.5M equity in her home that she doesn't intend to sell, so she don't use it to calculate her withdrawal rate. She also has massive insurance policies for life/disability/etc. Lets say about half of her annual budget is for international travel, so her spending could easily be cut in half, or diverted elsewhere. She left her career as a dermatologist, but keeps her license and could go back to work part time at any time.
According to the 4% rule, person A has less risk and is less likely to run out of money over 30 years, but that's because the models can't account for individual factors that can and do impact spending, or how realistic someone's estimate spend is over decades, or that person A is a single medical emergency away from total financial collapse, while person B has so much more security and ability to adapt to whatever comes.
That's why the 4% rule is a starting point, because it's only an indicator of how the markets have behaved over the past many decades. It doesn't guarantee anything about future market returns and it predicts absolutely nothing about the many, many factors that could alter your spending over time.
So it's not that no one follows it, it's that virtually no one here considers is a
complete strategy for retiring and managing risk.
There are folks who retire on exactly 4% but that's usually because they've done full risk analysis and have figured out their own hedges for their own personal risks.
