Let's say you come up with $1million as nice round number. Again, this could as low as $500K in some countries and just for a very modest lifestyle up to $5 million for US, with many years to live, and with a nice lifestyle.
Daym you need $5m to live in the US?
Wellllll...
The traditional financial advisor .. um ... advice is to plan on withdrawing 4% annually.
So 4% of $5M is $200K. Is that enough? Before taxes? It's an individual target.
Note that the 4% assumes normal retirement age and life expectancy. If retiring early or planning on living to 268 years of age, you might wanna reduce the percentage for calculation purposes.
I might have different assumptions about the traditional 4%, which I thought was meant to be a perpetually sustainable withdrawal rate because it is presumed that you are going to be able to average at least 4% per year returns (some years higher and some years lower). So, 4% should even work for someone who lives to 268 years old.
Well, there are a lot of unspoken assumptions that go into the 4% figure. So, there are a lot of ways to skin this cat.
As for me, I value dollar-value a whole lot less than I value purchasing power. In order to be perpetual in terms of purchasing power, your return needs to outrun inflation by a factor of 4%. Which is a whole lot more than simple 4% per annum in dollar terms.
I would think that 'financial advisors' -- CFPs and the like -- have a fiduciary duty to forecast typical life expectancies into their recommendations. Accordingly, I believe the publicly broadcast 4% figure to factor in typical (e.g. 65) retirement, depleting all principal exactly by the day of expected death. Otherwise, their client would be 'leaving money on the table'. Literally. Plus, that is roughly the explicit disclaimer I have commonly heard attached to such advice.
But hey - it's just a wet finger held aloft in the wind. What is more important than the 4% figure is going through the exercise of deriving it, so you can tailor a plan to your own situation.
