Yes, kind of a mess. I thought, well I'm not going to post any longer in this thread. Then after reading the last post stating that even JG mis-interpreted the question I'm back.
First, I would not like anyone of you to take offense or think I'm rude in any way. I'm just going to be blunt to let you grasp that at least there are other ways to look at things.
I'm not interested in the way things are defined in a simulator, to get a simulated projection of a possible outcome based either on historical (unfavorable) or monte-carlo (more favorable) runs with whatever likelihood..
I'm interest in real life. My net worth is (assets - liabilities). DOT.
Then I'm not necessarily deriving income from work, but most comes from commercial rental real estate. Even though I would burn it all, as the RE investment in itself follows inflation, I'm not sure one can consider that I've withdrawn anything from my capital base (my RE cap base remains constant as it is inflation indexed thanks to the rents indexed on CPI or kind of INSEE index). Not only that, but I do not burn it all and more than 40% goes into ADDING (not withdrawing) to my retirement portfolio from which I expect big capital gains and no income. This is to give a small snapshot (simplifying a lot as I trade aside, etc.)
Therefore, in my real life, at year end, I look at my net worth (assets - liabilities) and either it has increased or decreased (whatever I make a living with). I have withdrawn 0% from my investment portfolio (as I do not consider this class of asset as capable of generating income - look @ the paper "Make retirement income last a life-time" and even 1% of portfolio going broke @ 30 yrs is unsatisfactory so 30% @ WR 4,5% broke @ 30 yrs based on historical data is alarming), I live on RE, keep adding to the retirement portfolio (looking for big cap gains @ 20 yrs) and keep trading (looking for cap gains @ shorter time scales).
That's REAL life not the simulator. My net worth (NW) increases year after year and therefore (working or not) I think that my withdrawal rate is negative.
Again not being rude. I understand perfectly that even my NW having increased one might consider simply that I have withdrawn less than the return of the assets. But mixing classes of assets, putting RE in the picture, taxes, etc.. gives a more complex picture and I'm back to basics (assets - liabilities).
Not claiming to have any thruth. Just stating that I have a different perspective on the subject.
Kind regards to all contributors of goodwill (as I am)
