Let me chime in here a bit...since we're kind of talking about Compounding...I recently read a news story about the Power of Compounding: How time can turn $3,000 into $50 million" http://www.marketwatch.com/story/how-time-can-turn-3000-into-50-million-2015-12-02 (the story basically talks about a hypothetical 12% compounded annually over a lifetime or two. -- nothing taken out or added in...just compounding and compounding on top of each other) ...and that's Investing mind you. -- if a Trader can generate that in a much shorter time frame, and spin those revolutions...it will be amplified.
Not everyone pays taxes on foreign income and many places allow you to only pay once you withdraw your profits, that is you'd only be paying for the amount you use for living expenses. Living expenses also vary a lot and can be minimized to very little.
Before you break your head on "how much money can I make" you should break your head on what you make in reality. I never had the problem that I read here: you should make enough to life from it. What if you have a losing day or week? Can you make 3%... The reason why is very simple: I started to trade in combination with a full time job. When profits became big enough and consistent I started to trade more and work less (part-time) and at the end I quite my job and became fulltime trader. I never had the problem about being able to live from my trading profits because I changed systematically in different steps from one side to the other side. I gave up my job when I was sure that I could survive without any problem. The next step was leaving my country. As profits became "relevant" I moved because now I pay 7 times less taxes on my income. Staying in my native country was not an option, or at least a very expensive one.
Since the length is not specified clearly, let assume 10, 20, ... 10 years later === 9317.54462503263 20 years later === 28938.8792798248 30 years later === 89879.7663627334 40 years later === 279152.911324092 50 years later === 867006.569490001 60 years later === 2692790.80047318 70 years later === 8363399.4830954 80 years later === 25975449.3002388 90 years later === 80675802.6700824 by 3000*1.12^(i*10). After 80 years, it is exactly 25975449=25975K=26M. Therefore, it will takes between 80 and 90 years, before seed of 3K becomes 50M. It is NOT surprising. ************************************************ Furthermore, if you can add 2% more (annual 14% compounded) every year, then initial 3K seed becomes 10 years later === 11121.6639423557 20 years later === 41230.4696155649 30 years later === 152850.47574994 40 years later === 566650.541573341 50 years later === 2100698.96537752 60 years later === 7787755.97899436 70 years later === 28870934.9544822 80 years later === 107030945.421787 90 years later === 396787402.13791 100 years later === 1470978714.37939 by 3000*1.14^(i*10) ************************************************** After 90 years, the two ratio (12% and 14%) is 396787402.13791/80675802.6700824 = 4.918295= 5 times difference In summary, save 3K early, to expect several Million in the future as most millionaire does.
I was asking as your compounding was over 90 years. Now, gene wise, I 'll certainly beat you to that.
Here is more realistic result, since small say 50 years more expected.
