10 million dollars after taxes so I'm guessing the actual amount is higher, possibly around 15 million dollars. on top of that 300k a year will be subjected to taxation, you will end up with 188k a year, not quite the 300k. you would need around 450k a year and after taxes, you will end up with 300k. to be able to produce that much you'd need about 15 million dollars after taxes. so in reality you'd need about 20 million dollars.

20 million dollars, would generate 300k after taxes if invested in bonds. from the 20 million, you'd end up with 15 or 14 million dollars after paying taxes.

so 20 million dollars is what one would need to target for.

however, note that you'd need to live in a large mansion that's already paid for and maintenance and expenses, property taxations being paid, I'd put away 30~50k for upkeep. You will probably have two kids on average so it will be another 100,000 to support them.

21 million, seems to be the true 'FU' money. After that leave off 400,000 after tax a year in money.

21 million is a staggering figure for someone starting out. I don't even know if I will get to one million.
