I'm a big nerd, the first thing I thought when dreaming of winning this lottery was, "Imagine the shave den/ bathroom you could build with that kind of money"
The lump sum option would result in a payout of $327,400,000. From that you have to pay both federal and state (depending on where you live) income tax which will likely be in the 45% range, for $147,330,000 in tax, resulting in a net payout of around -- $180,070,000.
Now, 180 million is a lot of money, but it is not 500 million .......
