Put it in several index funds and then live off 4% a year? Which in this case is 20 million. Or 10 million if 500M was the pre-tax amount.

I’ve always thought that the key purchases are long-term, so only investing 75% allows you to get the big purchases that I’d make (house, families mortgages, e-car, etc) then the up keep is paid for by the interest and dividends, allowing me leftover each year to give to various charities over my lifetime
