$93,917 for 2015. I was lucky enough to be born with gifts that make me good at writing code. I trade that coding ability for money. I invest that money in the S&amp;P 500 (ticker VOO). I&#x27;ve been doing this for decades and have invested about $1,173,971 to date. The trailing 10 year return is about 8% per year. So let&#x27;s call it $93,917. $93,917 of passive income.
