You messed up the numbers in the sense that it's $11 billion over 5 years, not annually. So you're over by a factor of 5.
$9/home/month or $110/home/year for 5 years is even more manageable, though!
Edit: I see now where militiaman21 requested that the title be updated to "over 5 years" per new information. When I posted my numbers, the title said annually. I thought maybe I had missed something in the text.
