Some quick math shows that if the $1T goal is reached, assuming taxpayer savings remain proportional to the numbers given now, the average taxpayer will save $6700.

(Edit: Oops, the goal is actually $2T, so average savings of $13,400, I guess.)

Of course, that won't be distributed evenly, so I suspect most people will see savings of $1K to $2K at most in a best-case scenario.
