How much does Dave Ramsey make a year?

How much does Dave Ramsey make a year?
so we are trying to guess what Dave Ramsey makes annually
based on his house value
using his advice and the mortgage calculator on his site
my guess is millions
if we price the house at 7.5 mil
paid in cash
or a 15 yr fixed rate, lol
and a 15 year fixed rate mortgage would be 50,000 / month
and if he is conservative, lets say that 50k is like a 6th of his annual
that would put him about at 3mil / year
haha
exactly
compare to Yu Darvish who will make 189 mil by 2014 from Rangers
