There are many posts about it and soon a staff member will be directing you to one but here's what I know.
Residency: Usually around 42,000 dollars per year, depends on the program though. It increases by 1000-2000 dollars every year.
Fellowship: your basically depends on your postgraduate year, so if you have done three years of residency, your fellowship's first year is your PGY4, and the pay is a little more than that in residency, say around 55000 dollars per year, and increases by 1000-2000 every year.
After fellowship, I hear its around 150,000-300,000 dollars per year and maybe even more, depending on your specialty, practice, state etc.
