I looked in urban/suburban (not LA/NYC, but places like Dallas/Fort Worth) and rural areas. Starting offers with small, private groups were $200-300k/year (the vast majority were ≤$240k) + production (variable, but usually 20-30% after 2.5-3x base salary), usually with a ~$20k signing bonus. Parternship tracks were 1-3 years (most were 2). It was easy to see what partners were making and get an idea of what is your ceiling -- this number was often ~$650k, though the range was $500 to comfortably over $1M (and this did not include income from real estate, ASC, etc).
HMOs averaged $350k starting salary with perks like loan repayment and RVU bonuses. It was more difficult to get details on what others are or were making with RVU bonuses. Realistic ceiling seemed to be about $500k at most places, but lots of reasons to consider it, especially if you can utilize public service loan forgiveness or plan to stay until retirement.
I did not look at private equity, but I've heard that compared to private practices, they offer a higher starting salary, decent incentives, and a lower ceiling. I can see why people are tempted to sell to private equity, but I did not want to support it and hate it changing the landscape of our private business models.
I looked at one job in academics that offered $190k starting. I did not negotiate or look around. Most salaries are public information, so you can see what these positions pay.
It was easy to feel a bit disappointed by our relatively low starting salaries (compared to any other surgical sub-specialty), but it's very short term.
