A lot of it depends on where you go(the more popular locations pay less), the type of practice(solo, group, multi specialty, VA, Kaiser type network, academic), and what you do(consults, inpt, outpt, procedures incl EMG, injections, etc.).
From what I have HEARD (so it's heresay - I did not see anyone's actual pay check or contract)
Most academic positions start 90-130K in big cities like NYC, Chicago, etc.(I heard as little ask 90K for "prestige" like Columbia/Cornell) For private practice, I've heard btwn 140-180K for general rehab straight out of residency. That 180K is for northern california where cost of living is high and it's not as saturated as southern california. If you do a fellowship starting ranges btwn 160-200K - with obviously a lot more as you get further into practice. Most practices lose money on you the first couple years - I've heard it takes 2-3 yrs for a practice to "break even" on you - so after that, you do better. Some of it depends on how efficient you are (productivity bonus) and whether you are willing to do certain procedures, consults, etc. And like the earlier post said, also depends on how much work you are willing to do. I shadowed a private practice attending in NJ making 400-500K - without fellowship - he had a private outpatient clinic, a nice inpatient unit of about 10-12 beds w a PA doing most of the day to day work, consulted at 2 different nursing homes/subacute rehabs including most Saturdays, and did 1/2 day EMGs per week. He was pretty much a solo practice although he shared his clinic space with his wife who was also a physician. So it really depends on your business skills. Also, your starting salary is not necessarily indicative of the long term earnings. Some practices will lure you in with a high starting salary then trap you with very little opportunities for future partnership, etc. Need to factor in things like benefits, tuition assistance for kids, loan repayment, mortgage help, pension plan, etc. I do think you can have a relatively cush lifestyle and still make over 200K in PM&R 3-5 yrs into practice.
that's my 2cents.
