This is my first income question for every client. It's elemental to your SOAP note and a critical decision factor in identifying the right career path from your Career Diagnosis™.
Just like medicine, different businesses and specializations have different income levels.
Unlike medicine, these can vary widely based on the specific companies. Medical incomes are based generally on a national average or standard. IM's in Georgia make about the same as those in Oregon. The hiring competition for physicians is generally seen as a nationally focus activity. That may or may not be the same in the nonclinical field you choose.
Outside medicine, you could be Executive Director of a foundation and make $500k annually or with another foundation you might find $50k their top salary.
So, don't pre-judge expectations by industry. First decide what you want to be doing, and then seek specific businesses or organizations that will meet your income expectations. Here's a tip, at https://guidestar.org you can find income and salary information for nearly every nonprofit organization in the U.S.
