I have seen post on this Website, where students have been offered 90 to 100K right out of school.
It is hard to look at averages, because there are so many OD's that work part time. I for one would trust the AOA stats more that any goverment stats. The goverment gets thier stats from taxes... and people always downplay what they make on thier taxes (especially if your self employed). AOA conducts private surveys, and people are more likely to be upfront and honest with the surveys.
People like to compare Pharamcy Saleries and Opto Saleries, but the fact of the matter is many ODs have much better working conditions as a Pharamacist. (who are sometimes forced to work 12 hour days, and lots of overtime due to shortages). Also, a pharamacist right out of school makes almost the exact same amount as an pharamacist who has been out of school for 20 years (at least in retail anyway). However, I guess this could be the same as for ODs as well.
I think your earning potential for an OD is much higher in the long run, especially if you invest or join a private practice.
