What is the highest amount a doctor can earn?

There is absolutely no limit. The average salary of a doctor can range from $150,000 for a general doctor, $163,000 for a psychiatrist and $255,000 for a general surgeon. Regular doctors are not likely to earn more than this, but entrepreneurs can earn millions. This means doctors who, for example, instead of treating patients, invent a new drug or invent something that can be used by other doctors. But only a very small number of doctors do this.
