An exorbitant price, fee, or amount of money is much higher than it should be — so high it feels unfair. We use it when we complain about rent, tickets, interest, or a bill. It is a little formal; friends might just say “way too expensive.” Though actually, the old picture in the word is “off the track”: the number has left the usual path. We almost always put it in front of money words (an exorbitant fee), not in front of a person.
