Most disc jockeys make between $5,000 and $40,000. The exact amount depends on the type of disc jockey, the disc jockeys popularity, the location of the disc jockey, type of payment, and whether the disc jockey is a hobbyist.
For instance, a mobile disc jockey may be paid $800 for one performance, but they may only perform twice a month. Meanwhile, a club disc jockey may be paid $10/hour but with a full time position, the club disc jockey would be making just as much as a mobile disc jockey without including tips. Also take into account that a mobile disc jockey has expenses that a club disc jockey doesn't and you'll see that the club disc jockey in my example actually make more that the mobile disc jockey.
