One of the biggest factors in your DJ costs will be the type of party you are hosting. As you might expect, wedding DJs cost more than a DJ for a graduation party or anniversary. But did you know that DJs for coming-of-age parties often cost more than wedding DJs? Thumbtack research, culled from tens of thousands of Thumbtack quotes, has shown that bar and bat mitzvah DJ services can cost more than wedding DJ services. In fact, in 2015, bar mitzvah DJs were 32 percent more expensive than wedding DJs and 93 percent more expensive than the average birthday party. This is because the DJs are working double-time, simultaneously serving as MC, DJ, crowd control, joke master, and dance instructor all rolled into one. If you’ve ever tried entertaining a banquet hall full of tweens, you will understand.
