It hugely depends where the teacher is teaching...high school or college team, studio, or the big wigs choreographing for shows like so you think you can dance
on average studios tend to start teachers around $15 dollars an hour, but as they gain experience and a good reputation they can cost over +$100 per hour. On average they get paid between $15-$50 per hour
high school and college coaches really only get a few thousand in one season which can be a lump sum at the end of the season or a small monthly payment. I was receiving 150 a month as an assistant coach. Head coaches only make 100 or 200 more per month. All in all you rarely hear about them earning more than $3000 for a season.
Twitch from So you think you can dance costs over $600 a day!!
