The following is taken from a FaceBook posting from Troy Wilcox (https://wilcoxsound.com/) in answer to someone wanting to know how to calculate the hourly rate when quoting a daily rate. I have not officially asked Troy if I could copy his posting, but I assume that since it was a public posting -- he will not object. Besides, I have known Troy since the eighties!!! We were all a part of Skyline Productions (sound rentals, sales, crew) and then its successor Wilcox Sound. In those days, Troy was a Utility Sound Technician and Boom Operator, working episodic TV and commercials.
This is a break down on hourly rates
Hourly rate break down based on daily rates of $200-$650
Commercials & Music Videos
Hope it’s helpful if so give it a like.
