To help address that challenge, we'd like to share a simple Billing Rate Calculator that was designed specifically about our industry. It has very basic functionality weighing in Overtime, so it may not be very accurate if you do a considerable amount - but this calculator may open your eyes to opportunities you're missing, as well as help you identify where your books are bleeding money and you aren't aware of it.
If you're unsettled what your billing rate should be, you're not alone. I meet a number of stagehands and producers that still seem squeamish when discussing their rates. Of course we want to get the best rate we can, but it's also important that whatever your rate represents a value equal to the value of what you bring to the table.
