Essentially, you charge what you're worth. In our area, $60/hour/person is on the low end, but hopefully you can swing upward by making your service more valuable and by being more efficient in contract work. If you're starting out, here are a couple rules of thumb. Your labor cost is roughly double the hourly rate. Your labor cost is roughly half your total cost.
If you're charging $90/hour/two-person crew, your average wage should be:
$90 divided by 2 (two people) = $45/person
$45 divided by 2 (labor as half) = $22.50/hour/person total labor cost
$22.50 divided by 2 (wage as half of labor) = $11.25 average wage for crew
If you're paying people more than that, obviously your hourly rate should go up accordingly. Or work backwards from what you can charge to determine what you can pay. Or go to
