Production rates from ISSA are averages. Verify your own rate on comparable accounts before using any rate in a bid.
The default loaded rate of $21.09 uses BLS May 2024 national median + 22% burden. Substitute your actual metro wage.
Overhead + margin markup should reflect your total fixed overhead as a percentage of direct labor, not a target margin alone.
Before submitting a bid, verify current local wage rates from BLS OEWS for your metro area.
