Frequently Asked Questions
What counts as contractor overhead?
Everything not chargeable to a specific job: office rent, admin wages, owner salary, insurance policies, vehicles, fuel, software, marketing, tools, and estimating time on jobs you did not win.
How do I allocate overhead to individual jobs?
Divide annual overhead by projected annual direct-cost or labor-hour volume to get an overhead rate, then apply it to each estimate. A $150k overhead across 10,000 crew hours = $15/hour on every quoted hour.
What is a typical overhead percentage for contractors?
Usually 15–25% of revenue, higher for design-heavy or low-volume shops. Knowing your real number is the difference between quoting profit and quoting hope.
