Overhead Allocation Calculator
Allocate office overhead before final bid review.
Key takeaway
- A construction overhead allocation calculator estimates how annual indirect costs can be spread across billable hours, crews, or project pricing. Contractors use it to check whether bids and change orders include enough overhead allowance, while confirming final treatment with accounting and company pricing policy.
- Use the calculated overhead rate as an estimating checkpoint, then reconcile it with job-cost reports, accounting guidance, and company pricing policy.
- The calculator uses contractor-entered overhead and hour assumptions. It does not replace accounting policy or financial review.
