What is commonly used to determine a percentage for overhead in a bid?

Using historical data to determine a percentage for overhead in a bid is a common and effective practice. Historical data provides contractors with insights based on past projects, including the actual overhead costs incurred and their impact on overall budgets. This information allows contractors to make informed decisions about how much to allocate for overhead in their current bids.

Overhead consists of indirect costs necessary to run a business but not tied to any specific project, such as administrative expenses, rent, utilities, and insurance. By analyzing historical data, contractors can effectively calculate a realistic percentage for overhead that reflects their business operations and helps ensure profitability while remaining competitive in the bidding process.

In contrast, market analysis focuses more on the current market conditions rather than specific overhead costs. Current labor rates and material cost estimates are certainly important to consider in a bid but do not directly relate to the overhead percentage, which specifically pertains to those indirect costs incurred throughout the execution of projects.
