What is general contractor's overhead and profit?

General contractor's overhead and profit refer to the additional costs and markup that contractors add to their bids to cover their business expenses and ensure profitability. Overhead includes indirect costs such as office rent, utilities, and administrative salaries, while profit is the margin added on top of project costs to generate income. Typically, these percentages can vary, but overhead might be around 10-20%, while profit margins can range from 5-15%, depending on the project and market conditions. Together, they ensure that the contractor remains financially viable while completing the project.
