To arrive at a single hourly or "shop" rate, it is essential to include indirect labor costs alongside direct labor costs. Direct labor costs pertain to the wages paid to workers directly engaged in the project, but this does not encompass additional expenses associated with labor that are not directly attributable to a specific project task.

Indirect labor costs include expenses related to employees who support the workforce but do not work directly on the project, such as supervisors, administrative staff, and other support roles. By combining these indirect labor costs with direct labor costs, a more comprehensive calculation of the total labor expense for the project can be achieved, reflecting the full cost of employing workers.

While overhead costs are also critical in determining the overall cost structure for a project, they typically cover broader expenses such as rent, utilities, and administrative costs associated with running a business, but they are not classified directly under labor costs. Therefore, indirect labor costs effectively round out the calculation of labor expenses necessary for determining an accurate "shop" rate.
