The burden rate, also known as the overhead rate or indirect cost rate, is a crucial metric for businesses, especially in service-oriented industries or manufacturing. It represents the cost of indirect expenses that are not directly tied to a specific product or service but are necessary for the overall operation of the business. Calculating the burden rate helps businesses understand the true cost of labor and services, enabling them to set accurate pricing, manage costs effectively, and assess profitability.
Essentially, the burden rate answers the question: "How much does it cost us per hour of direct labor to cover all our indirect expenses?" These indirect expenses can include a wide range of costs, such as:
By accurately calculating and applying the burden rate, businesses can ensure that all operational costs are accounted for when determining the price of their goods or services, preventing underpricing and potential financial losses. It's a vital tool for financial planning and strategic decision-making.
How to Calculate Burden Rate
The burden rate is typically calculated using the following formula:
Burden Rate = Total Overhead Costs / Total Direct Labor Hours
This formula provides the overhead cost allocated to each direct labor hour. Once you have this rate, you can add it to the direct labor cost of an employee or a project to determine the fully burdened labor cost.
Fully Burdened Labor Cost = Direct Labor Cost + (Burden Rate * Direct Labor Hours)
Example Calculation
Let's consider a small consulting firm. They have the following figures for a given period:
Direct Labor Cost: $80,000 (This represents the actual wages paid to employees for their direct work on client projects.)
Total Overhead Costs: $120,000 (This includes rent, utilities, administrative salaries, software subscriptions, etc.)
Total Direct Labor Hours: 2,500 hours (This is the total number of hours billed directly to client projects by all employees.)
Using the burden rate formula:
Burden Rate = $120,000 / 2,500 hours = $48 per direct labor hour.
This means that for every hour an employee works directly on a client project, the company incurs an additional $48 in overhead costs.
Now, let's calculate the fully burdened labor cost for a project that took 50 direct labor hours:
Direct Labor Cost for the project = 50 hours * $30/hour (example employee wage) = $1,500
Burden Cost for the project = 50 hours * $48/hour (burden rate) = $2,400
This comprehensive cost ($3,900) should then be used when setting the price for the client service to ensure profitability.
