Burden rate definition
/What is Burden Rate?
The burden rate is the allocation rate at which indirect costs are applied to the direct costs of either labor or inventory. You should add burden to the direct cost of either labor or inventory in order to present the total absorbed cost of these items. The two situations in which the burden rate is used are noted below.
Burden Rate for Labor
Payroll taxes and benefits are added to an employee's wages to arrive at the total cost of labor for that individual. The burden rate is the dollar amount of burden (i.e., overhead) that is applied to one dollar of wages. For example, if the annual benefits and payroll taxes associated with an individual is $20,000 and his wages are $80,000, then the burden rate is $0.25 per $1.00 of wages.
Burden Rate for Inventory
Manufacturing overhead costs are added to the direct material and direct labor costs of an inventory item to arrive at the total cost (the fully burdened cost) of that item. This type of burden is sometimes applied based on the amount of direct labor cost charged to a product, but may use some other measure, such as the amount of machine time used. For example, if the amount in the manufacturing overhead cost pool is $10,000 and there are a total of 1,000 hours of machine time used by all products, then the burden rate is $10.00 per machine hour used.

How to Calculate a Labor Burden Rate
The formula for calculating labor burden is as follows:
Labor burden cost ÷ Payroll cost = Labor burden
It is particularly important to include the burden rate when reporting on the full cost of labor, because some benefit packages can increase the total cost of labor to a point more than 50% greater than the cost that is initially indicated by an examination of payroll records. This information is useful when deciding whether to outsource operations to low-cost labor regions, as well as to decide whether to lay off employees. The burden rate concept is especially worthwhile in situations where the bulk of a company's business comes from directly billable hours, where you need to be as precise as possible in tracking profits by person.
How to Calculate an Inventory Burden Rate
The formula for calculating inventory burden is as follows:
Manufacturing overhead cost ÷ Activity measure = Inventory burden
The association of burden with inventory is required by the accounting standards (including Generally Accepted Accounting Principles and International Financial Reporting Standards), so that the full cost of inventory is reported in a company's balance sheet. This information is of less use for internal decision-making purposes, where managers typically use direct costs instead.
Using Burden Rate to Make Business Decisions
By applying a burden rate to your other costs, you gain a better view of the total cost of a cost object - such as an employee, product, or store. For example, you may find that the fully burdened cost of a consultant is $120 per hour. If she is currently generating $110 of revenue per billable hour, then you are losing money on her services. This may call for an increase in her hourly billing rate.
Similarly, if you apply a burden rate of $10 to each product manufactured, you may find that you are selling the product at a price that will not generate a profit for you over the long term. This may result in a decision to stop offering the product for sale, or perhaps a significant price increase to ensure that you cover the fully burdened cost of each unit sold.
Burden Rate Best Practices
There are several best practices to keep in mind when formulating a burden rate, which are as follows:
Identify all indirect costs. Gather comprehensive data on all indirect labor costs, including payroll taxes, employee benefits, workers’ compensation, and facility overhead. This ensures that the burden rate reflects the full cost of employing labor beyond direct wages. Excluding key costs can lead to underpricing and profit erosion.
Allocate costs appropriately. Assign indirect costs to cost centers or departments based on logical drivers such as headcount or direct labor hours. Avoid arbitrary allocations to maintain accuracy. Use activity-based costing if the cost structure is complex and varies across functions.
Use consistent time frames. Match the period used for calculating burden costs (e.g., annually or monthly) with the labor hours or wages being analyzed. This consistency ensures the rate accurately reflects current operational conditions. Misaligned time periods can skew the resulting burden rate.
Regularly update the rate. Recalculate the burden rate periodically to account for changes in benefit costs, tax rates, or business operations. Using outdated rates can misstate labor costs and affect pricing or profitability. Quarterly or annual updates are common depending on volatility.
Document assumptions. Keep a clear record of all included costs, allocation methods, and assumptions used in the calculation. This supports transparency and simplifies future revisions. Documentation also aids in internal reviews and audits.
Benchmark against industry standards. Compare your burden rate with industry averages to evaluate competitiveness and efficiency. Large variances may signal operational inefficiencies or misallocations. Use benchmarking as a diagnostic, not a substitute for thorough internal analysis.
Use software tools where applicable. Employ ERP or cost accounting systems to automate burden rate calculations and maintain consistency. These tools can also help track historical trends and forecast future rates. Automation reduces manual errors and improves reporting accuracy.
