Manufacturing Overhead Formula: How to Calculate

This is calculated by dividing the estimated manufacturing overhead costs by the allocation base, or estimated volume of production in terms of labor hours, labor cost, machine hours, or materials. Manufacturing overhead (or factory overhead) is the sum of all indirect costs incurred during the manufacturing process. You can calculate manufacturing overhead costs by adding your indirect expenses, such as direct materials and labor, into one total. The overhead rate is calculated by adding your indirect costs and then dividing them by a specific measurement such as machine hours, sales totals, or labor costs. Direct costs are the costs that directly impact production such as direct labor, direct materials, and manufacturing supplies. Manufacturing overhead (MOH) cost is the sum of all the indirect costs which are incurred while manufacturing a product.

  1. Both COGS and the inventory value must be reported on the income statement and the balance sheet.
  2. You can use this formula to calculate manufacturing overhead, which should appear on your cost of goods income statement as well as any other relevant balance sheets.
  3. Salespeople on the road are getting the same real-time data that managers and workers are the floors are using to run production.
  4. Get reports on project or portfolio status, project plan, tasks, timesheets and more.

These overhead costs don’t fluctuate based on increases or decreases in production activity or the volume of output generated during manufacturing. These overhead costs aren’t influenced by managerial decisions and are fixed within a specified limit based on previous empirical data. They include equipment depreciation costs during manufacturing, rent of the facility, land used for inventory, and depreciation of the facility. At the end of the period, the business reconciles the difference between the estimated manufacturing overhead cost and the actual manufacturing overhead cost through overhead variance analysis. This analysis helps companies identify inefficiencies in their production processes and make necessary adjustments to improve operations. It may include salaries, wages, and benefits paid to employees not directly involved in the production process, such as Supervisors and Maintenance Personnel.

Overhead costs are expenses that are not directly tied to production such as the cost of the corporate office. To allocate overhead costs, an overhead rate is applied to the direct costs tied to production by spreading or allocating the overhead costs based on specific measures. The overhead rate, sometimes called the standard overhead rate, is the cost a business allocates to production to get a more complete picture of product and arrears definition and usage examples service costs. The overhead rate is calculated by adding indirect costs and then dividing those costs by a specific measurement. Identify all the manufacturing process’s indirect costs, then add all the indirect expenses to calculate the manufacturing overhead. While calculating overhead costs is an important step in producing accurate financial statements, not all of these calculations take place after work has been completed.

Highlight or take note of which items should be included in overhead costs. Estimated overhead is decided before the accounting year
begins in order to budget and plan for the coming year. This is done as an
educated guess based on the actual overhead costs of previous years. These items can be essential to production but do not
qualify as parts of specific products, therefore they should be accounted for
as indirect materials. Keeping a record of these costs helps you determine your business’s efficiency and performance. Financial overhead consists of purely financial costs that cannot be avoided or canceled.

These are any costs that don’t relate to the direct manufacture of a product. Therefore, to find how much manufacturing overhead a company has, it uses a manufacturing overhead formula that adds up all costs that do not link to a specific product. To calculate manufacturing overhead, you have to identify all the overhead expenses (like the three types mentioned above). Sometimes these are obvious, such as office rent, but sometimes, you may have to dig deeper into your monthly expense reports to understand what’s happening.

Determining total manufacturing overhead cost

Unless a cost can be directly attributable to a specific revenue-generating product or service, it will be classified as overhead, or as an indirect expense. You also need to take into account applied overhead costs and how to find manufacturing overhead applied. If you need to know how to calculate manufacturing overhead applied costs, you first need to know what would count as an applied cost. Expenses for trade shows go towards displaying and marketing your products, which are indirect costs and thus not included in overhead costs. There will almost always, however, exist a difference
between the applied overhead and the actual overhead calculated at the end of the
accounting period. Then, actual overhead costs are reconciled with the applied
overhead costs to make sure the correct numbers end up on the balance sheet.

What are the different types of indirect costs related to manufacturing overhead?

Step #3
Determine the total cost of other overhead expenses for the same period, such as rent, utilities, insurance, and taxes. For example, you can use the number of hours worked or the number of hours machinery was used as a basis for calculating your allocated manufacturing overhead. Manufacturing units need factory supplies, electricity and power to sustain their operations.

We’ll get to the formula in a little bit, but first let’s set up the building blocks of understanding exactly what is necessary for tracking overhead costs and why. This includes understanding what contributes to expenses rather than overhead or operational costs. This applied overhead rate can now be used for job costing
as well as for calculating the estimated manufacturing overhead for the year. Manufacturing overhead also refers to the factory overheads or Manufacturing support costs. Manufacturing overhead costs do not include administration and advertisement expenses. This cost is incurred for materials which are used in manufacturing but cannot be assigned to any single product.

This scenario represents the shortest possible route that product travels from factory floor to customer. Things like sales teams, distribution, HR, and administrative teams are unnecessary to your making a profit.

Step #1
Determine the total cost of indirect materials used in the production process, such as a month or a year, during a given period. It includes lubricants, cleaning supplies, and other materials used in the manufacturing process. Accurately calculating your company’s manufacturing overhead costs is important for budgeting.

An overhead cost can be categorized as either indirect materials, indirect labor, or indirect expenses. Of course, management also has to price the product to cover the direct costs involved in the production, including direct labor, electricity, and raw materials. A company that excels at monitoring and improving its overhead rate can improve its bottom line or profitability. The equation for the overhead rate is overhead (or indirect) costs divided by direct costs or whatever you’re measuring. Direct costs typically are direct labor, direct machine costs, or direct material costs—all expressed in dollar amounts. Each one of these is also known as an “activity driver” or “allocation measure.”

Direct labor is a variable cost and is always part of your cost of goods sold. If you want to measure your indirect costs against direct labor, you would take your indirect cost total and divide it by your direct labor cost. The allocated manufacturing overhead formula focuses on assigning indirect costs to specific products or cost centers.

None of these expenses is directly tied to the actual manufacturing process. However, it would be impossible for the business to manufacture its products to a high standard without these. This is why they’re considered indirect costs and part of your organization’s overhead. Aside from direct manufacturing costs, you must know how to calculate manufacturing overhead.

Associated financial costs

While both the overhead rate and direct costs can impact final product cost, along with your balance sheet and income statement, they are two different things. Knowing how to calculate manufacturing overhead provides valuable insights into the quality and efficiency of your business. Regular monitoring of overhead costs and overhead rates tells you whether your business is reaching its potential. Manufacturing overhead refers to the indirect costs of creating a product. There’s more to manufacturing than the men and women handling raw materials and making a product out of them.
