Predetermined Overhead Rate Formula, Explanation and Example

Predetermined Overhead Rate Formula, Explanation and Example

The predetermined overhead rate can be either overapplied or underapplied, depending on how accurate the company estimated the manufacturing overhead. The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming. The limitations and problems of the predetermined overhead rate are that they are not always realistic, accurate decision-making can be affected, and historical costs do not always match current costs. Using the planned annual amounts for the upcoming year reduces the fluctuations that would occur if monthly rates were used. The companies use different allocation bases when calculating their predetermined overhead rates. A predetermined overhead rate is an allocation rate that is used to apply an estimated cost of manufacturing overhead to either products or job orders.

It is known as either over-absorption or under-absorption of overheads. The difference between estimated and actual overhead is adjusted in the books as under or over the recovery of overhead.

Importance of Overhead

It is possible that the overhead rate may not be as close to what the calculations produce because both the denominator and numerator are estimates. Most manufacturing and service organizations use predetermined predetermined overhead rate rates. Let’s say we want to calculate the overhead cost of a homemade candle eCommerce business. Then, they’ll need to estimate the amount of activity or work that will be performed in that same time period.

This information can help you make decisions about where to cut costs or how to allocate your resources more efficiently. The cost of your office rent would be considered overhead because it’s something you have to pay regardless of how many t-shirts you sell. But before we dive deeper into calculating predetermined overhead, we need to understand the concept of overhead itself. An example is electricity costs that vary by weather and time of day. Let’s take an example to understand the calculation of Predetermined Overhead Rate in a better manner.

How to calculate the Overhead budget using the rate

Suppose the budgeted cost of overheads for the departmental store amounts to $20,000 per month, and the budgeted level of production is 10,000 per month. The predetermined rate of overheads can be calculated by putting the values in the above formula. The molding department bases its overhead rate on its machine hours. Whereas the packaging department bases its overhead rate on labor hours.

If there is an abrupt rise or fall in manufacturing overhead, historical information may not be applicable. An analysis later revealed that $48,000 was actually the correct amount to be allocated to inventory.

Financial PlanningFinancial planning is a structured approach to understanding your current and future financial goals and then taking the necessary measures to accomplish them. Because this does not begin and end in a specific time frame, it is referred to as an ongoing process.

Figure 8.41shows the monthly manufacturing actual overhead recorded by Dinosaur Vinyl. As explained previously, the overhead is allocated to the individual jobs at the predetermined overhead rate of $2.50 per direct labor dollar when the jobs are complete. The predetermined overhead rate is the quotient of the estimated total manufacturing overhead cost for the coming period divided by the total labor hours or machine hours for the coming period.

Predetermined overhead rates are essential to understand for eCommerce businesses as they can be used to price products or services more accurately. They can also be used to track the financial performance of a business over time. First, you need to figure out which overhead costs are involved, and then create a total of this amount. If you have a large company, you may need to determine an allocation base for each department. Following this, you can assess which costs are similar and therefore which allocation base they belong to. Establishing a predetermined overhead rate for your business can give you a tool to help keep expenses in proportion with sales and production volumes. Monitoring a well-defined rate provides a quick signal that lets you know when it’s time to review spending and, in doing so, will help you protect your profit margins.

• This rate is often used to speed up the closing of books, as it does not require the compilation of actual manufacturing overhead cost during the closing period.
• Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation.
• The company estimates a gross profit of $100 million on total estimated revenue of $250 million.
