Common Mistakes with Overhead Allocation
Overhead allocation, also known as indirect cost allocation, is an important accounting tool used by businesses to allocate indirect costs to their products or services. These indirect costs include items such as rent, utilities, and administrative expenses that cannot be easily traced to a specific product or service. Overhead allocation is a complex process that involves allocating these costs to products or services based on a predetermined formula or percentage. However, despite its importance, businesses often make common mistakes when it comes to overhead allocation. In this article, we will discuss these mistakes and how to avoid them.
1. Using a Single Overhead Rate for All Products
One of the most common mistakes businesses make is using a single overhead rate for all their products or services. This method assumes that all products or services consume overhead costs in the same proportion. However, this may not always be the case. For example, a high-volume product may consume more overhead costs compared to a low-volume product. Using a single overhead rate can lead to distorted costs and inaccurate pricing decisions. Instead, businesses should use multiple overhead rates that take into account the unique characteristics of each product or service.
2. Including Non-Production Costs in Overhead Allocation
Another mistake businesses make is including non-production costs in their overhead allocation. Non-production costs, such as selling and marketing expenses, are incurred to generate sales and should not be allocated to products. This can result in an inflated product cost, leading to incorrect pricing decisions. Non-production costs should be assigned directly to the respective cost centers, such as the sales or marketing departments.
3. Using Outdated Overhead Rates
Overhead rates are calculated based on historical data, such as previous year’s expenses and production levels. However, these rates may become outdated as expenses and production levels change. Many businesses make the mistake of using outdated rates, resulting in inaccurate product costs. Overhead rates should be reviewed and updated regularly to reflect current expenses and production levels accurately.
4. Not Considering Seasonal Effects
Some businesses experience seasonality in their production or sales, which can affect their overhead costs. For example, a retail business may have higher overhead costs during the holiday season due to increased sales and promotional expenses. Using a single overhead rate for the entire year may not accurately reflect the seasonal fluctuations in overhead costs. Businesses should consider using different overhead rates for each season to ensure accurate allocation of costs to products or services.
5. Failing to Reevaluate Overhead Allocation Method
As businesses grow and evolve, their overhead allocation method may become outdated or inefficient. For instance, a business that has expanded its product line may need to revise its overhead allocation method to reflect the new products’ unique characteristics. Failing to reevaluate the overhead allocation method can result in distorted product costs and misleading financial reports. Businesses should regularly review their overhead allocation method and make necessary changes to ensure accurate product costs.
In conclusion, overhead allocation is a crucial aspect of accounting that can significantly impact a business’s financial performance. Businesses must avoid the common mistakes mentioned above to ensure accurate product costs and pricing decisions. Using multiple overhead rates, excluding non-production costs, regularly updating overhead rates, considering seasonal effects, and reevaluating the allocation method are crucial steps to avoid these mistakes. By understanding and avoiding these mistakes, businesses can improve their overhead allocation process and make informed decisions that contribute to their overall success.
