Knowing the total and component costs of the product is necessary for price setting and for measuring the efficiency and effectiveness of the organization. Remember that product costs consist of direct materials, direct labor, and manufacturing overhead. A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs. Once a company has determined the overhead, it must establish how to allocate the cost. This allocation can come in the form of the traditional overhead allocation method or activity-based costing..
When is it better to switch from a single POR to activity-based costing (ABC)?
- It means the total number of direct labor hours is taken as the denominator, which is divided by the numerator as the total overhead cost of the company.
- The predetermined overhead rate means Blue Co. will apply a $50 cost to every unit produced during the period.
- The continuous scrutiny and refinement of the chosen allocation base are therefore essential for maintaining the relevance and utility of a company’s cost accounting system.
- The overhead rate of cutting department is based on machine hours and that of finishing department on direct labor cost.
This allows businesses to capture the full cost of production in their accounting. This calculator offers a straightforward predetermined overhead rate formula way to estimate the predetermined overhead rate, making it easier for businesses to manage and allocate their manufacturing overhead costs effectively. A predetermined overhead rate is defined as the ratio of manufacturing overhead costs to the total units of allocation.
Example 3: Multiple Cost Drivers

That means it represents an estimate of the costs of producing a product or carrying out a job. The estimate will be made at the beginning of an accounting period, before any work has actually taken place. Calculating the predetermined overhead rate is a crucial aspect of cost management and allocation in managerial accounting. By using this rate, companies can better understand and control their production costs.
Variance Analysis: Uncovering Hidden Insights

Predetermined overhead rates are also used in the budgeting process of a business. As discussed above, a business must wait until the end of a period to know the actual performance in terms of overheads incurred. However, since budgets are made at the start of the period, they do not allow the business to use actual results for planning or forecasting. Therefore, the business must use a predetermined overhead rate to budget its expenses for the future. To calculate a predetermined overhead rate, divide the manufacturing overhead cost by the units of allocation. The predetermined manufacturing overhead rate is more than a formula it’s a tool to keep costing, pricing, and budgeting predictable.

Built-in analytics help uncover spending trends and quickly flag unusual variances for further investigation. By factoring in overhead costs in this manner, the company arrives at a more accurate COGS. Analyzing these variances gives you crucial feedback on how good your estimates were. Reviewing this data helps you sharpen your forecasting for the next period, leading to a more accurate POHR and better cost control.


The establishment of an estimated overhead rate is not an isolated accounting procedure but a cornerstone of a robust product costing foundation. This foundation represents the systematic accumulation and assignment of all costs incurred to manufacture a product, encompassing direct materials, direct labor, and manufacturing overhead. The predetermined overhead rate serves as the indispensable mechanism for allocating indirect manufacturing costsexpenses that cannot be directly traced to specific productsto the units produced. bookkeeping Its accurate calculation is therefore paramount, as it directly influences the integrity of the total product cost. This rate, as we discussed earlier, is calculated by dividing estimated total overhead costs by an estimated activity level (like direct labor hours or machine hours).
Estimated Activity Level
- With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied.
- By baking reliable indirect cost estimates into your total product costing, POHR becomes the backbone of any effective growth strategy.
- Therefore, waiting for the actual costs and using the information to derive an accurate cost is not an option.
- Again, this predetermined overhead rate can also be used to help the business owner estimate their margin on a product.
- Since overhead costs cannot be easily traced to individual products like direct material or labor costs, overhead rates help to allocate a fair share of these costs based on the activity of making the product.
- So, if you wanted to determine the indirect costs for a week, you would total up your weekly indirect or overhead costs.
This can help to keep costs in check and to know when to cut back on spending in order to stay on budget. Take, for instance, a manufacturing company that produces gadgets; the production process of the gadgets would require raw material inputs and direct labor. These two factors would definitely make up part of the cost Outsource Invoicing of producing each gadget. Nonetheless, ignoring overhead costs, like utilities, rent, and administrative expenses that indirectly contribute to the production process of these gadgets, would result in underestimating the cost of each gadget. The company, having calculated its overhead costs as $20 per labor hour, now has a baseline cost-per-hour figure that it can use to appropriately charge its customers for labor and earn a profit. That is, the company is now aware that a 5-hour job, for instance, will have an estimated overhead cost of $100.
