Key Terms to Review (19)
Activity-based costing: Activity-based costing (ABC) is a method for allocating overhead and indirect costs to specific activities, products, or services based on their actual consumption of resources. This approach provides a more accurate representation of costs by identifying and analyzing the activities that drive costs, leading to better insights for decision-making and cost management.
Actual vs. Budgeted Overhead: Actual vs. budgeted overhead refers to the comparison between the overhead costs that a business incurs during a specific period (actual overhead) and the estimated costs planned before the period begins (budgeted overhead). Understanding this comparison is crucial for identifying variances, which helps management evaluate operational efficiency and make informed decisions for future budgeting and resource allocation.
Applied overhead: Applied overhead refers to the estimated manufacturing overhead costs that are allocated to products based on a predetermined rate, typically using direct labor hours, machine hours, or other activity measures. This concept is crucial for understanding how businesses assign indirect costs to their products, ensuring that the costs reflect the resources consumed during production. By applying overhead costs, companies can determine a more accurate cost per unit, which aids in pricing and profitability analysis.
Budgeted overhead: Budgeted overhead refers to the estimated costs associated with manufacturing that are not directly tied to a specific product, such as utilities, rent, and salaries of support staff. It is essential for planning and controlling costs within an organization, impacting how businesses manage their resources and pricing strategies. Properly estimating budgeted overhead allows companies to set appropriate departmental overhead rates, which are crucial for determining the variances between what was budgeted and what was actually spent.
Capacity variance: Capacity variance is the difference between the actual capacity used in production and the expected or standard capacity that was planned for that period. This variance helps organizations understand how efficiently they are using their resources and whether they are operating within their intended capacity levels. It plays a crucial role in overhead variances, indicating whether fixed overhead costs are being effectively absorbed by actual production levels.
Cost Control: Cost control refers to the process of managing and regulating expenses within an organization to ensure that they remain within the budgeted limits. Effective cost control involves monitoring direct and indirect costs, utilizing budgeting tools, setting performance standards, analyzing variances, and implementing appropriate allocation methods to optimize resources and achieve financial objectives.
Fixed oh spending variance: Fixed overhead spending variance is the difference between the actual fixed overhead costs incurred and the budgeted fixed overhead costs for a specific period. This variance helps organizations understand how much they overspent or underspent on fixed overheads compared to their expectations, enabling them to assess their financial performance and make informed decisions. By analyzing this variance, companies can identify areas where they may need to control costs better or adjust their budget forecasts.
Fixed OH Volume Variance: Fixed OH Volume Variance measures the difference between the actual fixed overhead costs incurred and the budgeted fixed overhead costs based on the actual level of activity. This variance reflects how well a company has managed its fixed overhead in relation to production levels and can indicate whether the company is over or under-absorbing its fixed overhead costs. Understanding this variance is crucial for effective cost management and decision-making.
Fixed overhead variance: Fixed overhead variance is the difference between the budgeted fixed overhead costs and the actual fixed overhead costs incurred during a specific period. This variance helps organizations assess how well they managed their fixed overhead expenses compared to their expectations. Understanding fixed overhead variance is crucial for evaluating overall performance and can inform decisions related to budgeting and cost control.
Overhead Efficiency Variance: Overhead efficiency variance measures the difference between the actual hours worked and the standard hours allowed for the actual output produced, multiplied by the standard overhead rate. It reflects how efficiently overhead resources are used in relation to the production level, helping to identify areas where costs may be controlled better. This variance is crucial for assessing operational performance and informs management about discrepancies that may need addressing for improved productivity.
Overhead rate: The overhead rate is a calculation used to allocate indirect costs, such as administrative expenses, utilities, and rent, to specific cost objects like products or services. This rate helps businesses determine how much of their indirect costs should be included in the total cost of a product, ensuring that pricing and profitability analysis reflect the true economic reality of operations. Understanding the overhead rate is crucial for effective budgeting, financial reporting, and variance analysis.
