Standard Variable Overhead Cost: Detailed Explanation and Importance

A comprehensive guide to understanding Standard Variable Overhead Cost, its historical context, types, key events, detailed explanations, mathematical models, importance, applicability, examples, considerations, related terms, comparisons, interesting facts, and FAQs.

Historical Context

Standard costing systems have roots tracing back to the early 20th century when the need for more structured and precise cost accounting methods became apparent. With the advent of mass production techniques, companies required efficient ways to control and allocate overhead costs, leading to the development of standard variable overhead cost systems.

Types/Categories

• Manufacturing Overhead: Costs related to manufacturing processes that vary with production levels, such as utilities and indirect labor.
• Non-Manufacturing Overhead: Overheads related to sales, administrative functions, and other non-production activities, which can also vary depending on the level of activity.

Key Events

• Industrial Revolution: The increased production scale necessitated systematic cost accounting.
• Early 20th Century: Formalization of standard costing and overhead allocation techniques.
• Post-WWII: Enhanced cost accounting practices with more refined overhead allocation models.

Detailed Explanations

Definition

A standard variable overhead cost is the cost that is applied to the production process, calculated using the standard time allowed for producing a unit or performing an operation and the standard variable overhead absorption rate per unit of time.

Mathematical Models

The formula to calculate Standard Variable Overhead Cost:

$$ \text{Standard Variable Overhead Cost} = \text{Standard Hours Allowed} \times \text{Standard Variable Overhead Rate} $$

Example Calculation

Suppose a company determines the standard variable overhead rate to be $5 per machine hour, and the standard time to produce one unit is 3 hours. The standard variable overhead cost for one unit is:

$$ \text{Standard Variable Overhead Cost} = 3 \, \text{hours/unit} \times 5 \, \text{\$/hour} = 15 \, \text{\$/unit} $$

Importance

Understanding and managing standard variable overhead costs is crucial for:

• Cost Control: Helps in identifying and controlling variable overhead expenses.
• Budgeting: Facilitates accurate budget preparation.
• Performance Measurement: Assists in comparing actual costs with standard costs to assess performance.
• Pricing Decisions: Provides a foundation for setting competitive and profitable prices.

Applicability

Standard variable overhead costs are applicable in various industries, particularly manufacturing, where overhead costs vary with production volume.

Examples

• Manufacturing Company: Calculating the variable overhead costs for producing different batches of products.
• Service Industry: Estimating the variable costs associated with varying service delivery times.

Considerations

• Accuracy of Standards: The reliability of standard costs depends on the precision of the estimated standards.
• Regular Updates: Standards should be regularly reviewed and updated to reflect current conditions and practices.

Related Terms

• Fixed Overhead Cost: Overhead costs that do not vary with production levels.
• Absorption Costing: A costing method that includes all overhead costs in the cost of production.
• Flexible Budget: A budget that adjusts for varying levels of activity.

Comparisons

• Standard Variable Overhead Cost vs. Fixed Overhead Cost: Variable overhead costs fluctuate with production levels, while fixed overhead costs remain constant.

Interesting Facts

• Pioneered by Engineers: Early systems of standard costing and overhead allocation were pioneered by industrial engineers seeking to improve efficiency.

Inspirational Stories

• Henry Ford: Implemented advanced cost accounting practices in the early 20th century to optimize production costs at the Ford Motor Company.

Famous Quotes

• “If you can’t measure it, you can’t manage it.” – Peter Drucker

Proverbs and Clichés

• “Penny wise and pound foolish.”

Expressions

• “Cutting costs to the bone.”

Jargon

• Absorption Rate: The rate at which overhead costs are allocated to units of production.
• Variance Analysis: The process of analyzing the differences between actual and standard costs.

Slang

• Oomph Factor: Extra efforts needed to meet or exceed standard cost efficiency.

FAQs

Why is it important to calculate standard variable overhead costs?

It is essential for accurate budgeting, cost control, and performance measurement.

How often should standard variable overhead rates be updated?

They should be reviewed and updated at least annually or when significant changes in production processes occur.

Can standard variable overhead cost be applied to service industries?

Yes, it can be applied to any industry where costs vary with activity levels.
