Revision variance, also known as planning variance, is a crucial concept in standard costing that arises from differences between an originally set standard and a modified standard, which reflects changed circumstances. This concept helps in measuring the impact of these changes on performance, providing valuable insights for financial analysis and management.
Historical Context
Standard costing and variance analysis have been fundamental components of management accounting for decades. They emerged in the early 20th century as industrial production expanded, necessitating more sophisticated cost control mechanisms. Over time, the concept of revision variance was developed to better accommodate changes in operational environments and expectations.
Key Concepts
Definition
Revision Variance: The difference between the standard cost as originally set and the standard cost as revised to reflect current circumstances. It helps in identifying and measuring the impact of environmental changes on organizational performance.
Types/Categories
- Original Standard: The cost estimates set initially during the planning phase.
- Revised Standard: The updated cost estimates reflecting current conditions.
- Operational Variance: Measures the impact of operational performance against the revised standards.
Key Events
- Setting Original Standards: Establishing the initial cost estimates based on historical data and expected future conditions.
- Revision of Standards: Modifying the original standards to reflect current conditions such as market price changes, new regulations, or technological advancements.
- Calculation of Operational Variance: Assessing how well actual performance aligns with the revised standards.
Detailed Explanations
Mathematical Formulas/Models
To compute revision variance, the following formula is commonly used:
Where:
- Revised Standard Cost: The updated cost reflecting the current circumstances.
- Original Standard Cost: The initial cost set during the planning phase.

Importance and Applicability
Revision variance plays a critical role in:
- Performance Evaluation: Helps organizations assess how well they adapt to changing conditions.
- Financial Planning: Provides a basis for revising budgets and forecasts.
- Decision Making: Informs strategic decisions by highlighting areas requiring attention or adjustment.
Examples
- Example 1: A manufacturing company initially sets a standard cost of $100 per unit. Due to increased material prices, the revised standard cost is $110 per unit. The revision variance is $10 per unit.
- Example 2: A tech company sets an original standard cost of $200,000 for a project. Due to changes in labor costs and technology, the revised standard is $220,000, resulting in a revision variance of $20,000.
Considerations
- Accuracy of Revised Standards: Ensuring that revised standards accurately reflect current conditions.
- Impact on Operational Variance: Understanding how revision variance affects the assessment of operational performance.
Related Terms with Definitions

- Operational Variance: The difference between actual performance and revised standards.
- Planning Variance: Another term for revision variance.
Comparisons
- Revision Variance vs. Operational Variance: Revision variance measures changes in standards, while operational variance measures performance against the revised standards.
Interesting Facts
- Historical Evolution: The concept of revision variance has evolved to address the dynamic nature of modern business environments.
- Broader Applications: Used not only in manufacturing but also in service industries and project management.
