11. Standard Costing and Variance analysis Flashcards
Define standard cost
The planned unit cost of a product, component or service
What is meant by standard hour
The amount of work achievable at standard efficiency levels in an hour
What is the purpose of standards
- To set budgets
- Prediction for decision making and resorce allocation
- Control mechanism: variance analysis
- Performance evaluation
- Inventory valuation
What is meant by management by exception
In variance analysis - where focus is on activities which require attention and ignoring those which appear to be conforming to expectations
When is standard costing mainly used
- When there is a degree of repition in production
What are the bases/levels at which standards are set at
- Ideal standard
- Attainable standard
- Current standard
- Basic historic standard
Ideal standard
Assumes optimum level of efficiency
Attainable standard
Makes an allowance for normal inefficiecies but also includes improvement
Current standard
Based on current efficiency levels and achievements
Basic/Historic standard
Not updated regularly to show changes over long term
What are the criticisms of standard costing
- Standard costing works best in stable environment
- Regular revisions are neeeded for standard costing
- Standard costing is less useful in customised product environment
- Standard costing is potentially misleading when JIT is used - focus on wrong issues and negatvie behaviour
What is JIT
Just in time system - objective is to produce products as they are required by a customer rather than for stock
Which two costing systems comply with standard cost
Marginal - total variance
Absorption costing - fixed OAR per unit
What are considerations when setting standards relating to direct material
- Purchase contracts agreed
- Pricing discussion with regular suppliers
- Forecast and movement of prices
- Bulk purchase discounts
- Material quality
- Anticipated inflation
What are considerations when setting standards regarding direct labour
- Agreements of pay rises/bonuses
- Experience of staff
- HR department
How does price inflation cause difficulties in setting realistic standard price
- If current price was used in standard: reported price variance would become adverse as prices go up
- If estimated average price were used: price variance would be favourable in first half and adverse in second half assuming price goes up gradually
Why is standard costing still useful in times of inflation
- Usage and efficiciency variances will still be meaningful
- Inflation is measurable - effects can be removed
- Standard costss can be revised
