Week 8- Variance analysis Flashcards
(38 cards)
What is standard costing?
Standard costing is a control technique which
compares standard costs and revenues with
actual results to obtain variances which are used
to stimulate improved performance.
Accountants and representatives from other
functions such as engineers, personnel
department managers, and production managers
combine efforts to set standards based on
experience and expectations.
Ideal standards assume peak efficiency at all
times. They are therefore not going to be achieved
in most cases.
Practical standards allow for normal machine
downtime and other work interruptions and that
can be attained through reasonable, though highly
efficient, efforts by an average worker.
They are challenging but achievable targets and are
therefore most frequently used.
What is a standard cost?
– A standard cost is an estimated unit cost.
– Usually expressed on a per unit basis.
– Benchmark for measuring performance against actual
results.
What are variances? They may relate to changes in what? What are U and F variances?
- Quantity
- Price
• Variances which reduce income or increase
costs are unfavourable (or adverse ) U (or A)
• Variances which increase revenue or reduce
costs are favourable (F)
What is a statis budget?
Expected (budgeted) amounts for a single
level of planned output.
Based on one level of output: no adjustment
is made to budgeted units
What are flexible budgets?
Expected (budgeted) amounts for a range of
output levels (“flexed” version of static
budget).
Budgeted amounts are adjusted (ie flexed) to
recognise the actual level of output. A flexed
budget is calculated after the period end
using the actual level of output
What are deficiencies of statis budgets?
• Problem: In static budget based variance analysis,
variances caused by changes in output cannot be separated from variances caused by changes in price/cost.
Flexible budgets adjust budgeted standards for
actual output. Thereby, variances caused by
changes in output levels can be separated from
variances caused by changing prices and levels of input.
static budget variance
static budget variance=actual results - static budget amount
Sales volume profit (or contribution) variance
The sales volume variances are those variances which are created
because actual sales volume is different from the budgeted sales
volume .
Sales volume variance in the context of contribution and profits:
(Actual Sales Units – Budget Sales Units ) × Standard Margin
Where Standard margin = Standard contribution per unit
(marginal costing)
Or
Standard profit per unit (absorption costing)
What are the 3 levesl of variance analysis
Static budget variance: flexible budget variance + sales volume variance
flexible budget varience: price variance + efficiency variance (for input factors)
static budget variance
flexible budget variance
Formula sheet
ex: Flexible budget variance= actual cost - flexible cost
What are price and efficiency variances?
•Price and efficiency variances are concerned
with the actual and budgeted prices and
quantities of inputs (such as direct materials
purchased or used).
FMsheet
Material Usage (Efficiency) - If unfavourable:
- Defective material
- Excessive waste (abnormal loss)
- Unskilled labour
- Pilferage
- Errors in allocating material to jobs
- Obsolete machinery (or highly depreciated)
Who is responsible for Unfavourable
MATERIAL USAGE VARIANC?
•Production manager is responsible to keep
tabs on unnecessary or extravagant use of
materials.
•If purchase manager purchases low quality
materials to improve the direct materials price
variance then purchasing department would be
held accountable for the variance.
Material Usage - If favourable:
Material used of higher quality than standard i.e. stricter quality control • More effective use made of material • Errors in allocating material to jobs • Automated processes or modern machinery • Skilled labour • Training and development of workforce OR motivated workforce
Material Price - If unfavourable:
-Price increase
• Careless purchasing
• Better quality material
• Inflation (increase in all prices)
• Not benefitted from bulk discount
• Increased transportation costs
• Just in time management can lead to material
shortages and may have needed urgent orders
-damaged goods sold for lower price
-original sales price was unrealistic and was lowered
Who is responsible for unfavourable MATERIAL PRICE VARIANCE?
•Primarily Purchasing department is responsible
and accountable to place orders for direct
materials so this variance is generally considered
the responsibility of purchase manager.
•Beware! that should not always be the case.
above reasons clarify that the materials price
variance may or may not be the result of
inefficiencies of the purchasing department.
How to determine true material cost?
Direct materials price standards should reflect the
final delivered cost of the materials.
In some instances, when oil prices are high.
shipping costs exceed the cost of the cargo itself.
e.g. In Oct 2007, it cost about $88 to ship a ton of
iron ore from Brazil to Asia; whereas, the iron ore
itself was only costs $60 per ton.
Material Price – If favourable:
Unforeseen discounts received e.g. bulk
purchasing leading to discounts
• Greater care in purchasing; cheaper supplier
• Lower quality material
• Efficiencies in upstream value chain (efficient
procurement) e.g. Economic order quantity e.g.
economically best courses of action regarding
reordering point, ordering cost, carrying cost,
order lead time, Purchasing cost per unit
-discount (ex: bulk discount)
-weak exchange rates
Suggested causes of material variance:
- change of supplier
- increased purchase price
- increased delivery costs
- exchange rates are weak
- more material used
- cheaper material use that increases wastage and more units to be reproduced
- shortage of material, thus increasing price
- seasonal variation
- careless purchasing
- inflation
- not benefited from bulk discount
- increased transportation costs
- just in time management
Explaining unfavourable variances:
Labour efficiency variance
Inexperienced/junior doctors
Poor level of motivation workers
Tiredness
Equipment needs improvement?
Purchase of low quality materials (more relevant in
manufacturing businesses)
Poor supervision
Unrealistic (even dangerous) expectations for efficiencies and
therefore wrong standard length of times.
Explaining unfavourable variances: Labour rates (price) variance
The hourly pay for doctors may have been higher
than expected, because…
Some medics may have worked overtime and therefore cost
more
Comparatively senior staff (more expensive) may have been
available to offer the services
Skills shortages may have required hiring at different pay rates
There may have been promotions of staff into higher pay
levels
The outcome of contract negotiations with union may have
favoured the medics
Variable OH efficicency variance
Variable OH spending variance
FM SHEET
Possible reasons for
VOH EFFICIENCY VARIANCE
• A variance does not necessarily mean that a company
has incurred less/more actual overhead, it simply
means that there was a deterioration in USAGE of
the allocation base (e.g. as machine hours here) that
was used to apply overhead.
• Actual machine hours used have been higher than the
budgeted machine hours. It could be for a number of
reasons e.g. planning errors, old machinery, poor
quality of raw materials and therefore more difficult
to work with etc.
Possible reasons for
VOH SPENDING VARIANCE
Suppliers of various overhead services (e.g.
electricity supplies) may have changed their
prices, which have not yet been reflected in
updated standards.
• OH Absorption basis (e.g. labour hours) may
not have been the most appropriate one as a
standard for absorbing variable overheads
–Discount on purchase of indirect materials and supplies because of large order sizes.
-A sudden decrease in the prices of indirect materials or the rates of indirect labor that were not expected at the time of setting overhead standards.
