Cost Management Using Variance
Analysis
Variance
Analysis is a technique used for:
a. Cost Control - Monitor Actual Expenditures against,
should cost.
b. Profit Control - Which a large part is
facilitated by cost control.
To be able
to do Variance Analysis you need:
1. A cost accounting system that records
the costs in the format that allows matching against planned cost.
2. Budgeted costs that are realistic,
doable and accepted by those responsible for meeting them.
3. The best way to develop
"should" cost is through defining standard through actual measurement (engineers
costs). When this is done for the whole
company, it is called Standard Costing.
4. Standard Costing is very expensive
(i.e. must develop and keep standards up-to-date). Pay
for mass production companies where due to low profit margins cost must be carefully
controlled (i.e. Proctor & Gamble, McDonalds, Medical Centers).
5. Where acceptable historical costs (cost
database) are used to specify a should cost:
a. Last years actual cost plus adjustment
for change.
b. Statistically derived cost function.
The most widely used technique by
management to maintain cost and profit control is
The Budget
--
Usually each of these sectors has
specific individual budget that cover areas that management wants to monitor.
Sales Revenue - By individual product, sales office, customer
Factory Overhead - Maintenance, Quality Control, Engineering
General + Administrative - Legal Dept., Human Relations, Public Relations
1. Communicates
Goal
2. Defines
Constraints
3. Provides
Accountability
4. Sets
Targets to be Met
5. Provides
Systems Perspective
Necessary for Budgets to Work
1. People have
confidence in the budget system being used and budget figures set to be met
2. Is utilized
by management
3. Management
does not use to set blame, but as an indicator for possible action to be taken
4. Fast
feedback of performance to the managers so they can take corrective action
5. They are
not too administratively burdensome
Variance Analysis Involves
1. Defining
the gap between the budget goal and actual performance
2. Investigating
to determine cause
3. Identifying
potential responses
4. Taking
action
Typical variance that are calculated to
explain why profit target is not met.
Can either be sales revenue lower,
costs higher or a combination of both.
Flexible Budgets
For example you do not know at what operating level you are
going to run. What you know is that there is
a fixed cost and variable cost.
Say the
fixed is $10,000 and variable cost is $5.00 per hour.
The
"Should" Cost if
10,000
hrs. is $10,000 + 10,000(5) =
$ 60,000
25,000
hrs. is $10,000 + 15,000(5) =
75,000
20,000 hrs.
is $10,000
+ 20,000(5) = 100,000
So if in one
month 10,000 hours are worked, the budget is $60,000.
If 20,000 hours were worked, $100,000 is the amount that should have been
spent.
Example Problem
Standard - for one unit | Unit Cost |
|
DM 1lb. Material $26.00 per lb. | = | 26.00 |
DL 12 hrs. labor @ $12.00 per hour |
= | 144.00 |
Actual
Produced 3,600 units
Bought and used 4,000 lbs. of material
Costing $108,000
Used 50,400 hours of direct labor
Paying $630,000
Another Word
on Setting of Standards
They
have to be realistic to be effective and useful.
Say in a
production department you have 40 machines - what should be the number of production hours
available?
Theoretically
= 40 machines x 8 hours/day x 250
= 80,000 hours/year
Practically
they only work 80% of the time due to downtime, Personnel HB Sense
.8(80,000) = 64,000
that would
be 100% capacity utilization on one shift. (i.e.
currently attainable standards).
Chances are
you will be working at 80% of capacity or .8(64,000)=51,200.
The flexible budget will allow you to determine what
the costs should be at that production level.
