Traditional Costing System
9-4
Traditional cost systems were created when manufacturingprocesses were labor intensive.
A single, company-wide overhead rate based on direct labor hours
may be used to allocate overhead costs to products in these labor-
intensive processes.
Today, manufacturing processes are highly automated and direct
labor costs have become less significant.
Is it still appropriate to use direct labor hours to allocate overhead
costs?

Traditional Costing System
Advantages
Information is readily
available Easy to implement
Often sufficient to meet
external financial
reporting needs
Disadvantages
Overhead costs may
not bear anyrelationship with direct
labor hours
All products may not
use overhead costs inthe same proportion

1. Identify activities that consume resources.
2. Assign costs to a cost pool for each activity.
3. Identify cost drivers / cost allocation base
associated with each activity.4. Compute overhead rate for each cost pool:
5. Assign costs to products:

This result is not uncommon when ABC is used.
Many companies have found that low-volume, specialized products
have greater overhead costs than previously realized.

Semivariable Costs (Mixed Costs)
Mixed costs contain a fixed portion that isincurred even when facility is unused, and avariable portion that increases with usage.

Separating Semivariable Cost
Accounting records typically show only the total cost and theassociated amount of activity of a semivariable (mixed) costitem.
Separate mixed costs into their fixed and variable components
for cost estimation purposes. E.g. Budgeting, CVP analysis.
Methods: High-low Scattergraph method
Method of least squares (regression analysis) Managerial judgments

CVP for Decision Making
Cost-volume-profit (CVP) analysis is used to
answer questions such as:
How will income be affected if I increase selling
prices or reduce costs? (cost) What will happen to profitability if I expand
capacity? (volume)
How much must I sell to earn my desired income?
(profit) How will income be affected if I reduce selling
prices to increase sales volume?

CVP: Computing Break-Even Point
The break-even point (expressed in units ofproduct or dollars of sales) is the unique
sales level at which a company neither
earns a profit nor incurs a loss.

Margin of safety is the amount by which sales may
decline before reaching break-even sales:
The dollar amount by which Sales can decrease beforethe company incurs a loss.
