Understanding Overhead in Accounting
Understanding Overhead in Accounting
3. MACHINE HOURS
● A direct relationship between machine hours and
factory overhead cost is needed.
● This may occur in companies or departments that are
largely automated so that majority of the factory
overhead cost consists of depreciation of factory
equipment.
● The formula is:
a) Material Cost
b) Units of production
c) Machine Hours
OVERHEAD VARIANCE
1. With the use of actual costing:
ACTUAL OVERHEAD = APPLIED OVERHEAD
since actual amount of overhead is being applied to production
SAMPLE PROBLEM
Sharon Cuneta incurred the following costs of production during
the period:
● Direct Materials, 4,000 units @P56 per unit
● Indirect Materials, 1,000 units @P35 per unit
● Direct Labor, 9,600 labor hours @70 per DLH SAMPLE PROBLEM
● Indirect Labor, P96,400 At the start of the period, Halo Company still had inventories

P18,000. Overhead is applied at 120% of direct labor cost.
Compute for the following using normal costing:
1. Total manufacturing cost during the period
2. Work-in-process inventory, ending
3. Cost of goods manufactured

OVERHEAD VARIANCE
1. Overhead Variance is immaterial:
● The amount of variance is closed against
COGS
● If variance is Underapplied = COGS
Increases
● If variance is Overapplied = COGS
Decreases
2. Overhead Variance is material:
● The amount of variance is closed and
prorated against the accounts in which
applied overhead resides: WIP Inventory,
FG inventory, and COGS.

NOTE:
● Under GAAP, we need to use actual cost. Hence, we
adjust the COGS.
● Adjustment is only done at the end because we only get
the data of our actual overhead at the end of the
reporting period.

4. Sale of Goods:
ALLOCATION OF OVERHEAD
ALLOCATION OF OVERHEAD
APPORTIONMENT OF OVERHEAD
● Cost Apportionment is the allotment of proportions of
items to cost centers.
● When items of cost cannot be directly charged to or
accurately identifiable with any cost centers, they are
prorated or distributed amongst the cost centers on
some predetermined and suitable basis.
● Layman’s term: Apportionment of overhead costs
means to divide total cost of overhead among different
departments or branches or cost centers of a company
● This method of allocation makes it possible to assess
the department’s operational efficiency. If the internal
cost for a service is greater than the price charged by an
external supplier, the service department could be
considered for elimination.
● Examples:
○ Purchasing, personnel, warehousing,
maintenance departments.
1. Direct Method
● Is the most widely used method.
● This method ignores any service rendered by
one service department to another.
ALLOCATION vs. APPORTIONMENT ● It allocates each service department’s total
● Allocation deals with the whole items of cost and cost directly to the producing departments.
apportionment deals with proportion of items of cost.
● Allocation is direct process of departmentalization of
overheads, where as apportionment needs a suitable
basis for sub-division of the cost
● Whether a particular item of expense can be allocated
or apportioned does not depends on the nature of
expense, but depends on the relation with the cost
centre or cost unit to which it is to be charged

Producing Department
● These departments perform the primary purpose of the
company—to produce goods and services for
consumers.
● They are cost accumulation centers in which work is
performed directly on the goods being produced.
● Examples of operating departments are the assembly
departments of manufacturing firms and the
departments in hotels that take and confirm
reservations. 3. Algebraic/Reciprocal Method

Absorption of Overhead
● The ultimate aim of Overhead Accounting is to absorb
them in the product units produced by the firm.
● Thus, the indirect costs or overhead will have to be
distributed over the final products so that the charge is
complete.
● This process is known as cost absorption or
‘Absorption’ of overheads.
● FOH rate is used here!
C = 343,116.96
OH Variance is material
M = 152,710.62
When OH variance is material:
The amount of OH is closed and prorated against accounts in
which applied overhead resides: work-in process inventory,
finished goods inventory, and cost of goods sold.
