Product Costing
Job Order
Allocate costs to productsthat are readily identifiable
Common in construction,print shops, unique goods
Accumulate costs forspecific jobs
Produce for sale
Process Costing
Average costs over large number of nearly identical units
Common in chemical, textiles, lumber, glass, food processing
Accumulate costs by departments
Produce for inventory

Job-Costing Cost Flows• Apply material, labour and overhead costs to work in process • As goods as produced costs flow to finished goods inventory • When sold, costs shift to cost of goods sold

Accounting for Factory Overhead Overhead Application (Overhead Absorption) • Allocation of overhead costs to products
Budgeted Factory Overhead Rate• Calculated at the beginning of the year and used to apply overhead
to products throughout the year
Six Steps in Applying Overhead
1. Select a cost driver for overhead2. Prepare a budget for yearly overhead costs and yearly volume of the
cost driver3. Calculate the budgeted factory overhead rate as
Overhead rate = budgeted total overhead / budgeted cost driver4. Obtain data on the actual cost driver5. Apply overhead to products 6. At year end, account for difference between actual overhead costs
and applied overhead costs

Over / Under Application of Overhead
Actual overhead• a mixed cost function with variable and fixed costs• Y = F + VX
Applied overhead• a variable cost function• Applied overhead = overhead rate x actual driver
• Overapplied: Applied > Actual • Underapplied: Applied < Actual • Dispose of over/under applied
overhead at year end

Fixed Manufacturing Overhead & Absorption Costing
• Firms use a overhead rate to smooth the application of overhead to work in process and determine "full" product costs
Budgeted overhead = Budgeted total factory overheadapplication rate Budgeted total of cost driver
• difference between actual and applied fixed overhead relates to:• spending more or less than expected• producing more or less than expected

Production Volume Variance in Absorption Costing
• Change in net income due to not producing the amount of output expected when we determined the P.O.R. at the beginning of the year
Production = Actual - Expected x BudgetedVolume Variance volume volume overhead rate
