Process Costing
- -a company produces many units of a single product
- - one unit of product is indistinguishable from other units of product
- - identical nature of each unit of product enables assigning the same average cost per unit
-
Examples of companies of Product Costing
- --Weyerhaeuser (paper manufacturing)
- -- Reynolds Aluminum (refining aluminum Ingots)
- -- Coca-Cola (mixing and bottling beverages)
-
Job Order Costing Characteristics
- -- many different products are produced each period
- -- Products are manufactured to order
- -- the unique nature of each order requires tracing or allocating costs to each job, and maintaning cost records for each job.
-
Example of companies that use Job-Order Costing
- -- Boeing (aircraft manufacturing)
- -- Walt Disney Studios (movie production)
- -- Bechtel International (large scale construction)
-
Predetermined Overhead Rate (POHR)
- estimated total MOH cost for the coming periodestimated total units in the allocation base for the coming period (direct labor hours)
-
Why should we use POHR
makes if possible to estimate total job costs sooner
-
Determining POHR
- -- estimate level of production for the period
- -- estimate total amount of the allocation base for the period
- -- estimate total manufacturing overhead costs
-
Schedule of Cost of Goods Manufactured
Beg. Raw Materials inventory + Purchase of raw materials = Total Raw Materials Available - Ending raw marterials inventory = Raw materials used in production - Indirect materials used in MOH + Direct labor + MOH applied in WIP inventory = Total Manufacturing cost + Beg WIP Inv. - End WIP Inv. = COGM
-
Schedule of Cost of Goods Sold
Beg. finished goods inv. + COGM = Goods available for sale - Ending finished goods inv. = Unadjusted COGS + Under/-Over applied Overhead = Adjusted COGS
-
Overhead Applied
POHR x Actual Activity
-
How do you find out if an item is over/under applied
Use Applied Overhead = POHR x Actual Direct Labor Hours
-
Underapplied Overhead
exists when the amount of overhead applied jobs during the period using the POHR is less than the total amount of overhead actually incurred during the period.
-
Overapplied Overhead
exists when the amount of overhead applied to jobs during the period using the POHR is greater than the total amount of overhead actually incurred during the period
-
What effect will the adjustment of the overapplied overhead have on net operating income
Net Operating Income will increase
-
What are the four levels used in cost Hierarchy
- -- Unit-Level
- -- Batch-Level
- -- Product Level
- -- Facility Level
-
How is Unit-Level used
- Activities includeprocessing units on machines, processing units by hand, consuming factory supplies
- Activitity Measuremachine-hours, direct labor hours, units produced
-
How is Batch-Level used
- Activities include
- processing purchase orders, processing production orders, setting up equipment, handling materials
- Activity Measure
- purchase orders processed, production orders processed, number of setups, pounds of material handled
-
How is Product level used
- Activities include
- testing new products, administering parts inventories, designing products
- Activity Measure
- hours of testing time, number of part types, hours of desing time
-
How is Facility- Level used
- Activities include
- general factory administration, plant building and grounds
- Activity Measure
- direct labor-hours, direct labor-hours
-
Computing Activity Rates
Estimated Overhead Cost / total expected activity
-
Computing Overhead Cost Per Unit
- Expected Activity x Activity Rate
- Add them all up and divide by the number of units produced
-
Finding the total Overhead Applied in an ABC System
Activity Rate x Actual Activity and add all the activities up
-
Formula for computing the cost per equivalent unit
- Cost of beg. Work in process inventory + cost added during the periodEquivalent units of production
- * do that for both Materials and Conversion and add them up
