A manufacturer uses process costing. It has one direct material cost pool and one conversion cost pool. Information for the month is as follows:
Beginning of Month End of Month
Work in process: 21,000 units 12,000 units
Conversion (% of completion in WIP): 35% 90%
Costs of Materials in WIP: $ 81,000 ?
Costs of Conversion in WIP: $113,000 ?
During the month:
Units started during the month: 70,000 units
Costs incurred for Materials: $280,000
Costs incurred for Conversion: $270,000
Sales: $920,000
Admin expenses $200,000
Other Information:
85% of direct materials is added at the beginning of the process, and the remaining 15% of direct materials (for packaging) are added at 95% completion.
Two assumption to make things a bit easier:
Required:
Part A: Calculate the total value of ending Work in Process and calculate Cost of Goods Sold, assuming that inventory is based on FIFO.
Part B: Calculate the total value of ending Work in Process and calculate Cost of Goods Sold, assuming that inventory is based on Weighted Average.
FIFO METHOD
step 1
determine physical unit to account for
| unit in beginning inventory | 21,000 | completed unit transferred out | 79,000 |
| + unit started during the period | 70,000 | + ending inventory unit | 12,000 |
| physical unit | 91,000 | 91,000 |
completed unit = beginning inventory + started during the period - ending inventory
step 2.
| material | conversion | |
| completed unit | 79,000 | 79,000 |
| + ending inventory | 10,200 (12,000 * 85% ) | 10800 (12000 * 90%) |
|
beginning inventory material 21000 * 85% conversion 21000 * 35% |
(17850) | ( 7350 ) |
| EFU ( FIFO ) | 71,350 | 82450 |
step 3.
determine total cost to be accounted for.
| material | conversion | |
| beginning inventory cost | 81,000 | 113,000 |
| period cost | 280,000 | 270,000 |
| total cost to accounted | 361,000 | 383,000 |
step 4
compute unit cost based on EFU denominator compute in step 3 (use both method )
material 280,000 / 71,350 = 3.92
conversion 270,000 / 82450 = 3.27
total unit cost = 7.19
step 5.
| from beginning inventory | ||
| beginning costs ( 81,000 + 113,000 ) | 194,000 | |
|
material add during period 21000 * 15% * 3.92 |
12,348 | |
|
conversion added to completed during period 21000 * 65% * 3.27 |
44635.5 | |
|
started and completed (started 70000 - 12000ending inventory ) 58000 * 7.19 |
417020 | |
| total costs transferred out | 668003.5 | |
| ending WIP | ||
| material 12000 * 85% * 3.92 | 39984 | |
| conversion 12000 * 35% * 3.27 | 13734 | |
| ending WIP COST | 53718 | |
| total cost account | 721721.5 |
weighted average method
step 1
determine physical unit to account for
| unit in beginning inventory | 21,000 | completed unit transferred out | 79,000 |
| + unit started during the period | 70,000 | + ending inventory unit | 12,000 |
| physical unit | 91,000 | 91,000 |
completed unit = beginning inventory + started during the period - ending inventory
step 2
compute equivalent finished unit
| material | conversion | |
| compete unit | 79,000 | 79,000 |
| + ending inventory | 10,200 (12000 *85%) | 10,800 (12000 * 90%) |
| EFU (weighted average ) | 89,200 | 89,800 |
step 3
determine total cost to be accounted for.
| material | conversion | |
| beginning inventory cost | 81,000 | 113,000 |
| period cost | 280,000 | 270,000 |
| total cost to accounted | 361,000 | 383,000 |
step 4.
compute unit costs based on EFU denominators in step 3
(use total cost )
material 361,000 / 89,200 = 4.04 per unit
conversion 383,000 / 89,800 = 4.26 per unit
total unit cost = 8.3
step 5. use unit cost computed in step 4 to allocate cost between units completed transferred out and units in ending inventory .
completed unit
| material | conversion | total cost | |
| complete unit 79,000 * 8.3 | 655,700 | ||
| ending inventory | |||
| material 12,000 * 85% * 4.04 | 41208 | 41,208 | |
| conversion 12000 * 90% * 4.26 | 46,008 | 46,008 | |
| total ending inventory | 87,216 | ||
| total cost accounted for | 742,916 |
