# Accounting Assignment Help With Costing Process

## Costing Process

Costing process starts with raw materials input and ends with finding cost of sales ( see figure 1.1)

### 5.1: Cost Determination Process

Let us take an example

A factory purchased 100000 units of raw materials @ \$10. it incurs wages \$6,75,000 and factory overheads \$3,00,000. its stock option position is as follows:

 Opening stock Closing stock Units \$ Units \$ Raw Material 4000 38000 5000 ? W-I-P 2000 30000 100 ? Finished Goods 1000 18000 1500 ?

Selling & Distribution overheads \$ 1,00,000

Find out cost of sales per unit.

Follow FIFO for valuation of raw material stock and average cost for W-i-P and finished goods.

Solution.

 Units \$ \$ Opening stock> 4,000 38,000 Purchases 1,00,000 10,00,000 1,04,000 10,38,000 Less closing stock 5,000 50,000 99,000 9,88,000 Direct Wages 6,75,000 Prime cost 16,63,000 Add Factory overheads 3,00,000 Factory Cost 19,63,000 Add opening WIP 2,000 30,000 Less Closing WIP (1,000) (19,733) 1,00,000 19,73,267 Add opening stock of finished goods 1,000 18,000 Less closing stock of finished goods (1,500) (29,573) Cost of goods sold 99,500 > 19,61,694 Add Admn. overheads 2,50,000 Add S&D Overheads 1,00,000 Cost of Sales 99,500 23,11,694

Cost of sales per unit is \$23.23

Notes: Valuation of closing stock

1. Closing stock of raw materials

By FIFO assumption items used first are issued first. So closing stock is valued @\$10 which is the latest purchase price.

2. Closing Stock of WIP

This is valued on average basis.

Total units including opening WIP 1,01,000

Total cost including value of opening WIP (\$19,63,000 + \$30,000) = \$ 19,93,000

Cost of WIP 1000 units = 19,93,000/1,01,000*1000 = \$ 19,733

3. Closing stock of finished goods on average cost basis.

Total units including opening cost 1,01,000

Total Cost including value of opening stock \$ 19,91,267

Cost of finished goods = 19,91,267/1,01,000*1500 = \$ 29,573
