Currently, overhead is applied using a predetermined overhead rate based upon budgeted direct labour
hours. For next year, 50,000 direct labour hours are budgeted.
The company has been asked to submit a bid for a proposed job. The plant manager feels that
obtaining this job would result in new business in future years. Usually bids are based upon full
manufacturing cost plus 30 per cent.
Estimates for the proposed job are as follows:
Direct labour (750 hours)
Number of materials moves
In the past, full manufacturing cost has been calculated by allocating overhead using a traditional
volume-based cost driver system—direct labour hours. The plant manager has heard of a new way of
applying overhead that uses cost pools and cost drivers.
Expected activity for the four activity-based cost drivers that would be used are as follows:
Determine the amount of overhead that would be allocated to the proposed job if direct
labour hours are used as the traditional volume-based cost driver.
Determine the total cost of the proposed job.
Determine the company’s bid if the bid is based upon full manufacturing cost plus 30 per
cent.
Determine the amount of overhead that would be applied to the proposed job if
activity-based costing is used.
Determine the total cost of the proposed job if activity-based costing is used.
Determine the company’s bid if activity-based costing is used and the bid is based upon full
manufacturing cost plus 30 per cent.
Which product costing method produces the more competitive bid?
a.
£5,250 (£140,000 + £60,000 + £50,000 + £100,000)/50,000 = £7 per DLH
£7 750 DLH = £5,250
£17,750 £5,000 + £7,500 + £5,250
£23,075 £17,750 130%
b.
£2,882.50
Maintenance: £140,000/16,000 = £8.75 per machine hour
Materials handling: £60,000/4,000 = £15 per move
Setups: £50,000/2,000 = £25 per setup
Inspection: £100,000/8,000 = £12.50 per inspection
