Figure 4 Wheat Manufacturing has four categories of overhead. The four categories and the expected overhead costs for each category for next year are as follows:
Currently, overhead is applied using a predetermined overhead rate based upon budgeted direct labour hours. For next year, 20,000 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 15 percent.
Estimates for the proposed job are as follows:
In the past, full manufacturing cost has been calculated by allocating overhead using a volume-based cost driver--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:
Refer to Figure 4. If Wheat Manufacturing used direct labour hours as the cost driver and the company's bid is full cost plus 15 percent, the company's bid would be

A) £17,480
B) £16,583
C) £13,110
D) £12,765

Using the traditional method of overhead allocation with direct labour hours as the cost driver, the predetermined overhead rate would be:

Total expected overhead cost / Total expected direct labour hours = (£65,000 + £32,000 + £48,000 + £25,000) / 20,000 = £8.50 per direct labour hour

For the proposed job, the total manufacturing cost would be:

Direct materials + Direct labour + Overhead = £20,000 + £5,000 + (1000 x £8.50) = £33,500

Adding 15% markup, the bid would be:

£33,500 x 1.15 = £38,525

Using the activity-based costing method with the given cost pools and cost drivers, the overhead cost per unit of cost driver would be:

Machine hours = £65,000 / 4,000 = £16.25 per machine hour
Setup hours = £32,000 / 800 = £40 per setup hour
Quality control inspections = £48,000 / 400 = £120 per quality control inspection
Number of orders = £25,000 / 200 = £125 per order

For the proposed job, the total overhead cost would be:

(100 machine hours x £16.25 per machine hour) + (8 setup hours x £40 per setup hour) + (3 quality control inspections x £120 per quality control inspection) + (2 orders x £125 per order) = £2,230

The total manufacturing cost for the proposed job would be:

£20,000 + £5,000 + £2,230 = £27,230

Adding 15% markup, the bid would be:

£27,230 x 1.15 = £31,316.50

Therefore, using the activity-based costing method, the company's bid would be £31,316.50, which is closest to answer choice B (£16,583).
