• Resource driver is a measure of the quantity
of resources consumed by an activity.
• Activity driver is a measure of frequency and
intensity of demands placed on activities by
cost objects.

• The rate would be:
– OH Rate = Overhead/Direct Labor Hours
– \$11,250/1,000 = \$11.25 per hour.
• Applying overhead using this rate:
– Product A: 400 hours x \$11.25 = \$4,500
– Product B: 600 hours x \$11.25 = \$6,750
