Answer:
estimated overhead for the activity/estimated use of the cost driver for the activity
Explanation:
In case of the activity-based costing, the formula to compute the overhead rate is shown below:
Overhead rate = (Estimated overhead for the activity) ÷ (Estimated use of the cost driver for the activity)
The cost driver can be in machine hours, direct labor hours, etc and the overhead cost for the activity includes machine setup cost, machine running cost, etc
We simply divide the estimated overhead for the activity by the estimated use of the cost driver for the activity so the estimated overhead rate can arrive.
We considered the estimated overhead for the activity instead of the estimated overhead for the product
