Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. This is related to an activity rate which is a similar calculation used in activity-based costing. A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead.
It is calculated as (overhead cost/ Labour hours required for production) if the labour hour required is 1000 and the overhead to be absorbed is 250 then the rate is .25 per labour hour. if 20 labour hours are required to complete a job then the overhead will be 5.
The Failures In Time (FIT) rate of a device is the number of failures that can be expected in one billion (10 9) device-hours of operation [17] (e.g. 1,000 devices for 1,000,000 hours, or 1,000,000 devices for 1,000 hours each, or some other combination).
Example: A given Work Center is scheduled to run for an 8-hour (480-minute) shift with a 30-minute scheduled break. Operating Time = 450 Min Scheduled – 60 Min Unscheduled Downtime = 390 Minutes The Standard Rate for the part being produced is 40 Units/Hour or 1.5 Minutes/Unit The Work Center produces 242 Total Units during the shift.
Following strong initial uptake, ABC lost ground in the 1990s compared to alternative metrics, such as Kaplan's balanced scorecard and economic value added.An independent 2008 report concluded that manually driven ABC was an inefficient use of resources: it was expensive and difficult to implement for small gains, and a poor value, and that alternative methods should be used.

Example: Two employees (workforce) are scheduled to work an 8-hour (480 minute) shift with a 30-minute scheduled break. Available Time = 960 min − 60 min break − 120 min Unscheduled Downtime = 780 Min The Standard Rate for the part being produced is 60 Units/Hour or 1 Minute/Unit The Workforce produces 700 Total Units during the shift.
