What is the Overhead Absorption Ratio (OAR) formula?

• A. Total budgeted overhead ÷ total budgeted activity
• B. Overhead absorbed ÷ actual activity
• C. Actual overhead ÷ budgeted activity
• D. Budgeted overhead ÷ actual activity

Answer: (A)

Overhead Absorption Rate is the rate used to allocate overhead to production based on the level of activity, and it is normally based on budgeted figures at the start of the period. The standard formula uses budgeted overhead divided by budgeted activity, giving a predetermined rate per unit of activity that can be applied consistently to units produced. This approach ensures the rate reflects planned resource use and provides a stable basis for costing, so overhead can be absorbed regardless of actual activity. Using actual data, or mixing actual with budgeted figures, would make the rate fluctuate or misalign with the intended costing model, which is why those alternatives aren’t the correct OAR.
