Slide 6-5 Accounting for Factory Overhead Overhead Application (Overhead Absorption) Allocation of overhead costs to products Budgeted Factory Overhead Rate Calculated at the beginning of the year and used to apply overhead to products throughout the year Six Steps in Applying Overhead 1. Select a cost driver for overhead 2. Prepare a budget for yearly overhead costs and yearly volume of the cost driver 3.Calculate the budgeted factory overhead rate as Overhead rate = budgeted total overhead / budgeted cost driver 4. Obtain data on the actual cost driver 5. Apply overhead to products 6. At year end, account for difference between actual overhead costs and applied overhead costs

Slide 6-6 Over / Under Application of Overhead Actual overhead a mixed cost function with variable and fixed costs Y = F + VX Applied overhead a variable cost function Applied overhead = overhead rate x actual driver Overapplied: Applied > Actual Underapplied: Applied < Actual Dispose of over/under applied overhead at year end $ Volume Applied Overhead Actual Overhead Volume $ $

Slide 6-7 Fixed Manufacturing Overhead & Absorption Costing Firms use a overhead rate to smooth the application of overhead to work in process and determine "full" product costs Budgeted overhead =Budgeted total factory overhead application rateBudgeted total of cost driver difference between actual and applied fixed overhead relates to: spending more or less than expected producing more or less than expected Actual Fixed Overhead Budgeted Fixed Overhead Applied Fixed Overhead Rate x Actual Volume Fixed Overhead Spending VarianceProduction-Volume Variance Over / Under Applied Overhead
