Chapter 10A - Predetermined overhead rates and overhead analysis in a standard costing system. After studying chapter Appendix 10A, you should be able to compute and interpret the fixed overhead budget and volume variances. | Appendix 10A Predetermined Overhead Rates and Overhead Analysis in a Standard Costing System Learning Objective 4 (Appendix 10A) Compute and interpret the fixed overhead budget and volume variances. Budget variance Fixed Overhead Budget Variance Budget variance Budgeted fixed overhead Actual fixed overhead = – Actual Fixed Overhead Fixed Overhead Applied Budgeted Fixed Overhead Volume variance Fixed Overhead Volume Variance Volume variance Fixed overhead applied to work in process Budgeted fixed overhead = – Actual Fixed Overhead Fixed Overhead Applied Budgeted Fixed Overhead FPOHR = Fixed portion of the predetermined overhead rate DH = Denominator hours SH = Standard hours allowed for actual output SH × FPOHR DH × FPOHR Fixed Overhead Volume Variance Volume variance FPOHR × (DH – SH) = Actual Fixed Overhead Fixed Overhead Applied Budgeted Fixed Overhead Volume variance Computing Fixed Overhead Variances Computing Fixed Overhead Variances Predetermined Overhead Rates Predetermined . | Appendix 10A Predetermined Overhead Rates and Overhead Analysis in a Standard Costing System Learning Objective 4 (Appendix 10A) Compute and interpret the fixed overhead budget and volume variances.
