Estimate Fixed Overhead Variances
Referring to data, we can estimate the fixed overhead variances as given below:
Budget for December 2003;

Shs.

Fixed Overheads

11,480

Variable Overheads

13,120

Labour Hours

3,280 hours

Standard Hours of Production

3,280 hours

Actual Results for December 2003

Shs.

Fixed Overheads

12,100

Variable Overheads

13,930

Actual Labour Hours

3,150/hours

Standard Hours of Production

3,280 hours

Fixed Overhead Expenditure Variance is:
= Actual Fixed Overheads  Budgeted Fixed Overheads
= Shs.12,100  Shs.11,480 = Shs.620 (Unfavourable)
Fixed Overhead Capacity Variance is:
= Budgeted fixed Overheads  (Actual Hours x F.O. A. R)
= Shs.11,480  (3,150 x 3.5) = Shs.455 Unfavourable
Fixed Overhead Efficiency Variance is:
= (Actual Hours x F.O.A.R)  (Standard Production Hours x F.O.A.R)
= (3,150 X 3.5)  #,230 X 3.5) = Shs.280 Favourable.
Fixed Overhead Volume Variance is:
= Fixed Overhead Capacity Variance + Fixed Overhead Efficiency Variance.
= 455 (U) + 280 (F) = Shs.175 (Unfavourable)
Fixed Overhead Variance is:
= Fixed Overhead Expenditure Variance + Fixed Overhead Volume Variance
= Shs.620 (Unfavourable) + Shs.175 (Unfavourable)
= Shs.795 (Unfavourable).
The approach described so long is the most generally used especially for examination. Another cause that the student must be confident enough along with so long for further insights the student could proceed to the given section.
