To calculate budgeted variable factory overhead cost
Indirect factory labour =46,000 / 20,000 hrs × 22,000 hrs
= $50,600
Power and light= 12,000/ 20,000 hrs × 22,000 hrs
=$13,200
Indirect materials = 20,000 / 20,000 × 22,000 hrs
= $22,000
To calculate fixed factory overhead rate
= $130,000/ 25,000hrs
= $5.20 per hour
To calculate favourable variance
50,600 - 49,700= ($900)
13,200 - 13,000 =($200)
To calculate Total controllable variance
(900 + 200) = ($1,100)
To calculate Net controllable variance unfavourable
2000 - 1,100 = 900
To calculate volume variance unfavourable
(25,000hrs - 22,000hrs ) × $5.20
= $15,600
To calculate Total Factory Overhead cost variance unfavourable
900 + 15,600
= $16,500
