QUESTION 4 Use the information provided below to calculate the following variances: • Raw material usage variance • Direct labour rate variance • Direct labour efficiency variance • Variable overheads efficiency variance. Note: Indicate whether each variance is favourable or unfavourable. INFORMATION The standards and actual information for product Zin produced by ABC Ltd are as follows: Standards: Material J Labour Variable overheads Normal production 4 kg @ $5 per kg 3 hours @ $30 per hour $11 per labour hour 10 000 units per month Actual information for October 2017: Material J used Labour Variable overheads Production 37 800 kg @ a total cost of $187 110 26 100 hours @ $31 per hour $12 per labour hour 9 000 units
Veriance | Formula | Calculation | Result | |
1 | Raw material usage variance | standared rare*(SQ-AQ) | 5$*(9,000*4kg -37,800kg) | 9,000U |
2 | Direct labour rate variance | Actual hours worked*(SR-AR) | 26,100hours*(30-31) | 26,100U |
3 | Direct labour efficiency variance | Standared rateof labour hour*(SH-AH) | 31$*(9,000units*3hours -26,100hours) | 27,900F |
4 | Variable overheads efficiency variance | Standared rate of VOH*(SH-AH) | 11$*(9,000units*3hours -26,100hours) | 9,900F |
F=favourable ,u= unfavourable,
SQ=STANDARED QUANTITY OF RAW MATERIAL REQUIRED FOR ACTUAL OUTPUT
AQ=ACTUAL QUANTITY OF RAW MATERIAL REQUIRED FOR ACTUAL OUTPUT
SH=STANDARED LABOUR HOURS REQUIRED FOR ACTUAL OUTPUT
AH=ACTUAL LABOUR HOURS REQUIRED FOR ACTUAL OUTPUT
