Respuesta :
The preparation of reports showing the various required variances (total materials variance, the price and quantity materials variances, the total labor variance, and the labor price and quantity variances) are as follows:
a) The total materials Variance
= $1,400 Favourable ($104,000 - 102,600)
b) The Price and Quantity of Materials Variance:
1) Price of Materials Variance:
= $5,400 Favorable ($4.00 - $3.80) x 27,000
2) Quantity of Materials Variance:
= $4,000 Unfavorable (26,000 - 27,000) x $4.00
c) The total Labour Variance
= $8,050 Unfavorable ($30 - $30.805) x 10,500
d) The Labour price and quantity Variance
1) Labor Price Variance
= $3,050 Unfavorable ($10 - $10.10) x 30,500
2) Labor Quantity Variance
= $5,000 Unfavorable (30,000 - 30,500) x $10
What variance analysis?
In cost accounting, variance analysis investigates the differences between actual costs and budgeted costs of materials, labor, and overhead.
Variance analysis helps management to take corrective actions after identifying the causes.
Data and Calculations:
Standard material cost for Product A = 2 pounds
Standard cost per pound = $4.00
Standard cost per unit = $8 ($4.00 x 2)
Total standard cost for materials = $104,000 ($8 x 13,000)
Purchase of materials = 27,000 pounds
Cost per pound = $3.80
Total purchase cost for materials = $102,600 ($3.80 x 27,000)
Production units = 13,000 units
Actal materials used per unit = 2.0769 pounds (27,000/13,000)
Actual cost per unit = $7.89 ($102,600/13,000)
Standard labor cost per unit = 3 hours
Standard rate of pay = $10
Standard labor cost per unit = $30 (3 x $10)
Totall standard labor hours = 30,000 (3 x 10,000)
Actual labor hours incurred = 30,500 hours
Labor rate per hour = $10.10
Total labor costs = $308,050 (30,500 x $10.10)
Production units = 10,000 units
Actual labor cost per unit = $30.805 ($308,050/10,000)
