Question

materials price variance for August.b. Compute the materials quantity variance for August.c. Compute the labor rate variance for August.d. Compute the labor efficiency variance for August.e. Compute the variable overhead rate variance for August.f. Compute the variable overhead efficiency variance for August.

What will be an ideal response?

Answer 1

a. Materials price variance = (AQ × AP) ? (AQ × SP)
= AQ × (AP ? SP)
= 48,100 grams × ($7.00 per gram ? $7.80 per gram)
= 48,100 grams × (-$0.80 per gram)
= $38,480 F

b. SQ = 6,300 units × 6.7 grams per unit = 42,210 grams
Materials quantity variance = (AQ × SP) ? (SQ × SP)
= (AQ ? SQ) × SP
= (42,200 grams ? 42,210 grams) × $7.80 per gram
= -10 grams × $7.80 per gram
= $78 F

c. Labor rate variance = (AH × AR) ? (AH × SR)
= AH × (AR ? SR)
= 1,350 hours × ($20.10 per hour ? $19.00 per hour)
= 1,350 hours × ($1.10 per hour)
= $1,485 U

d. SH = 6,300 units × 0.20 hours per unit = 1,260 hours
Labor efficiency variance = (AH × SR) - (SH × SR)
= (AH ? SH) × SR
= (1,350 hours ? 1,260 hours) × $19.00 per hour
= (90 hours) × $19.00 per hour
= $1,710 U

e. Variable overhead rate variance = (AH × AR) ? (AH × SR)
= AH × (AR ? SR)
= 1,350 hours × ($9.00 per hour ? $8.30 per hour)
= 1,350 hours × ($0.70 per hour)
= $945 U

f. SH = 6,300 units × 0.20 hours per unit = 1,260 hours
Variable overhead efficiency variance = (AH × SR) ? (SH × SR)
= (AH ? SH) × SR
= (1,350 hours ? 1,260 hours) × $8.30 per hour
= (90 hours) × $8.30 per hour
= $747 U
