Answer:
(i) -62.5 (Unfavorable)
(ii) -450 (Unfavorable).
Explanation:
(1) Material variance:
Material cost variance is the difference between standard cost for actual output produced and the actual cost of materials.
Material cost variance = (SQ × SP) – (AQ × AP)
Where SQ = Standard quantity for actual output, AQ = Actual quantity, SP = Standard Price and AP = Actual price.
This material cost variance can be subdivided into material price variance and material usage variance.
Material price variance = AQ × (SP – AP)
Material usage variance = SP (SQ - AQ)
In the problem, it is given that materials 2 pounds @ 1.25 per pound.
Therefore, SP = $1.25 and SQ per unit = 2 pounds.
It is given that Glass vessel produced 300 vases using 650 pounds of material.
Therefore, AQ = 650 pounds and actual output = 300 vases.
Therefore SQ for actual output:
= (SQ per unit) × (Actual output)
= (2 pounds) × (300 vases)
= 600 pounds.
It is given that Glass vessel purchased 650 pounds of material for $845.
Therefore Actual price = $845 ÷ 650 pounds
= $ 1.3
SP = $1.25 and AP = $1.3
SQ = 600 pounds and AQ = 650 pounds.
Material cost variance = (SQ × SP) – (AQ × AP)
Material price variance = AQ × (SP – AP)
Material usage variance = SP × (SQ-AQ)
Material cost variance (MCV):
= (600 × 1.25) – (650 × 1.3)
= -95 (Unfavorable)
Material price variance (MPV):
= 650 × (1.25 – 1.3)
= -32.5 (Unfavorable)
Material usage variance (MUV):
= 1.25 (600-650)
= -62.5 (Unfavorable)
Verification:
MCV = MPV + MUV
= (-32.5) + (-62.5)
= -95.
(2) Labor variances:
Labor cost variance is the difference between standard labor cost and the actual cost.
Labor cost variance = (SH × SR) – (AH × AR)
Where SH = Standard hours for actual output, AH = Actual hours, SR = Standard rate and AR = Actual rate.
Labor cost variance can be subdivided into Labor rate variance and Labor efficiency variance.
Labor rate variance = AH × (SR-AR)
Labor efficiency variance = SR × (SH – AH)
It is given that Labor 1.5 hours @ $15 per hour is the standard.
Therefore, SR = $15 and SH per unit = 1.5 hours.
SH for actual output = SH per unit × actual output
= 1.5 × 300
= 450 hours.
It is given that the actual total labor costs for March were $7200, which entailed 480 hours of labor.
Therefore, AH = 480 hours.
AR = Labor cost ÷ labor hours
= 7,200 ÷ 480
= $15.
SH = 450 hours, AH = 480 hours, SR = $15 and AR = $15.
Here, standard rate and actual rate are same. Therefore the labor rate variance is NIL. So the entire labor variance will come under labor efficiency variance.
Labor cost variance = (SH × SR) – (AH × AR)
Labor rate variance = AH × (SR-AR)
Labor efficiency variance = SR × (SH – AH)
Labor cost variance = (450 × 15) – (480 × 15)
= -450 (Unfavorable)
Labor rate variance = 480 × (15-15)
= 0
Labor efficiency variance = 15 × (450 - 480)
= -450 (Unfavorable).
