Solution
a) Direct Material Price Variance & Direct Material Quantity variance :-
i. Direct Material Price Variance =
It is the difference between the Standard Price and Actual Price for the Actual Quantity.
= [(SP-AP)*AQ]
Here
SP=standard price per unit
AP= actual price per unit
AQ=actual quantity of material consumed
.
= [(SP-AP)*AQ]
= [(2-1.95)*49200]
= 2460 Favorable .
ii.Direct Material Quantity variance=
It is the differebce between Standard Quantity specified for actual production and the Actual Quantity used , at Standard Price .
= [(SQ-AQ)*SP]
Here
SQ=standard Quantity
AQ=actual quantity of material consumed
SP=standard price per unit
.
= [(SQ-AQ)*SP]
=[(45000-49200)*2]
=(8400) Unfavorable
b) Direct Labour Rate Variance & Direct Labour Efficiency Variance:
i.Direct Labour Rate Variance=
It is the difference between standard rate per hour and actual rate , for actual hours .
= [(SR-AR)*AH]
Here
SR= Standard Rate per hour
AR= Actual Rate per hour
AH= Actual hours
.
= [(SR-AR)*AH]
=[(6-7)11800]
=(11800) Unfavorable
ii.Direct Labour Efficiency Variance=
It isthedifference between Standard hours for Actual production and Actual hours worked.
= [(SH-AH)*SR]
Here
SH= Standard hour for actual production
AH= Actual hours
SR= Standard Rate per hour
= [(SH-AH)*SR]
=[(12000-11800)*6]
=1200 Favorable
c) Variable Overhead Spending variance & Variable Overhead Efficiency variance=
i.Variable Overhead Spending variance =
It is the difference between budgeted variable overheads for actual hours and actual overheads incurred.
= (Budgeted Variable Overheads for actual hours) –(Actual Variable Overheads)
Here,
Standard Variable overhead Rate*Actual hours
.
= (SVohR*AH)-AVoh
=(3*5900)-18290
=17700-18290
=(590)Unfavorable
ii.Variable Overhead Efficiency variance =
It is difference between Standard variable Overhead and Budgeted Variable Overheads for Actual Hours.
=(SVohR*SH)-(SVohR*AH)
= [SvohR *(SH-AH)]
Here
SVohR=Standard Variable Overhead Rate
SH= Standard Machine Hours for production
AH= Actual Machine Hours for production
. Calculation for Standard Machine Hours
= SHper unit * no of units produced
= 0.4hr *15000
= 6000 hours
.
= [SvohR *(SH-AH)]
=[3*(6000-5900)]
= 1000 Favorable.
