Answer:
1) No of hours required for 120,000 items= 120,000 *0.02= 2400 hrs
Variable overhead rate is $3.25 per direct labor-hour = 3.25*2400=$ 7800
Difference from Actual Variable overhead incurred = $ 7360 - $ 7800= $ 440
2) Number of items shipped . 120,000
Standard direct labor-hours per item 0.02
Total direct labor-hours allowed = 120,000 * 0.02= 2400
Standard variable overhead cost per hour $3.25
Total standard variable overhead cost = $ 7800
Actual variable overhead cost incurred = $7360
Total standard variable overhead cost (above) .. $7800
Total variable overhead variance = $7800- $7360= $440
Actual Hours of
Input, at the Actual Rate (AHxAR)
2300 hours x 3.2 per hour=$7,360
Actual Hours of Input at the Standard Rate
(AH x SR)
2300 hours x $ 3.25 per hour=$ 7475
Standard Hours Allowed for output at the standard rate
(SH x SR)
2400 Hours x 3.25 per hour=$ 7800
Variable Overhead Rate Variance =
Actual Factory Overhead -Variable Expense for Standard Hours
=$7360-$ 7475= $ 115
Variable Overhead Efficiency Variance = (AH x SR)-(SH x SR) =$ 7475-$ 7800= $325
Total Variance= Actual Overhead - (SR x SH)= $ 7360- $7800= $440 Favourable
$????/ ???? hour
$ 440/2400= $ 0.183 per standard direct labor hour
Alternatively, the variances can be computed using the formulas:
Spending Variance = Actual Factory Overhead- Budget allowance for Actual Hours
Variable Efficiency variance=Budget allowance for Actual Hours-Budget allowance for Standard Hours
