Actual Variable overhead rate per hr = $170,000/(24000*2) =
$3.54 per hr
Actual FOH rate per hr = $450,000/(24000*2) = $9.38 per hr
Factory overhead volume variance represents the difference between
the budget allowance and the standard expenses charged to work in
process (standard hours allowed × standard overhead rate)
Factory overhead volume variance (FOHVV) = Budgeted allowance based
on standard hours allowed* – Overhead charged to production**
*Budgeted fixed expenses + variable expenses (standard hours
allowed for actual production × variable overhead rate)
**Standard hours allowed × Standard overhead rate
SO FOHVV =(24000*2*$9.38+ 2*24000* $3.54) -
($450000+2*24000*$3.50)
ie VV = $2,160 = $2160 U....... >ans(a)
The controllable variance is the difference between actual expenses
incurred and the budget allowance based on standard hours allowed
for work performed. This variance may be favorable or
unfavorable.
Controllable variance (CV) = Actual Factory Overhead (AFOH) -
Budgeted Allowance Based on Standard Hours Allowed (BFOH)
ie CV = ($450000+$170,000) - ($450,000+ 25000*2*$3.50) = $(5,000) =
$5000 F ..Ans(b)
Total factory overhead cost variance (TOHCV) is nothing but
Over/Under absorbed OHs
ie TOHCV = Total OH Cost absorbed - Total OH Cost incurred
ie TOHCV = Actula o/p *Budgeted rate pu -Actual o/p*Actual rate
pu
ie TOHPU = (24000*2*9.00 + 24000*2*$3.50) -
(24000*2*$9.38+24000*2*$3.54) = $(20,160)
ie TOHPU = $20,160 U ....ans(c)
2. Machine components are manufactured in a factory at a rate of about 80 per day....
