Plantwide Predetermined Overhead Rate
It is the overhead rate which normally uses direct labor hours as its base for allocating its total manufacturing overhead cost to jobs. It is calculated in two steps. First we need to calculate Total manufacturing overhead cost which is calculated using the equation:
Y = a + bx
Here:
Y = the estimated total manufacturing overhead cost
a = the estimated total fixed manufacturing overhead cost
b = the estimated variable manufacturing overhead cost per unit of the allocation base
X = the estimated total amount of the allocation base
The second step is calculation of predetermined overhead rate which is calculated as:
Predetermined Overhead Rate =
Estimated total manufacturing overhead cost / Estimated total amount of the allocation base
Calculation of Total manufacturing overhead cost
Calculation of Total manufacturing overhead cost (Y):
Estimated total fixed manufacturing overhead cost (a) = $28,600
Estimated variable manufacturing overhead cost per machine hour for Molding (b1) = $2.30
Machine hours required to support estimated production for Molding (X1) = 2,500
Estimated variable manufacturing overhead cost per machine hour for Fabrication (b2) - $3.10
Machine hours required to support estimated production for Fabrication (X2) - 1,500
Total manufacturing overhead cost (Y)
Y = a + b1 X1, + b2, X2,
Y = $28,600 + ($2.30x 2,500)+($3.10x1,500)
Y = $28,600+$5,750+$4,650
Y = $39,000
Total Manufacturing Overhead is $39,000
Calculation of Pre-determined Overhead Rate
It is calculated by dividing the estimated total manufacturing overhead cost by the estimated total amount of the allocation base.
Predetermined Overhead Rate
= Estimated total manufacturing overhead cost / Estimated total amount of the allocation base
= $39,000 / 4,000 = $9.75
The Pre-determined Overhead Rate is $9.75
