Definition of Conversion Costs



Conversion costs are costs that are incurred on raw materials to transform them into finished goods. It includes direct labor costs and manufacturing overheads.

 


The formula for conversion cost is:

Conversion costs = Direct Labor cost + Manufacturing overheads

 


Direct labor costs are direct costs that are traceable and are allocated on an hourly basis. For example, a factory worker casts raw iron and transforms it into one steel bar in 30 minutes and is paid at a rate of $50 per hour. This is traceable for each unit of the steel bar.

 


 The worker works in a building that has a monthly rent of $5000. He also operates a press machine that consumes electricity of $6000 monthly and other maintenance costs of $1500. All these costs are not traceable and hence are allocated to each unit on a rate called FOH rate. Assume that per unit FOH cost is $35.00.

The total conversion cost for one steal bar will be:

  Conversion costs = ($50 x 0.5 labor hours) + $35.00 = $60.00 per unit
