In the earlier article, much attention has been drawn on Prime Costs.

 

This article deals with

  • what are factory overheads,

 

  • how to treat Work-in-Progress in the Manufacturing Account and

 

  • finally showed a simple format of the Manufacturing and Trading Account of a manufacturing that buy goods from suppliers for resale and also manufacture some of its own goods for resale.

Looking at the below formula:

Cost of Production = Prime Costs + Factory Overheads

Therefore :

Factory Overheads = Cost of Production less Prime Costs

Hence, Factory Overheads Expenses:

  • are all expenses incurred by the factory over and above the prime cost and
  • do not relate directly to the actual production.

Normally, these includes:

  • Light and heat incurred in factory;
  • Power;
  • Depreciation of plant and machinery;
  • Rent and rates of factory;
  • Indirect labor costs like factory clerk’s salaries, factory manager’s salaries and production director’s remuneration

Take note that Factory Overheads do not include items like selling and distribution, administration and finance expenses.

 

WORK-IN-PROGRESS:

  • During the manufacturing process, there are often partly manufactured goods at the end of the accounting period. Such goods are usually valued according to the amount of materials, labor and expenses which have so far being incurred.

 

  • Treatment of Work-In-Progress:

To find the cost of production on completed goods, the work-in-progress at the beginning and end of an accounting period must be adjusted. This is by adding the opening work-in-progress to the cost of production and minus the closing work-in-progress ie:

 

Total cost of production                 XX

 

Add:

Work-In-Progress- 1 st June          xx

 

(Less:

Work-in-Progress- 30 th June       (xx)

Production costs of completed goods xx

 

Take note that sometimes work-in-progress  may be valued at prime cost which the adjustment would be to the total prime cost figure instead of total production cost figure.
