Normally, setting up standards is based on the past experience. The total standard cost includes direct materials, direct labor and overheads. Normally, all these are fixed to some extent. The standards should be set up in a systematic way so that they are used as a tool for cost control.
Various Elements which Influence the Setting of Standards
Setting Standards for Direct Materials
There are several basic principles which ought to be appreciated in setting standards for direct materials. Generally, when you want to purchase some material what are the factors you consider. If material is used for a product, it is known as direct material. On the other hand, if the material cost cannot be assigned to the manufacturing of the product, it will be called indirect material. Therefore, it involves two things:
· Quality of material
· Price of the material
When you want to purchase material, the quality and size should be determined. The standard quality to be maintained should be decided. The quantity is determined by the production department. This department makes use of historical records, and an allowance for changing conditions will also be given for setting standards. A number of test runs may be undertaken on different days and under different situations, and an average of these results should be used for setting material quantity standards.
The second step in determining direct material cost will be a decision about the standard price. Material’s cost will be decided in consultation with the purchase department. The cost of purchasing and store keeping of materials should also be taken into consideration. The procedure for purchase of materials, minimum and maximum levels for various materials, discount policy and means of transport are the other factors which have bearing on the materials cost price. It includes the following:
· Cost of materials
· Ordering cost
· Carrying cost
The purpose should be to increase efficiency in procuring and store keeping of materials. The type of standard used-- ideal standard or expected standard-- also affects the choice of standard price.
Setting Direct Labor Cost
If you want to engage a labor force for manufacturing a product or a service for which you need to pay some amount, this is called wages. If the labor is engaged directly to produce the product, this is known as direct labor. The second largest amount of cost is of labor. The benefit derived from the workers can be assigned to a particular product or a process. If the wages paid to workers cannot be directly assigned to a particular product, these will be known as indirect wages. The time required for producing a product would be ascertained and labor should be properly graded. Different grades of workers will be paid different rates of wages. The times spent by different grades of workers for manufacturing a product should also be studied for deciding upon direct labor cost. The setting of standard for direct labor will be done basically on the following:
· Standard labor time for producing
· Labor rate per hour
Standard labor time indicates the time taken by different categories of labor force which are as under:
· Skilled labor
· Semi-skilled labor
· Unskilled labor
For setting a standard time for labor force, we normally take in to account previous experience, past performance records, test run result, work-study etc. The labor rate standard refers to the expected wage rates to be paid for different categories of workers. Past wage rates and demand and supply principle may not be a safe guide for determining standard labor rates. The anticipation of expected changes in labor rates will be an essential factor. In case there is an agreement with workers for payment of wages in the coming period, these rates should be used. If a premium or bonus scheme is in operation, then anticipated extra payments should also be included. Where a piece rate system is used, standard cost will be fixed per piece. The object of fixed standard labor time and labor rate is to device maximum efficiency in the use of labor.
Setting Standards of Overheads
The next important element comes under overheads. The very purpose of setting standard for overheads is to minimize the total cost. Standard overhead rates are computed by dividing overhead expenses by direct labor hours or units produced. The standard overhead cost is obtained by multiplying standard overhead rate by the labor hours spent or number of units produced. The determination of overhead rate involves three things:
· Determination of overheads
· Determination of labor hours or units manufactured
· Calculating overheads rate by dividing A by B
The overheads are classified into fixed overheads, variable overheads and semi-variable overheads. The fixed overheads remain the same irrespective of level of production, while variable overheads change in the proportion of production. The expenses increase or decrease with the increase or decrease in output. Semi-variable overheads are neither fixed nor variable. These overheads increase with the increase in production but the rate of increase will be less than the rate of increase in production. The division of overheads into fixed, variable and semi-variable categories will help in determining overheads.
