BASIC THEORIES

Methods of pricing the issues of materials

Materials issued against stores requisition are to be priced by the cost department before such issues are entered in the stores ledger and charged to a job or service. There are different methods of pricing the issues which may be enumerated as follows:

1.             Actual cost method (also known as specific cost method),

2.             First-In-First-Out (FIFO) method,

3.             Last-In-First-Out (LIFO) method,

4.             Simple average method,

5.             Weighted average method,

6.             Periodic simple average method,

7.             Periodic weighted average method,

8.             Moving simple average method,

9.             Moving weighted average method,

10.      Standard cost method.

 

1.       Actual cost method

Under this method, purchases made for particular jobs are kept physically separately in the store rooms and store cards are made out for the individual purchases. When materials are issued for jobs, requisitions are priced at the exact cost as recorded on the appropriate stores cards. This system is time consuming, but it is used effectively, when non-standardised items of materials have to be purchased to meet a customer’s specification. Some concerns operating on a job order basis use this method to price issues of materials that are not regularly kept in stock. Some other method is used to cost materials that are regularly used in production. This method does not have wide usage in big concerns due to basically the following two reasons:

(a)           This method is time consuming, and

(b)  This method is tedious in terms of record keeping.

 

2.       First-In-First-Out (FIFO) method

Under this method, for the purpose of pricing the issues it is assumed that the materials received first are consumed first. This is only an assumption for the purpose of taking rates for valuing issues. In actual practice, the pattern of cost flow may not necessarily coincide with the physical flow of the materials. FIFO method does not mean that the oldest materials are necessarily used first; in fact, the material received last may be issued first. It simply means that the oldest costs are used for accounting purposes first regardless of actual physical flow of materials. This method is ideally used where material is slow moving and has comparatively high unit cost.

 

3.       Last-In-First-Out (LIFO) method

Under this method, for the purpose of pricing the issues it is assumed that the materials received last are consumed first. This is only an assumption for the purpose of taking rates for valuing issues. In actual practice, the pattern of cost flow may not necessarily coincide with the physical flow of the materials. LIFO method does not mean that the latest materials are necessarily used first; in fact, the material received first may be issued first. It simply means that the latest costs are used for accounting purposes first regardless of actual physical flow of materials. This method works well in process cost systems where individual material requisitions are seldom used and materials move into process in bulk lots.


4.       Simple average method

Under this method, the different purchase prices of the materials in the stock, at the time of the issue for which the pricing is to be done, are added and then divided by the number of such purchases to obtain the simple average issue price. In short, a simple average of prices of lots available for issue is taken as the issue price. Any new purchase or exhaustion of any existing stock requires the issue price to be revised. The quantity of each purchase is ignored for the purpose of ascertaining the simple average issue price. It should be remembered that for deciding the possible lots out of which the issues could have been made, the method of FIFO is followed. The simple average method is particularly useful in the following circumstances:

(a)     When materials are received in uniform lot quantities.

(b)     When it is difficult to identify each issue of materials with the lots.

(c)     When purchase prices do not fluctuate considerably.

 

5.       Weighted average method

Under this method, the total value (at cost) of materials in stock at the time of issue is divided by the total quantity of materials in stock to obtain the weighted average issue price. Once a rate is worked out, it goes on being applied until a fresh purchase comes. This method is applicable when both purchase prices and order quantities fluctuate considerably.

 

6.       Periodic simple average method

Under this method, the rates of purchases during a given period are added and then divided by the number of such purchases during that period to obtain the periodic simple average issue price. Since the opening stock represents last period’s purchase, its value is not considered in the calculation of periodic simple average issue price. When this method is followed, the entire work of charging the issues has to be kept suspended till the end of the period when it is possible to calculate the periodic simple average issue price. This method can be successfully used in process industries.

 

7.       Periodic weighted average method

Under this method, the total cost of a material purchased during a given period is divided by the total quantity of the material purchased during that period to obtain the periodic weighted average issue price. Since the opening stock represents last period’s purchase, its value is not considered in the calculation of periodic weighted average issue price. When this method is followed, the entire work of charging the issues has to be kept suspended till the end of the period when it is possible to calculate the periodic weighted average issue price. This method can be successfully used in process industries.

 

8.       Moving simple average method

Under this method, the issue price is computed by dividing the total of the periodic simple average prices of a given number of periods by the number of periods. The moving simple average issue price so arrived at is used for pricing the issues made during the last of the above number of periods. This method is very useful when there are extreme fluctuations in material prices and the organisation desires to spread the total cost evenly over all goods.

 

9.       Moving weighted average method

Under this method, the issue price is calculated by taking the average of periodic weighted average prices, i.e. total of the periodic weighted average prices of a given number of periods is divided by the number of periods to obtain the moving weighted average issue price. The moving simple average issue price so arrived at is used for pricing the issues made during the last of the above number of periods. This method is very useful when there are extreme fluctuations in material prices and the organisation desires to spread the total cost evenly over all goods.

 

10. Standard cost method

Under this method, requisitions of materials are priced at standard cost. Standard cost is determined after careful consideration of different factors that are likely to affect cost. When standard cost is used as a basis for pricing the material issues, a standard price is set for each material and actual price is compared with the standard price. This method is very useful for management in determining the efficiency of efforts relating to material purchase, material issue and material usage, etc.

 

Important note:

As per Accounting Standard (AS) 2 w.r.t valuation of inventories, the cost of inventories should be assigned by using the first-in, first-out (FIFO), or weighted average cost formula. In other words, Stores Ledger Account should be prepared under the FIFO Method or Weighted Average Method of valuation of inventories and pricing the issues of materials to production. Accordingly, in this article I have illustrated these two methods of pricing the issues of materials to production along with two other popular methods which are Last-In, First-Out (LIFO) Method and Simple Average Method.

 

 

Stores ledger

The stores ledger is maintained by the costing department. It is usually kept in loose-leaf or card form so that they can be removed and inserted easily. Each account in the stores ledger represents an item of material. It is the most authentic record of stock value at any given point in time under different methods of pricing the issues of materials. The format of the stores ledger account which is same for all the different methods of pricing the issues of materials is as follows:

Treatment of shortage or surplus

If there are discrepancies arising between physical and book balances, the adjustment has to be done in the stores ledger. The shortage is shown as issue and is valued on the same basis as that of pricing of actual material issued. The surplus is treated as receipt at the latest purchase price just before the surplus is reported.

 

Valuation of returns to stores

When material is returned back from production department to the stores, the return is to be shown in the receipt column and the material should be taken back at the same price at which it was issued.

 

Valuation of returns to vendors

Materials which are not accepted for quality reasons or due to non-conformity to the specifications will be returned back to the vendor. If the defect is spotted during initial quality check, the materials are not taken in the stock ledger at all and returned as it is. If the materials are taken into stock, but not yet issued, the return is valued at the same price at which the receipt is recorded. If an issued material has to be returned back, firstly it is shown as a return from the production department to the stores and subsequently shown as a return to the vendor.
