Codification of Overheads

Codification is a process of representing each item by a number, the digits of which indicate the group, the subgroup, the type and the dimension of the item.  It is always advisable to codify the overhead expenses. Codification helps in easy identification of different items of overheads. There are numerous items of overheads and a code number to each one will facilitate identification of these items easily. Codification can be done by allotting numerical codes or alphabetical codes or a combination of both. Whatever system is followed, it should be remembered that the system is simple for understanding and easy to implement without any unnecessary complications.

Objectives of Codification:

The main objectives of codification of overheads are:

1. To group items of overheads of similar nature as these may be apportioned using the same basis.

2. Decimal Codes Method. 
3. Codes with a Combination of Numbers and Alphabets. 

1. Numerical Method: Under this method, numerical codes are assigned to each item of expenses. For example,

100 Indirect labour.

400 Power.

500 Maintenance.

800 Fixed charges.

2. Decimal Codes: Under this method, the whole numbers are allotted to indicate master group and the decimals indicate the sub-group. For example,

Factory Overheads:

1.1.1 Indirect materials.

1.1.2 Consumable stores.

1.1.3 Lubricating oils.

3. Codes with a Combination of Numbers and Alphabet: Under this method the alphabet indicates the main group and the type of expenses is indicated by the numerical. For example,

R1 - Repairs to machinery.

R2 - Repairs to plant.

R3 - Repairs to furniture.
