Fundamentals of Cost Accounting and Production Systems

Cost Accounting Definition

Cost accounting is a system designed to determine, record, collect, distribute, monitor, analyze, and interpret information regarding production, distribution, and financing.

Purpose of Cost Accounting

• Assist in the strength and mechanisms of coordination between support areas.
• Determine unit costs.
• Generate information at levels that allow for better planning.
• Contribute to the development of budgets.

Cost and Expense Differentiation

The difference between these two lies in the role to which they are assigned. Costs are assigned to production functions, while expenses are assigned to administrative and distribution functions.

• Cost: This is the monetary value of the resources provided or promised to be delivered in exchange for goods or services purchased.
• Spending (Expense): This includes all expired costs that may be deducted from income. In a narrower sense, the word refers to expenditures on operating expenses (sales and administrative), interest, and taxes.

Classification of Costs

• Historical Costs: These are obtained after the product has been developed; they are costs that have been incurred, and their final amount is known after the fact.
• Default Costs: These help determine the selling price or measure the effectiveness of historical costs.

Cost Systems

A cost system is the set of procedures, techniques, records, and reports structured on the basis of double-entry theory principles and other techniques intended for the determination of the unit cost of production.

System Production Costs for Orders

This system collects costs for each order or lot that is physically identifiable as it passes through the production centers of the plant. The costs involved in processing a specified quantity of products, equipment, repairs, or other services are collected successively by identifiable elements: raw materials, direct labor, and overhead charges, which accumulate in a work order.

Characteristics of Order Cost Systems

1. Each element of cost is met separately.
2. Production is subdivided and categorized.
3. To start production, it is necessary to issue a work order.
4. Production examples include furniture, toys, and clothing.

The main objective is to control operational efficiency, making this system optimal for administrative purposes, planning, and cost control.

Process Cost System

This system is used in industries where final products are similar or identical. The cost is determined by dividing the total production costs by the units produced.

Stages and Definitions

• Stage Process: This is the transformation phase of the product.
• Incurred Costs: These are the costs within the production system (Raw Materials, Direct Labor, and Indirect Costs) applicable to the period.
• Finished Production in Process: This is represented by the physical volume that passes from one process to another during the period.
• Processed Production: This is the actual state of the process during the period, regardless of whether it is entirely concluded or not.
