Components of Standard Costs: Direct Materials, Direct Labour, and Overhead
In order to understand standard costing, it is important to have a clear understanding of the components that make up standard costs. Standard costs are predetermined costs that are set for each unit of production. These costs are based on the efficient use of resources and the optimal level of performance.
Direct Materials
One of the key components of standard costs is direct materials. Direct materials are the raw materials that are directly used in the production of a product. These materials can be easily traced to the final product and their costs can be easily determined. Examples of direct materials include steel, wood, plastic, and fabric.
When calculating standard costs for direct materials, it is important to consider two factors: price and usage. The price variance measures the difference between the standard price of the materials and the actual price paid for them. This variance can be either favourable or adverse, depending on whether the actual price is lower or higher than the standard price.
The usage variance, on the other hand, measures the difference between the standard quantity of materials that should have been used and the actual quantity used. This variance can also be either favourable or adverse, depending on whether the actual usage is lower or higher than the standard usage.
Direct Labour
Another important component of standard costs is direct labour. Direct labour refers to the cost of the labour that is directly involved in the production process. This includes the wages and benefits paid to the workers who are directly engaged in manufacturing the product.
Similar to direct materials, the standard costs for direct labour also consider two factors: rate and efficiency. The rate variance measures the difference between the standard labour rate and the actual labour rate. This variance can be either favourable or adverse, depending on whether the actual rate is lower or higher than the standard rate.
The efficiency variance, on the other hand, measures the difference between the standard labour hours that should have been used and the actual labour hours used. This variance can also be either favourable or adverse, depending on whether the actual efficiency is higher or lower than the standard efficiency.
Overhead
In addition to direct materials and direct labour, overhead costs are also included in standard costs. Overhead costs are the indirect costs that are incurred in the production process. These costs cannot be easily traced to a specific product or service.
Calculating standard costs for overhead can be more complex compared to direct materials and direct labour. However, it is important to consider the total fixed overhead variance, which measures the difference between the standard fixed overhead costs and the actual fixed overhead costs.
It is important to note that standard costs are based on predetermined standards and may not always reflect the actual costs incurred. However, they provide a benchmark for evaluating performance and identifying areas for improvement. By analysing the variances between standard costs and actual costs, organisations can identify inefficiencies and take corrective actions.
In conclusion, the components of standard costs include direct materials, direct labour, and overhead. Calculating variances for each component allows organisations to evaluate their performance and make necessary adjustments. While standard costs have their limitations, they provide valuable information for cost control, decision making, and inventory management.
