Prime Costs vs Conversion Costs: What’s the Difference?

The cost of direct labor is included in both prime and conversion costs. Direct labor is a prime cost, a conversion costs, and a product cost. Pls noted that depreciation expenses, insurance expenses, maintnain expenses and electricity expenses are considered as manufactoruing overhead and we have to include all of these cost for our calculation with direct labor cots. TThese direct labor costs are the same ones used in calculating the prime cost in manufacturing.

Direct labor costs only comprise costs directly related to the workers who participated in the manufacture of completed items. For example, if a painter was hired to paint a car under construction, the painter’s salary would be included in the prime costs. The term conversion costs often appears in the calculation of the cost of an equivalent unit in a process costing system. Consider a professional furniture builder who is commissioned to build a coffee table for a customer. The primary costs for making the table include both the cost of the furniture maker’s labor and the raw materials needed to build the table, such as lumber, hardware, and paint. This refers to the costs that may be directly attributed to each unit of product or process.

The calculation of prime costs also assists firms in setting prices that create an acceptable amount of profit. Direct labor costs include the salaries, wages, and benefits paid to employees who work on the finished products. Compensation paid to machinists, painters, or welders is common in calculating prime costs. Prime costs and conversion costs include some of the same factors of production expenses, but each provides a different perspective when it comes to evaluating production efficiency. Increases in crude oil prices are likely to impact the costs of generating electricity which is significant in manufacturing costs.

For example, prime cost does not contain overhead charges that are applied in conversion cost. The prime cost’s major goal is to set the price of a product with the intended profits. The conversion cost, on the other hand, is estimated to total and resolve any production inefficiency. Although the prime cost is computed and given at the start of the cost sheet, there is a fixed standard that requires the computation of conversion cost until and unless the manager demands it.

Each department tracks its conversion costs in order to determine the quantity and cost per unit (see TBD; we discuss this concept in more detail later). In such cases, it is time-saving to calculate equivalent units and unit costs by combining direct labor and manufacturing overheads instead of doing separate calculations for the two cost items. Product costs consist of direct materials, direct labor, and factory overhead. Materials and labor together are prime costs, while labor and overhead are conversion costs. The true cost a company uses in the process of turning raw materials into finished goodsincludes both overhead and direct labor. Managerial accountants and production managers measure these conversion costs to estimate production expenses, develop product-pricing models, and estimate the value of finished inventory.

Thus, conversion costs are all manufacturing costs except for the cost of raw materials. Many of the same production characteristics are used by both conversion and prime cost, but each has a distinct perspective on product efficiency. To complete a product, prime cost includes both direct material and direct cost, whereas conversion cost does not.

For instance, the engine of a car and the spokes of a bicycle are considered direct material costs because they are necessary to complete the production of those items. Conversion costs are calculated in order to know the cost per unit, which assists the company in deciding a price for the product. Overhead costs are factored into a company’s conversion costs because they are required for the transition of raw resources into final costs. During a month, Company B spends $55,000 on direct labor and $66,000 on plant overhead.

  • ABC International incurs a total of $50,000 during March in direct labor and related costs, as well as $86,000 in factory overhead costs.
  • Factories must use electricity to power their machines and produce products, but each dollar of electrical costs can’t be directly tied back to the products that were produced.
  • Simultaneously, the prime cost is another costing phrase that quantifies the value of direct material, direct labor, and other direct expenses incurred in the manufacture of a certain product.
  • Prime costs are expenditures directly related to creating finished products, while conversion costs are expenses incurred when turning raw materials into a product.
  • Operations managers use conversion costs to help identify waste within the manufacturing process.

In other words, conversion costs are costs incurred by a manufacturer other than the cost of direct materials. Conversion cost is a costing word that describes the expenditures incurred in the form of direct labor and overhead to transform basic raw materials into completed items. Simultaneously, the prime cost is another costing phrase that quantifies the value of direct material, impairment of assets boundless accounting direct labor, and other direct expenses incurred in the manufacture of a certain product. They are used to measure the efficiency of a certain product’s production. The calculation for prime costs includes the amounts spent on direct materials and direct labor. Tangible components—such as raw materials—that are needed to create a finished product are included in direct materials.

What is Conversion Cost?

Conversion costs must be determined by each organization since they are critical for making significant business decisions and performing basic accounting procedures. It is calculated to determine the cost per unit, which aids the corporation in determining a price for the product. Operations managers use conversion costs to help identify waste within the manufacturing process. Suppose that the cost of the raw materials—lumber, hardware, and paint—totals $200. The furniture maker charges $50 per hour for labor, and the project takes three hours to complete. Prime costs are reviewed by operations managers to ensure that the company is maintaining an efficient production process.

Conversion costs are the sum of direct labor and manufacturing overheads. Examples of manufacturing overhead include the utilities, indirect labor, repairs and maintenance, depreciation, etc. that is occurring within a company’s manufacturing facilities. Conversion costs are the costs that are incurred by manufacturing companies when converting raw materials into finished goods. Prime costs and conversion costs are two methods that businesses use to measure the efficiency of their production operations.

A company’s accounts managers and production managers calculate these conversion costs to estimate the production expenses, and the value of the finished and unfinished inventory, and make product-pricing models. Direct labor is the cost of wages of factory employees who assemble the cabinets. Factory overhead includes expenditures for electricity and water bills, insurance premiums, roof repair, depreciation of machinery, materials used to build shelves in the factory, and wages of factory workers to assemble those shelves.

Which Costs Are Both Prime and Conversion Costs?

Conversion costs are also used as a way to measure the efficiencies in the production processes but they also take into account the overheads in the production process, which are not calculated in prime costs. Assume that direct materials cost $700, direct labor is $500, and factory overhead is $300 for cabinets that have been manufactured. This information helps managers know where to focus their attention when planning, directing and controlling costs.

The engine of a car, for example, and the spokes of a bicycle are both included in direct material costs. This is because they are both required to complete the production of that specific item. Hence, using conversion costs is an efficient way of calculating equivalent units and per unit costs rather than separately calculating direct labor and manufacturing overheads. Prime costs and conversion costs are relied upon heavily in the manufacturing sector to measure efficiency in the production of a product. Prime costs are expenditures directly related to creating finished products, while conversion costs are expenses incurred when turning raw materials into a product.

Conversion costs include the direct labor and overhead expenses incurred as raw materials are transformed into finished products. It is the direct labor plus any manufacturing overheads needed to convert raw materials into a finished product. Some of the same expenses are included in both prime costs and conversion costs. Prime costs and conversion costs, for example, will both include direct labor costs in their estimates. Like prime costs, conversion costs are used to gauge the efficiency of a production process, but conversion cost also takes into account overhead expenses that are left out of prime cost calculations.

An example of direct labor are the employees working on the assembly line of a manufacturer. It is rudimentary to gauge the value of closing inventory since it is a line item reported on both the income statement and the company’s balance sheet.

Prime Costs: Definition, Formula, Explanation, and Example

The manufacturing sector analyses both prime costs and conversion costs to measure efficiency in the production of a product. Consider a professional furniture maker who is hired to make a coffee table for a customer. The prime costs for creating the table include the cost of the furniture maker’s labor and the raw materials required to construct the table, including the lumber, hardware, and paint. These costs can’t be traced back to a single unit in the production process. Some other examples of manufacturing overheads are insurance, building maintenance, machine maintenance, taxes, equipment depreciation, machining, and inspection. Manufacturing overheads used in calculating conversion costs are the overheads that cannot be attributed to the production process or a single unit in production, for example, rent or electricity.
