Definition:

A prime cost refers to a firm’s expense directly related to the materials and labor used in production. Prime costs are those costs that are directly incurred to create a product or a service and are particularly useful in determining the contribution margin of a product or a service and calculating the minimum price at which a product should be sold.

However, prime costs do not include overhead costs, so they are not good at calculating prices that ensure long-term profitability. It excludes all indirect expenses such as advertising and administrative costs.

More indirect costs such as utilities, manager salaries, and delivery costs are also excluded from prime costs. The production of goods and services involves many different kinds of expenses. Still, the prime cost formula only considers the variable expenses, which are directly connected to the production of each item.

Formula:

The formula used to calculate the prime cost is:

Prime Cost = Direct material + Direct labour

See the explanation below for the breakdown of this formula,

Explanation:

Direct material is the main component of prime cost and includes raw materials and supplies consumed directly during the production of goods.

Raw materials are the physical components, and during manufacturing, they might include metals, plastics, hardware, fabric, and paint. The types of raw materials vary depending on the nature of the business. For example, the raw materials might be lumber, hardware, and paint for a furniture manufacturer.

On the other hand, the other component of prime costs is direct labor, which includes wages paid to workers who directly contribute to forming, assembling, or creating a product.

It does not include salaries paid to factory managers or fees paid to engineers and designers. It only includes the wages that are directly related to the manufacturing of the product.

These employees are involved in the creation of the product and the day-to-day operation of the business. Moreover, commissions paid to salespeople who work as intermediaries between the manufacturer and the consumer also come under direct labor. Direct labor includes assembly line workers, welders, carpenters, glass workers, painters, and cooks.

Basically, the prime cost is the total sum of direct costs, which may be fixed or variable. Businesses use prime cost to measure the total cost of production inputs needed to create a given output.

By analyzing the prime costs, a company can set a price that will bring maximum profits. If a company cuts down its prime costs, it can increase its profits or undercut its competitor’s prices.

They need to calculate the prime cost of every product they have manufactured to generate a profit. Self-employed individuals often use prime costs to ensure that they are making their desired hourly wage while also profiting from every product they have made.

Businesses exclude indirect costs from the prime cost calculation because they can be tough to quantify and allocate. Prime costs also vary depending on the cost object being reviewed. If the cost object is a distribution channel, the prime cost will include the items specified and the direct costs of maintaining the distribution channel, such as marketing expenses.

However, if the cost object is a customer, prime costs can also include the cost of warranty claims, return processing, field servicing, and any staff assigned full time to service that customer.

Example:

For example, if a business manufactures 10 frames and incurs expenses such as $5,000 for lumber, $1500 for hardware, and 50 hours of labor for product assembly at a rate of $15 per hour, then only the costs of raw materials and direct labor are used in the prime cost formula.

The raw materials include $5,000 lumber and $1500 hardware, so the total cost of raw materials is $6,500.

The total labor cost is $750, which is calculated as 50 hours multiplied by $15 per hour. The prime cost of 10 frames is $7,250, and one frame is $725.
