What are unit costs?

Unit cost is a method of calculating the cost of producing one unit of a product or service. It can be used in various industries, including manufacturing and retail. Unit costs are typically expressed as a dollar amount per unit or can be calculated as a percentage of sales revenue.

Unit costs can be used to calculate many different financial metrics, including:

  • Cost of goods sold (COGS)
  • Break-even point (BEP)
  • Contribution margin

How do you calculate unit costs?

To calculate the unit cost, you need to take the average cost per unit and divide it by the number of units produced. The formula for calculating unit costs is:

Unit cost


Average cost per unit (ACPU)  ÷

Number of units produced

The ACPU can be determined by dividing the total cost of all items produced by their total number. For example, if you make 500 glass bottles at $1,000, your ACPU would be $2 ($1,000 divided by 500). When calculating unit costs using this method and assuming that each bottle requires 3 hours of labor at $10 per hour or raw materials costing $30 per pound, then each bottle has an ACPU of 49 cents per pound, which is outlined below:

Labor = ($10 × 3 hours) + ($30 ÷ 1 pound) = $40 + $9 = 49 cents per pound

Examples of unit costs

Below are a few common examples of unit costs:

  • Goods sold. The cost of goods sold is the total amount paid to acquire or manufacture a product. This includes direct materials and indirect costs such as freight.
  • Production. The production price includes all expenses for producing your product or service, including wages and salaries paid during this process and any other costs incurred (such as utilities).
  • Labor. Labor costs include all wages and salaries paid by your company during a given period, regardless of whether they were paid directly or indirectly through another company (e.g. if you outsource product design work). In addition to basic salary payments, this figure includes bonuses such as holiday payouts or commission payments depending on how much each employee earns per hour worked. It could vary significantly between individuals despite having similar job titles within one department.

Why are unit costs necessary for manufacturing?

Unit cost is essential for manufacturers because it helps determine the profitability of a product, the pricing of a product, and even the cost of production. It's also necessary to understand unit costs if you're going to calculate your company's gross margin (the percentage difference between the sales price and total cost).

What are the benefits of tracking unit costs?

Tracking unit costs benefits your business because it helps you make more informed decisions about pricing and production—you can use it to determine whether a price increase will be offset by higher sales volume or if increased production would be more profitable than raising prices.

For example, if you know that it costs $1 million per month to run your factory (including labor), but selling an extra ten units would generate an additional $300k in revenue, then it may make sense to increase production instead of raising prices.

Unit cost is an important metric to measure the profitability of products

Unit cost is important metric manufacturers use to measure the profitability of their products. Many factors can change the unit cost, including material prices and labor rates. Tracking these variables can provide valuable information to help you make better business decisions.
