What is the variable cost?

Variable Cost Definition

Variable costs are considered to be the total amount of all labor and materials that are needed to manufacture a unit of your product. This sum of variable cost is equivalent to the variable cost per unit, magnified by the number of units produced. Then, your variable cost will be averagely calculated as your total variable cost, divided by the number of units produced.

The variable costs can vary because they can increase and decrease as you make more or less of your product. If you can sell many units, so you can earn more money; however, a part of this money will need to be charged for the manufacturing cost to produce more units. Because you would have to need to make more units to turn your product into a profit at the same time you sell it. For each unit, it will require a specific level of resources, a greater number of units to increase necessary variable costs to produce them.

Variable Cost Examples

Let’s take the kitchenware maker selling business as an example. First, if you have someone purchased 10 knife sets for a total of 300 dollars, meanwhile, there are 100 dollars in the revenue budget that sent to craft the next 10 knife sets. So, when a business sells 30 knife sets for 900 dollars, which means that it has to pay 300 dollars of this revenue to make the next 30. On the whole, the kitchenware maker’s net revenue only increased by 100 dollars, while its variable costs increased by 300.

Total variable cost and average variable cost

A company’s total variable cost is defined as the expenses that vary in relation to the sum production during a given period. These costs are designed to connect to a business’ volume of production directly. They may fall up or down, relying on the amount of money that a company spends to produce. You can calculate the total variable cost by multiplying the cost to make one unit of your product by the number of products you’ve developed. For example, if it costs 70 dollars to make one unit of your product, and you’ve made 10 units, your total variable cost is 70 x 10, which is 700 dollars.

Meanwhile, the average variable cost is a different calculation that shows you the average cost to produce a single unit of a product by utilizing the total variable cost. The average variable cost is used for calculating the variable costs for each product that has varying costs per unit. To decide the average variable cost, you must know the variable cost of each unit being analyzed and then calculate the mean of them.

For instance, if you have 30 units of Product A at a variable cost of $20 for each unit, and 15 units of Product B at a variable cost of $50 for each unit, so there will be two different variable costs for you, which are $40 and $20. Additionally, you will have your average variable cost, which is (30 x $20 + 15 x $50) ÷ 45 , or $30 per unit.

Formula

For a specific period, you can utilize this formula to calculate the total variable cost for your company:

Total output quantity x variable cost of each output unit = total variable cost

To go more in details, to calculate your company’s total variable cost, you will have to follow the steps below:

  • First, clarify all variable costs that are associated with the production of every unit for your product. Cost of labor, cost of materials, and variable overhead costs are the most common elements to be considered in variable costs.
  • Secondly, you need to input all variable costs that are necessary to manufacture a unit together to obtain the total variable cost for one unit of your production.
  • Next, you will have to multiply the variable costs for each unit of a product by the total number of units produced. The sum of this calculation will give you the total variable cost.

Here are some of the most well-known costs to consider for determining the variable costs of production:

  • Production equipment, such as software
  • Shipment fees
  • Transaction costs
  • Production materials
  • Employee salaries
  • Sales commissions
  • Packaging fees

Examples

Let’s take a look at a real-life example of calculating total variable costs for the company’s production. There is a company that wants to regulate its total variable cost for producing 100 products. To calculate the total variable cost, of course, that company will have the figures for its variable cost per unit for each product manufacture first. For example, they will have to present:

  • Direct material fees for each unit: 10 dollars
  • Direct labor fees for each unit: 12 dollars
  • Overhead fees for each unit: 14 dollars

The variable costs to produce one unit is $10 + $12 + $14 = $36, so company must spend 37 dollars to produce a product. After that, the total variable cost to produce 200 units of product for that company will be decided according to the following formula: 200 x 36 = 7200, which means the total variable cost required to manufacture 200 units is 3600 dollars.
