What is a Mixed Cost? Definition, Formula, Example, and Importance

Mixed costs, also known as semi-variable costs, are business expenses that have both fixed and variable components. In simpler terms, it’s a cost that fluctuates according to the amount of production and cannot be eradicated like a fixed expense. The term “mixed cost” refers to the type of cost that contains both fixed and variable component. Given the inherent nature of mixed cost, it is also popularly known as semi-variable cost.

The variable component contains expenses that change with the production level, such as materials, labor, and energy (Bragg, 2019). Mixed costs are costs that contain a portion of both fixed and variable costs. Mixed costs (also called semi-variable costs) are costs that have both fixed and variable components. The fixed element doesn’t change with change in activity level at all and the variable component changes proportionately with activity. For example, if a company pays $1,000 in rent and $400 in utilities monthly, the total mixed cost is $1,400. In this case, rent is the fixed component, and utilities are variable (Bragg, 2019).

The formula above shows that the mixed cost has both components, which need to be added together to arrive at the total figure of the mixed costs. On the other hand, variable costs change with output and are directly correlated with the level of operation in the company. The company has to pay a fixed lease rental of $1,000 every month and it further incurs a running cost of $0.8 per km travelled. Determine the expense incurred during a month in which the car travelled 800kms. By understanding the fixed and variable elements of a mixed cost, managers can identify areas where costs can be reduced.

Mixed Costs Calculation: 3 Methods

A mixed cost can be bifurcated into fixed and variable elements using high-low method, scatter-graph method and least-squares regression. Hence, mixed costs can be defined as costs incurred by the company, which cannot strictly be classified as either fixed or variable. Mixed Costs can simply be defined as costs that include both fixed and variable components.

The more the employee sells the greater the sales commission expense becomes. The company can eliminate this expense altogether if it doesn’t sell anything for the month. Next, we will look at how we can estimate the fixed and variable portions of a mixed cost for accounting analysis. In a typical cellphone billing contract, a monthly flat rate is charged.

  • Therefore, they can best be described as costs that have a fixed component and a variable component.
  • For example, an executive may have a fixed salary but also be eligible for a variable annual bonus.
  • Mixed costs, a type of business expense, are comprised of fixed and variable elements.
  • A business experiences semi-variable costs in relation to the operation of fleet vehicles.
  • However, it’s possible to incur additional variable charges such as overage charges based on excessive bandwidth usage.

In some leasing situations, there is a base rent, and then a percentage of sales on top of the base. Let’s imagine that you rent a space for a small retail location in your local mall. The fixed portion of this expense is $500, because you pay that amount even if your sales are zero.

If you look at the graph above you can see how you apply this graph to our rent example. Semi-variable costs have both a fixed cost and a variable cost portion. Generally accepted accounting principles (GAAP) do not require a distinction between fixed and variable costs. These costs are not distinguished on a company’s financial statements. Therefore, a semi-variable cost may be classified into any expense account such as utility or rent, which will show up on the income statement. The analysis of semi-variable costs and its components is a managerial accounting function, for internal use only.

Examples of mixed costs include rent, insurance premiums, utilities, and more. They can be easily calculated by adding the fixed and variable components together. This graphical technique simplifies complex data into manageable visuals, allowing for easy analysis and understanding of financial information. By plotting activity levels across a graph, businesses can quickly identify which parts of their costs are fixed and variable. The y-axis measures the costs and the x-axis measures product or sales volume.

Therefore, they can best be described as costs that have a fixed component and a variable component. As far as fixed costs are concerned, it cannot be seen that they do not change with the level of output at which the company is operating. Therefore, the company incurred total expense of $1,640 for the car during the given month, wherein $1,000 is the fixed component and $640 is the variable component. The commission, on the other hand, acts more like a variable cost because it’s based on the productivity of the employee.

Going back to our example, the salary would be graphed like a fixed cost and the commissions would be graphed like a variable cost. The fixed portion of a semi-variable cost is incurred no matter the activity volume, while the variable portion occurs as a function of the activity volume. Management may analyze different activity levels by manipulating each one to change the variable costs.

These methods often require specialized expertise and can be time-consuming, adding complexity to the analysis process.

Merchandising Mixed Costs

The fixed component remains the same regardless of production or activity levels, whereas the variable component is more dynamic as it rises with increased output. For example, if a business how to process an invoice pays $1,000 in rent and $400 in utilities monthly, the total mixed cost is $1,400. In this case, the fixed component (rent) is $1,000, and the variable component (utilities) is $400.

Mixed costs contain two parts – a fixed cost component and a variable cost component. The proportion of each component in the total cost may vary depending on production volume. A semi-variable cost, also known as a semi-fixed cost or a mixed cost, is a cost composed of a mixture of both fixed and variable components. Costs are fixed for a set level of production or consumption, and they become variable after this production level is exceeded.


Determine the salary paid to John during the month of December 2019 if he could sell 2,000 units in that month. Some of the expenses are fixed because they do not change in total as the number of annual miles change. Some of the expenses are variable since the total amount will increase when more miles are driven and will decrease when fewer miles are driven. The variable expenses include gas, oil, tires, and some depreciation. A high-low-cost accounting method is an efficient approach to determining fixed and variable costs with limited data.

Mixed costs can be calculated by adding the fixed and variable components together. However, businesses may use other more complicated methods such as the high-low method, regression analysis, and scatter graph method. Generally, larger production volumes will result in a higher proportion of variable costs and vice versa. Examples of mixed costs include rent, insurance, management fees, salaries, salaries plus bonuses, and utilities.
