In the previous article difference between cost accounting and financial accounting is explained. When we talk about, cost accounting one thing strikes the mind of most of the people, i.e. classification of costs. Based on variability, the costs has been classified into three categories; they are fixed, variable and semi-variable.
Fixed costs, as its name suggests, is fixed in total i.e. irrespective of the number of output produced. Variable costs vary with the number of output produced. Semi-variable is the type of costs, which have the characteristics of both fixed costs and variable costs. Take a look at the article which explains the difference between fixed cost and variable cost in tabular form.
Content: Fixed Cost Vs Variable Cost
|Basis for Comparison||Fixed Cost||Variable Cost|
|Meaning||The cost which remains same, regardless of the volume produced, is known as fixed cost.||The cost which changes with the change in output is considered as a variable cost.|
|Nature||Time Related||Volume Related|
|Incurred when||Fixed costs are definite, they are incurred whether the units are produced or not.||Variable costs are incurred only when the units are produced.|
|Unit Cost||Fixed cost changes in unit, i.e. as the units produced increases, fixed cost per unit decreases and vice versa, so the fixed cost per unit is inversely proportional to the number of output produced.||Variable cost remains same, per unit.|
|Behavior||It remains constant for a given period of time.||It changes with the change in the output level.|
|Combination of||Fixed Production Overhead, Fixed Administration Overhead and Fixed Selling and Distribution Overhead.||Direct Material, Direct Labor, Direct Expenses, Variable Production Overhead, Variable Selling and Distribution Overhead.|
|Examples||Depreciation, Rent, Salary, Insurance, Tax etc.||Material Consumed, Wages, Commission on Sales, Packing Expenses, etc.|
Definition of Fixed Cost
The cost which remains constant at different levels of output produced by an enterprise is known as Fixed Cost. They are not affected by the momentary fluctuations in the activity levels of the organisation.
Fixed Cost remains constant does not mean that they are not going to change in future, but they tend to be fixed in the short run. This can be explained with an example, If your company is operating the business in a rented building, so whether you produce tons of output, or you produce nothing, you have to pay the rent of the building, so this is a fixed expense which is constant over a period until the rent of the building increases or decreases.
Fixed cost will be same in total but changes in per unit. To explain this, we have an example If the fixed cost is Rs. 10000 and the output produced in the first, second and third quarter are 4000, 5000 and 3000 units. Now, in this situation, what you can see is, the total fixed cost is unchanged in all the three-quarters, but the unit fixed cost in the first quarter is Rs. 10000/4000 units, i.e. Rs. 2.5, in the second quarter it is Rs. 10000/5000 units, i.e. Rs. 2 and in the third quarter it is Rs. 10000/3000 units, i.e. Rs. 3.33.
There are two types of Fixed Cost:
- Committed Fixed Cost
- Discretionary Fixed Cost
Definition of Variable Cost
The cost which changes with the changes in the quantity of output produced is known as Variable Cost. They are directly affected by the fluctuations in the activity levels of the enterprise.
Variable cost, varies with the variations in the volume, i.e. when there is an increase in the production, variable cost will also increase proportionately with the same percentage and when there is no production there will be no variable cost. The Variable cost is directly proportional to the units produced by the enterprise.
Now, variable cost remains same in per unit, but changes in total. You can understand this with an example, i.e. if the variable cost is Rs. 6 per unit and output produced in the first, second and third quarter is 5000, 6000 and 4000 units. You might wonder that the output level is changed in all the three-quarters, so the variable cost will also change, but only in the total amount but not in the unit price. So the variable cost in the first quarter is 5000*6 = Rs. 30000, in the second quarter it will be 6000*6 = Rs. 36000 while in the third quarter, it is 4000*6 = Rs. 24000.
The Variable cost is divided into two categories, they are:
- Direct Variable Cost
- Indirect Variable Cost
Key Differences Between Fixed Cost and Variable Cost
The following point are substantial, so far as the difference between fixed cost and variable cost in economics, is concerned:
- Fixed Cost is the cost which does not vary with the changes in the quantity of production units. Variable Cost is the cost which varies with the changes in the number of production units.
- The Fixed cost is time-related, i.e. it remains constant over a period. Unlike Variable Cost which is volume related, i.e. it changes with the change in volume.
- Fixed Cost is definite; it will incur even when there is no units are produced. Conversely, Variable Cost is not definite; it will incur only when the enterprise does some production.
- Fixed cost changes in per unit. On the other hand, variable cost remains constant in per unit.
- Examples of fixed cost are rent, tax, salary, depreciation, fees, duties, insurance, etc. Examples of variable cost are packing expenses, freight, material consumed, wages, etc.
- Fixed Cost was not included at the time of valuation of inventory, but Variable Cost is included.
Now, from the discussion mentioned above, it might be clear that the two costs are perfectly opposite to each other, and they are not same in any respect. There are many doubts while we talk about these two but with this article, you are surely going to be satisfied. So, this is all for the difference between Fixed Cost and Variable Cost.
