Variable Cost Ratio

A company’s variable production costs expressed as a percentage of its net sales

What is Variable Cost Ratio?

The variable cost ratio is a cost accounting tool that is used to express a company’s variable production costs as a percentage of its net sales. The ratio is calculated by dividing the variable costs by the net revenues of the company. The net revenue of the company includes the sum of its returns, allowances, and discounts subtracted from the total sales.

 

Variable Cost Ratio

 

The primary motive for calculating the variable cost ratio is to consider costs that may be subject to variations with changes in levels of production and compare them to the amount of revenues generated by the sales of that particular cycle of production.

In the calculation of the ratio, fixed costs, which are the expenses that remain constant regardless of variations in production levels, are excluded. Examples of fixed costs include building lease, employee salaries, etc.

 

Summary

  • The variable cost ratio is a cost accounting tool that it used to express a company’s variable production costs as a percentage of its net sales.
  • The primary motive of calculating the ratio is to consider costs that may be subject to variations with the changes in levels of production and to compare them to the amount of revenues generated by the sales of that particular cycle of production.
  • TIt is an important factor in determining the overall profitability of a company.

 

How to Calculate the Variable Cost Ratio

The formula for the calculation of the variable cost ratio is as follows:

 

Variable Cost Ratio = Variable Costs / Net Sales

 

An alternate formula is given below:

 

Variable Cost Ratio = 1 – Contribution Margin

 

Contribution margin is a quantitative expression of the difference between the total sales revenue of the company and the total variable costs of production of goods that were sold. The contribution margin is expressed in percentage points.

 

Sample Calculation

There are several ways in which the variable cost ratio can be calculated. Under the first method, the mathematical calculation is performed on a per-unit basis. In such a situation, consider a product with a per-unit variable cost of $10 and a per-unit sales price of $100. It gives a variable cost ratio of 0.1 or 10%.

The calculation can also be done by utilizing totals over a given period of time. Consider a situation wherein the total variable costs of production are $1,000 per month, and the total revenues generated per month are $10,000. The variable cost ratio, in this situation, is 0.1 or 10%.

 

Significance

The variable cost ratio is an important factor in determining the overall profitability of a company. It provides an indication of whether the business is able to achieve a desirable balance of revenue streams such that a rise in revenues is faster than that of expenses. It is used to express in quantitative terms the relationship shared by the sales of a company and the particular costs of production that are associated with the revenues being considered.

The ratio is a useful evaluation metric for a company’s management in determining necessary break-even or minimum profit margins, making profit projections, and identifying the optimal sales price for its products. In a situation where a company incurs high variable costs as a percentage of its net sales made, it is most likely that it does not need to cover a lot of fixed costs per month.

It means that the company will need to generate enough revenue such that it is able to cover fixed costs involved in the production process. It just enables the company to stay in business without generating any substantial profits from sales.
