The variable cost ratio is a cost accounting tool 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 company’s net revenue includes the sum of its returns, allowances, and discounts subtracted from the total sales.
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 calculating 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.

It 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
The contribution margin is a quantitative expression of the difference between the company’s total sales revenue and the total variable costs of production of goods that were sold. The contribution margin is expressed in percentage points.
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%.
The variable cost ratio is an important factor in determining the overall profitability of a company. It indicates whether the business can 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 to determine necessary break-even or minimum profit margins, make profit projections, and identify 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 to cover the fixed costs involved in the production process. It just enables the company to stay in business without generating any substantial profits from sales.
