Importance and Limitation of Sales Volume Variances


Sales volume variance is the difference between actual sales volume and budgeted sales volume during a specific time and multiply the resulted quantity with standard price.

This variance is calculated when management want to assess how to the actual sales volume affect the expected sales amounts at the standard sales price.

The company might has many different products and selling of some products were performance very well and sales of some of the products were not perform well during the period.

For the products that sold more than the plan, budget or expectation, then variance should be in favorable of management.

And for those products that the actual sales is below the plan, then the result will be unfavorable variance

Sales volume variance= (Expected sales volume – Actual sales volume) × Standard Rate

The formula for calculating sales quantity variance is simple and easy to understand.

  • Expected sales volume is the budget volume that management plan to sell in their business plan or budget plan.
  • Actual sales volume is the actual sale units that company sold during the period.
  • Standard rate of sales price is the price that company management set to sell at the beginning of the period.

Example to Understand the Concept:

Read the following example to understand the concept

Actual Sales Quantity = 50,000

Expected Sales Volume = 40,000

Standard Price = 20


The formula to calculate the quantity variance will be

Sales quantity variance= (Expected Quantity – Actual Quantity) × Standard Rate

Put the Values from the question

Sales quantity variance

= ($50,000-$40,000) × $20

= $20 × $10,000

=$200,000 Favorable

1) Importance of Sales Volume Variances:

Calculation of variances is as useful as any other report generated in any organization. It gives information about what was planned at the start and what was achieved during the period.

Sales volume variances is a management tool used to evaluate the performance of the sales team and make the necessary decisions.

2) Tool for Performance Evaluation:

4) Limitation of Sales Volume Variances:

The sales volume variance has some limitations, due to which the results may not be useful as it could be.

Companies always try their best to overcome these limitations, but due to limited resources or any other uncontrollable issue, they may not be able to fully overcome these limitations.

5) Mistakes in Planning:

While making budget estimations for the next periods, sometimes management ignores a lot of previous calculations.

This makes the budget estimation very unreal in nature, and when then you compare the budget with the actual data, you find a lot of unfavorable results.

So if you do not update your estimation time to time there is a great chance that you will not get the true picture of your business.

6) Difficulties in Obtaining Financial Data:

After the completion of the financial year, the organization takes a lot of time to gather and summarize all the financial data.

And you cannot compare the budgeted data with actual calculations until all the financial data get combined and organized in a form o report.

So when the actual data arises for analyses, there may be a time gap that may affect the usefulness of analyses.


The sales volume variances give all the information to the management which is necessary to make decisions.

The organization should consider all the factors which might affect the results of variance calculations.

Along with updated their estimations whenever they anticipate any major change in the course of business which will affect the product price.
