What do you mean by variances?

What do you mean by variances?

Definition: Variance can be defined as the difference between the budgeted or expected cost or income for an activity and the actual costs or income for the activity. In standard costing and budget control, variance constitutes the difference between the budgeted costs and the actual costs for an activity.

How do you explain variance analysis?

Definition: Variance analysis is the study of deviations of actual behaviour versus forecasted or planned behaviour in budgeting or management accounting. This is essentially concerned with how the difference of actual and planned behaviours indicates how business performance is being impacted.

What is the purpose of variance analysis?

Variance analysis is a method of assessing the difference between estimated budgets and actual numbers. It’s a quantitative method that helps to maintain better control over a business.

What are the two types of variances?

When effect of variance is concerned, there are two types of variances:

• When actual results are better than expected results given variance is described as favorable variance.
• When actual results are worse than expected results given variance is described as adverse variance, or unfavourable variance.

Can variance be positive?

A variance value of zero, though, indicates that all values within a set of numbers are identical. Every variance that isn’t zero is a positive number. A variance cannot be negative. That’s because it’s mathematically impossible since you can’t have a negative value resulting from a square.

What is the symbol for variance in statistics?

σ²

What is variance analysis and how is it used?

Variance analysis is the quantitative investigation of the difference between actual and planned behavior. This analysis is used to maintain control over a business. For example, if you budget for sales to be $10,000 and actual sales are $8,000, variance analysis yields a difference of $2,000.

How do you do cost variance analysis?

Steps of Cost Variance Analysis

1. Calculate the difference between what we spent and what we budgeted to spend.
2. Investigate why there is a difference.
3. Put the information together and talk to management.
4. Put together a plan to get costs more in line with the budget.

Why do companies calculate variances?

In project management, variance analysis helps maintain control over a project’s expenses by monitoring planned versus actual costs. Effective variance analysis can help a company spot trends, issues, opportunities and threats to short-term or long-term success.

Who is responsible for variances?

The materials price variance is usually the responsibility of the purchasing manager. The materials quantity and labor efficiency variances are usually the responsibility of production managers and supervisors.

What are the causes of material variance?

Following are the possible causes of this variance:

• Careless handling of materials by employees.
• Use of poor quality material.
• Poor maintenance and defects in machinery.
• Change in production design and production methods.
• Abnormal wastage.
• Pilferage of material due to inadequate inspection.
• Wrong mixture of materials.

Is positive variance good?

In theory, the positive variances are good news because they mean spending less than budgeted. The negative variance means spending more than the budget.

How do you find the positive variance?

You calculate the percent variance by subtracting the benchmark number from the new number and then dividing that result by the benchmark number. In this example, the calculation looks like this: (150-120)/120 = 25%. The Percent variance tells you that you sold 25 percent more widgets than yesterday.

What does a positive schedule variance mean?

If the Schedule Variance is positive, progress is ahead of schedule. If the Schedule Variance is negative, progress is behind schedule.

What does schedule variance tell you?

Schedule Variance (SV) indicates how much ahead or behind schedule the project is. It’s used by the Program Manager (PM) and program personnel to determine how best to utilize their remaining resources.

Why is schedule variance useful?

Schedule variance is an indicator of whether a project schedule is ahead or behind. It is typically used within earned value management (EVM) to provide a progress update for project managers at the point of analysis.

Is variance negative or positive?

Because the squared deviations are all positive numbers or zeroes, their smallest possible mean is zero. It can’t be negative. This average of the squared deviations is in fact variance. Therefore variance can’t be negative.
