What You’ll Learn

After completing this lesson, you will be able to:

  • Explain the purpose of variance analysis.
  • Identify significant budget variances.
  • Distinguish between favourable and unfavourable variances.
  • Investigate the causes of significant variances.
  • Recommend appropriate corrective actions.
  • Apply management by exception when reviewing organisational performance.

Overview

No budget will match actual financial performance perfectly. During every reporting period, organisations experience differences between planned results and actual results. These differences are known as variances.

Variance analysis enables management to understand why these differences occurred, determine whether they are significant and decide whether corrective action is required. Rather than simply identifying financial differences, effective variance analysis focuses on understanding their underlying causes so that future performance can be improved.

This lesson introduces variance analysis and explains how organisations investigate, report and respond to significant budget variances.

1. What is Variance Analysis?

Variance analysis is the process of comparing actual financial performance with planned or budgeted performance to identify differences.

Variance analysis helps organisations to:

  • Monitor financial performance.
  • Identify unexpected changes.
  • Understand why variances occurred.
  • Improve financial control.
  • Support management decision-making.
  • Strengthen future budgeting.

Rather than focusing only on the size of a variance, organisations should also investigate its underlying causes.

2. Why Variance Analysis is Important

Variance analysis provides valuable information that supports effective management.

It enables organisations to:

  • Detect financial problems early.
  • Improve budget accuracy.
  • Identify operational inefficiencies.
  • Evaluate management performance.
  • Improve future forecasts.
  • Support corrective action.

Regular variance analysis strengthens organisational financial control throughout the budgeting period.

3. Common Types of Variances

The learner guide identifies several common variances that organisations may monitor.

These include:

Purchase Price Variance

Measures differences between the actual and expected cost of purchased materials.

Labour Rate Variance

Measures differences between actual labour costs and planned labour costs.

Variable Overhead Spending Variance

Measures differences in variable overhead expenditure.

Fixed Overhead Spending Variance

Measures differences between actual and budgeted fixed overhead costs.

Selling Price Variance

Measures differences between actual selling prices and budgeted selling prices.

Material Yield Variance

Measures differences between expected and actual material usage.

Labour Efficiency Variance

Measures whether labour hours were used more or less efficiently than planned.

Variable Overhead Efficiency Variance

Measures efficiency in the use of resources associated with variable overheads.

4. Favourable and Unfavourable Variances

Not all variances are negative.

Favourable Variance

Occurs when financial performance is better than expected.

Examples include:

  • Revenue exceeds budget.
  • Costs are lower than expected.
  • Profit exceeds planned targets.

Unfavourable Variance

Occurs when performance falls below expectations.

Examples include:

  • Revenue below budget.
  • Costs higher than planned.
  • Lower profitability.

Understanding whether a variance is favourable or unfavourable helps management prioritise corrective action.

5. Investigating Significant Variances

Management should investigate variances that have a meaningful impact on organisational performance.

Possible causes include:

  • Changes in market conditions.
  • Increased supplier prices.
  • Ineffective management.
  • Unrealistic budgeting assumptions.
  • Operational inefficiencies.
  • Unexpected business events.

Understanding the root cause enables management to implement appropriate solutions.

6. Corrective Action

Once the cause has been identified, organisations should implement suitable corrective action.

Possible responses include:

  • Revising budgets.
  • Negotiating supplier prices.
  • Improving operational efficiency.
  • Strengthening cost control.
  • Updating financial forecasts.
  • Improving budgeting assumptions.

Corrective action helps prevent similar variances from recurring in future reporting periods.

7. Management by Exception

Many organisations apply the principle of management by exception.

Instead of investigating every small variance, management focuses on:

  • Significant favourable variances.
  • Significant unfavourable variances.
  • Variances indicating emerging financial risk.
  • Variances requiring immediate management action.

This approach allows managers to concentrate their efforts where they will have the greatest impact.

8. Reporting Variances

Variance reports should communicate information clearly and objectively.

A good variance report should include:

  • Budgeted amount.
  • Actual amount.
  • Size of the variance.
  • Whether the variance is favourable or unfavourable.
  • Cause of the variance.
  • Recommended corrective action.

Clear reporting enables management to make timely financial decisions.

Practical Example

A retail company budgeted R500,000 for inventory purchases during the quarter but spent R560,000.

During the variance investigation, management discovers that:

  • Supplier prices increased unexpectedly.
  • Demand was higher than forecast.
  • Additional stock purchases were required.

Management responds by:

  • Negotiating new supplier contracts.
  • Updating future budgets.
  • Revising inventory forecasts.
  • Monitoring purchasing costs more closely.

By analysing the variance rather than simply recording it, the organisation improves future budgeting accuracy.

Key Terms

Term Meaning
Variance Analysis The process of comparing actual performance with budgeted performance to identify and investigate differences.
Favourable Variance A variance that improves financial performance compared with the budget.
Unfavourable Variance A variance that reduces financial performance compared with the budget.
Labour Efficiency Variance A variance measuring the efficiency of labour usage compared with planned labour hours.
Management by Exception A management approach that focuses attention on significant variances requiring action.

Key Notes

  • Variance analysis compares actual performance with budgeted performance.
  • Organisations should investigate significant variances rather than every minor difference.
  • Variances may be favourable or unfavourable depending on their impact on financial performance.
  • Understanding the cause of a variance is more important than simply identifying it.
  • Corrective action improves future budgeting and financial performance.
  • Management by exception helps managers focus on the most important financial issues.
