A2CM-L05 — Material & Labour Variance Analysis
Understanding how material and labour variances are analysed to identify causes of inefficiency and improve business performance.
Learning Objectives
By the end of this lesson students should be able to:
• understand material variances
• understand labour variances
• calculate price and usage variances
• calculate rate and efficiency variances
• interpret variance results
• answer examination-style questions
Concept Framework
Why Analyse Variances?
A variance shows that actual performance differs from standard performance.
Management requires detailed variance analysis to determine:
• why variances occurred
• who is responsible
• whether corrective action is required
• how performance can be improved
Main Variance Categories
Material Variances
• Material Price Variance
• Material Usage Variance
Labour Variances
• Labour Rate Variance
• Labour Efficiency Variance
CORE TERMINOLOGY & FORMULAE Material Price Variance

INTERPRETING VARIANCES
| Variance | Possible Cause |
|---|---|
| Material Price Adverse | Higher supplier prices |
| Material Price Favourable | Discounts received |
| Material Usage Adverse | Waste or inefficiency |
| Material Usage Favourable | Efficient production |
| Labour Rate Adverse | Higher wage rates |
| Labour Rate Favourable | Lower labour costs |
| Labour Efficiency Adverse | Low productivity |
| Labour Efficiency Favourable | Efficient workforce |
Advantages
✓ Improves cost control
✓ Identifies inefficiencies
✓ Measures staff performance
✓ Improves purchasing decisions
✓ Supports management planning
Limitations
✓ May focus excessively on numerical results
✓ Variances may be caused by external factors
✓ Requires accurate standards
✓ Investigation can be costly
📌📌 Material and Labour Variance Analysis is among the most important examination topics in Cost & Management Accounting. Students should master: ✓ Variance Formulae ✓ Variance Calculations ✓ Variance Interpretation ✓ Management Recommendations ✓ Examination Presentation 🎥 Full worked solutions are available in the YouTube Learning Library. 📩 Students may submit variance analysis doubts through the Student Doubt Support facility.
Example 1 — Material Price Variance
Standard Price:
£4 per kg
Actual Price:
£5 per kg
Actual Quantity:
2,000 kg
Variance:(£4 − £5) × 2,000= £2,000 Adverse
Example 2 — Material Usage Variance
Standard Quantity:
1,800 kg
Actual Quantity:
2,000 kg
Standard Price:
£4Variance:(1,800 − 2,000) × £4= £800 Adverse
Example 3 — Labour Efficiency Variance
Standard Hours:
500
Actual Hours:
550
Standard Rate:
£10Variance:(500 − 550) × £10= £500 Adverse
