Direct Labour Efficiency Variance

Definition

In a standard costing system, Direct Labour Efficiency Variance measures the efficiency of labour employed on production compared to preset standards. It reflects the difference arising between the actual hours worked and the standard hours allowed for the actual production output, evaluated at the standard direct labour rate. This variance indicates whether the labour force was more or less efficient than planned, influencing the overall profitability and cost control.

Formula

The formula for Direct Labour Efficiency Variance is:

\[ \text{Direct Labour Efficiency Variance} = (\text{Standard Hours} - \text{Actual Hours}) \times \text{Standard Rate} \]

Standard Hours (SH): The estimated hours required to produce the actual output.
Actual Hours (AH): The actual hours worked.
Standard Rate (SR): The predetermined direct labour rate per hour.

Examples

Positive (Favourable) Variance:
- Standard Hours for actual output: 500 hours
- Actual Hours worked: 480 hours
- Standard Labour Rate: $20/hour
\[ \text{Direct Labour Efficiency Variance} = (500 - 480) \times 20 = 20 \times 20 = $400 \text{ Favourable} \]
Negative (Adverse) Variance:
- Standard Hours for actual output: 500 hours
- Actual Hours worked: 520 hours
- Standard Labour Rate: $20/hour
\[ \text{Direct Labour Efficiency Variance} = (500 - 520) \times 20 = (-20) \times 20 = -$400 \text{ Adverse} \]

Frequently Asked Questions (FAQs)

What causes Direct Labour Efficiency Variance?

Direct Labour Efficiency Variance can be caused by a variety of factors:

Labour skill and productivity levels
Quality and efficiency of production processes
Adequacy of employee training and supervision
Workforce morale and motivation
Machine downtime or inefficiencies

Why is Direct Labour Efficiency Variance important?

This variance is critical for controlling costs and improving productivity. It helps managers identify areas where labour performance deviates from the standard and take corrective actions. It also impacts budgeting and financial planning by highlighting discrepancies between expected and actual labour costs.

How can Direct Labour Efficiency Variance be improved?

Improvement can be achieved through:

Enhanced worker training and more effective supervision
Streamlining production processes and reducing downtime
Motivating employees through performance incentives
Investing in better technology and equipment

Standard Costing:

An accounting method that uses standard costs to appraise performance by comparing them with actual costs.

Variance:

The difference between planned, budgeted or standard cost and actual cost.

Direct Labour Total Cost Variance:

The cumulative variance arising from the difference between actual direct labour cost and standard direct labour cost, including efficiency and rate variances.

Standard Direct Labour Rate:

The predetermined rate per hour for direct labour set in the budget.

Accounting Basics: “Direct Labour Efficiency Variance” Fundamentals Quiz

### What does the Direct Labour Efficiency Variance measure? - [ ] The number of workers employed - [ ] The cost of raw materials used - [x] The efficiency of labour hours compared to the standard - [ ] The overall production output quality > **Explanation:** Direct Labour Efficiency Variance measures the efficiency of labour hours compared to the standard hours allowed for production. It calculates the variance in cost using the standard labour rate. ### Which formula is used to calculate Direct Labour Efficiency Variance? - [ ] Actual Hours × Standard Rate - [x] (Standard Hours - Actual Hours) × Standard Rate - [ ] Standard Hours ÷ Actual Hours × Standard Rate - [ ] Total Production Cost ÷ Actual Hours > **Explanation:** The formula for Direct Labour Efficiency Variance is \$ (\text{Standard Hours} - \text{Actual Hours}) \times \text{Standard Rate} \$, highlighting the difference between standard and actual hours worked evaluated at the standard labour rate. ### What might cause a favourable Direct Labour Efficiency Variance? - [x] Higher than anticipated labour productivity - [ ] Increased absenteeism - [ ] Poor machine performance - [ ] Increased material wastage > **Explanation:** A favourable Direct Labour Efficiency Variance typically results from higher than anticipated labour productivity, where workers complete tasks faster than expected. ### How is a $500 favourable Direct Labour Efficiency Variance interpreted? - [ ] Labour was less efficient by $500 - [x] Labour was more efficient, saving $500 - [ ] The cost of materials decreased by $500 - [ ] Production volume increased by $500 > **Explanation:** A $500 favourable Direct Labour Efficiency Variance indicates that labour was more efficient than planned, resulting in savings of $500. ### In the formula for Direct Labour Efficiency Variance, the "Standard Rate" refers to what? - [ ] The actual wage rate paid - [ ] The overtime rate - [ ] The production output rate - [x] The predetermined rate per labour hour set in the budget > **Explanation:** The "Standard Rate" refers to the predetermined rate per labour hour set in the budget and is used to calculate labour variances. ### What impact does an adverse Direct Labour Efficiency Variance have on budgeting? - [x] Increases the budgeted labour costs - [ ] Reduces raw material usage - [ ] Enhances product quality - [ ] Lowers overall production output > **Explanation:** An adverse Direct Labour Efficiency Variance increases the budgeted labour costs because more hours were needed than standard hours, leading to higher than expected spending. ### When is a Direct Labour Efficiency Variance considered adverse? - [ ] Actual hours worked equal standard hours - [x] Actual hours worked exceed standard hours - [ ] Standard hours worked exceed actual hours - [ ] Production costs are less than budgeted costs > **Explanation:** A Direct Labour Efficiency Variance is adverse when the actual hours worked exceed the standard hours allocated for the production. ### What is one way to improve Direct Labour Efficiency Variance? - [ ] Increase the standard labour rate - [x] Enhance worker training and supervision - [ ] Increase the number of working hours - [ ] Reduce production output > **Explanation:** Improving worker training and supervision is an effective way to enhance labour productivity and improve Direct Labour Efficiency Variance. ### Why is it important to monitor Direct Labour Efficiency Variance? - [ ] To set wage rates - [ ] To calculate taxes - [x] To control costs and improve productivity - [ ] To determine loan eligibility > **Explanation:** Monitoring Direct Labour Efficiency Variance is crucial to control costs, identify inefficiencies, and improve overall productivity within the production process. ### Which factor does NOT influence Direct Labour Efficiency Variance? - [ ] Employee motivation - [ ] Machine downtime - [ ] Quality of raw materials - [x] Interest rates on loans > **Explanation:** Interest rates on loans do not directly influence Direct Labour Efficiency Variance. Instead, factors like employee motivation, machine downtime, and quality of raw materials play a significant role.
