# Labour Variances: Types and Their Formula

Decrease in overall wage rate resulting in favorable labor rate variance. By so doing, the full \$719,000 actually spent is fully accounted for in the records of Blue Rail. In manufacturing, efficiency variance can help managers analyze the effectiveness Comparison of Labor Price Variance vs. Labor Efficiency Variance of operations, with respect to labor, materials, machine time, and other factors. Calculate the direct materials usage variance, given the information above. Use the variance formulas to compute for the Variable-overhead spending variance.

• Calculate the cost of Job 845 using the plantwide overhead rate based on machinery hours.
• The comparison that is used to compute a labor variance compares standard versus actual rates and hours for workers, typically on a specific project.
• Another element this company and others must consider is a direct labor time variance.
• Where AQPis the actual quantity purchased, AP is the actual price and SP is the standard price.
• The overall labor variance could result from any combination of having paid laborers at rates equal to, above, or below standard rates, and using more or less direct labor hours than anticipated.
• Commonly used direct laborvariance formulasinclude the direct labor rate variance and the direct labor efficiency variance.

Following is an illustration showing the flow of fixed costs into the Factory Overhead account, and on to Work in Process and the related variances. But, a closer look reveals that overhead spending was quite favorable, while overhead efficiency was not so good. On the other hand, if actual inputs are less than the amounts theoretically required, then https://business-accounting.net/ there would be a positive efficiency variance. Since the baseline theoretical inputs are often calculated for the optimal conditions, a slightly negative efficiency variance is normally expected. Calculate the cost of Job 845 using the plantwide overhead rate based on machinery hours. Calculate the Fixed overhead spending variance for Desconins Ltd.

## What are common causes for labor variances?

As monies are spent on overhead (wages, utilization of supplies, etc.), the cost is transferred to the Factory Overhead account. As production occurs, overhead is applied/transferred to Work in Process . When more is spent than applied, the balance is transferred to variance accounts representing the unfavorable outcome. In this case, the actual rate per hour is \$7.50, the standard rate per hour is \$8.00, and the actual hour worked is 0.10 hours per box.

As mentioned above, materials, labor, and variable overhead consist of price and quantity/efficiency variances. Fixed overhead, however, includes a volume variance and a budget variance. For example, if the actual cost is lower than the standard cost for raw materials, assuming the same volume of materials, it would lead to a favorable price variance (i.e., cost savings). A negative value of direct labor rate variance is called favorable direct labor rate variance, which is the result of the actual rate being less than the standard rate. Each bottle has a standard labor cost of 1.5 hours at \$35.00 per hour.

## Direct Material Variances

Refer to the information in Exercise 21-8 and compute the direct labor rate and direct labor efficiency variances. Patty invented a virtually indestructible bicycle lock called Lastlock. The lock is lightweight, retractable, and fits easily in a jacket pocket. Sales of Lastlock skyrocketed when a local celebrity posted about Lastlock on social media. While the sudden increase in sales demand was exciting, Patty was not expecting the sudden increase in production so she experienced a number of production issues. In particular, she ran out of the alloy used to make Lastlock and was forced to purchase a lower quality batch from a different supplier. The lower quality batch; however, was significantly cheaper than her normal alloy.

Enter the number of direct labor hours budgeted, the number of direct hours actually worked, and the average hourly rate into the calculator to determine the labor efficiency variance. A positive value of direct labor rate variance is called unfavorable direct labor rate variance, which is the result of the actual rate being higher than the standard rate. A difference between the standard wage and actual wages paid during a certain period of time, denote the direct labor rate variance. The total direct labor variance was favorable \$8,600 (\$183,600 vs. \$175,000). However, detailed variance analysis is necessary to fully assess the nature of the labor variance. As will be shown, Blue Rail experienced a very favorable labor rate variance, but this was offset by significant unfavorable labor efficiency.

## 7 Direct Labor Variances

Although the new fabricator was less experienced, her pay rate per hour was lower. Since she paid less for the material and labor, Patty assumed that at the end of the period overall manufacturing costs would be lower than projected. However, manufacturing costs were higher than expected at the end of the period. Accordingly, Patty decided to perform a standard cost variance analysis on the manufacturing costs.
