Variable overhead efficiency variance is one of the two components of total variable overhead variance, the other being variable overhead spending variance. Jerry (president and owner), Tom (sales manager), Lynn(production manager), and Michelle (treasurer and controller) wereat the meeting described at the opening of this chapter. Michellewas asked to find out why direct labor and direct materials costswere higher than budgeted, even after factoring in the 5 percentincrease in sales over the initial budget. Lynn was surprised tolearn that direct labor and direct materials costs were so high,particularly since actual materials used and actual direct laborhours worked were below budget. A cost driver, typically the production units, drives the variable component of manufacturing overhead.
- During the year, the company spends 200,000 hours producing 35,000 of output.
- Actual manufacturing data are collected after the period under consideration is finished.
- To arrive at the total cost per unit, we need to multiply the unit of material and labor with the standard rate.
- If the actual rate of pay per hour is less than the standard rate of pay per hour, the variance will be a favorable variance.
- The actual results show that the packing department worked 2200 hours while 1000 kinds of cotton were packed.
Total direct material variance

Any variances between standard and actual costs are caused by a difference in quantity or a difference in price. Therefore, the total variance for direct materials is separated into the direct materials quantity variance and the direct materials price variance. The template provided in Exhibit 8-3 can be used to compute the total direct material variance, direct material quantity variance, and direct material price variance. In this case, the actual hours worked per box are 0.20, the standard hours per box are 0.10, and the standard rate per hour is $8.00. This is an unfavorable outcome because the actual hours worked were more than the standard hours expected per box.
How to Solve Unfavorable Variance?
If the actual hours worked are less than the standard hours at the actual production output level, the variance will be a favorable variance. A favorable outcome means you used fewer hours than anticipated to make the actual number of production units. If, however, the actual hours worked are greater than the standard hours at the actual production output level, the variance will be unfavorable. An unfavorable outcome means you used more hours than anticipated to make the actual number of production units. If the actual rate of pay per hour is less than the standard rate of pay per hour, the variance will be a favorable variance.
What is your current financial priority?
For example, an investigation could reveal that the company had to pay a higher rate to attract employees, so the standard hourly direct labor rate needs to be adjusted. Standard costs are established for all direct labor used in the manufacturing process. Direct labor is considered manufacturing labor costs that can be easily and economically traced to the production of the product. For example, the direct labor necessary to produce a wood desk might include the wages paid to the assembly line workers. Indirect labor is labor used in the production process that is not easily and economically traced to a particular product.
He estimates that each unit should require 4.2 feet of flat nylon cord that costs $0.50 per foot for total direct material costs per unit of $2.10. Each unit should require 0.25 direct labor hours to assemble at an average rate of $18 per hour for total direct labor costs of $4.50 per unit. Variable manufacturing overhead costs are applied to the product based on direct labor hours. The standard variable manufacturing overhead rate is $3 per direct labor hour. Each unit should require 0.25 direct labor hours for total variable manufacturing overhead costs per unit of $0.75.
Causes of direct labor efficiency variance
The standard cost usually includes variable costs such as direct material and direct labor. In order to make a proper estimate, management estimates the standard cost base on the unit of labor and material. For example, one unit of cloth requires 0.1Kg of raw material and 1 hour of labor. The completed top section of the template contains all the numbers needed to compute the variable manufacturing overhead efficiency (quantity) and rate (price) variances. The variable manufacturing overhead efficiency and rate variances are used to determine if the overall variance is an efficiency issue, rate issue, or both.
On the other hand, if workers take an amount of time that is more than the amount of time allowed by standards, the variance is known as unfavorable direct labor efficiency variance. Figure 8.4 shows the connection between the direct labor rate variance and direct labor time variance to total direct labor variance. Figure 10.43 shows accounting for day care business the connection between the direct labor rate variance and direct labor time variance to total direct labor variance. The direct labor efficiency variance is one of the main standard costing variances, and results from the difference between the standard quantity and the actual quantity of labor used by a business during production.
During the period, 600,000 feet of flat nylon cord costing $330,000 were purchased and used. When a company makes a product and compares the actual labor cost to the standard labor cost, the result is the total direct labor variance. When a company makes a product and compares the actual labor cost to the standard labor cost, the result is the total direct labor variance. The purpose of calculating the direct labor efficiency variance is to measure the performance of the production department in utilizing the abilities of the workers.
