The labor efficiency variance calculation presented previously shows that 18,900 in actual hours worked is lower than the 21,000 budgeted hours. Clearly, this is favorable since the actual hours worked was lower than the expected (budgeted) hours. The combination of the two variances can produce one overall total direct labor cost variance. Labor rate variance arises when labor is paid at a rate that differs from the standard wage rate. Labor efficiency variance arises when the actual hours worked vary from standard, resulting in a higher or lower standard time recorded for a given output.<\/p>\n<\/p>\n
Note that both approaches\u2014direct labor rate variance calculation and the alternative calculation\u2014yield the same result. Since rate variances generally arise as a result of how labor is used, production supervisors bear responsibility for seeing that labor price variances are kept under control. Labor yield variance arises when there is a variation in actual output from standard. Since this measures the performance of workers, it may be caused by worker deficiencies or by poor production methods. Labor mix variance is the difference between the actual mix of labor and standard mix, caused by hiring or training costs. We have demonstrated how important it is for managers to be aware not only of the cost of labor, but also of the differences between budgeted labor costs and actual labor costs.<\/p>\n<\/p>\n
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. As a result of this unfavorable outcome information, the company may consider retraining its workers, changing the production process to be more efficient, or increasing prices to cover labor costs. In this case, the actual rate per hour is $9.50, the standard rate per hour is $8.00, and the actual hours worked per box are 0.10 hours. This is an unfavorable outcome because the actual rate per hour was more than the standard rate per hour. As a result of this unfavorable outcome information, the company may consider using cheaper labor, changing the production process to be more efficient, or increasing prices to cover labor costs.<\/p>\n<\/p>\n

Direct labor rate variance is equal to the difference between actual hourly rate and standard hourly rate multiplied by the actual hours worked during the period. The variance would be favorable if the actual direct labor cost is less than the standard direct labor cost allowed for actual hours worked by direct labor workers during the period concerned. Conversely, it would be unfavorable if the actual direct labor cost is more than the standard direct labor cost allowed for actual hours worked. To compute the direct labor quantity variance, subtract the standard cost of direct labor ($48,000) from the actual hours of direct labor at standard rate ($43,200). This math results in a favorable variance of $4,800, indicating that the company saves $4,800 in expenses because its employees work 400 fewer hours than expected. The difference between the standard cost of direct labor and the actual hours of direct labor at standard rate equals the direct labor quantity variance.<\/p>\n<\/p>\n
