Labour Efficiency Variance Meaning

Accounting glossary · Understand, connect, apply

The labour efficiency variance measures the cost effect of using more or fewer labour hours than the standard hours allowed for actual output, valued at the standard hourly rate.

Example

Output is allowed 240 standard hours, while actual working time is 250 hours. At a standard rate of 18, the efficiency variance is 10 × 18 = 180 unfavourable.

Formula and assumptions

Efficiency variance = (actual hours − standard hours allowed) × standard rate; positive means unfavourable

Remember the difference

Compare hours for the same output and specify idle-time treatment. Equipment failures, material quality and unrealistic standards can affect the variance; it is not automatically evidence of slow workers.
