Compare productive labor hours with standard hours allowed for actual output, valued at your standard hourly rate. All monetary amounts are USD; no FX conversion.
Labor efficiency variance (USD)
Choose inputs and submit, or load the synthetic example. Edited inputs require a fresh result.
(Actual productive hours − standard hours allowed for actual output) × standard hourly rate
ONE CLEAR OPERATING QUESTION
At rate 20, actual 60 hours minus allowed 50 hours gives 200 unfavorable; reversing the hour difference reverses its sign.
10 extra hours × USD 20/hour = USD 200 unfavorable
10 fewer hours than allowed × USD 20/hour = USD 200 favorable
At rate 20, actual 60 hours minus allowed 50 hours gives 200 unfavorable; reversing the hour difference reverses its sign.
THE FIELD NOTES
Use the result now, then read the practical notes for assumptions, examples, limitations, and the choices behind it.
50 allowed hours; 10 extra hours × standard rate USD 20.00/hour = USD 200.00 unfavorable. This is not actual payroll savings. No FX conversion.
Multiply actual output by standard hours per unit. Subtract those allowed hours from actual productive hours, then multiply by the standard hourly rate. Positive means unfavorable and negative means favorable under this stated convention.
100 actual units at 0.5 standard hours allow 50 hours. Actual 60 hours adds 10 hours at standard rate 20.00, or 200.00 unfavorable. The same difference is 1,200.00 minus 1,000.00 at the standard rate.
Use the labor cost per unit calculator to examine labor spend per unit separately; an efficiency variance values hours at the standard rate rather than the actual wage bill. Use the manufacturing lead time calculator to examine elapsed production stages separately from labor-hours variance.
Use decimal productive hours from one matched job or cohort. Paid idle time, wage-rate changes and revised standards require other analysis. A variance is not evidence of employee conduct, quality or actual payroll savings; zero rate does not erase a time difference. All monetary inputs and results are USD only; no exchange-rate conversion is performed.

Multiply actual output by standard hours per unit. Subtract those allowed hours from actual productive hours, then multiply by the standard hourly rate. Positive means unfavorable and negative means favorable under this stated convention.
100 actual units at 0.5 standard hours allow 50 hours. Actual 60 hours adds 10 hours at standard rate 20.00, or 200.00 unfavorable. The same difference is 1,200.00 minus 1,000.00 at the standard rate.

Use the standard hours allowed for the actual output produced: actual units multiplied by standard hours per unit, not the budgeted production volume.
Under this tool's actual-minus-standard convention, a positive monetary variance is unfavorable and a negative one is favorable; neither identifies its cause.
No. It values an hours difference at your entered standard rate. Actual wage-rate variance, paid idle time and payroll calculations are outside this worksheet.
