Labor Rate Variance Calculator
Enter the hours worked, the rate you actually paid, and the rate you budgeted: this calculator returns the labor rate variance in dollars and tells you whether it is favorable or unfavorable. It also includes two extra modes no competing tool offers, labor efficiency variance and total labor cost variance, so you can see the full picture in one place.

The labor rate variance formula
Labor Rate Variance = Actual Hours Worked × (Standard Rate − Actual Rate)
Actual hours worked is the total labor time logged in the period. The standard rate is the budgeted or expected wage per hour, and the actual rate is the wage really paid, including any overtime premium folded into the average. A positive result is favorable: you paid less than budgeted. A negative result is unfavorable: you paid more than planned. A zero result means actual and standard rates matched exactly.
How to use the calculator
Pick the mode that matches your question. Rate variance answers "did we pay the right wage" from actual hours, actual rate, and standard rate. Efficiency variance answers "did we use the right number of hours" from standard hours allowed, actual hours, and the standard rate. Total cost variance combines both and shows each component separately, so a favorable rate variance hiding an unfavorable efficiency problem cannot slip past you.

Worked example, checked against the tool
A workshop logs 120 actual hours. Workers were paid $18 per hour against a budgeted standard rate of $20 per hour.
Labor rate variance = 120 × ($20 − $18) = 120 × $2 = $240.00 Favorable. Actual labor cost was $2,160 against a standard cost of $2,400, so the variance is 10.00% of the standard cost. The calculator returns exactly these figures.
In efficiency mode, if the standard hours allowed for the output were 100 but 120 were worked at the $20 standard rate: (100 − 120) × $20 = −$400.00 Unfavorable. In total mode with an $18 actual rate, the +$240 rate component and −$400 efficiency component combine to −$160.00 Unfavorable overall.
What competing calculators miss
The best-known labor rate variance tools stop at the single dollar figure: three inputs in, one number out. None of them show the actual and standard cost totals, the per-hour rate difference, or the variance as a percentage of standard cost, which is the figure managers actually use to decide whether a variance is material. None offer an efficiency variance mode, even though rate and efficiency are the two halves of every labor cost analysis, and none split total variance into its rate and efficiency components. This page does all three, verifies every worked example against the live tool, and lets you copy or share the full breakdown.
Frequently asked questions
What is labor rate variance?
It is the difference between what labor actually cost and what it should have cost at the budgeted wage rate, for the hours actually worked. It isolates the wage-rate effect from the hours-used effect.
What does a favorable labor rate variance mean?
You paid less per hour than budgeted, so the variance is positive. Common causes: hiring at lower wage grades, less overtime than planned, or a favorable shift in the mix of skilled and unskilled labor.
What does an unfavorable variance mean?
You paid more per hour than budgeted. Typical causes: overtime premiums, temporary or contract staff at higher rates, wage increases the standard was not updated for, or a shift toward higher-paid skill grades.
Can labor rate variance be zero?
Yes. When the actual average rate equals the standard rate exactly, the variance is zero regardless of how many hours were worked. Hours effects belong to efficiency variance, not rate variance.
What is the difference between rate variance and efficiency variance?
Rate variance measures the wage difference at actual hours: AH × (SR − AR). Efficiency variance measures the hours difference at the standard rate: (SH − AH) × SR. Together they explain the total labor cost variance.
Should overtime be included in the actual rate?
Yes, use the blended average rate actually paid, including overtime premiums. Otherwise the overtime cost hides inside efficiency variance, where it does not belong.
Does inflation affect labor rate variance?
Yes. If market wages rise and the standard rate is not updated, the variance turns unfavorable through no fault of operations. Review and reset standards regularly so the metric keeps measuring what it should.
Do union contracts affect the variance?
They can. Union-negotiated wage changes alter the actual rate directly, and grade or seniority rules change the labor mix. Standards should reflect the contract in force.
Should bonuses be included in the actual rate?
If bonuses are a normal part of hourly compensation, fold them into the blended actual rate. One-off or discretionary awards are usually analyzed separately.
How often should labor rate variance be calculated?
Monthly or at project close is typical. High-volume operations with volatile staffing sometimes track it weekly so unfavorable trends get caught early.
