Where do earned standard hours come from?

Each completed work order credits standard hours for the operations it finished. Add those credits for the period, and take clocked hours from the same orders so the two cover one scope.

Can efficiency go above 100%?

Yes, when crews beat the standard. Treat it as a signal before a reward: the standard may be loose, or quality and rework may sit outside the measure. Verify with actual good units.

Why is the hours variance signed this way?

Earned hours minus clocked hours is positive when the crew produced more standard work than the clock shows, the favorable direction. A negative number is adverse and will drive the efficiency rate below target.

Is paid time the same as clocked hours?

No. Clocked hours should cover time applied to these orders, not vacation, training or indirect work. If you enter paid time, every hour of absence reads as inefficiency and the rate collapses.

Lean Manufacturing & Operations calculator

Direct Labor Efficiency Calculator

Compare standard hours earned with hours clocked to see how efficiently paid labor converts into completed work. You need earned hours, clocked hours and the efficiency target from your operating plan.

What this calculator does

Direct labor efficiency against your target, with the hours variance and the standard hours a target needs.

Formula used

Direct labor efficiency = earned standard hours ÷ actual clocked hours × 100
Gap to target = target efficiency − direct labor efficiency
Hours variance = earned standard hours − actual clocked hours; favorable is positive
Earned hours at target = actual clocked hours × target efficiency ÷ 100
Earned hours below target = MAX(0, earned hours at target − earned standard hours)

Inputs explained

Earned Standard Hours: Standard hours credited to completed work orders this period.
Actual Clocked Hours: Clocked hours from the time system for those same orders.
Target Labor Efficiency: Labor efficiency goal from the plant operating plan.

How to use the result

Best suited to weekly direct labor review, checking standards after a method change, sizing recovery after a slow month.
A loose standard flatters efficiency; an unreachable one hides real improvement. Blended crews and product mix changes move the rate, so compare like periods.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
