How do you calculate labor cost per assembly?

Multiply direct labor hours by the loaded rate and the chargeable capture share, then add fixed setup labor. With 26 hr at $48/hr at 100 percent plus $220 setup, total loaded labor is $1,468.

What does the loaded labor rate include?

It bundles the technician wage plus payroll taxes, benefits, supervision, and a share of overhead such as cleanroom or fume-extraction cost. A bare wage of $24/hr often becomes a loaded $48/hr once burden is added.

What is a good labor cost per hour for optical assembly?

In this example the average lands at $56.46/hr because the $220 fixed setup is spread across 26 hours. The fewer hours a batch runs, the more that fixed setup inflates the per-hour figure.

Why is my per-hour cost higher than my labor rate?

Because fixed setup and documentation labor are amortized over the direct hours. At $48/hr loaded plus $220 over 26 hr, the effective per-hour cost rises to $56.46.

How does chargeable capture share affect the result?

It scales the variable labor you can actually bill. At 100 percent capture all 26 hours bill; drop to 90 percent and you recover only $1,123 of variable labor instead of $1,248.

Labor cost vs material cost on a fiber assembly?

On precision optical connectors labor typically dwarfs ferrule and epoxy material, often 60 to 80 percent of build cost, which is why touch-time reduction beats material sourcing for margin.

Labor Cost Per Assembly Calculator

Labor cost per assembly is the fully loaded human-labor portion of building a fiber optic or photonic interconnect, expressed as a batch total and an average per-hour figure. Process engineers and quoting estimators in optical connector and cable shops use it to price polishing, splicing, epoxy injection, and active-alignment work that stays stubbornly hands-on. Because optical assembly is labor-dominated rather than material-dominated, even a few minutes of extra touch time per termination move quote competitiveness. This calculator separates variable captured labor from fixed setup and traveler-documentation labor so you can see where margin actually leaks.

What this calculator does

Estimate optical assembly labor cost from labor hours, loaded labor rate, chargeable share, and fixed setup labor.
Use it when quoting patch cords, MPO trunks, fanouts, connectorized pigtails, photonic modules, or test-intensive optical assemblies.
It computes total loaded labor cost for an optical assembly batch and the resulting average cost per direct labor hour.

Formula used

Optical assembly labor cost = labor hours × loaded labor rate × chargeable share + fixed setup labor cost
Per-assembly labor cost = total labor cost ÷ labor hours

Inputs explained

Direct optical assembly labor hours:
Loaded optical assembly labor rate:
Chargeable labor capture share:
Fixed setup or documentation labor cost:

How to use the result

Use it when quoting connectorization or cable-assembly jobs, building a labor standard for a new optical product, or auditing where touch time exceeds plan.
It assumes your loaded rate already folds in benefits, overhead, and fixture depreciation; if those sit in a separate burden pool you will double count or undercount.

Current U.S. benchmarks

As of Jun 2026, average hourly earnings in U.S. manufacturing are $30.27 (BLS), up 4.4% from a year earlier. Burdened shop rates typically run 1.3 to 1.8 times earnings once benefits and overhead are loaded.
The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
