How do you calculate crimp labor hours?

Divide the crimp count by the crimp rate per minute for base minutes, convert to hours, then apply the allowance. 120 crimps at 12/min is 10 hours base, and a 10% allowance gives 11 hours.

What is a realistic crimp rate?

A semi-automatic bench press with a fed operator can sustain 10-20 crimps per minute on a consistent gauge. Frequent applicator swaps drop that sharply, which is why the allowance exists.

Why separate crimp labor from assembly labor?

Crimping is often a distinct station with its own applicators and rate. Costing it separately lets you load the crimp cell independently and spot it as a bottleneck.

What allowance should crimping use?

For a single-applicator run 10% is reasonable. High-mix termination with constant die changes can justify 25% or more; measure your changeover-to-run ratio.

Does this include pull-test time?

Only if sample pull-testing is folded into the crimp rate. If it is a separate quality step, calculate and add those hours.

Base time vs. required time — what changes?

Base time is the pure crimping hours from count divided by rate. Required time adds the allowance for setup and delays, and it is the figure you staff and schedule to.

Wire Harness, Cable & Electromechanical Assembly calculator

Crimp Labor Load Calculator

Crimp labor load is the operator time needed to terminate a given number of crimps, including applicator setup, wire insertion, cycling the press, and pull-testing samples. Cell leads and estimators use it to balance termination stations, staff a shift, and cost the crimping portion of a harness separately from routing and dressing. Crimp rate is highly sensitive to applicator changeover and wire gauge, so a realistic allowance matters. This calculator converts a crimp count and per-minute rate into hours and inflates it for setup and delays.

What this calculator does

Estimate crimp labor load for wire harness, cable and electromechanical assembly using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Use it when crimp labor load in wire harness, cable and electromechanical assembly is changing rate or allowance and you want to see the impact.
It computes required crimp labor hours from the crimp count divided by the per-minute crimp rate, scaled by a setup and delay allowance.

Formula used

Base crimp labor load time = crimp labor load workload ÷ crimp labor load completion rate
Required crimp labor load time = base crimp labor load time × allowance factor

Inputs explained

Crimps to complete:
Crimp rate per operator:
Setup, handling, and delay allowance:

How to use the result

Use it when loading a crimp station, staffing terminations, or costing the crimp operation apart from the rest of the build.
One average rate blends fast repeat crimps with slow applicator changeovers; split by applicator or gauge when the mix is wide.

Current U.S. benchmarks

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).
Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
The U.S. has 5,397 electrical equipment and appliances establishments employing about 369,437 workers (Census County Business Patterns, 2023).
