How do I estimate the fully loaded cost of a wire harness?

Use the Wire Harness Cost calculator. It multiplies standard bench build time by your loaded labor rate, scales it by a labor-efficiency factor for realistic productive time, then adds flat wire, connector, loom, and overhead content per unit. You get a total per harness plus an effective cost-per-minute you can benchmark against your standard times. Pair it with Terminal Cost and Connector Cost for termination-heavy bills.

How many pull tests should I run per lot?

The Pull Test Sample Size calculator sizes destructive crimp pull-testing against your good-piece capacity. It combines output per cycle, available cycles, uptime, and first-pass yield to show how many samples a shift can actually cover. That keeps sampling defensible under IPC/WHMA-A-620 practice without pulling so many terminations that you erode margin. Use it alongside Continuity Test Workload to load the full test bench.

What is driving my terminal and connector cost on a dense harness?

Run Terminal Cost and Connector Cost separately. Terminal Cost multiplies termination count by cost per crimp, applies a crimp first-pass yield for pull-test rejects, and adds the applicator setup charge per gauge change. Connector Cost captures housing piece price, contact loading labor, insertion yield, and per-lot fixture setup. Comparing per-crimp and per-connector rates tells you whether to consolidate splices or change connector strategy.

How do I size continuity and functional test time for a harness job?

Harness Test Time and Continuity Test Workload convert a test queue into schedulable hours. Enter the workload, a measured completion rate from your test log, and a setup and handling allowance for fixturing, staging, and retest. The result is a base run time and an allowance-adjusted required time you can drop straight into the schedule. Adjust the allowance to model minor stops without redoing the math.

When does automating a cut-crimp or test fixture pay off?

Use Test Fixture Payback to compare the fixture or applicator investment against the labor and scrap it removes. Feed it your current Crimp Labor Load or Harness Test Time hours and the recurring cost the fixture eliminates. Short runs rarely justify dedicated tooling because the setup adder dominates, while high-volume termination-heavy builds amortize it quickly. Check Cable Scrap Cost first to capture waste the fixture may also cut.

How much is harness rework really costing me?

Harness Rework Cost multiplies lot size by a per-unit repair labor rate, scales it by the defect occurrence percentage so you only pay for units that fail, then adds scrapped connectors and terminals. Modeling a 5 percent versus 20 percent failure rate shows total exposure and cost per reworked harness. That number is what justifies a crimp process fix or added continuity coverage over living with the rework loop.
