Where should the routing rate come from?

From a timed run of the actual car. Use several runs and take the average, or a documented standard if the cell has one. A rate from a different harness family will misstate this one by a wide margin.

How is the allowance factor applied?

It is added to base hours, not multiplied into the rate. A 20% allowance on 20 base hours adds 4 hours, so the required time is 24 hours. Enter setup, handling and delay as one share.

Why publish minutes per point?

Because a station talks in minutes. Points per hour hides the change when the point count moves; minutes per point shows the pace each position must hold to finish inside the required hours.

Does a faster routing rate always help?

Only when quality and handling keep up. Cutting setup and handling time or completing points before the car reaches the station lowers required hours without pushing operators past a sustainable pace.

Harness Routing Labor Calculator

Harness routing time comes from the points to be routed and the rate one operator achieves. This page adds the setup and handling allowance, then shows the minutes each point really costs.

What this calculator does

Routing hours for a car's harness points, with setup and handling allowance, against a target the user enters.

Formula used

Base hours = routing points ÷ points routed per hour
Allowance hours = base hours × allowance ÷ 100
Required hours = base hours + allowance hours
Minutes per point = required hours × 60 ÷ routing points
Gap = required hours − target hours

Inputs explained

Harness Routing Points per Car: Routing points awaiting installation on one car.
Routing Rate per Operator: Points one operator completes in an hour.
Setup and Handling Allowance: Share added for setup, handling and delays.
Target Routing Hours per Car: Routing hours the car is allowed to take.

How to use the result

Best suited to quoting a wiring station, checking a shift against the routing, setting the standard time for a harness build.
A single rate cannot capture very different routing sections; split those into separate estimates. The target is the user's own standard, not an industry benchmark.

Current U.S. benchmarks

Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
