How do you calculate kitting workload time?

Divide the number of kits by the pick rate to get base time, then multiply by one plus the allowance. For 120 kits at 12 units/min with a 10% allowance, base time is 10 hours and required time is 11 hours.

What does the allowance percentage cover?

It covers setup, part handling, bin travel, verification scans, and routine micro-delays that a pure pick-rate calculation ignores. A 10% allowance turns a 10-hour base into 11 required hours.

Why is required time higher than base time?

Base time assumes uninterrupted picking at rated speed, which never happens. The allowance factor scales it up so your schedule reflects real cell conditions rather than an idealized rate.

What is a good allowance for kitting?

Well-run kitting cells with clear travel paths run 8-12%; congested stockrooms or heavy verification can push 15-20%. The 10% default is a reasonable planning figure for an organized cell.

How do I convert pick rate into the same units?

Pick rate is in units per minute, so the calculator handles the minutes-to-hours conversion internally. At 12 units/min, 120 kits take 10 minutes of pure picking only if each kit is one unit; here the result is expressed as staged hours after conversion.

How do I use this to staff a shift?

Divide required hours by the shift length. Eleven required hours across a single 8-hour shift means you need at least two kitters, or you start staging the prior shift.

Kitting Workload Calculator

Kitting workload is the labor time needed to pull, sequence, and stage component kits so an assembly line never starves. Materials and line-feed supervisors in harness and box-build shops use it to size the pre-shift kitting crew and to promise a ready-by time to production. Unlike a raw pick count, it adds a realistic allowance for setup, part handling, and the small delays that always creep into a kitting cell. Getting it right is the difference between a line that starts on time and one waiting on missing bags.

What this calculator does

Estimate kitting workload 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 kitting workload in wire harness, cable and electromechanical assembly is changing rate or allowance and you want to see the impact.
It converts a kit quantity and a pick rate into base kitting hours, then inflates that by an allowance factor to give the realistic required time.

Formula used

Base kitting workload time = kitting workload workload ÷ kitting workload completion rate
Required kitting workload time = base kitting workload time × allowance factor

How to use the result

Use it when planning a kitting shift, staffing a line-feed cell, or checking whether kits can be staged before an assembly run starts.
A single average pick rate assumes uniform kit complexity; a run mixing simple and part-dense kits will deviate from the estimate.

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).
