How do you calculate cable scrap cost?

Multiply scrapped length by cost per foot, apply the unrecoverable share as a capture factor, then add the disposal and handling charge. For 800 ft at $0.55, 90% unrecoverable and a $40 charge, total scrap cost is $436.

What does unrecoverable share mean here?

It is the fraction of scrap value you cannot get back through copper reclaim or reuse. At 90%, the variable scrap cost is $396 on 800 ft rather than the full $440, reflecting the small credit recovered.

What is cable scrap cost per foot?

Total scrap cost divided by scrapped length. In the example, $436 over 800 ft works out to $0.55 per scrapped foot — essentially the cost-per-foot once the near-full unrecoverable share and disposal charge are folded in.

What is a good cable scrap rate for a harness shop?

Many shops target under 3-5% of consumed cable as scrap. The dollar tool here does not compute rate, but pairing scrapped feet against total feet consumed tells you whether $436 of loss is normal or a red flag.

Why include a fixed disposal and handling charge?

Scrap is not free to get rid of — bins, hauling, and handling labor cost money regardless of length. The $40 fixed adder in the example keeps the estimate honest when scrap volume is small.

How can I reduce cable scrap cost?

Optimize cut plans to nest lengths, reduce setup offcuts, and track first/last-piece waste. Lowering the 800 ft scrapped directly cuts the $396 variable component; improving copper reclaim lowers the unrecoverable share.

Wire Harness, Cable & Electromechanical Assembly calculator

Cable Scrap Cost Calculator

Cable Scrap Cost puts a dollar figure on the wire and cable a harness shop throws away — the offcuts, mis-cut lengths, and setup waste that never make it into a shipped harness. It combines scrapped length, cost per foot, the share that is truly unrecoverable after copper reclaim, and a fixed disposal and handling charge. Continuous-improvement leads and cost estimators in cable and harness assembly use it to quantify scrap loss, justify cut-plan optimization, and load a realistic waste factor into quotes. Because copper prices swing and cut waste hides in plain sight, converting scrap feet into dollars is what makes the loss visible enough to act on.

What this calculator does

Estimate the cost of cable scrap on a cut-and-strip operation including lost material and disposal of unrecoverable offcuts.
Use it when high cut-off and setup waste is eroding margin and you need to quantify the dollar impact of cable scrap.
It computes the total dollar cost of scrapped cable — length times cost per foot adjusted for the unrecoverable share, plus a fixed disposal and handling charge — and the cost per scrapped foot.

Formula used

Total = scrapped cable length x cable cost per foot x unrecoverable share% + disposal and handling charge
Cost per foot = total cable scrap cost / scrapped cable length

Inputs explained

Scrapped Cable Length:
Cable Cost per Foot:
Unrecoverable Share:
Disposal and Handling Charge:

How to use the result

Use it to quantify scrap loss on a job, justify cut-plan or setup improvements, or set the waste allowance in a harness quote.
The unrecoverable share is a flat capture factor, not a copper-reclaim market model, so it will not track daily scrap-copper prices or credits you actually receive.

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).
