Wire, Cable & Conductor Manufacturing calculator

Cable Cut Length Yield Calculator

Plan equal cable blanks from continuous stock with full cut loss. Enter stock, finished blank, initial trim and cut loss at 0.001 mm resolution.

What this calculator does

  • Plan equal cable blanks from continuous stock with full cut loss.

Formula used

  • Usable stock = Starting stock − Reserved trim
  • Blanks = Floor(Usable stock ÷ (Blank length + Full cut loss))
  • Finished length = Blanks × Blank length
  • Remaining = Starting stock − Finished length − Trim − Blanks × Cut loss
  • Yield % = Finished length × 100 ÷ Starting stock

Inputs explained

  • Starting Continuous Stock: Measured length of the continuous stock piece.
  • Finished Blank Length: Required finished length of each equal blank.
  • Reserved Initial Trim: Total initial preparation allowance excluded from usable stock.
  • Full Cut Loss per Blank: Complete separating cut loss charged to every finished blank.

How to use the result

  • Best suited to cable blank cutting plans, stock length reconciliation.
  • Minimum clamp tails, partial final cuts and an already-qualified stock end are outside this model.

Current U.S. benchmarks

  • The producer price index for primary nonferrous metals (a broad metals benchmark, not copper alone) stands at 544.731 (BLS, Aug 2026), up 49.3% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,543 per tonne (IMF via FRED, Jul 2026).
  • The U.S. has 5,397 electrical equipment and appliances establishments employing about 369,437 workers (Census County Business Patterns, 2023).

Common questions

  • Is the final cut loss included? Yes. Every finished blank consumes its length plus one complete cut loss.
  • Can an exact stock end replace the last cut? No. This planning scope does not treat the original stock end as a qualified finished end.
  • Does remaining stock count as scrap? Not automatically. The remainder is reported separately from reserved trim and consumed cut loss.
  • Can I set cut loss to zero? Yes. Zero cut loss is supported when it represents your qualified cutting process.
