How do you calculate cable shielding cost?

Multiply cable length by the shield material rate and coverage percentage, then add the termination and grounding cost. Here: 800 ft × $1.35 × 88% + $240 = $1,190.40.

What is the per-foot shielding cost in this example?

Total cost of $1,190.40 divided by 800 ft gives $1.488 per foot, which folds in both material and the fixed termination charge.

Does higher shield coverage cost more?

Yes — coverage acts as a multiplier on material cost, so moving from 88% to 95% braid raises the variable portion proportionally. The termination cost stays flat.

Braid vs foil shielding — which is cheaper?

Foil is usually lower material cost per foot but needs a drain wire and gives less flex-life; braid costs more but offers higher coverage and durability. Enter each option's $/ft to compare directly.

Why separate variable and fixed cost?

Material ($950.40 here) scales with length while termination ($240) does not, so on short runs the fixed portion dominates the per-foot price and long runs dilute it.

Should grounding hardware go in the termination field?

Yes — backshells, ground rings, and the labor to terminate and bond the shield all belong in the fixed termination and grounding cost so the per-foot number is complete.

Cable Shielding Cost Calculator

Cable shielding cost is the total spend to add EMI/RFI protection to a cable run — the braid or foil material scaled by how much of the circumference it covers, plus the labor to terminate and ground each shield. Cable engineers and estimators use it when quoting shielded assemblies or deciding between 85% and 95% braid coverage on a design. Because termination and grounding are fixed per assembly while material scales with length, the per-foot cost tells you where a longer run becomes cheaper to shield. It turns a shielding spec into a defensible line-item price.

What this calculator does

Estimate cable shielding cost from shield material per foot, achieved braid coverage and the one-time termination and grounding setup.
A cable designer specifying braid plus foil for EMI control uses it to price shielding material against coverage targets and grounding hardware.
It totals shield material cost scaled by coverage, adds fixed termination and grounding labor, and divides by length for a per-foot cost.

Formula used

Total = cable length x shield material rate x shield coverage% + termination cost
Per foot = Total / cable length

Inputs explained

Cable run length to be shielded:
Braid or foil shield material cost:
Shield coverage of the cable OD:
Termination and grounding labor cost:

How to use the result

Use it while quoting a shielded cable assembly or comparing coverage options and their cost impact.
It models coverage as a linear multiplier on material, which is a fair estimate for braid but does not capture drain-wire, tape overlap, or double-shield construction exactly.

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).
