How do you calculate plasma cutting cost per part?

Multiply parts by per-part consumables and power, add gas/torch setup and burdened labor for the total, then divide by parts. With 160 parts at $0.85 each plus $120 setup and $285 labor, total is $541 and cost per part is $3.38.

What is a good plasma cutting cost per part?

There is no universal target — it depends on part size, thickness, and amperage. The useful move is to compare your computed per-part figure (here $3.38) against your quoted price; you want the quote to clear cost plus your margin, not just machine rate.

Why are plasma consumables such a big share of cost?

Electrodes and nozzles wear with every pierce and arc-on second. At high amperage or with excessive pierces, a nozzle set can last only a few hundred inches, which is why the $136 consumables share in the example is separated out from setup and labor.

Plasma vs laser cutting cost — which is cheaper?

Plasma is usually cheaper to buy and run on thick carbon steel (over ~1/2 inch), while laser wins on thin sheet speed and edge quality. Run both cost calculators with the same part count and thickness to compare loaded cost per part directly.

Does this include the cost of the plasma table itself?

No — the machine hourly rate should be built into either your per-part figure or the burdened labor line. This calculator does not depreciate the capital equipment separately; fold that into your loaded rates.

How do I lower plasma cutting cost per part?

Reduce pierces by chaining cuts, run correct amperage for the thickness, replace consumables on a schedule rather than after failure, and spread the fixed $120 setup over more parts by batching jobs.

Welding & Fabrication calculator

Plasma Cutting Cost Calculator

Plasma cutting cost is the fully loaded price of running a plasma job — electrode and nozzle wear, shielding gas, compressed air, power draw, torch and gas setup, plus burdened operator time — divided down to a defensible cost per part. Fabrication estimators, job shop owners, and CNC plasma programmers use it to quote steel plate and structural jobs where consumable life swings margin more than most people expect. On a mechanized plasma table, a worn nozzle or dross-heavy cut can double your true cost per foot, so pricing off machine time alone leaves money on the floor. This calculator separates variable per-part cost from fixed setup and labor so you can see where the money actually goes.

What this calculator does

Estimate plasma cutting cost from pierce-and-cut count, per-part consumable cost, gas and electricity, and labor.
Use it when quoting CNC plasma cutting jobs and you need to load consumables (electrodes, nozzles), gas, electricity, and labor into the per-part cost.
It computes total plasma cutting cost as parts times per-part consumables and power plus gas/torch setup plus burdened labor, then divides by parts for cost per piece.

Formula used

Total plasma cutting cost = parts cut on the job × per-part plasma consumables and power + plasma gas and torch setup cost + operator labor with burden
Plasma cutting cost per part = total plasma cutting cost ÷ parts cut on the job

Inputs explained

Parts cut on the job:
Per-part plasma consumables and power:
Plasma gas and torch setup cost:
Operator labor with burden:

How to use the result

Use it when quoting a plasma-cut job, comparing plasma against laser or waterjet on thick steel, or checking whether a run is priced above your true loaded cost.
It assumes your per-part consumables figure already reflects real electrode and nozzle life at your amperage; if you plug in optimistic consumable wear, the per-part cost will read low.

Current U.S. benchmarks

The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial electricity averages 8.66 cents per kWh across the U.S. (EIA, Apr 2026), up 5.5% from a year earlier. Energy-intensive steps carry this directly into unit cost.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
The U.S. has 53,790 fabricated metal products establishments employing about 1,441,471 workers (Census County Business Patterns, 2023).
