When this energy calculator is (and isn't) a good fit

Well suited for:

  • Comparing the running cost of different machines
  • Identifying which equipment drives most of your bill
  • Rough carbon footprint estimates for a specific line
  • Building inputs for ROI or equipment upgrade decisions

Not a replacement for:

  • Official utility bills or power-quality studies
  • Detailed demand / peak power charges
  • Complex time-of-use tariffs with many price bands
  • Regulatory carbon reporting without further validation

Electricity cost per job formula

Electricity cost per job = (total kW draw × active cutting minutes ÷ 60) × electricity rate ($/kWh), plus any auxiliary load you allocate to the same job window.

Use measured kW, utility tariff, and machine runtime to answer laser cutter power consumption questions, then carry the result into the hourly-rate model or full laser cutting quote.

Energy use

kWh per hour from rated load, load factor, and auxiliaries

Cost output

electricity cost per operating hour or reviewed job window

Auxiliary share

chiller, extraction, controls, compressor, and support load

Power consumption reference

Laser cutter energy cost calculator

Estimate laser cutter power consumption, auxiliary load, electricity cost, and carbon footprint before feeding electricity cost per job into a full laser cutting quote or shop hourly-rate model.

Energy cost worksheet

Use this electricity cost per job check to isolate utility assumptions before the full quote uses them for hourly rate, gas/energy, overhead, and margin decisions.

Energy worksheet: calculate electricity cost per job, send it to hourly-rate and laser quote calculators, then return to the quote packet.

Directional estimates only: Results are based on rated power, average load, and simplified tariff assumptions. Actual bills depend on real-time load variation, auxiliary systems, power factor penalties, demand charges, and detailed time-of-use structures. Calibrate the model against your own meter readings, utility bills, and tariff sheet before using it in customer-facing quote policy.

Equipment Parameters

Equipment Details

Machine power source

Use the laser source rating, chiller rating, extraction rating, and the machine documentation approved for your shop. Enter the measured or documented value you are willing to use in quote assumptions.

Average modeled operating load percentage

Operating Schedule

Energy Costs

Additional cost during peak hours

Time-of-use simplification

This model treats peak pricing as a simple percentage uplift on your base rate over a share of hours. It does not model detailed tariff ladders or demand charges. Use it to compare schedule assumptions, then validate the selected rate with your actual tariff sheet.

Auxiliary Systems

Average for your region; adjust using your utility or government data

Carbon input source

Replace the default carbon intensity with a value from your utility, regulator, or internal sustainability reporting source. Keep the source and review date with the quote packet when carbon cost is part of the decision.
