How accurate is the energy cost calculator?

This calculator uses your equipment power, operating schedule, and rate assumptions to estimate energy use and cost. Actual utility bills depend on factors like efficiency, power factor, varying loads, and tariff structure, so treat the results as directional estimates and compare them with your own meter and billing data.

What is included in total power consumption?

Total power includes equipment rated power plus auxiliary systems (cooling, extraction, controls). Total power equals rated load multiplied by the average load factor plus any auxiliary power you enter for cooling/extraction systems.

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

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 support layer

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

Support handoff: owns electricity cost per job, feeds the hourly-rate and laser quote calculators, and returns to the quote packet.

Add to hourly rate Power consumption reference Use in laser cutting quote

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.

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

Cooling System Power (kW)

Extraction/Ventilation Power (kW)

Grid Carbon Intensity (g CO2/kWh)

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.
