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

Energy Cost Calculator

Estimate power consumption, energy costs, and carbon footprint.

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. Before you calibrate the model with your own data, it is common to see differences in roughly the 15–20% range. Always compare against your own meter readings and utility bills.

Equipment Details

Typical power ranges (for reference only)

Modern fiber lasers are commonly around 2–3 kW for light work and 4–12 kW for heavy plate; older CO2 models are often in the 2–6 kW range. Always check your own machine's nameplate or manual and enter that value here.

Typical operating load percentage

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 explore rough savings from shifting work out of peak hours, then validate with your actual tariff sheet.

Auxiliary Systems

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

Typical regional values (order-of-magnitude)

  • Coal-heavy grids: ~800–950 g CO2/kWh
  • Mixed generation (gas + renewables): ~350–550 g CO2/kWh
  • Hydro / nuclear heavy grids: ~20–100 g CO2/kWh

For serious carbon accounting, replace the default with numbers from your local utility or national inventory.
