Formula

Cost/Unit = (Power kW × Time Hours × Rate) / Units Produced

Finds the total electricity cost for a production run and divides it by the number of finished units produced.

Worked Example

A 50 kW machine running for 3 hours at $0.20/kWh producing 1,000 units results in an energy cost of $0.03 per unit.

Power and Production Costs

In high-energy sectors, electricity can be a larger cost than direct labor.
  • Monitor your power factor to avoid utility surcharges.
  • Production slowdowns dramatically increase the per-unit energy cost.
  • Off-peak manufacturing can save up to 40% on utility bills in some regions.

Understanding energy per unit is key to profitable volume manufacturing.

You can also calculate changes using our Appliance Running Cost Calculator or Diesel Consumption Calculator.

Frequently Asked Questions

What is kW load on a machine?

The "kilowatt draw" is the amount of power the machine uses while actively running. Check the nameplate or use an industrial power meter.

How can I lower energy costs in manufacturing?

Run high-draw machines during off-peak electricity hours and invest in energy-efficient servo motors.

Should I include idle time?

Yes, if the machine draws significant power while waiting for materials, that time should be added to the production run duration.
