How to calculate motor annual energy cost

This calculator finds annual motor energy cost by multiplying motor power (in kW) by annual operating hours — giving total annual energy use, which can then be multiplied by an electricity rate for cost.

How the calculation works

Annual energy use = Motor kilowatts × Annual operating hours (result in kWh; multiply by electricity rate for a dollar cost).

Example

A 5 kW motor running 2,000 hours/year: Annual energy use = 5 × 2,000 = 10,000 kWh/year.

Frequently asked questions

How is Result calculated?

Result = [Motor kilowatts] × [Annual operating hours].

Pro Tips for Motor Annual Energy Cost

  1. Use actual motor power draw (which reflects load and efficiency) rather than nameplate horsepower rating alone for an accurate energy estimate.
  2. Multiply the resulting kWh figure by your electricity rate to get an actual annual dollar cost, useful for evaluating motor efficiency upgrades.

Common Motor Annual Energy Cost Mistakes to Avoid

  • Using nameplate rated power as if the motor always runs at 100% of that rating, when actual load and resulting power draw often varies from the nameplate maximum.

When to Use This Calculator

This calculator finds annual motor energy cost by multiplying motor power (in kW) by annual operating hours — giving total annual energy use, which can then be multiplied by an electricity rate for cost.
