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.

Pro Tips for Motor Annual Energy Cost
- Use actual motor power draw (which reflects load and efficiency) rather than nameplate horsepower rating alone for an accurate energy estimate.
- 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.
