Annual Energy Savings   |   Motor Efficiency Guide
To calculate a motor's annual energy cost:
1.  Enter the Horsepower rating of the motor.
2.  Enter your Average Energy Cost.   For a typical electric bill, divide the total dollars by the total kilowatt-hours to get this figure.
3.  Enter the Motor Efficiency.   Use the motor's nameplate efficiency, or use the
Motor Efficiency Guide
to help determine this value.
4.  Click Calculate.
5.  Read the Annual Energy Cost for 3000, or 8000 hours annual usage.   3,000 hours usage is typical of HVAC fans and pumps that run 12 hours, 5 days a week, or 1-1/2 shift industrial plants.  8,000 hours is typical for motors running 24/7 with a few weeks shutdown.
Note: Calculations assume a 75% motor loading factor.  Studies show that most motors are about 75% loaded, with a few exceptions, such as compressors.
