Efficiency 101: How to Calculate Efficiency in Any Situation
You must use the efficiency formula, output divided by input, to calculate efficiency. It will give you a ratio to convert to a percentage by multiplying by 100. For example, if a machine produces 100 units per hour and requires 200 watts of power, the efficiency can be calculated as 100/200 = 0.5 or 50%.

Introducing Ceiling Fan Energy Index (CFEI)
The least efficient fan (highest power for a given airflow) is Fan 5, which has a CFEI rating of 0.63. While both Fan 1 and Fan 5 would comply with the cfm/W minimum-efficiency requirement, Fan 1 would significantly exceed the DOE minimum-efficiency requirement of 1.00 at high speed, while Fan 5 would be non-compliant, as its CFEI is less than ...

ε is the efficiency of the fan (which is normally between 50% and 90% dependent upon gas and design). You may enter this value as a factor (e.g. 0.67) or a percentage value (e.g. 67). The fan calculator will recognise the correct value; i.e. you cannot have a factor>1.0 and Fans will assume that your fan will have an efficiency greater than 1%.
