Enter the average load and the maximum load of a system into the calculator to determine the load factor.

The following formula is used to calculate an electrical load factor.

LF = AL / ML *100
• Where LF is the load factor (%)
• AL is the average load (KWH)
• ML is the maximum or peak load (KWH)

To calculate a load factor, divide the average load by the maximum or peak load, then multiply by 100.

A load factor is defined as the percentage or ratio of the average load of an electrical system and the maximum or peak load of that same system over a given time period. The higher the load factor, the less likely a system is able to handle a sudden spike in power consumption.
