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

## Load Factor Formula

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)

## Load Factor Definition

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.

## Load Factor Example

How to calculate a load factor?

**First, determine the average load.**Calculate the average load for the time period.

**Next, determine the maximum load.**Calculate the peak load during the same time period.

**Finally, calculate the load factor.**Calculate the load factor using the formula above.

## FAQ
