Generator Load Calculator
Calculate a generator's actual load from its rated size and load percentage (Load = Size × (Load % ÷ 100)).
Formula
Load = Size × (Load % ÷ 100)
- Load
- Actual load, in kilowatts
- Size
- Generator's rated size, in kilowatts
- Load %
- Percentage of rated capacity in use
What this calculator does
Calculates the actual load a generator is carrying from its rated size and load percentage.
Use cases
- Check whether a generator is running within its optimal load range
- Estimate actual load from a percentage reading on a generator display
- Compare loading across generators of different rated sizes
