How to calculate motor load percentage
This calculator finds motor load percentage by dividing measured power by rated power — checking how heavily loaded a motor is relative to its capacity.
How the calculation works
Load percentage = (Measured power ÷ Rated power) × 100.
Example
6 kW measured power on an 8 kW rated motor: Load percentage = (6 ÷ 8) × 100 = 75%.

Pro Tips for Motor Load Percentage
- Motors running consistently well below 50% load often operate less efficiently than when running closer to their rated capacity — this can indicate an oversized motor for the application.
- Motors running above 100% of rated load risk overheating and premature failure — investigate promptly if load percentage exceeds rating.
Common Motor Load Percentage Mistakes to Avoid
- Ignoring a load percentage significantly below 50%, which can indicate an oversized, inefficiently-operating motor worth right-sizing.
