Power Factor Calculator
Calculate power factor, apparent power (kVA), real power (kW), and reactive power (kVAR) for single-phase or three-phase electrical systems. Optimize energy efficiency and reduce electricity costs.
Step 1: Electrical Parameters
Understanding Power Factor
Power factor is the ratio of real power (kW) to apparent power (kVA). A high power factor (close to 1) indicates efficient energy use, while a low power factor means wasted energy and higher electricity costs.
Step 2: Calculation & Results
About Power Factor Correction
Low power factor can increase electricity bills due to utility penalties. Power factor correction capacitors can improve PF, reduce reactive power, and save energy costs.

Power Factor Calculation Formulas
PF = P / S = cos(θ)
Where: P = Real Power (kW), S = Apparent Power (kVA), θ = Phase Angle. For three-phase: S = √3 × V × I, P = √3 × V × I × PF.
