The Power Factor Calc

Power Factor Calculator

Quick & Easy Power Factor Calculations

Power Factor Calculator makes electrical efficiency calculations fast, simple, and accurate. Whether you're an electrician, engineer, technician, or student, this app helps you instantly compute Power Factor (PF), Active Power (P), or Apparent Power (S) using the core power factor relationships:
PF = P ÷ S
P = PF × S
S = P ÷ PF

Just enter any two values — the app calculates the third instantly.
