How to calculate power factor correction
This calculator finds power factor by dividing real power by apparent power — a measure of how efficiently electrical power is being used in an AC circuit.
How the calculation works
Power factor = (Real power ÷ Apparent power) × 100.
Example
80 kW real power against 100 kVA apparent power: (80÷100)×100 = 80%.

Pro Tips for Power Factor Correction
- A power factor of 100% (1.0) means all supplied power is doing useful work; lower values mean some power is 'wasted' as reactive power that doesn't do useful work but still requires generation and transmission capacity.
- Many commercial and industrial utility rate structures penalize low power factor, since it requires utilities to deliver more current for the same useful power.
Common Power Factor Correction Mistakes to Avoid
- Ignoring a low power factor because it doesn't show up directly on an energy (kWh) bill, when it can still trigger separate demand or power-factor penalty charges.
