Calculate power factor from real power (kW) and apparent power (kVA).
Power factor is the ratio of real power (which does useful work) to apparent power (what the supply actually delivers). This calculator finds power factor directly from measured or nameplate kW and kVA values — useful for checking whether power factor correction is needed to avoid utility penalties.
Given: A panel meter shows 85 kW real power and 100 kVA apparent power.
Result: PF = 85 ÷ 100 = 0.85.
Most utilities consider 0.9 or above good; many apply penalty charges below 0.85–0.9, and India's electricity boards commonly require above 0.9 to avoid penalties.
Installing capacitor banks near inductive loads (motors, compressors) is the standard industrial method for power factor correction.
No — 1.0 (unity) is the maximum theoretical value, representing all apparent power being used as real power.
