How to calculate power factor correction ratio

This calculator finds power factor ratio by dividing real power by apparent power — expressed as a decimal ratio rather than a percentage.

How the calculation works

Power factor ratio = Real power ÷ Apparent power.

Example

75 kW real power against 90 kVA apparent power: 75÷90 ≈ 0.833.

Frequently asked questions

How is Result calculated?

Result = [Real power] ÷ [Apparent power].

Pro Tips for Power Factor Correction Ratio

  1. A ratio of 1.0 represents ideal power factor; most real-world industrial loads fall somewhere between 0.7 and 0.95 without correction.
  2. Power factor correction equipment (like capacitor banks) can improve a low ratio, reducing utility penalty charges in many commercial rate structures.

Common Power Factor Correction Ratio Mistakes to Avoid

  • Treating a power factor ratio below 1.0 as necessarily indicating a problem, when it's a very normal characteristic of many inductive loads like motors, just one that some utilities specifically charge extra for below a certain threshold.
