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

Pro Tips for Power Factor Correction Ratio
- A ratio of 1.0 represents ideal power factor; most real-world industrial loads fall somewhere between 0.7 and 0.95 without correction.
- 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.
