Enter your bill readings

Use the kWh and kVAh readings printed on your bill. The rate is your all-in cost per unit (energy charge plus other per-unit charges). The load is only used to estimate the capacitor size.

Enter kWh and kVAh to see your result.

How the calculator works

Power factor = kWh ÷ kVAh
Extra units = kVAh − kWh
Units at power factor 0.98 = kWh ÷ 0.98
Capacitor (kVAr) = kW × (tan φ1 − tan φ2)

The first line gives your power factor. The second shows how many units you pay for beyond the real energy you used. The third shows what you would be billed after correcting to 0.98, which is a practical target. In the last line, φ1 is the angle for your present power factor and φ2 for the target.

What is a good power factor?

  • 0.95 and above: good. Little to gain from correction.
  • 0.90 to 0.95: acceptable, but you may still be paying some extra units.
  • Below 0.90: low. Correction usually pays for itself.

Where to find kWh and kVAh on your bill

Look in the consumption or meter reading section of your bill. Many bills list both kWh (real energy) and kVAh (apparent energy), and show the billing units. If your bill shows only one of them, send it to us and we will read it for you.

This is an estimate. Actual billing depends on your consumer category, your tariff and the current tariff order. Peak and off-peak rates, fixed charges and other items are not included. For an exact figure, send us your bill.
