Your power factor changes depending on what is turned on. You can buy a power factor/watt meter or you can build something to measure it.
I use a closed loop hall effect current sensor with about 300 kHz frequency response which also allows meet to capture startup up current waveforms from by central air conditioner compressor. You have to capture the vector current and voltage to muliply the two together to get true power and apparent power numbers.
A residential service pays for true power not apparent power so correcting PF does little for your electric bill. You only save on small additional wiring losses due to higher current as result of poor power factor.
