To figure your KWH you need to add up your total wattage per hr. multipied by hrs per day. Take that number multipied by days per month. Divide that number by 1000 which gives you your KWH per month. Watts x Hrs per day x Days per month, divide by 1000. Take your KWH and multipied by KWH rate from electric bill.

Nice find Tom. They are usually $29 at Harbor Freight. I already have one or I might go in halves on a pair.
tolo13. the only problem with that method is that you have no idea how much wattage or amperage your devices are actually drawing without a meter of some sorts. The Kill-A-Watt meters are very low tech and easy to read. They willalso keep track of KWH if you want to see how much something uses over a week (like lights that are on a timer and not always running.
The wattage listed on a device is the MAXIMUM wattage that device should ever use. I stuck a Kill-A-Watt on a Sedra 9000 rated at 90W and it was drawing about 65W.
