You can purchase a device that records the watt usage of a particular electric device. Thinkgeek.com has such a device, as do other sites.

Said device plugs into the wall outlet (or some form of power supply) and the device you wish to record watt usage on plugs into this device.

The device has a small LED screen that shows data (such as how many watts being used). You will need to look at the electric bill of your home and they will show the rate in which they charge for each kilowatt (ie. 1000 watts) used per hour. You can calculate how many kilowatts your electronic device uses and multiply it by the rate shown on the electric bill to determine how much it costs you.
