Take the 200 watts and multiply by the hours that the bulb is on and divide that number by 1000. This will give you the value kW that is to be used in a specific time frame. This is the form in which you are billed. Now take the cost that the utility company charges you for a kWh any multiply it the results of the first calculation.
An example your 200 watt bulb is on for 4 hours. This equals 800 watts divided by 1000 is equal to .8 kWh. If you are charged .09 cents a kWh it will cost you .8 times .09 equals .072 cents to operate the 200 watt bulb for 4 hours.
