If you run a 100 watt bulb for 10 hours you would 1 kilowatt hour (kWh). The cost of electricity varies by location usually. Mine even has a sliding scale based on the usage and goes from $.08 to $0.25 per kWh. Look at your electric bill to see if it shows a rate per kWh. If it does not, divide the dollar amount of your bill by the total kWh used to get a rate per kWh. That will be the cost to run a 100 watt bulb for 10 hours.
Rather than calculating KWh's, and getting out your power bill or calling the Public Service Commission - there's a 'rule of thumb' (2007 numbers) - a 100 Watt light bulb costs about 100 dollars per year if left on continuously....a typical 1200 watt heater will cost you 100/month if used heavy in the winter months.... (takes into account increased startup current, on/off time(duty cycle) and left set at reasonably warm temp day/night).
simple a dollar/watt/year!...
100W - $100/year, 200W - $200/year, 1200W=$1200/year

∙ 14y agoFind out what your electric company charges you per kw hour. Now kw =1000 watts, so say you pay .12 per kw hour. A 100 watt light bulb is 1/10 of 1000 so divide .12 by 10. This would mean you pay .012 cents to run a 100w light bulb per 1 hour. Or .12cents for 10 hours

∙ 9y agoThat bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015

You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.
