Click calculate to find out the electricity cost of a single incandescent light bulb running at **60 Watts** for **5 hours a day @ $0.10 per kWh**, keep in mind you can edit the numbers in the calculator.

**Hours Used Per Day:** Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5)

**Power Use (Watts):** Enter the average power consumption of the device in watts.

**Price (kWh):** Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents. To find an exact price check your electricity bill or take a look at Global Electricity Prices.

Incandescent light bulbs have an average lifespan of 1000 hours or 41.6 days running 24/7. While comparable CFL light bulbs last an average of 9,000 hours or 375 days running 24/7 and an LED light bulb lasts 50,000 hours or 2,083 days. Incandescent light bulbs use the most energy from the 3 technologies, we highly recommend you take a look at the CFL light bulb calculator to see what a huge cost and energy saving difference switching to CFL or LED lighting can make.
