CFL Light Bulb Savings Calculator app for iPhone and iPad

"...The app is great as it makes it clear what a no brainer it is to switch to CFL bulbs." - Brendan, www.PlentyWays.com

Our calculator is designed to instantly give you an estimated annual cost savings based on the average kilowatts per hour your state charges.

To use our CFL Savings Calculator, simply select three values from the picker list.
1. Your location (if you are outside the United States, please select "Custom Location").
2. Number of light bulbs you would like to convert.
3. Wattage of the current light bulbs you are changing out.

Your Done!

Our calculator will instantly give you an estimated annual cost savings based on the average kilowatts per hour your state charges.

Also, Weve added last years EIA data to give you a year over year rate percentage change.

Additionally, you can also edit:
• Cost of the incandescent bulbs you paid for
• Cost of the CFL bulbs youve purchased or plan to purchase
• Custom kilowatts per hour for your location outside of United States.
• Average daily usage in number of hours
• (New Feature!) Users can now adjust the conversion ratio between incandescent and the CFL bulb


No internet connection required! The app will save all the data in your phone so you can run this app any time anywhere.

For Users Outside of the United States:
Please select "Custom Location" from the front picker list then click on the little "i" icon at the bottom right of the screen to go to the back side of the calculator. Here, you will need to enter the cost of an average kilowatt-hour (kWh) of electricity in the location where you reside (this data should be available in your monthly utility bill.) Then, click "Done" at the top of the screen and your calculated savings will be displayed accordingly.

Lastly, thank you for going green.
