How to Use the Payback Calculator

Have you ever wondered if that new gadget or new light bulb is worth it? The Payback Calculator helps you determine this by comparing the cost of the product to your electric bill savings. Simply plug in the cost of the improvement (i.e. light bulb, Smart Strip, etc), your KwH price (typical values are 8 to 13 cents, but can range higher), the amount of power saved in watts, and the duration of time each day you will be saving.
