Online LED Savings Calculator

Calculate the savings you could make by switching to LED lights around your house. The upfront cost of LED lights may be daunting but in the long run they really make up for in savings. The calculator below lets you capture in great detail all the lights you use around your house. It will use your electricity price (or uses a default) and replaces each incandescent light bulb with its equivalent LED.OnlineLED

After you’ve entered all the room information you can change additional parameters such as electricity prices, LED pricing and bulb longevity or simply scroll down to the Click here to see savings button. Don’t worry this won’t take you to some other page asking for your firstborn’s name. The savings will appear under the button. It shows you how much you will save over the time of the plan and breaks it down to savings per month. It also gives you the upfront cost associated with switching to LED. Upfront cost and replacement costs are included in the savings.

If you find entering all rooms may be too daunting, simply enter the bulbs for one room and the hours they run. You’ll find the saving there alone may be worth entering all rooms (you can click the “see the savings” as often as you like).
