If you're a penny pincher, you probably want to know what decorating the house with Christmas lights will cost. Personally, I hate math, so anytime I can find someone else to do the work, I will.

Guess what? I found a website to do the work (even better than a live human). With the handy dandy Christmas Lights Electricity Cost Calculator, you can dodge the shock of your after holiday bill by simply inputting the required info and plan accordingly.

You'll need to know the price of your electricity and the type of bulbs in the light strings. Multiple types of lights? No sweat! They thought of that. They even thought of selling lights on their page. Pure genius.

I am just wondering if we would change the amount of lights if we actually saw the cost? Hmmm.
