You know you can save money by investing in efficient Energy-Star-rated appliances, kind of the same way that you know shutting off the water while you brush your teeth saves water. But in either case, it's hard to quantify exactly what you're saving, especially when you factor in the extra cost of buying and installing a new appliance. Wouldn't it be great if there was some easy to use spreadsheet that can tell you how much YOU personally stand to gain from making the switch? You see where we're going with this? Yep, keep reading.

It turns out calculating your individual savings is super easy, thanks to the US Department of Energy's Energy Star website.

They've already set up all of the calculations for you on a downloadable Excel spreadsheet, tailored to each individual appliances. Here's how you do it:

1. Head to and find the "Find Energy Star Products" page. Then, click on the product you're considering upgrading for money savings.

2. Download the "Savings Calculator" spreadsheet on the right-hand side of the product page.

3. Gather up your latest utility bill and start filling in the values in the gray boxes at the top (red) section of the spreadsheet. You'll need numbers for your electric, gas and water billing rates, plus a general knowledge of how much you personally use the appliance.

If you're comparing a specific Energy-Star model, you can enter it's purchase price for an accurate estimate of savings. If not, Energy Star has an average value filled in for you already.

4. The rest is easy! Just look inside your spreadsheet's green box to determine how much you'll save in utilities each year by switching to an efficient appliance. Plus, the spreadsheet gives you an estimate of how long it will take to recoup the purchase price of your Energy-Star-rated gear. Awesome!
