To use the Food Storage Analyzer tool you first go to their website here. You go to the bottom of the page and click 'Try it out' - you don't even need an account. A new window will pop up where you can input your current food storage and any intended purchases. They have A LOT of products. Once you are done click the 'Calculate' button and your results will appear on the right side of the page. They tell you how many days of food storage you have (I had 10 for one person - not so good!) as well as a breakdown of percentages from fat, vitamins, etc.
It's a very cool, very easy to use, and very fast tool. And after all if we don't analyze what we have for food storage from time to time we really aren't being fully prepared. Good luck!
