Check it out and put in the stores from your personal pantry. It calculates how many days you have and the nutritional values. Some of the stuff I had to fudge on since I pack some of my own items but it was a good guestimate. It's only a basic idea, it does not figure in some of the grains I have in my store or oils. The cool thing is that if you use it now, you get entered to win a Years supply of legumes and grains.
Your right. I had to fudge a little also. There was no place to plug in eggs, milk, and meat from the chickens and goats. I does give you an idea though. My analysis said 186 days. If I add in the live stuff, I think we're getting close to a year. Time to get the canner and dehydrator in high gear.
