Lots of companies sell packages of long term food storage with labels like “1 year supply,” but trying to compare those packages isn’t always apples to apples. It’s important to look at just how many calories you’re getting. Many only give 800-900 calories a day which should be considered bare minimum sustenance. It’s not enough to keep you strong or maintain a healthy weight. While the calculations are basic, this calculator allows your mind to go into auto pilot and does the work for you!
Check the description of the package you’re considering — most should give the total number of calories included, though some hide it in the fine print. You’ll need that information for the calculation.
