This form should give you an idea of the volume of food you may need. You will need to use your own judgment when making decisions as to how much food to buy. Fifty pounds of oats may be enough unless you plan to use it for more than making oatmeal for breakfast, so take into consideration how your family consumes these products.
Use the following calculator to figure the minimum food storage amounts for your family for a year. These are only recommendations. You will need to determine the needs of your own family.
*Flour: If you regularly bake bread and other foods containing flour, the amount calculated may not be even close to enough, unless you have a grinder to make your own flour and have lots of wheat.
**Based on survival rations of 1/2 gallon per person per day. More may be needed for cooking and bathing.
