Todd,

There are a number of on-line calculators that may help you with overall planning. Most of them take number of adults/children and then plan based on a basic number of calories per day per individual. Just do a search on food storage calculators and you will probably bring up several of them.

Non food items will be more difficult to plan without any real data on consumption I imagine. Plus everyone is different of course, I know looking at Ben's list that we would blow through a few of his items in no time (like olive oil), but others might last us 5 years.

Interesting concept though, I look forward to learning from your experiences.
