Frequently asked questions

Is 2,000 calories per person per day enough?

It is the standard planning baseline, and it is what this page uses: 180,000 calories total for 3 people over one month. Young children need less, teenagers and adults doing physical work need more. If your household skews either way, size up or down one step with the selector above, or let Provision Planner calculate it per person.

Why so much water?

One gallon per person per day is the FEMA minimum for drinking and basic hygiene, which is where the 90 gallons comes from. Plan for more in hot climates, for pregnant or nursing family members, and for pets. Water is the item families most often undershoot.

How do I keep all this from expiring?

Buy foods your family already eats, store the newest purchases at the back, and eat from the front. The Lasts column above shows how long each item keeps. Provision Planner tracks the dates for you and warns you before anything expires.
