The other half of the answer

That is the target. How many days do you actually have?

Most pantries cover about three days once someone counts the real calories. Provision Planner counts yours against this exact goal: days covered, what expires when, and what to buy next.

Looking for the classic LDS food storage calculator?

The original church-era calculator that generations of families used is no longer online. The math lives on here: the button below loads the traditional Home Production and Storage staple targets (grains, legumes, fats, sugars, powdered milk, salt) for your household size, alongside the modern FEMA-based short-term numbers. Same stewardship, current tools. There is also a dedicated LDS year supply calculator with the staple table front and center.

Be prepared, not worried.

Worry is not a plan. Knowing is: exactly how many days your family is covered, what expires next, and what to buy this month. That is the whole product.

The next questions, answered

How much food and water does a family of 4 need for 2 weeks?

For 2 adults and 2 children over 2 weeks, this calculator's math comes to about 98,000 calories and 56 gallons of water, roughly $185 at typical grocery prices. Water follows FEMA's one gallon per person per day; food is sized by age group rather than a flat adult count, which is why a family of 4 needs less than 4 adult shares.

How much water should I store per person?

One gallon per person per day, per FEMA and Ready.gov: half for drinking, half for cooking and basic hygiene. Store at least a 3-day supply for evacuation, and two weeks per person at home where storage allows. Children, nursing mothers, illness, heat and pets all push the number up.

How many days of food should a household store?

Ready.gov's floor is a 3-day supply that travels if you must evacuate, and a two-week supply at home. This calculator sizes anything from 3 days to a year; most households start with two weeks and grow from there.

Is this food storage calculator free?

Yes. The calculator is free, with no account and nothing to install. Provision Planner, the app behind it, also has a real free plan that tracks what you already own and shows how many days it covers.
