Food Storage Calculator

Know exactly what your family needs. Before you need it.

Food Storage Calculator turns "we should be more prepared" into a concrete plan. Tell it how many adults and children you're covering and for how long, and it computes your household's daily calorie need and translates it into real quantities: grains, protein and legumes, vegetables, fruit, fats, dairy, sugars, and water at one gallon per person per day.

From plan to pantry

Calorie-based, not guesswork. Standard long-term storage targets by default, adjustable per adult; children are counted as a configurable fraction of an adult ration. Every quantity rescales when you change the target.
Any coverage window. From a 72-hour kit to a full year. Plan in days or months.
Shopping lists in one tap. Turn any plan into a shopping list. With Pro, compare it against what you already have so the list shows only what's missing, and export it as a PDF for the store.

Pro: track what you have, see what's missing

Saved plans: keep household plans and revisit them anytime
Inventory tracking for what's already on your shelves
Gap analysis: exactly what you're still short, item by item
Expiration and rotation reminders so nothing goes to waste
PDF export for shopping lists

The calculator itself is free, forever. Pro is a monthly subscription or a one-time lifetime purchase.

Private by design

No account. No analytics. No ads. No tracking. Every plan and every inventory item is stored locally on your device. We don't have a server that could see your data. See the Privacy Policy.
