Build a realistic 3-month food supply based on what your family actually eats each week. Enter your current weekly usage to generate a complete 13-week shopping list.
Unlike the long-term 1-year staples supply, the LDS 3-month supply is meant to mirror your family's normal diet. This makes it far more practical — you'll actually cook and rotate these foods. The simple formula is: track what you use in a typical week, then multiply by 13 to get your 3-month target. Enter your weekly usage below and we'll build your shopping list.
13-week supply based on your weekly usage. Round up when purchasing — it's better to have a little extra.
The Church of Jesus Christ of Latter-day Saints teaches a two-layer storage approach. The 3-month supply is the first and most accessible layer — it consists of foods your family already eats and knows how to prepare. This is different from the long-term staples supply (grains, beans, sugar) which requires learning new cooking methods and may not match current dietary habits.
The beauty of the 3-month supply system is that it integrates naturally with regular grocery shopping. Rather than a one-time bulk purchase, members are encouraged to gradually build up their supply and then continuously rotate it using the FIFO (first in, first out) method — always using the oldest items first and restocking from the back.
The 3-month supply doesn't require a dedicated pantry room. Most families find that organized shelving in a basement, garage, or closet is sufficient. A simple spreadsheet or even a clipboard list on the pantry door can help track what you have vs. what you need.
One practical approach: start by identifying 10–14 meals your family eats regularly that require only shelf-stable ingredients or minimal refrigeration. Make sure you always have 13 weeks' worth of those specific meals. This is more actionable than trying to account for every possible food category at once.
The 3-month supply consists of foods your family regularly eats — normal grocery items like canned goods, pasta, cereal, and bread. It mirrors your current diet and rotates continuously. The 1-year supply consists of basic long-term staples (wheat, rice, dried beans, sugar, salt) that can last decades but require more deliberate meal planning to use. The church recommends building both, starting with the 3-month supply since it integrates more naturally into daily life.
Small spaces call for creative storage: use the space under beds with low-profile storage bins, use furniture that doubles as storage (ottomans with interior space, hollow benches), install shelving in closets up to the ceiling, and use the space above kitchen cabinets. Canned goods can be stored in decorative baskets in living areas. The key is keeping a written inventory so you know what you have and where it is. Many apartment-dwellers successfully maintain a full 3-month supply with thoughtful organization.
Dedicated can rotation racks are convenient but not necessary. You can implement FIFO rotation on any shelf by simply placing new items at the back and taking from the front. Some people use a simple cardboard box as a "staging area" — new purchases go in the box and get moved to the back of shelves on a weekly grocery day. The most important thing is developing a consistent habit, not buying specialized equipment.
Yes, water is perhaps the most critical preparedness item. The minimum recommendation is 1 gallon per person per day for drinking and basic sanitation. For a 3-month supply this would be impractically large to store — instead, aim for at least a 2-week water supply (14 gallons per person) and also invest in a quality water filtration method (gravity filter, LifeStraw, or reverse osmosis) so you can purify additional water if needed. Store water in food-grade containers away from direct sunlight and replace it every 6–12 months.
A basic 3-month supply for four people typically costs $800–$1,500 depending on diet and food preferences. The most economical approach is to build it gradually — buy a few extra cans or packages each grocery trip rather than all at once. Many members spend an extra $15–$30 per week on storage items and have a full 3-month supply within a few months. Sales, store brands, and buying club memberships (Costco, Sam's) significantly reduce costs.
