Family Disaster Kit Cost Calculator

About the Family Disaster Kit Cost Calculator

FEMA recommends a 72-hour emergency kit, but the actual cost depends on household size, the level of preparedness, and whether the family is building the kit from scratch or filling only a few gaps in supplies they already own.

Water, food, medications, lighting, first aid, sanitation, and communication needs are the core categories. Comfort items, tools, and longer-duration supplies can raise the total quickly, while some equipment can be shared across the whole household.

This calculator estimates the cost by category so families can see the full budget and decide whether to build the kit all at once or spread the purchases across several trips without losing track of the total.

When This Page Helps

Emergency-kit planning is easier when the total is itemized instead of treated as a vague future purchase. This page helps families price the core preparedness categories so they can decide what to buy first and what level of readiness is affordable now.

How to Use the Inputs

1. Enter the number of people in your family (adults + children).
2. Select kit duration: 72 hours (basic) or 7 days (extended).
3. Select whether to include pets.
4. Review itemized cost by category.
5. Build gradually — prioritize water, food, and first aid first.

Example Calculation

Tips & Best Practices

• Build your kit gradually — add 2-3 items per grocery trip to spread the cost.
• Rotate food and water every 6-12 months to keep supplies fresh.
• Include copies of important documents (IDs, insurance, medical) in a waterproof bag.
• Keep $100-$200 in small bills — ATMs and credit card readers won't work without power.
• Pack a 3-day supply of any prescription medications and rotate monthly.
• Store the kit in an easy-to-grab location near an exit, not buried in a closet.
• Include comfort items for children: a favorite toy, coloring book, and snacks.

The 72-Hour Minimum

FEMA's 72-hour recommendation assumes that within 3 days, emergency services will reach most areas. However, events like Hurricane Katrina and recent wildfires have shown that help can take longer. Families in disaster-prone areas should consider 7-14 day kits.

Building the Kit Gradually

Don't try to build the entire kit in one shopping trip. Week 1: water and first aid. Week 2: food supplies. Week 3: lighting and communications. Week 4: sanitation and personal items. Week 5: documents and cash. This spreads the $200-$400 cost over a month.

Kit Maintenance Calendar

Set reminders every 6 months (when clocks change for daylight saving time): rotate food and water, check battery dates, update medications, review documents for accuracy, and check that clothing still fits growing children.

Frequently Asked Questions

• How much water should I store per person?

  FEMA recommends 1 gallon per person per day — half for drinking and half for sanitation. A family of four needs 12 gallons for 72 hours. Store in commercially sealed containers, not reused milk or juice jugs.

• What food should be in a disaster kit?

  Non-perishable, shelf-stable food that requires no cooking: canned goods (with a manual opener), granola bars, peanut butter, dried fruit, crackers, and ready-to-eat meals. Aim for 2,000+ calories per person per day.

• How often should I replace emergency kit supplies?

  Check and rotate every 6-12 months. Replace expired food, refresh water, check battery expiration dates, and update documents. Set a calendar reminder on the same date you change your clocks.

• Should I have a kit at home and in the car?

  Yes. A full 72-hour kit at home and a smaller go-bag in each car is the best approach. Car kits should include water, non-perishable snacks, blanket, flashlight, first aid, phone charger, and a set of warm clothes.

• What about baby/toddler supplies in the kit?

  Add formula/baby food (3-day supply), diapers (24+ per child), wipes, bottles, pacifiers, and a change of clothes. If breastfeeding, ensure the nursing parent's nutrition is prioritized. Include any infant medications.

• How do I include pets in our emergency plan?

  Add 1 gallon of water per pet per day, 3 days of pet food, medications, vaccination records, a leash/carrier, and bowls. This adds approximately $30-$50 to the kit cost per pet.
