How much does a 72-hour emergency kit cost?

A basic 72-hour kit for a family of four costs between $150 and $200. A premium kit with high-quality gear runs $350 to $500. The premium version lasts longer, performs better under stress, and requires less frequent replacement.

How often should I update my emergency kit?

Review and update your kit every six months. Check all expiration dates on food, water, batteries, and medications. Replace anything used or expired. Set a recurring calendar reminder — January and July work well.

What is the difference between a 72-hour kit and a go-bag?

A 72-hour kit is your comprehensive three-day supply system. A go-bag is a portable, grab-and-go version — a single backpack per person with the most critical items — designed for evacuation. Ideally, you have both.

Should I buy a pre-made emergency kit or build my own?

Building your own is almost always better for families. Pre-made kits are designed for generic needs and won't include your family's specific medications, document copies, comfort items, or food preferences.

What should I put in a 72-hour kit for kids?

Each child should have their own small backpack with a flashlight, water bottle, snacks, one comfort item, activity supplies, glow sticks, and a laminated emergency contact card. Update children's kits every three months.
