72 hours. That’s how long Ready.gov says you should be able to survive on your own with your own food, water and supplies after an emergency.

The good news? You don’t need a big budget. Ready.gov also notes that most kit items are inexpensive and easy to find.

Here’s how to build an emergency kit on a budget, one small shopping trip at a time. I’ll show you what to buy first, where to save, and what to skip!

What an Emergency Kit Really Needs (and What It Doesn’t)

An emergency kit is just a set of basic items your household may need in a crisis. Skip the fancy gear and start with the basics.

FEMA’s recommended basics include water, non-perishable food, a flashlight, a first aid kit and a battery-powered or hand-crank radio.

That’s it. Everything else is a nice extra.

Step 1: Shop Your Home First

Before you spend a dime, walk through your house with a pen and paper. You probably already own more than you think.

One news report on the Ready.gov basics suggests looking at what you already have, then checking thrift shops and sales for the rest.

Write down what’s missing. That becomes your shopping list.

Step 2: Start With Water (It’s Cheap and Critical)

Water comes first. Ready.gov’s rule is one gallon per person per day for drinking and sanitation, for at least three days.

So a family of four needs about 12 gallons. Add a little at a time, a few jugs each week.

If you ever run out, the CDC explains how to make water safe. Boil it for 1 minute (3 minutes above 6,500 feet) or disinfect it with bleach as directed.

Step 3: Add Food You Already Eat

You don’t need freeze-dried buckets. Just buy a few extra cans and boxes of food your family really eats each time you shop.

Think foods that need no cooking, or very little. And don’t forget a manual can opener!

Ready.gov says to keep canned food in a cool, dry place and replace expired items as needed. Rotating what you buy keeps money from going to waste.

Curious about stretching your food without electricity? Learning non-electric preservation can be worth a look.

Step 4: Light, Power and Communication

This is where a few dollars go a long way. A couple of flashlights, a radio and extra batteries cover most needs.

Skip the candles. Ready.gov advises using flashlights instead because of the fire risk.

The FEMA list also includes a phone charger with a backup battery and local maps. Print a paper map, since phones can die.

Step 5: First Aid, Medications and Hygiene

Health basics are a smart place to spend a little. FEMA’s list includes moist towelettes, garbage bags and plastic ties for sanitation.

Do you take temperature-sensitive medicine like insulin? Ask your pharmacist about an emergency plan, and see the FDA’s guidance on insulin storage.

Step 6: A Simple Week-by-Week Shopping Plan

Here’s the part that makes it affordable. Spread your purchases over a month, and your wallet barely notices.

Common budget mistakes? Buying a pre-made kit you don’t understand, skipping water, and storing everything in one hard-to-reach spot.

Ready.gov also suggests keeping a smaller kit in your car, in case you’re stranded.

Beyond the Kit: Low-Tech Skills That Cost Little

Supplies run out. Skills don’t. That’s why some beginners also look at a low-tech skills program like BlastProof: David’s Shield.

According to the sales page, it’s $67 with a 60-day money-back guarantee. It covers topics like food preservation, water, heat and light, and home security.

I haven’t read inside the guide, and it isn’t a replacement for a real kit. Read my full David’s Shield review to decide if it fits your budget.

One gallon per person per day for at least three days, according to Ready.gov.

Conclusion: Start Small, Keep Going

Learning how to build an emergency kit on a budget is mostly about patience. Shop your home first, then add water, food, light, first aid and documents, a little each week.
