Build Your Emergency Kit Over Time: Week-by-Week Plan
You don't need to buy a complete emergency kit in one purchase. Building gradually over 6–8 weeks, adding $5–15 per week, is more affordable and means you actually do it instead of indefinitely postponing a $150 purchase. This guide gives you a week-by-week schedule, ordered by impact so each purchase meaningfully improves your preparedness.
Last reviewed: 2026-03-01 · Based on Ready.gov, FEMA guidance
Week 1: Water (~$8)
The most critical resource first.
- Buy 6 one-gallon water jugscritical
3-day supply for 2 people. Grocery store. Do this this week — no other preparation matters as much.
- Write emergency contacts on paper (5 numbers)critical
Free. Takes 5 minutes. Do it now while reading this.
Week 2: Food (~$10)
No-cook emergency food.
- Peanut butter (2 jars) + crackerscritical
~$7. 3,000+ calories. No cooking required. Rotate into regular use every 6 months.
- Granola bars, 12-packcritical
~$3. Quick calories, long shelf life.
- Manual can opener ($1)critical
Useless canned goods without it.
Week 3: Light (~$10)
Power outages happen at night.
- Headlamp with batteries ($10–12)critical
Headlamp is better than a flashlight — hands-free. Energizer or Black Diamond models under $15 are reliable.
- Extra AA or AAA batteries for the headlamp ($3)
Week 4: Warmth ($5–8)
The cheapest life-safety purchase on this list.
- Emergency mylar blankets, 4-pack ($3–5)critical
2 oz each. Prevent hypothermia. Available at dollar stores, Walmart, or Amazon.
- Rain ponchos, 2-pack ($3–5)
Wet clothing dramatically accelerates heat loss. A poncho is your first defense.
Week 5: First Aid (~$10)
- 100-piece first aid kit ($8–12)critical
Walmart or Target. Look for: bandages (multiple sizes), gauze, antiseptic wipes, medical tape, tweezers.
- Pain reliever + antidiarrheal ($3–4)
Week 6: Communication (~$15–20)
- Power bank 10,000 mAh ($15–22)critical
Anker PowerCore 10000 (~$22) is reliable for years. Budget alternatives work for infrequent emergency use. Charge it monthly.
- Car charger and USB cable ($5)
- Print a regional mapcritical
Free. Print from Google Maps or your state DOT. Laminate at a library for $1.
Week 7: Extend Food & Water (~$12)
- Canned food: 12 cans (tuna, beans, soup)
~$10–15. Add to the pantry and rotate into regular meals. No separate storage needed.
- Extend to 14-gallon water total (+8 jugs)
~$5. One-week supply for 2 people.
Week 8: Shelter & Documents (~$15)
- NOAA hand-crank or battery weather radio ($20–30)
When cell service fails during a major storm, NOAA radio is the most reliable emergency broadcast source.
- Waterproof document pouch + copy key documents ($3–5)critical
Copy IDs, insurance cards, medication list. Put them in a waterproof sleeve in your kit.
- Cash: $60 in small bills (add to wallet, not the kit)critical
ATMs fail during power outages. Small bills matter — gas stations may not have change.
