Emergency Water Storage Calculator

Last Updated: March 19, 2021

Use the handy calculator below to figure out what you need for your family’s emergency water stockpile.

Fema, Ready.gov and most other reputable sources recommend stockpiling the following amounts of water per day:

  • Drinking – 0.5 gallons per person
  • Washing\Cleaning – 0.25 gallons per person
  • Cooking – 0.25 gallons per person

Note these amounts are a bare minimum for basic survival, most American households use 300 gallons of water per day!

We recommend aiming for a 30 day supply, but don’t get overwhelmed, start by stockpiling enough water for 3 days, then work your way up to a 2 week supply and finally a months supply.
