Emergency supplies calculator (International): what your household needs for 3 days
The EU's Preparedness Union Strategy encourages households to keep essential supplies for at least 72 hours in an emergency. It sets no detailed quantities, so this general plan assumes 3 litres of water per person per day and about 2,200 kcal of food per adult per day. Choose your country for local guidance and shops.
We don't have guidance for your country yet, so this page uses the EU's general 72-hour baseline. If your country is listed, choose it for local guidance and shops.

Frequently asked questions
How much water should I store?
Your authorities' figure is shown above. Most authorities recommend around 2 to 4 litres per person per day, covering drinking and basic hygiene. Children, pregnant women and people in hot weather may need more.
How long should my supplies last?
The number of days differs from country to country, so we show the figure from your national authority. Even a few days of supplies make you far more resilient than none at all.
Do I need to buy everything at once?
No. Start with water, food and any medication you rely on, then add the rest over time. Check what you already have at home and rotate food before it expires.
