How we count
CrisisCart compares what you keep at home with common supply norms. Here is where every number comes from and how the percent is built.
What the percent means
The percent shows how much of the norms your supplies cover. It is not a forecast and not a guarantee of survival or safety: real needs depend on health, season, climate and the situation itself.
Six scenarios
Readiness is counted separately for six situations: a power cut, no tap water, staying at home, evacuation, cold without heating and a radiation alert. Each one is a list of needs: water and food per person per day, items per household (a torch, a radio, a first-aid kit), supplies for the length of the scenario (batteries, fuel) and simple checks (cash at home, copies of documents, a meeting place, a contact list).
From needs to a percent
Each need counts for at most 100% of what the scenario asks, so a mountain of one thing cannot hide the lack of another. Critical needs (water, food, light, warmth, the grab bag) weigh three times as much as minor ones, important ones twice as much. Overall readiness is the average of all six scenarios. “Days covered” is the smaller of two numbers: how long the water lasts and how long the food lasts for your household. Expired food and water are not counted.
A power cut, no water, staying at home and cold last as long as the goal you set. A radiation alert lasts 14 days, or longer if your goal is longer. Evacuation lasts 3 days and counts only what is packed in the grab bag.
Water
Where a national civil protection guide gives one number for water per person per day, we use it for everyone in the household. Where it does not, we use the reference values of the European Food Safety Authority (EFSA): 2.5 litres for adults, 2.1 for children and 1 litre for infants.
| Country | Litres per person per day | Source |
|---|---|---|
| Germany | 2 | National guide |
| Austria | 1.5 | National guide |
| Switzerland | 3 | National guide |
| Serbia | 2.5 | EFSA reference values |
| Sweden | 3 | National guide |
| Finland | 2 | National guide |
| Norway | 2.5 | EFSA reference values |
| Poland | 2.5 | EFSA reference values |
| Netherlands | 3 | National guide |
| Estonia | 3 | National guide |
| Latvia | 3 | National guide |
| Lithuania | 2.5 | EFSA reference values |
| Another EU country | 2.5 | EFSA reference values |
Food
Calories come from the EFSA average requirements for a low activity level: about 2,340 kcal a day for an adult, 1,670 for a child and 740 for an infant. National guides do not give one calorie figure we could use for every country, so this part is the same everywhere.
Our own values
For three needs no official guide gives a number. We set them ourselves and keep them modest:
- Pets: one day of food and water per pet for every day of the goal. You tell the app how many days a pack lasts.
- Toilet paper: one roll per person every five days.
- Coffee or tea: one serving per adult per day. Not a survival need, but it keeps everyone calm.
When we checked
All sources were last checked on November 14, 2026. When a guide changes, we update the number and this date.
