Guidance

Household Emergency Planner:

Everyday calculators help make quick decisions more reliably. The right unit, period and base value are essential.

How to use the result better

  • Clarify the base value first.
  • Check unit and period: per day, month, year, net or gross.
  • Calculate a second variant for plausibility.

Common mistake

Many errors come from swapped base values, mixed units or wrong periods. The result may look correct but answer the wrong question.

Why is the unit so important?

A wrong unit or period immediately changes the result and can lead to wrong decisions.

How can I quickly check the result?

Calculate a second variant or estimate roughly in your head. Large differences become easier to spot.

Formula

How the result is calculated

Basic preparedness = people × period × base needs for water, food, hygiene, lighting and personal requirements

Example

Worked example

For 2 adults, 1 child and 7 days, the planner shows water first, then shelf-stable food, hygiene, lighting, medication and household-specific notes.

FAQ

Frequently asked questions

Why does the planner not use supply boxes?

Supply boxes are too abstract. Concrete amounts for water, food, hygiene, medication and lighting are more useful in everyday planning.

What matters most during a power outage?

Lighting, batteries, power banks, radio, water, important medication and a safe cooking option are usually among the most important basics.

Is this an official emergency plan?

No. It provides calm guidance for private households and should be checked against official recommendations and personal requirements where needed.
