Your household plan.
A few small steps today. Something useful to keep for later.
Your household
Who are you preparing for? Count each person once, including infants.
No allergy, diagnosis, medicine or other personal details are requested.
No diagnoses, medication names or other sensitive details needed. We add a planning prompt, not clinical quantities.
How the calculator works
The current Be Ready drinking-water formula is people × 3 litres × days. Four people over three days gives 36 litres. Stored water is subtracted, with a minimum gap of zero. Food uses estimated days remaining. Neither figure assesses individual clinical or dietary needs.
Completion gives equal weight to applicable checklist requirements and proportional credit for water and food. Optional and non-applicable items are excluded; broken equipment gives no credit. A score is not a guarantee of safety. Official guidance and checklist checked 27 October 2026. Tracking units and scores are independent ReadyEssentials choices.
