Official guidance, shown honestly: UK Be Ready: 3 days. Germany: 10 days if possible, 3 days already helps. EU: 72 hours. US: several days. 90 days is a personal choice, NOT an official order. No government has ordered a 3-month stockpile in this research.

Rates below are the planning rates used. Change any rate and the totals update. Rice, oats, beans, oil, salt, sugar and powdered milk are per adult-equivalent per day; canned items are cans per adult-equivalent per day.

Assumptions and formula

Adult-equivalent factors for food: adult 1.0, teen 0.9, child 0.6, toddler 0.4, infant 0.0 (infants get milk/formula, not the solid basket). For drinking water: adult 1.0, teen 0.9, child 0.6, toddler 0.4, infant 0.3, plus 1 extra litre per day if pregnant/breastfeeding is ticked, and +0.2 food-equivalent for the mother. Drinking water = 3 litres × water-equivalents × days, shown separately from food and from cooking/hygiene water, which is not included. Each food total = rate × food-equivalents × days. Infant milk total = infants × parent-entered ml per day × days ÷ 1000, in litres.

Infant disclaimer: Infant feeding is medical. Use the milk amount your baby actually uses, or your doctor's guidance. This tool does not prescribe infant feeding.

Hand-test table — verified against the formulas above

These results were calculated from the default rates, with no rate changes, and must match the calculator when the same inputs are entered.

Test case	Rice	Oats	Beans	Veg cans	Meat cans	Oil	Salt	Sugar	Powdered milk	Drinking water
1 adult, 3 days	0.90 kg	0.30 kg	0.45 kg	0.99 cans	0.66 cans	0.14 L	0.03 kg	0.10 kg	0.10 kg	9.00 L
1 adult, 90 days	27.00 kg	9.00 kg	13.50 kg	29.70 cans	19.80 cans	4.05 L	0.99 kg	2.97 kg	2.97 kg	270.00 L
5 adults, 90 days	135.00 kg	45.00 kg	67.50 kg	148.50 cans	99.00 cans	20.25 L	4.95 kg	14.85 kg	14.85 kg	1350.00 L
8 adults, 30 days	72.00 kg	24.00 kg	36.00 kg	79.20 cans	52.80 cans	10.80 L	2.64 kg	7.92 kg	7.92 kg	720.00 L
2 adults + 1 infant + 1 child + 1 teen, 30 days (infant milk at 750 ml/day)	31.50 kg	10.50 kg	15.75 kg	34.65 cans	23.10 cans	4.72 L	1.16 kg	3.47 kg	3.47 kg	342.00 L, plus infant milk 22.50 L

Note on the mixed case: food-equivalents = 2×1.0 + 1×0.0 + 1×0.6 + 1×0.9 = 3.50. Water-equivalents = 2×1.0 + 1×0.3 + 1×0.6 + 1×0.9 = 3.80, so water = 3 × 3.80 × 30 = 342.00 L. Oil is 4.725 before rounding and displays as 4.72 after the calculator's 2-decimal rounding; all other totals are exact to 2 decimals from the rates above.
