Winter Storm Kit Cost: 4 People, 3 Days, $229 Total
On the defaults — 4 people for 3 days at $12 food a person a day plus $85 gear — a winter storm kit costs $229.00 in all, $144 food, $57.25 a person. This is the winter storm kit cost tool: people times days times food a person a day is the food, food plus gear is the total — a storm kit price tells you nothing until the household size and the days it must last are counted.
What does $229.00 mean?
It means 4 people sheltering for 3 days at $12.00 of food a person a day plus $85.00 of one-off gear cost two hundred and twenty-nine dollars in all, which is $144.00 for the food itself and $57.25 a person. The people count sets how many mouths the food must feed, the days set how long those mouths must be fed, the daily food figure sets how dear each person-day is, and the gear is added once on top: one more person adds $36.00 at the default days and food rate, while dearer gear lifts the total without touching the food maths at all. The only judgement is the daily food figure itself — tinned meals, water, snacks and pet food are not the same daily rate, and the rate actually spent per person per day is the only honest source for it.

Three things to check before you trust the number
First, check the people honestly: 4 people must be the household actually sheltering, not neighbours who might drop by — a person counted who never shelters adds $36.00 that was never spent. Second, check the days against the forecast: 3 days must be the outage the kit is built for, not the shortest storm on record — a 5-day outage built for 3 days runs out of food two days early, and the kit fails at exactly the moment it is needed. Third, check the gear against what you already own: $85.00 must be the gear still to buy, not a full kit bought twice — torches, batteries and blankets already in a drawer cost $0 here, because counting them again inflates the bill for kit already owned.
Worked example
4 people, 3 days, $12.00 food a person a day, $85.00 gear. Food: 4 × 3 × $12.00 = $144.00. Total: $144.00 + $85.00 = $229.00. Per person: $229.00 ÷ 4 = $57.25. In practice that means a household storm kit costs about fifty-seven dollars and twenty-five cents a head all-in, and the $144.00 food figure is the one to set against other kits, since gear is bought once and priced differently everywhere.
Every branch, checked
At 2 people instead of 4, the total falls to $157.00 — $72.00 food, $85.00 gear, $78.50 a person. At 6 people instead of 4, the total rises to $301.00 — $216.00 food, $85.00 gear, $50.17 a person. At 5 days instead of 3, the total rises to $325.00 — $240.00 food, $85.00 gear, $81.25 a person. At $150.00 gear instead of $85.00, the total rises to $294.00 — $144.00 food, $150.00 gear, $73.50 a person.
The reverses, worked backwards
The people behind $229.00 are 4: at 2 people the total is $157.00; at 6 people it is $301.00. The days behind $229.00 are 3: at 2 days the total is $181.00; at 5 days it is $325.00 — the days never touch the gear, only how much food the household must hold.
What the defaults assume
The defaults assume 4 people, 3 days of supplies, $12.00 food a person a day, and $85.00 of gear still to buy, for one household sheltering at home through one storm. They do not assume heating fuel, a generator, medication, or pet food beyond the daily rate — so treat $229.00 as the planning cost for 4 people for 3 days at $12.00 food a person a day plus $85.00 gear, and check it against your own shopping list before budgeting it as exact.
Who uses this
- A household getting ready for winter: the $229.00 is the figure to set against the monthly budget.
- Someone stocking up before a forecast storm: the food figure shows what the pantry run itself costs before gear.
- A parent of a larger family: the branches show how the bill moves with two more mouths or two more days.
- A renter in a first flat: the gear line shows what is still to buy once the food is counted.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the household actually sheltering, the days the outage may truly last, the true daily food rate, and whether the gear is still to buy. Real storms vary with length, appetite and what is already in the cupboard — so treat $229.00 as the planning cost for 4 people for 3 days at $12.00 food a person a day plus $85.00 gear, and check it against your own list before budgeting it as exact.
