Food Storage Inventory
Keep a count of your stored food, see how many days it feeds your household, and catch what is about to expire.
Nothing yet. Add what is on your shelves: a can, a bag of rice, a box of pasta.
This tool keeps a count of the food you have stored (cans, sacks of rice, boxes of pasta, jars) and answers the question that matters in an outage, a storm, or a stretch of tight weeks: how long would it feed us? It works it out by calories, warns you before anything expires, and keeps everything in your browser, on this device.
How the count works
For each item you record how many units you have and how many calories are in one unit. The tool multiplies them, adds up every item that has not expired, and divides the total by what your household eats in a day: the number of people times the calories each person needs. Twenty cans at 400 calories each and two bags of rice at 3,600 calories make 15,200 calories. At 2,000 calories a day for two people, that is 3.8 days, which the tool shows as 3 days: it counts whole days, so it never promises a meal you do not have.
An item with no calorie figure, like spices or a jar of stock cubes, is listed but left out of the count, and the summary names it. Servings can be recorded too and are shown beside each item, but they do not feed the total. A serving is whatever a label says it is, and a two-serving can of soup can still be only a few hundred calories.
Expiry warnings
Give an item the date its soonest unit expires and it appears under Expiring soon once it is within the warning window, 30 days by default. Anything past its date is shown as expired and left out of the days of food, so the total is what you could eat today. Many shelf-stable foods keep well past a "best before" date, so a warning is a prompt to use it or check it, not to throw it away.
Rotating your stock
The usual advice for a home food store is to eat what you store and store what you eat: cook from the oldest stock and replace it as you go, so nothing quietly expires at the back of a shelf. Sorting by expiry is what the warning list is for. When you use something, lower its quantity; when you buy more, raise it, or add the new batch as its own item with its own date.
Private by design
Your inventory is stored in your browser's own database on this device. Nothing is uploaded and there is no account, and the page works offline once it has loaded. Clearing this site's data in your browser deletes the inventory, so a list you rely on is worth keeping a note of too.
How is "days of food" worked out?
It adds up the calories in everything you have that has not expired (quantity × calories per unit), then divides by what your household eats in a day: the number of people × the calories each needs. Items with no calorie figure are listed but not counted, so the answer never assumes food it cannot measure.
Why calories and not servings?
A serving is whatever the label says it is: a can of soup might be two servings and still be only a few hundred calories. Calories add up across very different foods, so they answer "how long will this feed us" honestly. You can still record servings per unit, and they are shown beside each item.
Does expired food count?
No. Anything past its expiry date is left out of the days of food and listed under the warnings, so the total is what you could eat today. Many shelf-stable foods are still safe past a "best before" date, so check before you throw anything away.
How many calories does a person need a day?
About 2,000 is the common planning figure for an adult, and it is the default here. Active adults need more and children less, so set the figure for your household, or plan with a little extra.
Is my inventory uploaded anywhere?
No. It is stored in your browser on this device, works offline, and is never sent to a server. Clearing this site’s data in your browser deletes it.
