When will my formula run out?
Two dates. When the tins you have will be empty, and — the one that actually matters — the last day you can order and still have formula in the house.

Put it on this week’s list. Still comfortable, but not for long.
310 fl oz of prepared formula left, at 30 fl oz a day for that age band. Order-by is the run-out date minus 3 days of delivery and a 3-day buffer.
Two to three days in normal conditions, longer over a holiday weekend.
At this rate you are getting through about 4.4 tins a month. What that costs.
Runs in your browser. Intake follows AAP guidance and is an average, so treat the dates as a prompt rather than a promise — a growth spurt will move them.
Why the second date is the one to write down
Running out is rarely the problem. The problem is noticing you are about to run out on a Sunday night, on a formula that takes a week to arrive. A parent buying a US shelf brand can afford to be careless about this. A parent importing from Europe cannot, and nothing on the tin tells them so.
| How you buy it | Lead time assumed | Why |
|---|---|---|
| On a shelf near me | 1 day | Same or next day. The only route where running low is a minor inconvenience. |
| US online order | 3 days | Two to three days in normal conditions, longer over a holiday weekend. |
| Imported from Europe | 10 days | Five to ten days when everything goes right, and customs can add more. This is the route that turns a small miscalculation into an emergency. |
Every lead time here is the pessimistic end of the range, and a 3-day buffer sits on top. Being told to order four days early costs nothing. Being told to order two days late costs a night in a pharmacy buying whatever is on the shelf, which is how unplanned formula switches happen.
What it cannot know
- Growth spurts. Intake is an average from AAP guidance. A baby in a spurt will empty a tin faster than this predicts, so treat the dates as a prompt to check rather than a promise.
- Which shelf your brand is on. Several European formulas reach US retail under FDA enforcement discretion and behave like domestic brands. Our records do not capture that reliably, so we assume the slower route unless you tell us otherwise.
- Stockouts. A lead time assumes the product is in stock. During a shortage it is not a lead time, it is a hope. See the shortage navigator.
- Whether you should stockpile. Buying months ahead worsens shortages for everyone and risks the tin expiring. Two to four weeks of buffer is the sensible band.
