The target is supplied by you
The stock tool accepts a chosen whole number of matching packages or whole declared millilitres. It does not choose a child’s application amount or forecast stock days. Existing usable stock must actually match the selected product, formula and condition before it is included.
A 250 ml example
For a chosen 600 ml matching Aveeno stock target with 100 ml already held, the gap is 500 ml. Two 250 ml packages meet that arithmetic target exactly. The result is two packages, not an instruction to buy enough lotion for a fixed number of days or children.
A 75 ml rounding example
For a chosen 200 ml matching Weleda target with 25 ml already held, the gap is 175 ml. Three 75 ml packages add 225 ml and leave 250 ml in total, fifty above target. Two packages would leave 175 ml and fall short of the chosen target. This counts declared stock, not measured remaining contents.
Practical limits
Inputs must be nonnegative whole numbers up to one million. Blank, fractional or negative entries remain unresolved. Actual expiry, condition, seller limits and stock availability can prevent an arithmetic plan from becoming an order. No order or payment is submitted.
