Define matching stock first
The calculator uses a user-chosen number of matching unopened selected containers. Each shortlisted offer supplies one pump,one refill container or one jar. A partly used bottle or another scent is not automatically one matching unopened unit. Count exact supported purchase units instead of mixing cream and cleanser stock.
A simple worked case
If your chosen target is five selected Sea Minerals pump bottles and you already hold two matching unopened bottles,you need three additional selected offers. If you hold five or more,the purchase result is zero. This is arithmetic,not a recommendation that every home should own five bottles.
Bounds and invalid entries
Counts must be nonnegative whole numbers up to 1,000,000. Blank,negative,fractional,exponential and over-limit entries stay invalid. A maximum target and equal held stock still produce zero;there is no negative order. The result does not reserve stock or establish that a large real order can be fulfilled.
What is deliberately not forecast
No pump-dose assumption,household-size formula,cream application amount or storage-lifetime estimate converts stock into days. Product current labels and storage conditions remain separate checks. If a seller changes the package count or selected variant,update that actual record before treating it as matching inventory.
A specific purchase check
A target of zero with one million matching units held produces zero to buy,not a negative purchase or an assumed return. A target of one million with none held produces one million selected offers arithmetically. The bound tests establish software behavior;they do not say that any store will fulfill that quantity or that it is sensible stock for an individual.
