Choose the matching volume target
Suppose you choose a target of 1,800 mlof one selected 500 mlconcentrate and already hold 200 mlof usable matching product. This is your stock target,not a recommended intake or a forecast of household use. The selected purchase unit supplies 500 mlof concentrate.
Subtract usable matching stock
The additional requirement is 1,600 ml. Four whole 500 mlunits add 2,000 ml,giving 2,200 mlin stock and 400 mlabove the chosen target. A 3.2 unit purchase is not assumed to be offered. The tool shows the extra volume caused by the complete purchase size.
Round the actual purchase unit
If you instead count whole matching offers,both target and held fields must use that count basis. Assembly’s 3 Lbox is a different selected unit and does not automatically become six independently packaged 500 mlpouches. Unknown quantities or diluted-drink targets are refused.
Read the surplus and remaining conditions
The result does not reserve stock,predict a use-by date or decide whether previously opened liquid is usable. Read the current storage and date instructions and confirm supplier limits before a large purchase. No personal cups-per-day or caffeine recommendation is calculated.
Apply the field to a purchase
For Assembly,a separate 2,500 mltarget with 500 mlheld would require one 3,000 mlbox,ending at 3,500 mland leaving 1,000 mlabove the chosen target. That is purchase rounding,not a reason to consume the surplus.
