Choose the unit first
The target tool can count complete retail offers or declared matching bars. For selected TREK,the retail offer contains three bars. For the selected Grenade and Fulfil singles,it contains one. Unknown mass,protein grams,servings or mixed flavours are not silently converted into matching bar counts. The target comes from the buyer,not a predicted daily intake.
A13-bar example
If the chosen target is13 matching TREK bars and two are already held,11 additional bars are wanted. Four complete3-bar packs add12,leaving14 total and one above the chosen target. The tool shows both the whole-pack order and the surplus. It does not recommend eating the extra bar or claim that a retailer can supply the calculated quantity.
A no-surplus example
For a chosen target of10 matching TREK bars with one already held,three packs add nine and reach10 exactly. If the target is already met,the required order is zero. More held stock never creates a negative order. Those cases make the tool useful for avoiding an unnecessary purchase as well as planning a positive one.
Count only matching usable stock
Do not count another flavour or a different bar size as automatically equivalent when the target is defined for the selected SKU. Check actual packaging condition and dates rather than counting every item in a drawer as usable. The calculator does not inspect stock,extend dates or determine food suitability. Changing the selected product clears the target to reduce accidental carry-over.
Keep the boundaries clear
Whole counts from zero to one million are supported for arithmetic;blank,negative,fractional,exponent and larger inputs are rejected. That upper bound is not a supplier limit or a recommended purchase volume. Before ordering,confirm the current selected pack,actual stock and local price. No personal or health data are entered or transmitted.
