How make-or-buy works
Why does making create extra stock?
The target is rounded up to complete production batches, so planned output can exceed the quantity needed.
Is surplus profit?
No. It is inventory produced with material cash already spent; final profit depends on selling or using it.
Does this include wages and logistics?
Only when they are explicitly entered in a wider model. This calculator labels its current scope as materials only.
