Vary the uncertain input you can investigate
Choose a range for demand or a measured consumption assumption. Keep the currency, technical scope and delivered-cost boundary consistent across suppliers. A scenario is conditional on its inputs; it does not establish probability.
Use supplier-confirmed charges and the actual applicable tier rules. Missing freight or setup prevents a complete comparison. A low unit rate is not the same as low order cash commitment.
Understand a smooth crossing
For method A at EUR 100 fixed plus EUR 0.08 per good pack, and method B at EUR 800 fixed plus EUR 0.03 per good pack, costs cross at 14,000 packs. Below that quantity A costs less; above it B costs less under those constant rates.
At 10,000 packs the costs are EUR 900 and EUR 1,100. At 20,000 packs they are EUR 1,700 and EUR 1,400. This is an illustrative comparison of entered offers, not market pricing.
Treat discrete thresholds differently
MOQ, full bags, reel rounding and all-units price tiers can create jumps in cost. A supplier can become numerically cheaper at a discontinuity without the two costs ever being exactly equal.
The scenario panel samples up to 21 points and flags observed changes between them. It can miss narrower changes. Inspect the supplier tier threshold and rounded purchase quantity in any switch interval before choosing an order.
Common questions
Does the displayed range represent confidence?
No. It is a range of entered scenarios, not a statistical confidence interval or performance forecast.
Should I buy more to reach a discount automatically?
No. Compare the entire order commitment, usable surplus, storage and obsolescence exposure before ordering extra stock.
