Where the deal's total cost comes from
Each term recomputed from the case file and the closing terms, the way the kit's cost.py does, and checked against the arena's breakdown for this run.
| Term | This deal, worked out | € | Arena |
|---|---|---|---|
Price units before the new price × current price + (committed − those units) × unit price | 8,000 units × €50.30 = €402,400 | €402,400 | ✓ |
Uncovered need (need × horizon − covered) × fallback price; covered = min(volume, need) × years | (8,000 − 8,000) × €55.00 = €0 | €0 | ✓ |
Fallback risk uncovered need × fallback risk % | €0 × 5 % = €0 | €0 | ✓ |
Payment terms spend × our interest rate × (reference payment days − payment days) ÷ 360 | €402,400 × 8 % × (60 − 45) ÷ 360 = €1,341 | €1,341 | ✓ |
Freight committed units × freight per unit for the Incoterm | 8,000 × €1.20 (FCA) = €9,600 | €9,600 | ✓ |
Late delivery late cost per day × max(0, lead time − lead time we need) | €0.00 × max(0, 35 − 35) = €0 | €0 | ✓ |
Quality committed × ppm ÷ 1,000,000 × (cost per defect − chargeback) | 8,000 × 650 ÷ 1,000,000 × (€0.00 − €0.00) = €0 | €0 | ✓ |
Tooling tooling paid once | €0 | €0 | ✓ |
Index clause spend at the new price × material share × max(0, |expected move| − deadband) × sign | no index clause = €0 | €0 | ✓ |
