What the data says
- Our forecast for the next 12 months (21,310 pc) is +10.1 % above what we called off in the last 12 months (19,360)
fc:340010@2026-09. More volume is worth something to the supplier: our agent cites this as its volume argument. - Single source: only Dichtungswerk Ravensteiner GmbH is on the source list. Walking away is costly.
- P10: the coverage trap. Covering less than 23,400 pc a year for 2 years costs up to €511,377 more than buying at today's price (16,379 a year for 12 months); full coverage (23,400 for 24 months) avoids it. A lower price only wins if it saves more than that.
Demand
What we ordered per month (by requested date) for the last 24 months, and the latest forecast for the next 12. The case's need per year is usually the latest forecast.

Coverage
The brief's formula: years = min(contract months ÷ 12, horizon); covered = min(volume, need) × years; uncovered = need × horizon − covered, bought at fallback × (1 + risk).
Need 23,400 pc a year over 2 years = 46,800. Whatever the deal does not cover is bought later at the fallback price €37.36 + 25 % risk = €46.70 (today: €29.89). Each cell: units left uncovered, and what they cost on top of buying them at today's price.
| Volume a year | 12 months | 24 months | 36 months |
|---|---|---|---|
| 16,379 pc | +€511,377 30,421 uncovered | +€236,046 14,042 uncovered | +€236,046 14,042 uncovered |
