MPW Cost Sharing Calculator
Split a shared multi-project wafer (MPW) cost across multiple designs. Each participant pays for the wafer area they occupy — the standard shuttle cost-allocation method — so you can quote or compare participation fairly before committing to a run.
Yield model
Participants
| Participant | Dies | Share | Cost | $/die |
|---|---|---|---|---|
| Design A | 633 | 33.2% | $3,985 | $6.30 |
| Design B | 2,545 | 33.4% | $4,005 | $1.57 |
| Design C | 1,327 | 33.4% | $4,010 | $3.02 |
| Total | 4,505 | 100% | $12,000 | — |
Cost is allocated by occupied wafer area (dies × die area), the standard MPW split. Totals reconcile to the entered wafer cost. Set defect density to 0 to allocate on gross dies only.

How the split works
- Each design's dies are estimated with the same Die-Per-Wafer model (scribe lanes and edge exclusion included).
- A participant's share = (their dies × their die area) ÷ (total occupied area).
- Their cost = wafer cost × share; cost-per-die = cost ÷ their dies. Totals reconcile to the entered wafer cost.
