Wafer & Unit Cost Calculator

Turn a wafer run into a per-chip cost. Combine dies-per-wafer and yield with packaging and test cost to get an estimated unit cost, then apply a target margin for a suggested price — useful for early ASIC budgeting and quotes.

Unit cost = wafer cost ÷ net die + packaging + test. Price applies the target margin as markup. Wafer and packaging/test costs are illustrative — confirm with your foundry and OSAT before quoting.

COST ANATOMY

Where the unit cost actually lands

Most early budgets forget packaging and test. This illustrative split shows why wafer $/die is only part of the story — and why the calculator below matters for a real quote.

Wafer $/die is usually the largest slice; packaging and test scale with pin count and complexity. Model your own with the calculator.

The cost stack

  • Wafer $/die = wafer cost ÷ net good dies (gross DPW × yield).
  • Unit cost = wafer $/die + packaging + test.
  • Price = unit cost × (1 + target margin).
