Die-Per-Wafer (DPW) Calculator — Fast Estimates for Chip Costing
A die-per-wafer calculator quickly estimates how many chips fit on a silicon wafer—vital for unit cost, yield planning, and tapeout decisions. Use our tool for early planning, then confirm final DPW with your foundry (they account for scribe lanes, PCMs/test structures, seal rings, and edge rules).
Why it matters
Drives cost per chip and business cases
Anchors gross vs. net die assumptions for yield models
Speeds feasibility and vendor comparisons
How it works (no install)
Enter wafer diameter (mm)
Enter die size (L×W or area)
Optionally add scribe width → instant gross DPW & utilization
Any wafer size
From 2-inch legacy/MEMS to 300 mm and beyond—just enter the diameter.
Who uses it
Program/finance teams, procurement, design & operations, and pre-sales—anyone who needs quick, defensible estimates.
