Test Cost & Yield Calculator
Model the test line before you commit volume. Enter your ATE hourly rate, per-device test time, handler cost, volume and expected yield to see cost per device tested and — the number that actually hits margin — cost per good unit.
Use your ATE hourly rate (older platforms ~$200–400/hr, advanced SoC testers $1,500–3,000/hr), the per-device test time, handler/sorter cost and the expected good-unit yield.

Cost per good unit = (ATE cost + handler cost) ÷ good-unit yield, because you pay to test every device, including failures. A 5-point yield gain from 95% to 100% would cut cost per good unit by about 5.0% — the single biggest test-cost lever after test time.

WHY YIELD DOMINATES
You pay to test every die — including the fails
Test cost per good unit divides your total test spend by the good units only. Because every device is tested, a lower yield spreads the same ATE and handler cost across fewer shippable parts — which is why a few yield points often beat a faster handler.

These are industry reference ranges, not a quotation and not an offer.
- Every band on this page is deliberately wide. It is published so you can sanity-check whether a programme is realistic before you write to anyone — not so you can budget against it.
- Actual pricing moves with the season and with capacity. Foundry and OSAT utilisation changes month to month, and a window that is cheap in a soft quarter can be materially more expensive in a tight one.
- Mask, substrate, leadframe, gold, copper and tester-time costs all move independently of the node you chose.
