RoHS Compliance Coverage at 99% target rohs coverage rate: a worked example

What does the result look like when target rohs coverage rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when rohs compliance coverage in product compliance, labeling and certification needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Parts confirmed RoHS-compliant: 8 count (unchanged)
  • Total parts in the BOM: 250 count (unchanged)
  • Target RoHS coverage rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Rohs compliance coverage rate = rohs compliance coverage count ÷ total rohs compliance coverage population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for rohs compliance coverage rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for rohs compliance coverage gap to target.
  • At this operating point the engine returns 8 count for rohs compliance coverage count.
  • At this operating point the engine returns 250 count for total rohs compliance coverage population.

How this compares with the baseline

  • Against the tool's baseline example, where target rohs coverage rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target rohs coverage rate is genuinely sustained, not just peaked for a shift. It measures documentation coverage, not actual chemical compliance — a part counted as covered is only as trustworthy as the declaration or test report behind it.
