Rare Earth Magnet & Motor Materials calculators

These 20 calculators follow sintered rare earth magnets from alloy powder through pressing, sintering, grinding, coating and magnetizing to packing, shipment and warranty. Enter counted, weighed and quoted values, compare each result with your own target or capacity, and download the same calculations in Excel.

What this hub covers

  • 20 calculators for magnet powder, sintering, grinding, coating, magnetizing, inspection, capacity, energy, packing, margin, supply and warranty.
  • Browse rare earth magnet & motor materials calculators for manufacturing planning, quoting, quality, capacity, and operations decisions.

Best calculators in this category

  • Powder Yield: Share of NdFeB powder lots passing particle size and oxygen limits, compared with your target.
  • Sintering Shrinkage: Green compact dimension that sinters to finished size plus grinding stock, checked against your die.
  • Magnetization Capacity: Good magnets a pulse magnetizer delivers from whole pulses in the scheduled hours, compared with demand.
  • Coating Yield: Share of coated NdFeB magnets passing adhesion, thickness and appearance checks, against your target.
  • Rare Earth Cost Sensitivity: Change in magnet batch cost from a swing in NdPr oxide price, in dollars and as a share of batch cost.
  • Scrap Recovery Value: Net value of a lot of NdFeB magnet scrap after reclaim fees and lot overhead.
  • Grinding Loss: Share of each sintered magnet blank ground away, the material it represents and its value, against your target.
  • Inspection Bottleneck: Daily load on magnet final inspection: station time needed against the station time your crews run.
  • Furnace Utilization: Share of available hours a magnet sintering furnace actually runs, against your target utilization.
  • Supplier Risk: Risk priority score for one rare earth supply failure mode, compared with your action threshold.
  • Capacity Gap: Gap between good sintered magnet capacity and demand, split into downtime and yield losses.
  • Quote Margin: Gross margin on a magnet order quote and the order price that meets your target margin.

Live market signals for this industry

  • The producer price index for primary nonferrous metals (a broad metals benchmark, not copper alone) stands at 566.01 (BLS, Sep 2026), up 46.1% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $14,473 per tonne (IMF via FRED, Sep 2026).
  • The U.S. has 5,397 electrical equipment and appliances establishments employing about 369,437 workers (Census County Business Patterns, 2023).

Category questions

  • Where do the default values come from? They are illustrative numbers for a typical job so the page shows a worked answer. Replace them with your own measurements, datasheets and quotes before you rely on a result.
  • Why do some results show a warning? A warning means the plan fails a limit you entered or one from a cited source, such as your target coating yield, die headroom or booked warranty reserve. The message states the gap and what to change.
  • Can I download the calculation? Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.
  • Why is a result blank? An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.
