Cathode Active Material & Precursor Manufacturing calculator

Inventory Coverage Calculator

Estimate adjusted days of coverage for CAM, precursor, metal sulfate, lithium source, or dopant inventory using stock on hand, daily demand, and a safety multiplier. On-hand divided by daily usage, then divided by safety multiplier, gives a protected days of supply.

What this calculator does

  • Estimate adjusted days of coverage for CAM, precursor, metal sulfate, lithium source, or dopant inventory using stock on hand, daily demand, and a safety multiplier.
  • Use it when inventory coverage in cathode active material and precursor manufacturing is being sized for a buffer or safety stock review.
  • Turns usable battery-material inventory on hand, average daily material demand, safety coverage multiplier into a protected days of supply for inventory coverage in cathode active material and precursor manufacturing.

Formula used

  • Unadjusted coverage days = usable battery-material inventory on hand ÷ average daily material demand
  • Adjusted inventory coverage = unadjusted coverage days ÷ safety coverage multiplier

Inputs explained

  • Usable battery-material inventory on hand: Use released CAM, precursor, lithium source, metal sulfate, dopant, coating material, or packaging stock available for production or shipment.
  • Average daily material demand: Use MRP demand, production schedule, customer shipment plan, or average issue rate on the same kg basis.
  • Safety coverage multiplier: Use 1.0 for no derating or a higher multiplier to reserve stock for lead-time risk, quality holds, or demand variation.

How to use the result

  • Use it when inventory coverage in cathode active material and precursor manufacturing is being reviewed for stockout risk.
  • Lead time variability and supplier reliability are not in the formula. Adjust safety multiplier to compensate.

Common questions

  • What does the inventory coverage calculator give me? Estimate adjusted days of coverage for CAM, precursor, metal sulfate, lithium source, or dopant inventory using stock on hand, daily demand, and a safety multiplier. You get a protected days of supply you can defend before quoting, scheduling, or sign-off.
  • Which assumptions drive the protected days of supply? usable battery-material inventory on hand, average daily material demand, safety coverage multiplier usually move the protected days of supply most. Pull from measured cathode active material and precursor manufacturing runs, supplier data, and recent quotes rather than memory.
  • What do I do with this number? Use protected days to set the next reorder point or buffer level for cathode active material and precursor manufacturing.
  • What should I double-check before acting? Confirm daily usage is a real recent average, not a quarterly mean that hides a spike.
