Tooling, Fixtures, Dies & Mold Economics calculator

Tool Crib Inventory Calculator

Estimate tool crib inventory for tooling, fixtures, dies and mold economics using production-ready inputs so teams can plan replenishment and safety stock using actual usage and lead time. On-hand divided by daily usage, then divided by safety multiplier, gives a protected days of supply.

What this calculator does

  • Estimate tool crib inventory for tooling, fixtures, dies and mold economics using production-ready inputs so teams can plan replenishment and safety stock using actual usage and lead time.
  • Use it when tool crib inventory in tooling, fixtures, dies and mold economics is being sized for a buffer or safety stock review.
  • Turns tool crib inventory daily usage, tool crib inventory lead time, tool crib inventory safety stock into a protected days of supply for tool crib inventory in tooling, fixtures, dies and mold economics.

Formula used

  • Tool crib inventory cycle stock = tool crib inventory daily usage × tool crib inventory lead time
  • Required tool crib inventory = cycle stock + tool crib inventory safety stock

Inputs explained

  • Tool crib inventory daily usage: Use recent consumption, demand history, service usage, production schedule, or MRP issue rate.
  • Tool crib inventory lead time: Enter supplier, internal replenishment, repair, transit, or planning lead time.
  • Tool crib inventory safety stock: Add buffer for demand variation, supplier risk, quality holds, downtime, or service-level requirements.

How to use the result
