Long Lead Item Exposure Calculator

Use this calculator to estimate cost exposure tied to long lead items in machinery projects. It helps procurement and project teams compare expedite cost, alternate sourcing, inventory buys, and schedule risk.

What this calculator does

  • Estimate exposure from long lead purchased items using item count, extended cost per item, schedule exposure share, and fixed expediting cost.
  • Use it when reviewing motors, drives, PLCs, gearboxes, castings, fabricated frames, panels, or specialty components that can hold up a build.
  • The result estimates cost exposure tied to long lead purchased items.

Formula used

  • Variable long lead item exposure = long lead item count × extended cost per long lead item × schedule exposure share
  • Total long lead item exposure = variable long lead item exposure + fixed expediting and substitution cost

Inputs explained

  • Long lead item count: Count critical motors, drives, PLCs, actuators, sensors, panels, gearboxes, castings, fabricated frames, or specialty parts.
  • Extended cost per long lead item: Use the purchased cost, committed PO value, or replacement cost per critical item.
  • Schedule exposure share: Estimate the share of items likely to affect shipment, cash milestone, or build slot timing.
  • Fixed expediting and substitution cost: Include premium freight, engineering substitutions, supplier management, requalification, and schedule recovery actions.

How to use the result

  • Use it to decide on expedite spending, alternate components, early buys, or schedule contingency.
  • It depends on supplier commitments, acceptable substitutions, inventory policy, and customer schedule flexibility.

Common questions

  • What is the long lead item exposure calculator for? It estimates financial exposure from long lead parts on machinery projects.
  • What information should I enter? Use long lead item count, extended item cost, schedule exposure share, and expediting or substitution cost.
  • What does the result tell me? The result helps decide whether to expedite, source alternates, or add schedule contingency.
  • When is the result only an estimate? It is only an estimate when supplier dates, substitutions, project priorities, or inventory strategy change.
