Reshoring & Tariff Strategy worked example

Freight Lead Time Buffer at 7.2% setup, handling, and delay allowance: a worked example

Suppose setup, handling, and delay allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate freight lead time buffer for reshoring and tariff strategy using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Freight lead time buffer workload: 120 units (held at the documented default)
  • Freight lead time buffer completion rate: 12 units / min (held at the documented default)
  • Setup, handling, and delay allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base freight lead time buffer time = freight lead time buffer workload รท freight lead time buffer completion rate.
  • Required freight lead time buffer time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base freight lead time buffer time works out to 10 hr at these inputs.
  • Freight lead time buffer allowance applied works out to 7.2 % at these inputs.
  • Freight lead time buffer completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It divides workload by completion rate to get base processing time, then inflates it by a setup-and-delay allowance to give required buffer time. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required freight lead time buffer time: 10.72 hr (headline result)
  • Base freight lead time buffer time: 10 hr
  • Freight lead time buffer allowance applied: 7.2 %
  • Freight lead time buffer completion rate: 12 pieces / min

Run it with your numbers
