Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Hours at facility (h)

Hours the driver waited at the facility.

Free time (h)

Contractual free hours allowed before detention starts; zero means billing starts immediately.

Check driver wait hours at a facility against the free time allowance to see whether detention billing triggers. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Detention triggered

Whether detention billing is triggered.

Billable hours (h)

Billable detention hours beyond the free time.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Trailer Dwell Time Hours Checker

  Check trailer dwell hours against the facility free time allowance and report excess hours.

• Order to Door Response Time

  Measure elapsed hours between order placement and doorstep delivery and check the result against a delivery-promise target in hours.

• Additional Handling Fee Trigger Checker

  Check a rectangular parcel against configurable longest-side, second-longest-side, actual-weight, and length-plus-girth thresholds; packaging and service-specific rules are outside this numeric screen.
