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.

Delivery times

Observed delivery durations in minutes.

Percentile

Percentile level to promise, 0-100.

Compute the p-th percentile (linear interpolation between closest ranks) of observed door-to-door delivery minutes to set a promised time slot that the fleet can keep. 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]

Promised slot (min)

Promised slot length in minutes at the requested percentile.

Sample count

Number of observations used.

Slowest (min)

Slowest observed delivery in minutes.

• 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.

• 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.

• Demurrage Free Days Port Checker

  Count container demurrage days using inclusive free time that starts on the discharge day, so the last free day is discharge date plus free days minus one and chargeable days run after it through pickup.

• Putaway Time Per Pallet Estimate

  Estimate putaway productivity as minutes per pallet moved and the equivalent pallets per hour.
