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.

Shipper pay (USD)

Amount paid by the shipper for the load in USD.

Carrier pay (USD)

Amount paid to the carrier for the load in USD; this is the percentage denominator.

Compute a freight broker's dollar spread and its percentage relative to carrier pay; this carrier-cost basis differs from gross margin on shipper revenue. 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]

Margin (USD)

Shipper pay minus carrier pay; a negative result is a loss.

Margin on carrier pay (%)

Dollar spread divided by carrier pay, expressed as a percentage.

• 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.

• Fuel Surcharge Percent Add-On Calculator

  Add a percentage-based fuel (or emission) surcharge from your carrier tariff to a base freight charge.

• Cost per Unit Shipped Allocation

  Allocate a shipment's supplied freight and fee total evenly across its sellable units; this does not weight allocation by mass, volume, or value.

• Returns Reverse Logistics Cost Percent

  Express reverse-logistics spend for returned goods as a percentage of net revenue and as cost per returned unit.
