Freight Weight Calculator

Calculate freight weight from dimensions and actual weight

Use this calculator when a quote asks for freight weight, shipment weight, or chargeable weight. Enter the package dimensions, actual weight, number of packages, and divisor.

This is an estimate for planning and supplier communication. Your carrier, forwarder, marketplace, destination country, contract, and service level may use a different divisor, rounding rule, minimum weight, or surcharge.

What freight weight usually means

Freight weight often means the weight used for pricing, not only the number shown on a scale. For air freight and courier shipments, the billable freight weight is commonly the higher of actual weight and dimensional weight.

For sea freight, freight cost may depend more on CBM, container space, or minimum charge rules. That is why the same carton can need different estimates for different shipping methods.

Real-world use case

A supplier says the goods are 80 kg, but the cartons are large. Before comparing quotes from two forwarders, calculate the freight weight using their divisor. If the dimensional weight is 115 kg, your cost estimate should be based closer to 115 kg than 80 kg.

Common mistakes

• Assuming freight weight always equals actual scale weight.
• Comparing quotes without confirming whether the divisor is 5000, 6000, 4000, 139, or another value.
• Entering total shipment dimensions instead of per-package dimensions when cartons are separate.
• Ignoring pallet dimensions when the shipment will be palletized.
• Comparing air freight and sea freight with the same weight logic.

When this tool is not enough

This tool does not replace a freight quote. A real quote may include pickup, export handling, customs clearance, security fee, fuel surcharge, remote delivery, taxes, palletization, and minimum billable weight.

FAQ

Is freight weight the same as chargeable weight?

In many quotes, freight weight refers to the chargeable or billable weight. Confirm the wording with your carrier or forwarder.

Which shipping method uses dimensional freight weight?

Courier, express, and many air freight services commonly use dimensional or volumetric weight. Sea freight is often quoted by CBM or container space.

Should I enter total shipment weight or per package weight?

Enter per-package dimensions and actual weight, then set the number of packages. This avoids multiplying the dimensions incorrectly.
