01 / Calculate
Actual and dimensional weight are different inputs.
Dimensional weight reflects occupied space. The calculator compares it with actual weight and shows which value controls the reference billable weight.

Dimensional & Billable Weight Calculator
Calculate actual vs dimensional weight, expose the divisor, and see whether the same package is already approaching common handling thresholds.
Why this is differentThe result does not end at DIM weight. It connects weight, girth and handling signals back to shipment qualification.

Handling signals
No published handling-reference threshold matched these dimensions and weight.
Chargeable weight is a planning reference. Final billing weight can depend on carrier, service, route, packaging and contract terms.02 / Choose the divisor
The divisor belongs to a rate profile.
The supplied 2026 guides demonstrate why a single hard-coded divisor is unsafe: the daily/account-rate example uses 139 in³/lb, while the retail guide distinguishes domestic 166 from U.S. export 139.

Weight alone does not select a service.
After the calculation, run the real destination, cargo, battery status and dimensions through the active service matrix.

FAQ
Dimensional weight questions
What is dimensional weight?
Dimensional weight converts the space a package occupies into a reference weight. The divisor depends on the rate type or service, so it should not be treated as one universal constant.
What is billable or chargeable weight?
For a dimensional-weight calculation, billable weight is generally the greater of actual weight and dimensional weight. A specific service can still apply its own minimums, limits or handling rules.
Why does the calculator offer more than one divisor?
The supplied 2026 source guides show different divisor treatment by rate type. Exposing the divisor prevents a calculator from silently applying one carrier-specific assumption to every shipment.
Does this calculator qualify the shipment?
No. It calculates weight and surfaces physical warning signals. Use the Routing Checker to combine weight and dimensions with destination, cargo and active service rules.
