Transparent methodology

Formula & assumptions.

A planning allocation calculator for shared shipment costs across multiple SKUs.

Calculation formula

Allocation base = units, total weight, total volume or product value

Shareᵢ = baseᵢ ÷ Σ base

Allocated costᵢ = shipment cost × shareᵢ

Total allocated shared costᵢ = total shared cost × shareᵢ

Freight cost per unitᵢ = allocated freightᵢ ÷ unitsᵢ

Shipping & import cost per unitᵢ = total allocated shared costᵢ ÷ unitsᵢ

Delivered cost per unitᵢ = unit product costᵢ + shared import cost per unitᵢ

Choosing a method

  • By Units suits products with a similar freight footprint.
  • By Weight suits costs driven mainly by shipment weight; By Volume suits space-driven freight.
  • By Product Value can suit value-based accounting or insurance allocation.
  • The best allocation method depends on accounting policy, freight billing basis, management reporting purpose, customs treatment and business rules.
  • This tool provides planning allocation only. It is not tax advice, customs advice or accounting certification.

Frequently asked questions

Clear answers before you allocate.

Understand what this multi-SKU cost allocation can guide — and what remains a business decision.

Is this a shipping cost per unit calculator?⌄

Yes. It calculates freight cost per unit and the broader shipping and import cost per unit after allocating shared shipment costs.

Which allocation method should I use?⌄

Choose a method that matches your accounting policy, freight structure and intended business use. The calculator does not determine that policy.

Does currency conversion happen automatically?⌄

No. Currency is a display label only. Enter all costs in one chosen currency.

Can I allocate costs across more than two SKUs?⌄

Yes. Add up to 10 SKU rows and the allocation updates instantly.

Why is a SKU cost per unit unavailable?⌄

A SKU with zero units cannot have a per-unit cost, even when its allocation share is valid under another method.

Does this replace the Landed Cost Calculator?⌄

No. Landed Cost estimates one shipment total. This tool allocates entered shared shipment costs across multiple SKUs.
