How do you calculate freight cost per unit?

Divide total freight cost by units shipped, then multiply by any normalization factor. $4,200 of freight on 1,500 units with a factor of 1 gives 4,200 ÷ 1,500 × 1 = $2.80 per unit.

What is the normalization factor for?

It rescales the result to a comparable basis — for example converting per-case to per-piece, or adjusting to a standard pack. Left at 1, the output is a straight cost-per-unit; the example uses 1, so $2.80 is the raw per-unit freight.

What is a good freight cost per unit?

There is no universal target; it depends on unit value and mode. As a rule of thumb, freight running under 5-10% of unit cost is comfortable, while $2.80 on a low-value item may signal a mode or consolidation problem worth fixing.

Should freight cost per unit be in landed cost?

Yes. Landed cost is ex-works price plus freight, duty, insurance, and handling per unit. Adding the $2.80 freight figure to the supplier's unit price gives a far truer basis for sourcing decisions.

How do I lower freight cost per unit?

Ship more units per load (improve container or trailer utilization), consolidate shipments, negotiate lane rates, or shift to a cheaper mode when transit time allows. Doubling units on the same $4,200 load would halve the per-unit cost.

Does this include accessorials and fuel surcharges?

Only if you include them in the total freight cost input. For a true per-unit figure, put the all-in freight bill — base rate, fuel, and accessorials — into the total, not just the linehaul.

Supply Chain & Procurement calculator

Freight Cost per Unit Calculator

Freight cost per unit spreads a shipment's total transportation cost across the units it carried, giving procurement and logistics teams the single number they need to fold freight into landed cost and pricing. It is the metric that reveals whether an inbound lane, a mode choice, or a load configuration is actually economical once you account for how many sellable units rode along. Cost accountants use it to allocate freight into COGS; sourcing teams use it to compare suppliers on true delivered cost rather than ex-works price. It matters because a low unit price from a distant supplier can quietly evaporate once per-unit freight is layered on top.

What this calculator does

Calculate freight cost per unit for Supply Chain & Procurement from total freight spend and units shipped.
Use it to load freight into landed cost and compare lanes in Supply Chain & Procurement.
Computes the freight cost carried by each unit by dividing total freight cost by units shipped, then applying an optional normalization factor.

Formula used

Freight cost per unit = total freight cost ÷ units shipped × normalization factor

Inputs explained

Total freight cost for shipment:
Units shipped in shipment:
Unit normalization factor:

How to use the result

Use it when comparing inbound lanes or suppliers on landed cost, allocating freight into product costing, or evaluating whether a mode or consolidation change pays off.
It assumes every unit shares freight equally; for mixed-SKU loads of different sizes or weights, an even split can misallocate cost toward small units and understate it for bulky ones.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
Sourcing currencies as of 2026-07-02 (Federal Reserve H.10): 6.7886 CNY and 17.4524 MXN per USD. Landed-cost comparisons move with these daily rates.
U.S. iron and steel imports ran $2.1B in May 2026 (Census International Trade). The U.S. ran a trade deficit of $0.4B in the category that month. Import volumes are the pressure gauge behind tariff and reshoring decisions.
