Freight Cost per Unit Calculator
Convert a shipment’s total freight cost into cost per unit (and optional cost per case/pallet). Built for B2B quoting, landed cost modeling, margin analysis, and scenario planning.
Inputs
USDOptional packaging units
If you ship in cases and pallets, add packaging counts to compute cost per case and cost per pallet. Leave blank if not applicable.

What this calculator is
The Freight Cost per Unit Calculator converts a shipment-level freight cost into unitized costs you can use for pricing, landed cost modeling, and margin analysis. It helps teams answer: “What does freight add to each unit, case, or pallet?”
How it works
This calculator uses straightforward allocation:
- All-in freight used = total freight × (1 + buffer %)
- Cost per unit = all-in freight ÷ total units
- If you provide packaging units, the calculator derives:
- Cases = total units ÷ units per case
- Cost per case = all-in freight ÷ cases
- If you provide pallets in shipment, then cost per pallet = all-in freight ÷ pallets.
- If you don’t know pallet count but provide cases per pallet, we can estimate pallets using derived cases.
Rounding can be applied to per-unit results depending on your workflow. For conservative quoting, rounding up can reduce under-recovery risk. For site-wide conventions, see Methodology.
Input definitions
- Total freight cost: the shipment-level shipping cost you want to allocate (carrier invoice or estimate).
- Total units shipped: count of sellable items in the shipment.
- Risk buffer (%): optional increase to freight to account for uncertainty (accessorials, fuel variability, reweigh).
- Units per case: optional conversion factor if your shipment is packaged in cases.
- Cases per pallet: optional conversion factor if cases are stacked onto pallets.
- Pallets in shipment: if known, this provides the most direct cost per pallet calculation.
- Rounding approach: choose whether to round per-unit outputs (none/up/down).
Output definitions
- Freight cost per unit: freight allocated to each item.
- Cost per case: freight allocated to each case (only shown when units per case yields valid cases).
- Cost per pallet: freight allocated to each pallet (shown when pallet count is provided or can be derived).
- Derived counts: estimated cases/pallets based on optional inputs (for transparency).
Common B2B use cases
- Landed cost modeling: add freight per unit into COGS or pricing decisions.
- Quote support: translate lane-level freight into unit economics during quoting.
- Margin analysis: understand how freight changes contribution margin by SKU or case pack.
- Procurement comparisons: compare suppliers using all-in delivered cost rather than product cost alone.
Limitations and assumptions
- Allocation assumption: this tool allocates freight evenly across units. Some workflows allocate by cube, weight, or value.
- Packaging conversions: derived cases/pallets assume clean divisibility; real shipments may include partial cases/pallets.
- Buffer is optional: it is not a carrier surcharge; it’s a planning tool for uncertainty management.
For additional allocation approaches (e.g., weight-based allocation), you can model scenarios by adjusting unit counts or splitting freight across item groups.
Disclaimer
Packlyt tools provide planning estimates only. Validate allocation rules with your finance and operations teams, and confirm final freight charges via carrier invoices and contract terms.

FAQ
Should I allocate freight evenly across units?
Even allocation is common for quick planning, but some businesses allocate by weight, cube, or value. Use the method that matches your pricing and accounting approach.
What does the risk buffer do?
The buffer increases freight cost used in the calculation to account for uncertainty—such as accessorials, fuel variability, or invoice adjustments. It’s optional and should be based on your historical variance.
Why are cost per case/pallet blank sometimes?
Those outputs require valid packaging conversions (units per case, cases per pallet, or pallet count). If inputs don’t allow a clean conversion, the calculator will leave those results blank rather than guess.
