Mexico to US Cross-Border Truckload Cost Per Unit Calculator
Trucking is the main advantage of nearshoring, but only if the cost per unit is understood. This calculator adds the cross-border items that a domestic rate leaves out and shows the freight cost per unit and as a share of cargo value.
Your numbers
Rate agreed with the carrier, including fuel surcharge.
Drop and hook or transfer at the border, if applicable.
Your results
Uses rates you enter. Actual cross-border pricing depends on carrier, lane, season, equipment and security requirements. Not a quote.
Freight cost per unit vs units per truckload
Sweeps Units per truckload from 500 to 10000, holding your other inputs fixed.
Real freight cost per lane from your ERP
Optional: see how freight actuals can feed standard cost.
Optional. The tool and every export work without this. No spam.
How to use it
Enter the lane distance and the carrier's rate per mile, then add border crossing or drayage, customs broker fees on both sides and expected detention. Add cargo value and the insurance rate, then the number of units per trailer. The tool outputs the cost of one load and the cost per unit. Use the chart to see the effect of better cube utilization.
- Use average detention, not best case.
- Quote against a full trailer, not a half-load.
- Add the cost of the return empty if it is not in the carrier rate.
Method
Linehaul is miles times rate per mile. Detention is hours times the hourly rate. Insurance is cargo value times the rate. The all-in load cost is the sum of linehaul, border fee, broker fees, detention and insurance. Dividing by units gives the freight cost per unit. Freight as a share of value shows how heavy the logistics burden is for the part, which matters most for low-value bulky goods.
Worked example
A 900 mile lane at 2.60 per mile is 2,340 dollars. Add 350 for border handling, 220 for brokers, 240 for four hours of detention and 150 for insurance on a 60,000 dollar load. The load costs 3,300 dollars. Spread over 4,000 units that is 0.825 dollars per unit, or 5.5 percent of cargo value.
Common mistakes
Teams compare a Mexican all-in truck rate with a Chinese port-to-port ocean rate and forget the inland legs, duties and inventory. Also common are underestimating border dwell, ignoring empty returns and not accounting for C-TPAT or similar security program requirements. Compare on a delivered-to-dock basis for both lanes.
Frequently Asked Questions
Does this include duty?
No. Customs duty and IVA are separate. Use the Mexico import tax calculator for goods entering Mexico, and check USMCA qualification for goods going to the US so that duty is not charged at all.
What is a realistic detention time?
It varies by crossing, season and inspection rate. Use your carrier's actual average over the last quarter rather than a target, since a few long waits dominate the average.
Should I include inventory in transit?
That is a separate cost, covered in the pipeline inventory calculator. Add it to freight when comparing lanes because ocean freight is slower and carries more inventory.
How do I improve cost per unit?
Raise units per truckload by redesigning packaging, consolidate loads, negotiate rates by volume and reduce detention with pre-cleared documents. The chart shows how steeply cost per unit falls as the trailer fills.
Netray can pull freight costs by lane from your ERP and show real cost per unit instead of a standard estimate.
