How do I calculate freight cost per unit accurately?

Freight cost per unit divides the total lane cost, including base rate, fuel surcharge, and accessorials, by the units or cases actually shipped on the load. The Freight Cost per Unit calculator makes this exact, and pairing it with Truckload Utilization matters because the same rate spread over a full trailer costs far less per unit than over a half-empty one. Underloaded lanes are usually the biggest hidden cost.

When is LTL cheaper than full truckload?

LTL wins when your shipment fills only a fraction of a trailer, since you pay for the space and weight you use rather than a full truck. As pallet count and weight climb, LTL class rates and handling surcharges eventually exceed a full truckload rate. The LTL vs FTL Cost Comparison calculator finds that breakeven, and Shipment Consolidation Savings shows when combining several LTL loads into one FTL beats shipping them separately.

How much does a fuel surcharge really add to my freight cost?

Fuel surcharges are a percentage or per-mile add-on tied to a diesel index, so they scale with distance and rise fast on long lanes. The Fuel Surcharge Impact calculator applies the current surcharge to your base linehaul so you see the true delivered cost, not the quoted rate. On long-haul lanes the surcharge can add double-digit percentages, which is why it belongs in every lane cost and carrier comparison.

How do I control detention and demurrage charges?

Detention accrues when a driver waits beyond free time at your dock, and demurrage accrues when containers sit at the port or ramp too long, both billed by the hour or day. The Truck Detention Cost and Demurrage Exposure calculators quantify what slow loading or delayed pickups cost, so you can justify faster dock turns or more free-time negotiation. These accessorials often rival the base freight rate on problem lanes.

What truckload or container utilization should I target?

Aim to fill the trailer or container to whichever limit you hit first, weight or cube, since you pay for the whole unit regardless. The Truckload Utilization and Container Utilization calculators show how much of each you actually used, and low utilization is the clearest signal to consolidate. Cube-out on light freight and weight-out on dense freight each waste capacity, so knowing which constraint binds guides how you build loads.

How much can freight audit and consolidation save?

Freight bills contain errors, from wrong classes to duplicate accessorials, and a formal audit typically recovers a few percent of spend. The Freight Audit Savings calculator estimates that recovery, while Shipment Consolidation Savings and Cross-Dock Savings quantify network-level gains from combining loads and bypassing storage. Lane Cost Variance flags lanes drifting above benchmark so you know where to renegotiate or reroute first.

Transportation, Freight & Distribution calculators

This category covers 37 calculators for freight cost, carrier decisions, and distribution network planning. It is built for transportation managers, logistics analysts, and shippers who need to cost lanes, size trailer and container fill, compare LTL against full truckload, and control accessorials like detention, demurrage, and fuel surcharges.

Best calculators in this category

Freight Cost per Unit: Allocate linehaul, fuel surcharge, accessorials, and fixed shipment cost across units, cases, or pallets to estimate freight cost per shipped unit.
Fuel Surcharge Impact: Compare freight cost with and without the fuel surcharge to see the surcharge dollars and percent impact on a lane, shipment, or monthly freight plan.
Delivery Route Cost: Estimate the total cost of a delivery route from route miles, cost per mile, billable route share, and fixed stop, dock, or dispatch charges.
Truckload Utilization: Measure how much trailer weight, pallet positions, or cube was used versus available truckload capacity and show the gap to the utilization target.
LTL vs FTL Cost Comparison: Build a side-by-side planning cost for LTL or truckload moves by combining shipment count, rate per shipment, chargeable share, and fixed accessorials.
Parcel Shipping Cost: Estimate parcel shipping spend from package count, parcel rate, billable share, and fixed pickup, residential, delivery-area, or oversize fees.
Distribution Center Handling Cost: Estimate warehouse handling cost from cases, pallets, or orders handled, handling rate, allocated share, and fixed dock or labor charges.
Delivery Route Productivity: Estimate daily successful deliveries from stops per route, available routes, dispatch uptime, and first-attempt delivery success.
Carrier Rate Acceptance: Track how often carrier quotes or tenders meet the target rate threshold so procurement can spot lane pricing drift.
Truck Detention Cost: Estimate detention charges from chargeable detention hours, hourly detention rate, billable share, and fixed admin or appointment fees.
Demurrage Exposure: Estimate port, rail, or container demurrage exposure from chargeable days, daily rate, risk share, and fixed broker or drayage charges.
Freight Audit Savings: Estimate recoverable freight audit dollars from invoice count, average overcharge, audit capture rate, and fixed recovery costs.
