62 to 85% of freight forwarder and logistics revenue is spent on carrier rates. Truckload operating margins are hovering near 1%. The average cost to operate a truck hit $2.336 per mile in 2025 — the highest ATRI has ever recorded.
In a margin environment this compressed, the difference between a profitable logistics operation and an unprofitable one is often not revenue — it is cost visibility.
Most businesses know what they are spending on freight. Very few know which specific lanes, carrier relationships, and accessorial patterns are quietly destroying their margins while the rest of the network performs fine.
A supply chain data analyst who owns your lane profitability review is how you find the leaks before they compound into a P&L problem.
Where Margin Leakage Hides in Freight Operations
Margin leakage in freight is rarely a single large problem. It is a collection of smaller, invisible inefficiencies — each one manageable in isolation, but compounding into a meaningful shortfall when left unexamined across an entire network. Here is where the analysis consistently finds the most money.
Unprofitable Lanes Masked by Network Averages
Network-level freight metrics are averages — and averages hide the lanes that are dragging them down.
A business running 50 lanes might have 5 lanes performing significantly below breakeven. Those 5 lanes do not show up in the average cost per mile or the average margin per shipment. They show up in the quarterly P&L as an unexplained shortfall after everything else has been accounted for.
The revenue growth is not margin growth problem is real in freight. Over 80% of brokers reported spot rates rising year-over-year in H1 2026 — but 43% said margins were lower than the second half of 2025. Revenue up, margin down, and the gap between them is hiding somewhere in lane-level data that nobody is systematically reviewing.
Carrier Markup Drift
Carrier pricing is not static. It drifts — and it drifts in the carrier’s favor when shippers are not actively monitoring it.
A carrier who started at a negotiated rate 18 months ago may be running 12 to 15% above market on specific lanes today — not through a formal rate increase, but through the gradual accumulation of accessorials, fuel surcharge changes, and spot-rate exposure on lanes where contract coverage has lapsed.
Plugging cost leakage typically returns more than any rate card change a forwarder can defend. That is because the leakage is not in the rate — it is in the gap between the contracted rate and what is actually appearing on invoices.
Accessorial Proliferation
Accessorials are the fastest-growing cost category in freight — and the least visible in aggregate reporting. Liftgate. Residential delivery. Limited access. Driver detention. Redelivery.
Each accessorial charge is individually defensible. In aggregate, they represent a meaningful percentage of total freight spend — and they are almost never tracked at the lane or carrier level in standard freight reporting.
A business that monitors total freight spend without monitoring accessorial spend by carrier and lane is missing the category where markup drift most commonly concentrates.
What a Supply Chain Data Analyst Actually Does
Finding margin leaks requires more than a high-level spend review. It requires someone who works through the shipment-level data systematically — building lane models, benchmarking rates, auditing invoices, and translating findings into specific recovery actions. Here is what each function involves.
Lane-Level Profitability Analysis
A data analyst pulls shipment-level data from your TMS and freight payment systems and builds a lane-level profitability model — cost per mile, cost per shipment, and total spend by lane against revenue or value generated on that lane.
This model surfaces the specific lanes where freight cost exceeds the value threshold — the ones that look fine in aggregate but are actually subsidized by the rest of the network. Most businesses discover that 10 to 20% of their lanes are running below acceptable margin when they look at the data at lane level for the first time.
Carrier Rate Benchmarking
A data analyst benchmarks your contracted carrier rates against current market rates on equivalent lanes — using DAT, Truckstop, or your preferred market data source — and flags the carriers and lanes where your rates have drifted significantly above market.
This benchmarking is not a once-a-year RFP exercise. It is a quarterly monitoring function that catches drift before it compounds. A carrier running 8% above market on a single lane may represent $30,000 to $80,000 in excess spend annually on a high-volume corridor — spend that a benchmarking review catches and a renegotiation recovers.
Accessorial Audit
A data analyst reviews your freight invoices at the line-item level — categorizing every accessorial charge by type, carrier, and lane — and produces a report showing which carriers and which lanes are generating the highest accessorial exposure.
This audit frequently surfaces two categories of finding: legitimate accessorials that indicate an operational problem — consistent detention charges on a specific lane suggest a dock scheduling issue — and potentially unjustified accessorials that require carrier reconciliation or dispute.
Invoice Reconciliation and Dispute Identification
A data analyst compares carrier invoices against contracted rates and shipment records — flagging discrepancies between what was agreed and what was charged. Invoice errors in freight billing are more common than most shippers realize — and a systematic reconciliation process catches them before payment rather than after.
Reporting and Savings Recommendations
A data analyst compiles findings into a structured report — identifying the top margin leak sources, quantifying the recovery opportunity on each, and recommending specific actions: lane renegotiations, carrier consolidation decisions, accessorial dispute filings, or operational changes that address root causes.
This report is what converts data analysis from a retrospective exercise into a forward-looking cost management tool.
