How Truckload Rates Are Built: Linehaul, Fuel and Accessorials

A buyer compares two truckload bids for the same Chicago to Atlanta lane, picks the one that is $140 cheaper, and three months later finds the lane costing more than the losing bid would have. The winning carrier quoted a low linehaul, used a lower fuel peg, and bills a stop-off and two hours of detention on most loads. Nothing on the invoices was hidden; the bids were simply never compared layer by layer.

Every truckload price is built from the same three layers: a linehaul that recovers the carrier's cost of the truck, driver and empty miles; a fuel line that moves with a diesel index; and accessorials that only apply when something specific happens. Pricing and auditing each layer on its own makes bids comparable, keeps invoices predictable and shows where a lane's cost is really coming from.

• What you will find here: how carriers build linehaul from cost per mile, the lane factors that push it up or down, how US and Indian fuel adjustments are calculated, and which accessorials need evidence.
• Worked material: a full rate build for one US and one Indian lane, the formulas behind it, an invoice that drifted from its confirmation, and an audit checklist for buyers.

Three layers on every truckload invoice and why buyers split them

Linehaul, fuel and accessorials should be agreed, stored and audited separately even when the carrier quotes one all-in number. Each layer has a different driver, a different source document and a different person who can change it, so a single total hides which one moved.

Linehaul is fixed for the contract period or for one spot load. Fuel changes with a published index, usually weekly in the US and daily at the pump in India. Accessorials are conditional: they are owed only when a stated trigger occurs, such as a second stop or a wait beyond the free period. Mixing them makes a fuel spike look like a rate increase and makes a recurring detention problem look like normal pricing.

Linehaul starts from carrier cost per mile, not from a posted rate

A sustainable linehaul covers the carrier's non-fuel cost for every mile the truck drives, loaded or empty, plus a margin that depends on how easy it is to reload at destination. Market boards show what loads cleared at last week, but a carrier's floor is its own cost, and contracts priced below that floor tend to fail through tender rejections rather than through invoices.

The American Transportation Research Institute's 2026 operational cost report puts the 2025 industry average at $2.336 per mile, up 3.4% from $2.260 in 2024, and $1.854 per mile excluding fuel. The same release reports truckload operating margins below 1%. Those are averages across fleets, not a lane price, but they show the order of magnitude a buyer is negotiating against.

Truckload linehaul pricing for a US dry-van lane starts from carrier cost per mile; ATRI's 2026 operational cost report puts the 2025 industry average at $2.336 per mile, or $1.854 excluding fuel, so a contract linehaul well below non-fuel cost on a long lane deserves a capacity-risk review.

The conversion from cost per mile to rate per loaded mile is where empty miles enter. A truck that drives 716 loaded miles and 90 empty miles to reach its next load spends 806 miles of cost to earn 716 miles of revenue. The formulas below show the build, with the fuel layer kept out of linehaul because it is billed separately.

Linehaul rate per loaded mile
  LH = C_nf x (M_loaded + M_empty) / M_loaded / (1 - m)

  C_nf     = carrier non-fuel cost per mile (USD)
  M_loaded = loaded miles on the lane
  M_empty  = empty miles to reposition for the next load
  m        = target margin as a share of linehaul revenue

US fuel surcharge per loaded mile
  FSC = max(0, (P_index - P_peg) / MPG)

  P_index  = EIA weekly on-highway diesel price for the agreed region and week (USD per gallon)
  P_peg    = base price already recovered inside linehaul (USD per gallon)
  MPG      = agreed miles per gallon

India diesel escalation per trip
  ESC = (D_km / KMPL) x (P_dispatch - P_base)

  D_km       = trip distance in kilometres
  KMPL       = agreed kilometres per litre
  P_dispatch = retail diesel price on the agreed date and city (INR per litre)
  P_base     = diesel price built into the trip rate (INR per litre)

Lane factors that push linehaul above or below cost

Two lanes of equal length can price very differently because the carrier's real cost includes what happens after delivery. Lane factors are the reasons a carrier adds or removes margin, and naming them in the bid lets a buyer influence the ones it controls.

• Destination reload odds: a delivery into a market with many outbound loads lets the carrier reload quickly, so the headhaul rate falls; a delivery into a consuming region with few outbound loads carries the empty return.
• Length of haul: short hauls under a day carry fixed time at both docks, so rate per mile rises sharply; many carriers set a minimum charge per load rather than per mile.
• Dwell at the shipper and receiver: sites that keep trucks four hours price higher even when detention is billed, because the lost driving hours cannot be resold.
• Equipment and handling: refrigerated, flatbed with tarping, team service and hazardous loads each add cost and qualification requirements beyond a dry van.
• Tender lead time and volume certainty: loads tendered a day ahead on a predictable weekly pattern price below loads tendered same day with uncertain volume.
• Appointment flexibility: wide pickup windows let carriers chain loads; a fixed 06:00 appointment may force an empty move or overnight wait.

Calculating and checking the fuel layer

The fuel line is the most mechanical part of the rate and therefore the easiest to audit completely. Recompute it on every invoice from the contract's index, region, week, peg and miles per gallon; any difference is either a data error or a contract drift.

In the US, most contracts use the Energy Information Administration's weekly retail on-highway diesel price, published for the national average and for regional series such as the East Coast, Midwest, Gulf Coast, Rocky Mountain and West Coast. EIA reported a US average of $6.127 per gallon for the week of 9 November 2026. With a $1.25 peg and 6.0 miles per gallon, the surcharge is ($6.127 - $1.25) / 6.0, or $0.813 per loaded mile.

Fuel surcharge audits on US truckload invoices recompute the charge from the EIA weekly on-highway diesel price named in the contract, minus the peg, divided by agreed miles per gallon; at $6.127 per gallon, a $1.25 peg and 6.0 mpg, the surcharge is $0.813 per loaded mile.

The peg is not a discount. At $1.25 a gallon and 6.0 miles per gallon, $0.208 per mile of fuel cost already sits inside linehaul, so a bid with a high peg and a low linehaul is not cheaper than one with a low peg and a higher linehaul. Our deeper page on fuel surcharge index tables and weekly bracket updates covers table automation; here the point is only how fuel fits into the full rate.

• Index week: the contract should say whether the pickup week, tender week or delivery week applies; a mismatch on a week of rising prices shifts cost silently.
• India daily prices: public sector oil marketing companies have revised retail petrol and diesel prices daily since 16 June 2017, with each price applying from 6 AM to 6 AM, so escalation clauses must name a city and a date.
• India calculation base: escalation is usually computed on trip litres, distance divided by agreed kilometres per litre, rather than per kilometre; agree the litres once per lane.
• Thresholds and bands: some Indian contracts adjust only when diesel moves more than an agreed amount per litre, which avoids small daily changes on every bill.

Stops, waiting and loading help in the accessorial layer

An accessorial is only payable when its trigger happened and the evidence shows it. The contract should list each charge with its trigger, free allowance, rate and required proof, and the audit should reject any accessorial line that does not match one of them.

Lumper charges have a statutory anchor in the US. Under 49 U.S.C. 14103(a), a shipper or receiver that requires the driver to be helped with loading or unloading must provide the help or pay the carrier's cost of securing it, and section 14103(b) makes coercing a carrier into paying for that help unlawful.

Lumper charges on US truckload invoices follow 49 U.S.C. 14103(a): a shipper or receiver that requires help loading or unloading must provide it or pay the carrier's cost, so freight audit should match each lumper line to a dated receipt naming the facility on the rate confirmation.

Detention evidence and cancellation charges each have their own detailed guides. See building the detention timeline before approving a claim and our explainer on TONU, layover and redelivery fees; this article treats them only as one layer of the rate.

Building one lane rate in dollars and one in rupees

A full build shows how much of the invoice is linehaul and how much depends on fuel and site behaviour. The two lanes below use illustrative figures; the US fuel index is EIA's published average for the week of 9 November 2026, and every other number is an assumption for the example.

Linehaul is 60% of the US invoice and 90% of the Indian one before tax. On the US lane, fuel adds another 22%, which is why a fuel schedule difference between bids can outweigh a linehaul difference. On both lanes, the site-driven lines, stops, waiting and labour, add between 9% and 18% and are the part a shipper can reduce without negotiating with anyone.

Where tax, tolls and dispute windows sit outside the rate

Some items on a truckload bill are not part of the carrier's price at all: they are taxes, pass-through costs or legal deadlines. Keep them out of rate comparisons and handle them with their own rules.

In India, a goods transport agency's freight attracts GST either at 5% without input tax credit, often paid by the recipient under reverse charge, or at 18% with credit when the GTA opts to pay tax itself. Notification 15/2025-Central Tax (Rate) raised the central share of the with-credit option from 6% to 9% from 22 September 2025. Our page on GST on goods transport agency services covers the declarations and recipient categories.

Indian truckload freight billed by a goods transport agency carries GST at 5% without input credit, often under reverse charge, or 18% with credit after Notification 15/2025-Central Tax (Rate) raised the central share to 9% from 22 September 2025; freight audit must record which option each transporter declared.

• Tolls in India: agree whether FASTag toll debits are inside the trip rate or reimbursed at actuals; reimbursed tolls need the issuer statement, not a transporter estimate.
• US rate disclosure: under 49 U.S.C. 13710(a)(1), a motor carrier must give a shipper, on request, a written or electronic copy of the rate, classification, rules and practices applied to its shipment.
• US billing disputes: 49 U.S.C. 13710(a)(3) sets 180-day windows for a carrier to rebill additional charges and for a shipper to contest a bill, so audits should finish well inside six months.

An invoice that drifted from its rate confirmation

Most truckload overbilling is not one large error but several small ones that pass a total-level tolerance. The trace below shows a single load on the US lane from the worked example and how a line-level check would have caught it.

1. Monday 14:10: Rate confirmation RC-55821 issued: linehaul $1,611.00, fuel at EIA US average for the pickup week, one stop-off at $100, detention at $75 per hour after two free hours.
2. Wednesday 06:55 to 11:05: Truck checks in at the receiver for a 07:00 appointment and leaves at 11:05. Gate records show 4 hours 10 minutes on site; after two free hours, the contract's whole-hour rule makes two hours billable.
3. Friday 09:20: EDI 210 invoice INV-88214 arrives at $2,877.68: fuel computed on the tender-week index, EIA's $6.292 for the prior week, giving $601.68, the stop-off billed twice, and detention billed as three hours.
4. Friday 15:30: Freight settlement run FS-1107 auto-approves the invoice because the total is within the 10% tolerance configured for the carrier. Overpayment: $194.57, or 7.3% of the correct $2,683.11.
5. Following month: A lane review finds the same pattern on 41 loads. The tolerance is moved from invoice total to each line, and fuel is recomputed by the TMS rather than accepted from the carrier.

What the TMS should compute and what the freight buyer judges

Every number in a truckload rate that comes from a formula or a schedule should be computed by the system, not keyed in from the carrier's invoice. Judgement stays with people where the question is who caused a charge or whether a lane price is still right for the market.
