As of mid-2026, the U.S. national average spot rate is about $3.01 per mile for dry vans, $3.42 for reefers and $3.64 for flatbeds, fuel surcharge included — DAT's July 2026 figures, after the strongest June-to-July contract jump on record. Strip out fuel and van spot linehaul averaged $2.39 per mile. August has cooled from that peak: by the week of August 9–15 vans averaged $2.93 all-in and flatbeds $3.54. Those are midpoints of a wide distribution — lane, equipment, timing and market balance move real quotes 50 cents or more in either direction — and rates a full dollar above July 2025, which is exactly why per-mile math is worth re-running before every quote.
What is the average freight rate per mile right now?
One number is never the market. A usable per-mile picture needs four numbers per trailer type — spot vs contract, linehaul vs all-in — because a "rate per mile" quoted without those qualifiers is ambiguous by about 20%. Here is the full DAT national-average grid for July 2026:
| Equipment (July 2026) | Spot, all-in | Spot linehaul | Contract, all-in | Contract linehaul | Avg fuel surcharge |
|---|---|---|---|---|---|
| Dry van | $3.01/mi | $2.39/mi | $3.01/mi | $2.39/mi | $0.62/mi |
| Reefer | $3.42/mi | $2.75/mi | $3.29/mi | $2.62/mi | $0.67/mi |
| Flatbed | $3.64/mi | $2.90/mi | $3.83/mi | $3.09/mi | $0.74/mi |
Three things stand out. Spot van matched contract van to the penny — the sign of a market that has tightened until the discount for one-off freight is gone. Reefer spot actually ran above reefer contract, which happens when produce season and tight refrigerated capacity collide. And year over year the move is dramatic: July spot linehaul was up 76 cents for van, 79 for reefer and 86 for flatbed versus July 2025. August pulled back — DAT's weekly averages for August 9–15 were $2.93 van, $3.38 reefer, $3.54 flatbed all-in, with its 35-day forecast easing another notch toward mid-September. Note also that indexes disagree: the same mid-August week, Truckstop's van average printed $2.62 while DAT's printed $2.93, because they sample different loads. Treat any single published average as a reference point, not a price.
How does the fuel surcharge work?
The surcharge is the mechanical part of the rate: most schedules take the EIA's weekly on-highway diesel average, subtract a peg price written into the contract, and divide by an assumed fuel economy. Diesel averaged $5.454/gallon the week ending August 17, 2026 — up almost 20 cents in a week — so a schedule pegged at $2.00 with a 6.5-mpg assumption pays ($5.454 − $2.00) ÷ 6.5 ≈ $0.53 per mile, right in line with the 62-cent van average DAT recorded in July. Geography moves it too: the same week diesel ran $5.24 on the Gulf Coast but $6.79 in California, which is part of why West Coast lanes carry fatter all-in rates. The practical rule: always ask whether a quote is linehaul or all-in, and which index, peg and mpg the surcharge schedule uses — a 2¢/gallon disagreement is noise, but a $0.80 peg difference is 12 cents a mile.
Why can't rates fall below about $2.30 a mile?
Because that's what the truck costs. ATRI's 2026 operational-costs report put the average marginal cost of trucking at a record $2.336 per mile for 2025 (up 3.4%), or $1.854 excluding fuel — with tolls (+13.2%), repair and maintenance (+8.6%), driver benefits (+6.6%) and tires (+6.4%) doing the pushing. Margins show how thin the cushion is: truckload and refrigerated fleets averaged under 1% operating margin, and flatbed carriers ran a −0.5% loss. When a spot rate prints below roughly $2.30–$2.40 all-in, carriers are hauling at or under cost, capacity exits, and rates snap back — the mechanism behind 2026's rebound.
Worked example: pricing a 1,000-mile van load
Chicago to Dallas-ish — call it 1,000 miles — at July 2026 national averages:
| Line | Math | Amount |
|---|---|---|
| Spot linehaul | 1,000 mi × $2.39 | $2,390 |
| Fuel surcharge | 1,000 mi × $0.62 | $620 |
| All-in to the shipper | 1,000 mi × $3.01 | $3,010 |
| Carrier's cost to run it | 1,000 mi × $2.336 | $2,336 |
| Margin before deadhead & broker share | $3,010 − $2,336 | $674 |
That $674 is the gross spread on the loaded miles — before the empty miles to reach the pickup, which is why carriers quote lanes, not distances. Run the same math at the mid-August weekly average ($2.93 all-in) and the spread thins to $594; at 2025's rates it mostly wasn't there at all. If your freight doesn't fill the trailer, the next question is whether you should be buying the whole truck in the first place — which is a pallet-count and density question before it's a rate question.
Does LTL have a rate per mile?
Not the way truckload does. LTL is priced per hundredweight (cwt) against freight class, lane and weight break, so the per-mile figure is something you back out afterward, not a tariff input. The 2026 contract average runs about $46.40/cwt, single pallets commonly price from about $120 up to the mid-$500s (one 2026 benchmark put the national average for a 500-lb class 70 pallet at $532, median $453), and LTL rates are up roughly 14% year over year on general rate increases plus the NMFC reclassification wave. Backed out to per-mile equivalents, one-pallet shipments range from about $0.42/mile leaving soft markets like Denver or El Paso to $2.12/mile out of Newark — short hauls always look expensive per mile because pickup, cross-dock and delivery costs don't shrink with distance. The lever you control is class: density decides most classes now, so run the four-step calculation before the carrier's dimensioner does it for you.
When does the whole truck get cheaper than LTL?
The crossover sits around 8–12 pallets or 10,000–15,000 lb. A worked 800-mile comparison from 2026 benchmarks: 9 pallets at 12,000 lb prices about $1,700 as LTL, while the full truckload at a $2.05 linehaul runs $1,640 — the whole trailer for less than the partial, plus one driver, no cross-docks and days off the transit time. Below the crossover LTL wins because you pay only for your share of the trailer; above it you're paying LTL handling on freight that already fills the nose of a van. If you're regularly tendering six-plus pallets, price both modes every time — and check how many pallets your freight actually is with the 53-foot trailer math, because "12 pallets" that double-stack is really six positions. The full input-by-input breakdown of what moves an LTL invoice is in what LTL freight shipping actually costs.
The per-mile number you should carry around in 2026: figure about $3 a mile all-in for a van, mid-$3s for reefer and flatbed, a cost floor near $2.34, and a fuel surcharge near 60–75 cents that moves weekly with the EIA print — then treat every published average as the starting bid, not the answer.
