Truck shipping rates are determined primarily by the distance of the lane, the weight and density of the freight, the freight class assigned to the commodity, the type of service used (LTL, partial, or full truckload), the current fuel surcharge, and any accessorial charges that apply at pickup or delivery. Market conditions, lane balance, and carrier capacity then move the final number up or down on any given day. In other words, no single factor sets the price—a truck shipping rate is built from a stack of variables, and the fastest way to see your exact number is to pull an instant online quote rather than wait on a phone call. ExFreight, a digital freight forwarder operating since 2009, returns live truck freight shipping rates from 50+ vetted carriers so you can compare, book in two clicks, and track every shipment from one dashboard.
What factors determine truck shipping rates?
Truck shipping rates are the sum of several measurable inputs. Understanding each one tells you why two shipments of the same weight can cost very different amounts and where you can shave cost out of a quote.
- Distance and lane: Longer hauls cost more, but the specific lane matters as much as the mileage. A lane with plenty of return freight (good “lane balance”) prices lower than a lane where trucks deadhead back empty.
- Weight and density: Heavier freight costs more, but carriers care just as much about how much space the freight occupies. Light, bulky cargo that fills a trailer without weighing much is priced on the room it consumes, not just the scale weight.
- Freight class: For less-than-truckload shipments, every commodity gets an NMFC freight class from 50 to 500 based on density, stowability, handling, and liability. Lower classes cost less per hundred pounds.
- Service type: LTL, partial truckload, and full truckload use different pricing models entirely, and the cheapest option depends on how many pallets you ship.
- Fuel surcharge: A percentage adjustment tied to national diesel prices that floats on top of the base linehaul rate.
- Accessorial charges: Extra services such as liftgate, residential delivery, inside delivery, or limited-access locations add fixed fees on top of the rate.
- Capacity and seasonality: When trucks are scarce—produce season, holiday peaks, weather events—rates climb. When capacity is loose, they soften.
How are LTL freight rates calculated?
LTL freight rates are calculated from the freight class, the billable weight, the origin and destination ZIP codes, the carrier’s base rate tariff, and the discount negotiated for that lane, then a fuel surcharge and any accessorials are added. Less-than-truckload shipping is for freight that occupies 1 to 6 pallets and does not need a full trailer, so you pay only for the portion of the truck you use while the carrier sells the remaining space to other shippers. Because pricing hinges on freight class and dimensions, an accurate quote depends on giving correct pallet weights and measurements up front. ExFreight’s LTL freight shipping uses a density-based engine that calculates the rate from your real dimensions, so you never have to guess an NMFC class yourself.
What is freight class and why does it matter?
Freight class is a standardized number from 50 to 500, set by the National Motor Freight Classification (NMFC), that groups commodities by how difficult and costly they are to ship. The lower the class, the cheaper the rate. The class is driven mostly by density—pounds per cubic foot—along with stowability, ease of handling, and liability to damage or theft. Dense, durable freight like bricks or canned goods falls into low classes (class 50–70), while light, bulky, fragile items like ping-pong balls or unassembled furniture land in high classes (class 250–500). To find density, divide the shipment’s total weight by its total cubic feet: a 500 lb pallet measuring 48″ × 40″ × 48″ occupies 53.3 cubic feet, giving a density of about 9.4 lb/ft³, which typically maps to class 110–125. Getting class right is essential—an incorrect class triggers a carrier reweigh and reclass, which means surprise charges after delivery.
LTL vs. partial vs. full truckload: which is cheaper?
The cheapest service depends almost entirely on how many pallets you are moving. LTL wins for 1–6 pallets, partial truckload (also called volume LTL) is most economical in the 6–18 pallet middle ground, and full truckload (FTL) is the best value once you fill most of a trailer. Partial truckload is the often-overlooked sweet spot: your freight rides on a shared trailer like LTL but skips the freight-class system and the hub-and-spoke handling, so it prices closer to FTL while you still pay only for your portion. The table below shows how the three services compare.
| Service | Pallet count | Pricing basis | Typical transit | Best for |
|---|---|---|---|---|
| LTL | 1–6 pallets | Freight class + weight + lane + fuel + accessorials | Slower (hub-and-spoke, multiple stops) | Small palletized shipments under ~5,000 lbs |
| Partial / Volume LTL | 6–18 pallets | Space + weight (no freight class), shared trailer | Faster than LTL (fewer handling touches) | Mid-size loads too big for LTL, too small for FTL |
| Full Truckload (FTL) | ~18–26 pallets / full trailer | Flat lane rate for the whole truck + fuel | Fastest (direct, point-to-point) | Large, heavy, time-sensitive, or fragile loads |
When speed matters more than cost—or when a single trailer can’t go fast enough—shippers compare truck options against air freight for expedited delivery. For most domestic freight, though, the choice is between LTL, partial, and full truckload (FTL) shipping, and the right call comes down to pallet count and timing.
How is a truck shipping rate built? A worked example
Consider a shipper moving 4 pallets of packaged auto parts, 3,200 lbs total, from Atlanta, GA to Dallas, TX. Here is how the LTL rate stacks up:
- Freight class: The parts measure out to roughly 12 lb/ft³ density, placing them in class 92.5.
- Base linehaul: The carrier’s tariff for class 92.5 at 3,200 lbs on the Atlanta–Dallas lane, after the negotiated discount, sets the base rate—say $560.
- Fuel surcharge: At a 28% fuel surcharge on the linehaul, add ~$157.
- Accessorials: The delivery is residential and needs a liftgate—add $95 (residential) + $75 (liftgate) = $170.
- All-in rate: $560 + $157 + $170 = $887.
Change one variable and the number moves: a commercial dock delivery drops the $170 in accessorials, and shipping the same freight as a partial load on a busy backhaul lane could undercut the LTL price entirely. This is exactly why an instant quoting engine beats a phone quote—it recalculates every variable in seconds across dozens of carriers, instead of relying on one rep’s tariff and memory.
What are accessorial charges and fuel surcharges?
Accessorial charges are fees for services beyond standard dock-to-dock pickup and delivery, and the fuel surcharge is a percentage added to the linehaul to cover diesel cost. Together they are the most common source of “surprise” freight bills, because they often aren’t quoted unless you flag the conditions at booking. The fuel surcharge floats weekly with the national average diesel price published by the U.S. Energy Information Administration. Common accessorials include liftgate service, residential or limited-access pickup and delivery, inside delivery, notification/appointment scheduling, reweigh and reclassification, and detention when a driver waits too long to load or unload. The fix is simple: declare every condition up front. ExFreight surfaces applicable freight accessorial charges inside the quote so the price you book is the price you pay.
Why do instant online truck rates beat phone quotes?
Instant online rates beat phone quotes because they are faster, more transparent, and account for live carrier capacity in real time. A phone quote depends on one broker pulling one carrier’s tariff during business hours; a digital platform queries dozens of carriers simultaneously, applies the current fuel surcharge and your specific accessorials, and shows you a ranked list of all-in prices in under a minute—any time of day. You see the trade-offs between price and transit yourself, choose the option that fits, and book in two clicks. Because the rate is built from your real dimensions and conditions, there’s far less risk of a reweigh, reclass, or accessorial showing up on the invoice weeks later.

Frequently asked questions
How are truck shipping rates calculated?
Truck shipping rates are calculated from the lane distance, the shipment’s weight and density, the freight class (for LTL), the service type, a fuel surcharge tied to diesel prices, and any accessorial fees. Carriers then adjust the base rate according to current capacity and lane balance. For LTL, freight class and billable weight drive most of the cost; for full truckload, a flat lane rate plus fuel applies. The most accurate way to see your exact number is to pull an instant online quote that calculates from your real dimensions.
What is the difference between LTL and FTL rates?
LTL rates apply when your freight shares trailer space with other shippers, so you pay only for the portion you use, priced by freight class, weight, and lane. FTL rates apply when you book an entire trailer, priced as a single flat rate for the lane plus fuel, regardless of how full the trailer is. LTL is cheaper for 1–6 pallets; FTL becomes the better value once you fill most of a truck. Partial truckload bridges the gap for mid-size loads.
What is a fuel surcharge on a truck shipment?
A fuel surcharge is a percentage added to the base linehaul rate to offset diesel fuel cost. It floats with the national average diesel price published weekly by the U.S. Energy Information Administration, so it rises and falls week to week. On LTL the surcharge is applied to the discounted base rate; on FTL it is typically calculated per mile. Because it changes constantly, a fuel surcharge is one reason an instant, up-to-date online quote reflects true current pricing better than a static phone estimate.
Why did my freight bill come back higher than my quote?
The most common reasons are an incorrect freight class, inaccurate weights or dimensions that triggered a carrier reweigh, or accessorial services that weren’t declared at booking—such as a liftgate, residential delivery, or limited-access location. Carriers inspect and re-rate shipments, and any discrepancy is billed back after delivery. The fix is to measure and weigh accurately and flag every delivery condition when you book. A density-based quoting engine that calculates class for you sharply reduces these post-delivery adjustments.
