8 Ways to Lower Your LTL Freight Costs
June 26, 2026 · Updated September 26, 2026 · 6 min read
An LTL bill is built from a few inputs, and most of them are in your hands. The eight levers below come from the rules in the carriers' own tariffs, the documents that decide what you are charged. None of them need a new contract. In short: get the class right, ship denser, keep stackable freight stackable, put the true weight on the bill of lading, and send every carrier the same numbers.
1. Get your freight class right
Class sets the rate per 100 lb, and for most freight it comes from density. Measure the loaded pallet, pallet included, weigh it, and check the class with the freight class calculator before you book, instead of copying a class from an old bill of lading.
2. Ship denser
Every pound you fit into the same space lowers the class, and a denser load is also less likely to trip the minimum charges below. Stack to a stable, level top, fill gaps, and put loose cartons on fewer, fuller pallets. The pallet calculator shows the best carton pattern for your pallet.
3. Stay clear of the low-density minimum
Every major LTL carrier charges big, light shipments as if each cubic foot weighed 6 lb. The line differs by carrier: Estes applies it to anything over 350 cubic feet, while XPO, Old Dominion and Saia start at 350 cubic feet for very light freight and at 750 for the rest, and FedEx Freight, TForce and R+L at 750. If your shipment is close to one of those lines, a little less height or a little more weight can keep it on the normal rate.
4. Don't mark stackable freight “do not stack”
When nothing can be loaded on top of your freight, carriers measure it at a fixed height instead of its real one: 84 inches at Estes and FedEx Freight, 95 inches at R+L, 96 inches at Old Dominion, and 8 feet at TForce. XPO measures anything 75 inches or taller at 96 inches. A 60-inch pallet billed as 84 or 96 inches is billed for air. Only use the label when the freight really can't take weight, and keep pallets under the carrier's height lines where you can.
5. Put the right weight and description on the bill of lading
Corrections cost money on top of the new charges: $50.70 at XPO, $44 at Saia, $40 at R+L and $25 at Estes for a weight that goes up 100 lb or more. A vague description is expensive too: XPO bills class 150 first, and Estes charges $20 to inspect. Weigh on a real scale and use the exact commodity description.
6. Watch the capacity-load lines
Past a certain length or weight, LTL carriers charge for the space as a block: from 14 to 21 feet of trailer or 15,000 to 20,000 lb, depending on the carrier. If your shipment is near those lines, ask for a volume LTL quote and a truckload quote as well. LTL vs FTL explains where each one wins.
7. Only pay for speed and extras you need
Guaranteed delivery is priced as a share of your linehaul: Saia, for example, adds 25% for delivery by 5 p.m., 35% by noon and 45% by 10 a.m. Extra services such as liftgate, residential delivery and appointments are each added on top. Book them when the shipment needs them, not by habit, and ship dock to dock where you can. Our guide to accessorial charges explains each one.
8. Quote several carriers with the same numbers
Rates differ a lot by carrier and lane, but a comparison only works when every carrier gets the same shipment. Build the request once in the freight quote builder and send it to several, so the prices come back line for line.
Frequently asked questions
What is the biggest factor in LTL freight cost?
Freight class, which for most freight comes from density: weight divided by cubic feet. A denser shipment rates a lower class and a lower rate, so getting the class right and shipping dense are the two biggest levers.
Does a "do not stack" label cost more?
Often, yes. Carriers measure freight that nothing can go on top of at a fixed height: 84 inches at Estes and FedEx Freight, 96 inches at Old Dominion and XPO, 95 inches at R+L. That extra height can push a shipment into a low-density minimum charge.
What does it cost if the carrier reweighs or reclasses my freight?
On top of the corrected freight charge, the tariffs add a fee: $50.70 at XPO when the linehaul rises $1 or more, $44 at Saia, $40 at R+L when charges change by $10 or more, and $25 at Estes when the weight rises 100 lb or more.
How do I compare LTL carriers fairly?
Send every carrier the same shipment: class, dimensions, weight, lane and extra services. If the inputs differ, the quotes can't be compared. Building one request and reusing it keeps the comparison honest.
