XPO Freight Class Calculator
XPO is one of the largest LTL carriers in North America, and like every LTL carrier it rates shipments by NMFC freight class. Calculate yours below before you quote XPO.
Density-based estimate. Some commodities carry a fixed NMFC class — check our freight class by commodity pages.

How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |
| 15 – 22.5 | 70 |
| 13.5 – 15 | 77.5 |
| 12 – 13.5 | 85 |
| 10.5 – 12 | 92.5 |
| 9 – 10.5 | 100 |
| 8 – 9 | 110 |
| 7 – 8 | 125 |
| 6 – 7 | 150 |
| 5 – 6 | 175 |
| 4 – 5 | 200 |
| 3 – 4 | 250 |
| 2 – 3 | 300 |
| 1 – 2 | 400 |
| 0 – 1 | 500 |
How XPO uses freight class
After spinning off its logistics (GXO) and brokerage (RXO) businesses, XPO is now a pure-play LTL carrier with a dense North American network. Your XPO rate is built from freight class, weight, lane and accessorials — class being the single biggest factor. Getting the class right up front keeps an XPO quote accurate and avoids reclassification charges after the fact.
XPO after the GXO and RXO spin-offs
Today's XPO is a focused, pure-play LTL carrier — the result of spinning off its contract-logistics arm as GXO in 2021 and its brokerage as RXO in 2022. What's left is one of North America's largest less-than-truckload networks, running its own line-haul and hundreds of service centers. All of that freight is rated on the standard NMFC class scale, so the number you get here is the number XPO prices against.
Because XPO now lives or dies on LTL efficiency, it leans heavily on its own pricing and load-optimization technology — but none of that changes how your shipment is classified. Class, weight, lane and accessorials build the rate, with class the biggest lever. Get it right up front and an XPO quote holds; get it wrong and a dock inspection can reclassify it upward after the fact.
Is XPO’s freight class different?
No — and this trips a lot of shippers up. Freight class is set by the NMFC density scale, a single national standard. The class you calculate here is the same one XPO will rate against; what differs between carriers is the rate per class, the lanes they serve, and their accessorial fees — not the class itself. So calculate once, then compare XPO against other carriers on identical numbers with the freight quote builder.
Frequently asked questions
Does XPO use a different freight class than other carriers?
No. Freight class comes from the NMFC density scale, which is an industry standard — so the class for your shipment is the same whether you ship with XPO or anyone else. XPO simply applies that class to its own rates and lanes.
How do I find my XPO freight class?
Measure your shipment's dimensions and weight, work out the density (weight ÷ volume), and match it to the NMFC scale — the calculator above does exactly that. Confirm the final class and NMFC item number with XPO when you book.
Why does freight class matter for a XPO quote?
Class is usually the single biggest factor in an LTL rate. XPO is a pure-play LTL carrier; freight class is the largest driver of an XPO LTL rate. Getting it right before you request a quote keeps the rate accurate and avoids a costly reclassification later.
Is XPO the same company as GXO or RXO?
No — XPO spun those off. GXO (contract logistics, 2021) and RXO (brokerage, 2022) are now separate public companies. XPO itself is a pure-play LTL carrier.
How does XPO price an LTL shipment?
From freight class, weight, lane and accessorials, with class the largest single factor. Calculate your class first so the XPO rate you're quoted matches the freight you actually ship.
