Flatbed rates can vary a lot. It’s essential to pay close attention to flatbed shipping rates to make sure you are setting the right price for your load.

When preparing a quote or booking a load, you base flatbed shipping rates partly on your fixed costs. The weight, size, value, and classification of the freight will play a significant role in pricing, distance, and fuel price for your business.

However, other variables impact flatbed trucking rates. Storms can shut down lanes or require special handling. Trucks might also be redirected which can impact demand.

What’s happening in other industries affects flatbed trucking rates, too. When specific industries like construction or manufacturing are slow, other carriers may lower prices to keep their fleet busy. When, demand is high, everyone is able to command higher prices.

You can also charge higher flatbed freight rates that involve specific pickup and delivery requests. Layovers, wait time, driver detention, reconsignment, stop charges, and driver-assist charges all impact rates.

Taking these factors into account, how much do flatbed loads pay?

National average flatbed trucking rates

In June 2021, the national average flatbed trucking rates per mile was $3.15 for spot rates and $3.11 for contract rates. These rates are up more than a dollar for spot rates and 74 cents a mile for contract compared to last year’s lows in the same month.

How are flatbed ratings trending?

Flatbed shipping rates have been on an upward path ever since prices hit rock bottom in April 2020. While flatbed spot rates did not fall as sharply as van and reefer freight loads did last year, flatbed rates also recovered much more slowly.

Flatbed shipping demand closely aligns with construction and industrial production. In recent years, as these industries started to emerge from COVID-19 woes, flatbed trucking rates also began to rise.

Despite the slightly lower volume in 2021, there’s likely more upside to come as the construction industry continues to recover. Analysts are forecasting an average 15.6% growth rate in construction for 2021 compared to last year.

Industrial production is growing as well. After a general slowdown in 2020, industrial production rose by more than 16% in May and June. It’s expected to continue trending upward through 2022.

These trends suggest there will be increased demand for flatbed haulers. Higher demand could push flatbed trucking rates up as supply chains start returning to normal.

Eight factors that impact flatbed rates

  1. Supply and demand
  2. Load-to-truck ratios
  3. Freight weight
  4. Distance
  5. Destination
  6. Trailer type
  7. Fuel costs
  8. Accessorial charges

Supply and demand

Van and reefer rates have increased from higher demand. However, flatbed demand comes primarily from industry sectors with longer production cycles, so rates have risen more slowly. As those industries continue to recover, demand should gradually increase and impact flatbed trucking rates.

Load-to-truck ratios

Another gauge of supply and demand is the ratio of available loads vs. available trucks. Load-to-truck ratios are an excellent way to assess current demand and capacity. In February 2020, the load to truck ratio rose to 7.54. That means more than seven loads were available for every truck listed as available. That’s the highest rate since June of 2018.

Freight weight

Freight costs are calculated per hundredweight (CWT). While heavier cargo will cost less per hundred pounds, it will command higher prices overall. The weight of cargo also impacts fuel costs. The higher the freight weight, the more fuel it takes to move that freight.


The distance drivers travel always impacts the flatbed trucking rates you charge. The greater the distance and the smaller the time window, the higher the rates will be.


If you or your drivers are traveling outside your traditional lanes or service routes, adding additional fees may be addeed. If loads need to be offloaded or transferred to shipping centers, it will take more time and require extra wait time.

Trailer type

Rates will also vary depending on the availability of trailers and the type of flatbed truck you need for a specific cargo. Different types of trailers include:

  • Standard flatbed
  • Single-drop or dropdeck flatbed trailers
  • Double-drop flatbed trailers
  • Lowboys
  • Stretch or extendable trailers
  • Side-kit flatbeds
  • Curtain-side flatbeds

Fuel costs

Diesel fuel costs and taxes are different within each region and state. Your fuel costs will be determined by your shipping lane and where trucks have to travel to get to their destination.

Like freight prices, fuel costs are also continuing to rise. In September 2021, the cost of diesel was at its highest point since 2018 at $3.73 a gallon — an increase of 73 cents a gallon from the beginning of the year.

Accessorial charges

Accessorial charges are fees shippers or brokers will pay for services beyond the typical pickup, transport, and delivery. These extra services can include:

  • Loading and unloading
  • Appointment or timed deliveries
  • Layovers
  • Limited access delivery
  • Metro pickups or deliveries
  • After-hours deliveries
  • Hazardous material transportation
  • Diversion miles
  • Oversized or overlength loads
  • Waiting time or detention
  • Additional stops
  • Storage
  • Liftgate service
