Flatbed rates per mile: current averages and how to set your minimum

Flatbed rates are the number every owner-operator watches and the one most often misread. Shippers comparing flatbed shipping rates see the same market from the other side. A national average is a weather report, not a price tag. This guide gives you the current, dated averages, explains what pushes flatbed freight rates up and down, and shows how to turn your own costs into a minimum rate you can say no with.

National flatbed rates, dated

These are DAT's national averages, the most widely quoted source for flatbed freight rates. They are average flatbed rates across all lanes and load types, per mile.

Source: DAT monthly release, Oct 13, 2026. The August and year-ago figures are worked back from the changes DAT reports. Notice that the linehaul part actually fell 10 cents in September while the all-in rate rose: the increase was fuel. The same release noted the national diesel average passed $6 a gallon for the first time.

Spot vs contract flatbed rates

Spot rates are what a broker pays for a load booked now. That is most of what an owner-operator with a load board or a dispatcher sees. Contract rates are agreed in advance between shippers and carriers or brokers for steady freight. In September 2026, flatbed contract ($4.04) sat above spot ($3.61), which is normal when diesel jumps faster than the spot market reprices.

For a one-truck carrier, spot is where you live, and DAT flatbed rates for spot are the fairest yardstick.

What moves flatbed rates

• Construction season. Flatbed demand usually builds in spring and summer and eases in winter, especially in the north (Trucking Dive, quoting DAT). More loads per truck means better rates.
• Steel and lumber markets. When mills ship more, there are more loads. Building material demand follows housing and commercial construction.
• Diesel. Fuel surcharges ride on the diesel price, so all-in flatbed load rates follow it up and down.
• Truck capacity. When trucks leave open deck, rates rise; when van drivers cross over in a slow van market, they fall.
• Lane balance. A load into a dead area pays more because you will deadhead out. A load out of a region full of trucks pays less.
• The load itself. Weight, tarps, permits, multiple stops and tight appointments all change the price.

Tarp and accessorial pay

Tarp pay is a separate line on the rate con, negotiated per load. There is no official national tarp rate, so ignore anyone quoting one as fact. The amount usually depends on tarp type and drop (a 4 ft smoke tarp vs an 8 ft lumber tarp), the size of the load and how badly the shipper wants it covered.

Other pay to get in writing before you roll:

• Detention: free time at pickup and delivery, then an hourly rate.
• Layover: a day rate if the load is not ready or the receiver cannot take it.
• TONU (truck order not used): paid if the load cancels after you are dispatched.
• Stop-off pay for each extra stop.
• Permit costs on oversize or overweight freight.

Missing accessorials are where many flatbed rates quietly drop by hundreds of dollars a week.

Flatbed rate per mile: set your own minimum

Flatbed trucking rates per mile only mean something next to your costs. A national average does not know your truck payment, insurance or mpg. Your minimum rate does. Build it like this:

1. Fixed costs per week (truck and trailer payments, insurance, phone, ELD) divided by the miles you expect to run.
2. Plus fuel per mile: diesel price divided by your mpg.
3. Plus maintenance and tires per mile.
4. Plus the profit per mile you need.
5. If you use a dispatcher, divide by (1 minus the fee), so the fee does not eat your profit.

Insurance is the line that varies most by carrier; our flatbed insurance guide covers what drives it. Then judge every load on its all-in rate per mile including deadhead, not the loaded miles alone. The flatbed rate calculator does that math for you, with tarp pay as its own input.

Reading a flatbed load rate on the board

When you look at a posted rate, ask:

• What is it per mile once I add the deadhead to pickup?
• Is tarp pay in the number or separate?
• How heavy is it, and does it fit my legal payload? Our trailer dimensions and weight limits guide shows how to work that out.
• Where does it leave me, and what pays out of there?
