A spot rate is the price for a single load booked now, based on today’s market. A contract rate is a price agreed in advance for moving freight on a lane again and again over a set period, so it stays the same even when the market rises or falls.
Most new dispatchers start in the spot market, booking loads from brokers one at a time. Knowing how contract freight works helps you understand why rates move, why some loads appear on load boards at all, and how a carrier can build steadier work over time.
Key takeaways
- Spot rates are set load by load and change with supply and demand. Contract rates are agreed ahead of time for a lane and period.
- When trucks are scarce, spot rates tend to rise. When trucks are plentiful, spot rates tend to fall.
- Spot freight offers flexibility and sometimes higher pay. Contract freight offers predictability.
- Many small carriers mix both: steady lanes when they can get them, spot loads to fill the gaps.
- Any numbers in this article are round examples only, not real market rates.
What is a spot rate in trucking?
A spot rate is a one-time price for one load, agreed close to when the freight needs to move. Brokers post spot loads on load boards or call carriers directly, and the dispatcher negotiates the rate on the phone.
No one sets spot rates. They come from supply and demand on that lane on that day. If many trucks want to leave an area and there is little freight, rates go down. If shippers need trucks quickly and few are available, rates go up. The season, the weather, fuel prices and holidays all play a part.
Once the load is booked, the agreed spot rate goes on the rate confirmation. Our guide to reading a rate confirmation shows what to check before the carrier signs.
What is a contract rate in trucking?
A contract rate is a price agreed in advance for a lane, usually for a set period such as several months or a year. Shippers often set these through a bidding process, where carriers and brokers quote rates for the lanes the shipper expects to move.
The contract usually spells out the lane, the expected volume, the equipment, the service level and how fuel is handled. Many contracts use a fuel surcharge that adjusts as fuel prices change, while the base rate stays the same.
A contract rate is a commitment on paper, but it is not always a guarantee of freight. Shippers may send fewer loads than expected, and carriers sometimes turn down contract loads when the spot market pays more. Both sides watch the market for that reason.
How do spot rates and contract rates compare?
| Point | Spot rate | Contract rate |
|---|---|---|
| What it covers | One load | Many loads on a lane over a period |
| When it is set | Close to pickup | Weeks or months ahead |
| How it moves | Changes with the daily market | Stays fixed for the term, apart from fuel adjustments |
| Where it comes from | Load boards and broker calls | Shipper bids, broker agreements, dedicated lanes |
| Main benefit for a carrier | Flexibility and the chance of higher pay when trucks are scarce | Predictable freight and planning |
| Main risk for a carrier | Low pay when freight is scarce | Locked into a rate when the market rises |
A worked example
The numbers below are an example only, not real or typical rates.
A carrier has a contract to haul one load a week on a lane for $2,000 a load. In the same weeks, spot loads on that lane move around:
- In a busy week, a similar spot load pays $2,400. The contract load pays $400 less than the spot market.
- In a slow week, a similar spot load pays $1,600. The contract load pays $400 more than the spot market, and it was booked without any searching.
Over a full year of ups and downs, the contract gives the carrier a steady base, while the spot market gives chances to earn more in busy periods. That is why many carriers want some of each. You can compare any two offers quickly with the rate per mile calculator on our free tools page.
Which should a new dispatcher focus on?
Most new dispatchers work mainly with spot freight, because that is where small carriers can find loads right away. Over time, steady work can grow out of it. Here is a practical order of steps:
- Learn the spot market first. Book loads, learn the lanes your carrier runs and keep notes on what loads paid.
- Know the carrier’s costs. A spot rate is only good if it is above the carrier’s cost per mile, so get that number from the carrier.
- Build repeat brokers. When you deliver on time and communicate well, some brokers will call you first or offer a regular lane.
- Ask about dedicated lanes. A broker with steady freight on a lane your carrier runs may agree a regular rate for it.
- Keep a balance. Even with steady lanes, leave room for spot loads so the truck is not empty between them.
When the market turns slow, these habits matter even more. Our article on navigating bad market conditions covers how dispatchers keep trucks moving when spot rates drop.
Why does the difference matter when you negotiate?
Knowing whether the market is tight or loose tells you how much room you have on a call. When brokers are struggling to find trucks, you can ask for more. When trucks are plentiful, you may need to accept less or look for a better load.
It also explains some broker behavior. A load that appears on a load board may be contract freight that the original carrier turned down. If the broker is covering it at a fixed price from the shipper, there may be less room to negotiate. To see how brokers fit into the picture, read truck dispatcher vs freight broker.
Frequently Asked Questions
Are spot rates always higher than contract rates?
No. Spot rates can be higher or lower than contract rates depending on the market. They tend to sit above contract rates when trucks are scarce and below them when trucks are easy to find.
Can a small carrier get contract freight?
Yes, though it usually takes time. Small carriers often start with regular lanes from brokers they have worked with, and some later win business directly from shippers.
What is a dedicated lane?
A dedicated lane is a route a carrier runs regularly for the same broker or shipper, often at an agreed rate. It gives the carrier predictable work and the customer a reliable truck.
Does a fuel surcharge apply to spot loads?
Spot loads are usually quoted as one all-in rate that already includes fuel. Contract rates more often list fuel separately so it can adjust as fuel prices change.
