Short answer
A spot rate is the price to move one load now, negotiated at booking instead of set by contract. Spot rates change daily with truck supply, load volume, fuel, season, and weather. Contract rates are agreed ahead of time for a lane and period. When spot rates climb above contract rates, brokers’ margins on contracted freight get squeezed.
Spot rate vs contract rate
| Spot rate | Contract rate | |
|---|---|---|
| When it’s set | At booking, for one load | Ahead of time, often in a bid or annual agreement |
| How long it lasts | That load only | A set period, such as a quarter or a year |
| Price movement | Changes with the market day to day | Fixed, sometimes with a fuel surcharge or review clause |
| Commitment | None beyond the load | Expected volume and tender acceptance |
| Common use | Overflow, one-off, and rejected contract freight | Recurring lanes with steady volume |
What moves spot rates
- Capacity vs demand. More loads chasing fewer trucks in a market pushes rates up. Load boards track this as a load-to-truck ratio.
- Season. Produce harvests, holiday retail peaks, and end-of-quarter pushes tighten capacity in specific regions.
- Weather and disruptions. Storms, hurricanes, and port or rail slowdowns pull trucks out of normal patterns.
- Fuel. Diesel cost flows into what carriers will accept.
- Location. A load that picks up where few trucks empty costs more, because carriers price in deadhead miles.
How brokers work the spot market
A broker lives on both sides of the spot rate. On the sell side, it quotes shippers for one-off loads and for contract freight that the shipper’s primary carrier rejected. On the buy side, it books carriers at whatever the market will bear that day.
Spot truckload quotes need a buffer. If the booked carrier falls off, the recovery truck is usually booked on short notice at a higher rate, and the rate con for the new carrier sets the new cost.
Spot freight also carries fraud risk. A carrier offering well under market on a hot load deserves a harder look for double brokering or identity theft.
Example: a contract lane when spot rates rise
Example, with illustrative numbers. In January a broker agrees to a contract rate of $2,100 per load on a dry van lane. Carriers are taking the lane for $1,750.
- January margin: $350, or 16.7%
- October: spot carrier cost on the lane rises to $2,050. Margin falls to $50, or 2.4%.
- A carrier falls off, and the recovery truck costs $2,250. The broker loses $150 on that load.
The customer’s rate stayed at $2,100 while the market moved. That’s why many contracts include fuel surcharges or a rate review clause.
Common spot rate mistakes
- Quoting today’s load from last week’s lane rate.
- Locking a year-long contract rate with no fuel or review terms.
- Booking the cheapest carrier without checking authority, insurance, and contact details.
- Pricing to the pickup city without checking where trucks actually empty nearby.
- Not tagging loads as spot or contract, so margin reports hide which one is losing money.
How FreightVero handles it
FreightVero doesn’t pull spot market rates today. The DAT integration is planned. What’s live in the broker TMS is the load record behind the math: the carrier’s rate on a versioned rate con, carrier swap history when a truck falls off, and margin reporting across your loads.
