New brokers often treat rates as just a number — what does it cost to move this load right now? Experienced brokers understand that the rate type shapes the entire business relationship, the risk you're carrying, and how you manage capacity over time.
How Spot Rates Work
A spot rate is a one-time price for a specific load. When a shipper needs a truck to move a load from Memphis to Atlanta tomorrow, they post it (or call their broker), and the broker goes to market to find a carrier at a price that leaves margin.
Spot rates are inherently volatile. They track supply and demand in real time — when there are more trucks than loads, rates fall. When capacity tightens, rates spike. During 2021 and early 2022, spot rates on major lanes were 40–60% above their pre-pandemic levels. By late 2022 and through 2023, the market had inverted so hard that many carriers were operating below their all-in costs.
For brokers, the spot market has a simple dynamic: when capacity is tight, you can find margin; when it's loose, you're competing against every other broker for scraps.
What makes spot pricing work for brokers:
- Faster feedback loop — you price each load individually against real market data
- No long-term commitment — you're not locked into rates that go underwater
- Flexibility to serve shippers with irregular freight
What makes spot pricing hard:
- Margin compression when capacity is abundant
- Carrier relationships suffer if you're constantly re-shopping every load
- Shippers who are spot-only tend to price-shop aggressively
How Contract Rates Work
Contract rates are pre-negotiated rates for recurring freight, typically covering specific lanes and freight types for 6–12 months. A shipper agrees to tender a certain number of loads per week on a lane at a fixed rate; the broker commits to covering those loads at that rate.
The annual freight "bid season" (typically Q4 for the following year, though it varies by industry) is when most large shippers put their contract freight out to bid. Brokers submit rates, shippers award lanes to the carriers and brokers with the best combination of price and service score.
What makes contract pricing work for brokers:
- Predictable volume — you know what freight is coming every week
- Relationship stickiness — a shipper won't easily replace a broker mid-contract
- Carrier relationships become deeper — you can commit load volume to carriers in exchange for capacity commitment
What makes contract pricing hard:
- You're locked into rates that may go wrong if the market moves against you
- In a capacity crunch, covering contract freight at contract rates while spot rates are 30% higher means you're losing money on every load
- Winning contract business typically requires demonstrating operational capability and service history
The Market Cycle Matters Enormously
The strategic value of spot vs. contract isn't constant — it depends heavily on where you are in the freight market cycle.
In a soft market (more trucks than loads, falling rates):
- Spot rates fall faster than contract rates
- A broker with contract customers can still turn margin because shippers are paying contract prices while carrier costs are dropping
- The spot market is brutal for brokers without contract relationships
In a tight market (more loads than trucks, rising rates):
- Spot rates spike above contract rates
- Brokers with contract commitments face a painful choice: cover loads at rates that may be underwater, or renegotiate and risk the relationship
- Shippers with contract rates are insulated — brokers may need to honor rates at a loss or use force majeure provisions
The 2021–2022 capacity crunch showed this dynamic in painful detail. Brokers who had committed to contract rates at 2020 prices were suddenly covering loads at $2,000+ for lanes they'd contracted at $1,200. Many burned through margin reserves or broke contracts entirely.
How Experienced Brokers Structure Their Book
The conventional wisdom among experienced brokers is to build a mixed book — some contract, some spot — where the contract business provides a stable revenue floor and the spot business lets you capture upside when the market tightens.
The exact split depends on your risk tolerance, capitalization, and carrier network. A heavily capitalized broker can afford more contract exposure because they can weather short periods of below-margin coverage. A smaller broker with thin reserves should be more cautious about how much contract volume they take on.
Some brokers structure their contract commitments with explicit language about market escalation clauses — provisions that allow rate renegotiation if fuel prices or market rates move beyond a defined threshold. These are more common in the current market environment after the 2021–2022 volatility.
Margin Structures Differ
On spot freight, the margin math is simple: carrier rate subtracted from customer rate equals your gross margin. A load billed at $2,000 with a carrier cost of $1,600 yields $400 or 20% gross margin.
On contract freight, the math is the same formula but the risk is different. You committed to $2,000 to the shipper 90 days ago when the market was different. If carrier costs have risen to $1,900, you're making $100 — or if they've risen to $2,100, you're covering at a loss.
Sophisticated brokers use rate benchmarking tools (DAT RateView, Truckstop.com market data) to check their contract rates against current market conditions continuously, not just at bid time.
Frequently Asked Questions
Should new freight brokers start with spot or contract business?
Almost always spot. You don't have the operational track record to win contract awards from major shippers, and contract commitments carry risk that new brokers often underestimate. Build your book on spot freight, develop your carrier relationships, and pursue contract business once you have the operational track record and capitalization to back it up.
What is a "spot board" or "spot desk"?
A spot desk or spot board is a team within a brokerage that handles transactional, one-time freight. Many larger brokerages have separate contract desks (managing ongoing bid awards) and spot desks (managing overflow and opportunistic freight). For smaller brokerages, one person or team handles both.
How far in advance can spot rates be quoted?
Reliably, 1–3 days. Seven-day spot quotes can be provided but the accuracy drops significantly — fuel prices, weather, and regional capacity can all shift meaningfully in a week. Contract rates account for this uncertainty by building buffer into the price.
What happens if a broker can't cover a contracted load?
This is a serious situation. The broker may need to source coverage at a loss, use a third-party broker to find capacity (double-brokering with disclosure), or have a very difficult conversation with the shipper about failure to cover. Repeated failures to cover contracted freight will end the relationship and potentially trigger contractual penalties.
Is there a minimum volume for contract pricing to make sense?
For the shipper, contract pricing typically makes sense when they're shipping multiple times per week on consistent lanes. For one-off or irregular freight, spot pricing is more practical. As a rough benchmark, 3+ loads per week on a lane is usually the threshold where contract pricing starts to benefit both parties.
