Freight Comparison
Spot Rate vs Contract Rate: Which Freight Pricing Fits?
Use spot rates when volume is unpredictable, lanes change, or the market is soft and you want the lowest available price today. Use contract rates when you ship steady, repeatable volume and value budget certainty and guaranteed capacity over chasing the daily low. Most shippers run a blend: contracts for the base freight, spot for overflow and one-off lanes.
| Spot Rate | Contract Rate | |
|---|---|---|
| Pricing basis | Live market price quoted per load, based on current supply and demand. | Negotiated rate fixed per lane for a set term, usually 3 to 12 months. |
| Commitment | None. You quote and book load by load with no ongoing obligation. | Ongoing. Both sides commit to a lane, term, and expected volume. |
| Rate volatility | High. Prices swing with fuel, seasonality, weather, and capacity. | Low. The rate holds through the term regardless of market swings. |
| Volume fit | Best for sporadic, one-off, or overflow shipments. | Best for consistent, predictable, repeating lane volume. |
| Flexibility | Very high. Any lane, any day, add or drop freight instantly. | Lower. Locked to defined lanes and committed volume for the term. |
| Capacity in tight markets | Not guaranteed. You compete for trucks and prices spike. | Prioritized. Contracted freight gets served first when trucks are scarce. |
| Budget predictability | Hard to forecast. Costs move week to week. | Easy to forecast. Fixed rates make budgeting straightforward. |
| Best use case | Soft markets, new or seasonal lanes, and surge overflow. | Core, high-frequency lanes where reliability beats the daily low. |
Choose Spot Rate when…
- Your volume is irregular or seasonal
- You ship new or one-off lanes
- The market is soft and rates are falling
- You need overflow coverage above a contract
- You want the lowest price available today
Choose Contract Rate when…
- You ship steady, predictable volume
- You need firm budget certainty
- Guaranteed capacity matters in tight markets
- You run the same core lanes repeatedly
- You want a consistent carrier and service level
Frequently asked questions
Is a spot rate always cheaper than a contract rate?
No. In a soft market with excess trucks, spot rates often dip below contract rates. In a tight market, spot rates can spike well above contract, and shippers relying only on spot pay a premium or struggle to cover loads. Contracts trade the chance of a daily low for price stability and priority capacity.
How long does a contract rate last?
Freight contracts typically run 3 to 12 months, with 12 months common for annual bid cycles. The rate holds for the term, though fuel surcharges usually still adjust with a published index. Some contracts include renegotiation clauses if market conditions move sharply.
Can I use both spot and contract pricing?
Yes, and most shippers do. A common approach is to contract your steady base volume for reliability and price certainty, then use the spot market for overflow, new lanes, and seasonal surges. TAT brokers both, so we can hold your core lanes on contract and cover the rest at spot.
Why did my spot rate change so much week to week?
Spot rates reprice constantly against live supply and demand. Fuel costs, seasonal produce, weather events, holidays, and regional truck shortages all push rates up or down within days. That volatility is the tradeoff for the flexibility of booking load by load.
