Spot rates vs contact rates in logistics: when to use each

In logistics, choosing between spot and contract rates can mean the difference between making cost savings and exceeding your budget. While contract rates offer stability, spot rates provide flexibility. This guide explains which option to use in which situation, offering advice on how to optimize your freight strategy, and showing how a TMS can help you make better decisions intuitively.

What is a spot rate?

A spot rate is a one-off market price for a single shipment. The rate is affected by several variables, such as demand, gas and oil prices, or geopolitics, making it highly volatile. Manufacturers typically use spot rates for urgent shipments, spikes in production, when a carrier cannot cover a shipment, or to take advantage of price dips.

What is a contract rate?

A contract rate is a fixed, negotiated price agreed for a set period. It is usually based on the volume of freight, the requirements of the shipment, and the current spot rates. The longer the set contract term, the lower the rate.

Manufacturers use them for long-term planning, for agreed transit times, and to guarantee a certain amount of space each week or month.

How are spot rates calculated?

Spot rates reflect the current market price and are not related to the actual cost of the service. In LTL/FTL, they are highly volatile (+/- 25%), especially LTL prices. Spot rates can vary for many reasons:

• Current availability of resources (number of available trucks, empty space in trucks, available ferry places)
• Public holidays in different countries
• The general economic situation in countries (export/import imbalances, more loads out than in)
• Sharp changes in fuel prices

Spot rates depend on all of the above conditions. For example, if a carrier’s truck is missing five pallets on the return journey, they will want to find a low price to return it. If the truck is full, the driver can wait a day or two for a better offer to come home. When planning a trip, carriers need to consider how many trucks to send out, based on the number of outbound and inbound loads. Ultimately, they need to find a balance.

How are contract rates negotiated?

Typically, a manufacturer runs a tender by listing its transport routes and expected annual volumes. Carriers then submit bids, and each route is awarded to the bidder who offers the best combination of price, guaranteed capacity, and service. The agreed rate then remains in place for a set period of time (typically 6-36 months). For carriers, achieving a fixed price involves finding a balance, as each customer’s shipment structure varies over a given period of time (e.g. full loads or LTL, pallets or small cartons, more exports or imports). Carriers therefore try to optimize these flows so that trucks leave and return fully loaded.

Summary: Spot rates vs contract rates

Spot vs. contract rate: When to choose which?

One option is not necessarily better than the other. The best choice for manufacturers depends on various factors, such as freight volume, shipping frequency, and risk tolerance.

Use spot rates for:

• Unpredictable freight volume: If you only have a few shipments per month, spot rates offer greater flexibility.
• Urgent shipments: If you need same-day or next-day delivery, spot rates give you faster access to carriers. Contract rates involve more advance planning.
• Tactical or strategic reasons: If you want to secure the best current rate, using spot rates is a good tactical approach. Manufacturers with greater flexibility can benefit from this.
• New lanes: If you want to try out a new lane before committing to a contract, you can run a few test deliveries.
• Rate applicability: Spot rates are the current market rates, which apply to all customers. If you make spot bookings, you can expect consistent rates, with only minor variations based on specific factors.

Use contract rates for:

• Stable freight volume: If you are planning in the long term and have a stable supply chain, you can guarantee capacity and savings with contract rates.
• Better planning and budgeting: With contract rates, you can plan and budget for a specific period of time.
• Stronger partnerships: Working with certain carriers over a longer period of time can benefit both sides. You could get discounts and send shipments faster, while your contracted carriers would remain committed to your lanes, regardless of spikes in spot rates.
• Performance tracking: Having a reliable partner makes it easier to track business performance. Contract rates help you stabilize your shipping costs and enable you to calculate performance.
• Secure capacity: Capacity is not necessarily guaranteed by contracts, but carriers are more likely to secure it if you have a set contract.

6 tips for choosing between spot and contract rate

1. Analyze your shipment frequency. Which freight movements are stable and predictable, and which are irregular?
2. Combine price strategies. Use contract rates to cover your core volume and spot rates to cover spontaneous loads or seasonal fluctuations.
3. Book capacity in advance. Book your carriers early to avoid price increases during periods of high demand.
4. Track market indicators. Keep an eye on fuel prices and seasonal load availability across key routes.
5. Review your rate conditions. Check how fuel adjustments and volume flexibility clauses are defined in agreements.
6. Use historical data. Use a TMS to analyze past spot versus contract performance and identify lanes where spot rates consistently outperform contracts or vice versa.

How much freight volume do you need to get contract rates

To get contract rates, you can issue a formal transport tender. Any manufacturer can submit a bid, so this is not just for big companies. Also smaller companies can host bids to secure committed pricing.

What you need:

• Consistency in lanes
• A solid estimate of your volume for each lane
• The time frame you want the contract to cover

What do manufacturers need to run a transport tender

Whether you are hosting a large-scale annual network bid or a smaller one with just a few providers, there are a few things that you need to prepare.

• Understand your business, the goods you ship, and your operational routes: These factors influence the terms of your freight, including delivery time, service type, freight cost, payment deadlines, and credit limits.
• Select the right carriers: You will only achieve the best results if you send your tender to transport companies that are suitable for your needs. This is why it is important to analyse your current list of carriers and consider who else might be suitable for the new tender.
• Establish your carrier allocation strategy before conducting the transport tender: Think through and determine your strategy for selecting carriers and freight lines. The ability to serve major transport routes or customers with special requirements is important.
• Create a simple, clearly understandable tender document containing shipping conditions and a price list template: A typical tender document (RFP: request for proposal) explains what is expected from the carriers and describes your transport needs, such as the shipment profile, the nature of the goods, how frequently shipments will be made, and what should be included in the price (e.g. fuel surcharge, insurance and tolls).
• Record and evaluate your tender results using Cargoson's freight management software: Once the transport tender has been processed and the freight contracts negotiated, distribute the nominations to the carriers. Then apply the tender results in your ongoing partnership with your chosen carriers.

How a TMS supports with spot and contract rates

Rather than prices disappearing into email threads and spreadsheets that only one employee understands, you can identify contracted lanes with above market trends and include them in the next tender. Identify consistent spot quotes and convert them into contracts. Over time, use this data to manage your spot-to-contract ratio purposefully, rather than relying on habit or outdated spreadsheets.

What a TMS should offer for comparing spot and contract rates 

• Centralized freight rate database: All carrier rate sheets are stored in one centralized system. Once imported, every base rate and surcharge is available in one place, removing the need to search through emails or files. This comprehensive carrier rate management approach ensures that all pricing data is kept up to date.
• Automated surcharge updates: Fuel prices and taxes change regularly. A good system lets you update these once and recalculates all related rates instantly.
• Flexible rules engine: Modern rate engines can handle complex pricing logic. You can create surcharges that depend on weight, distance, route or other variables.
• Surcharge automation and instant calculations: When quoting a shipment, the system automatically adds up the base rate plus all relevant surcharges. No need for any manual calculations.

A TMS can save manufacturers and wholesalers who work with multiple carriers and rates time, improve cost control and reduce administrative burden.
