How to Compare Contracted Freight With Spot-Market Opportunities
Contract freight offers stability and spot freight offers flexibility, sometimes at a higher rate. A fleet should know what each really earns before choosing the mix.
1. The business problem
Is the spot market better than our contracts, or just louder?
Spot loads can pay more per mile in a tight market and less in a loose one. Contract freight pays steadier rates and keeps trucks busy, but may be priced below the market peak.
The comparison is not rate alone. Spot freight tends to bring more empty miles, more dispatch effort and more volatility, while contracts bring commitments and sometimes service obligations.
2. What the evidence can reveal
A fair comparison puts both types on the same footing:
- Calculated Revenue per loaded mile, over time, for contract and spot.
- Calculated Contribution margin after direct cost, including deadhead.
- Calculated Volatility: how much the rate and volume move quarter to quarter.
- Information gap Sales and dispatch effort per load, and the cost of finding spot freight.
The goal is the mix that meets the fleet’s profit and stability needs, not the highest rate on any one load.
3. Investigate the problem
In the synthetic carrier, cross-country spot is the clearest spot-like lane, and Southeast dedicated is the clearest contract-like lane. Calculated Spot grew miles 14.5% while its rate per mile slipped 1.8% to $2.14, and its contribution margin fell from 20.8% to 14.8%. Southeast dedicated held its rate at $2.33 and its margin at 27.0%, down only 1.5 pts.
Hypothesis The spot lane grew by taking more freight at lower rates, a pattern typical of a loosening spot market, though the data cannot confirm that. A rate that falls while volume rises is a signal that growth is being bought. Information gap Contract terms, rate-reset dates and market indices are not in the demo.
Illustrative A hypothetical makes the trade-off concrete. If the spot lane earns $2.14 a mile against direct costs of about $1.83 a mile, the contribution is about 31 cents a mile. If a spot rate fell 3 cents, contribution would fall by about a tenth, and the empty miles needed to reach spot loads are not counted in that figure.
4. Explore the interactive experience
Investigate it yourself.
Fleet Economics Dashboard: a lane-level dashboard with empty-mile share, a scenario simulator for rate, fuel, miles and empty miles, evidence-linked answers from APIS, and a sample brief, all on synthetic data.
The experience below is built on a synthetic carrier, “Demo Freight Co.,” analyzed by lane. It has no customer-level, vehicle-level or delivery-level records, so lanes are used to show the method. Nothing in it is real.
- Select Cross-country spot and then Southeast dedicated. Compare rate per mile, margin and the change in each.
- In the Scenario tab, raise loaded miles by 5% and the rate per mile by 0%. How much does extra volume at the same rate add?
- Ask APIS how contract and spot lanes compare.
5. Evaluate possible solutions
Mix decisions balance profit with stability and effort.
6. What leadership should do next
Questions to answer
- What does each channel earn after all costs?
- How volatile is each?
- How much dispatch effort does spot take?
- What mix suits our cash flow?
Data to gather
- Revenue and cost by channel
- Contract terms
- Market rate indices
- Dispatch effort
Steps to take
- Compare channels on margin.
- Set a spot floor.
- Review contract reset dates.
- Rebalance each quarter.
7. Engage Two Pillars
Understand the Economics of Your Fleet
Two Pillars can help carriers, fleet operators, brokers and logistics businesses investigate lane, vehicle, customer, cost and expansion economics using your own data. A good first step is a channel analysis that compares contract and spot freight on the same basis.
