Running a truck costs more in 2026 than at any point on record. If you’re managing 1 to 10 trucks, every extra cent per mile eats directly into your margin.
This guide breaks down where fleet costs come from and how to calculate your real numbers. And it covers the strategies that actually move them, from fuel and maintenance to financing and insurance.
TL;DR
- The average cost to run a truck hit $2.336 per mile in 2025, the highest on record, according to ATRI.
- Diesel prices have jumped over $1.70 a gallon in the past year, so fuel savings matter more than ever.
- Tracking cost per mile by truck, not by fleet, is the fastest way to spot which vehicles are losing you money.
- Idling, driver behavior, and preventive maintenance are the quickest wins. Financing and insurance decisions drive the bigger, longer-term savings.
What Is Driving Up Fleet Costs Right Now?
Fleet management costs are rising because almost every major expense category went up in 2025. Fixed costs like insurance stay fairly steady. Variable costs and indirect costs, fuel, tolls, and repairs, are climbing fastest for fleet managers and owner-operators alike.
ATRI’s 2026 report found average operating costs to run a truck reached $2.336 per mile in 2025. That’s up 3.4% from $2.260 the year before, the highest per-mile cost on record.
Repair and maintenance costs rose 8.6% to $0.404 per mile. Aging trucks are especially prone to these higher maintenance costs as parts wear out.
Tolls jumped 13.2%, driver benefits climbed 6.6%, and tire costs rose 6.4%. Truck and trailer lease payments also increased, up 3.6% to roughly $0.40 per mile.
Small fleets spent less on vehicle acquisition in 2025 than in 2024. That’s a sign many are holding off on new fleet vehicles while operational costs settle.
Diesel prices also spiked hard in 2026. The EIA’s weekly survey put the national average retail diesel price at $5.454 per gallon in mid-August. That’s up more than $1.70 from a year earlier. That swing alone can wipe out a season’s margin for a small fleet.

How Much Does It Cost to Run Your Truck?
The two numbers that matter most are total cost of ownership (TCO) and cost per mile (CPM).
TCO adds up everything you spend on a truck over its vehicle life. That’s purchase or financing costs, fuel, maintenance, insurance, tolls, administrative costs, and driver pay, minus resale value.
For example, say you finance a truck for $150,000 and spend $400,000 more on fuel, repairs, and insurance over five years. Your TCO is $550,000 minus whatever you sell it for at the end.
CPM divides that total by the miles the truck drove over the same period.
A truck with a $550,000 TCO that ran 500,000 miles over five years costs $1.10 per mile to run. That single number tells you whether a load, a lane, or a rate is actually worth taking.
Here’s what CPM and TCO help you do:
- Spot the one truck losing money on repairs before it drains your cash.
- Decide whether a load or lane covers your real cost to run, not just your fuel and driver pay.
- Know when a truck has crossed from a cost-efficient asset into a money pit, so you can plan a repair, sale, or replacement instead of reacting to a breakdown.
- Compare financing, insurance, or leasing offers against your actual numbers instead of guessing.
Running the math per truck, every month, is the only way to catch a problem while it’s still cheap.
5 Best Strategies to Reduce Costs for Small Fleets
The strategies that move the needle fall into five areas: fuel, maintenance, technology, financing, and insurance. Some pay off within weeks. Others take longer but deliver bigger, more lasting savings.
Here’s how to tackle each one to help reduce fleet expenses.

1. Cut Fuel Costs
Fuel is one of the highest costs in your budget, and it’s tied directly to fuel consumption for every truck.
Start by cutting excessive idling. The U.S. Department of Energy estimates that idling wastes more than 6 billion gallons of fuel every year across U.S. vehicles. That costs over $11 billion at a $2-per-gallon baseline.
Cutting idling during rest periods is one of the simplest ways to reduce fuel consumption.
Next, address driving habits. Aggressive driving, speeding, hard braking, and rapid acceleration can lower fuel economy by 15% to 30% at highway speeds. In stop-and-go traffic, the loss climbs to 10% to 40%.
Learning to anticipate traffic flow and brake gradually protects your fuel budget. If you’re due for a replacement, moving toward more fuel-efficient vehicles compounds these savings over time.
A few other ways to reduce fleet costs pay off quickly, without new equipment:
- Keep tires properly inflated and aligned. Proper tire care is one of the cheapest ways to improve fuel efficiency.
- Use fuel cards to track spending by driver and station. This helps you optimize fuel consumption and catch unusual purchases early.
- Plan routes more efficiently to cut empty miles and avoid unnecessary detours.
Together, these habits add up to real fleet efficiency gains for smaller operations. We break down more tactics in our guide to fuel-efficiency strategies for semi-trucks.
2. Lower Maintenance and Repair Costs
You can lower repair costs by catching small problems before they become expensive ones. Reactive repairs, the kind that follow a breakdown, almost always cost more than a scheduled fix.
A single costly breakdown can spiral into thousands of dollars in emergency repair costs. On top of that, you lose days waiting on a shop appointment.
A proactive fleet maintenance program of oil changes, tire rotations, and inspections keeps small issues from becoming major failures.
Many small fleets are updating their maintenance procedures to include predictive maintenance. That means using engine hours and sensor data to schedule maintenance before a part fails. Predictive maintenance also helps you avoid unnecessary service, since parts get replaced based on real wear.
A clean maintenance history for each truck also helps you spot patterns and avoid repeat maintenance expenses.
Train yourself or your drivers to catch early warning signs, too. A failing carrier bearing, for example, often gives off clear signals before it fails. Catching it early is far cheaper than a roadside breakdown and helps protect the truck’s vehicle lifespan.
Set up a repeatable pre-trip and maintenance routine so vehicle repairs don’t pile up unnoticed.

3. Use Telematics and GPS Tracking
Telematics data, GPS tracking, and fleet management software give you the cost visibility to see where money is being wasted.
These systems combine fleet tracking, vehicle location, and driver behavior data in real time. That lets you monitor driver behavior without guessing from fuel receipts and mileage logs.
Telematics helps in several ways:
- It can trigger maintenance alerts based on vehicle condition, flagging problems before they become a shop visit.
- It can lower fuel costs. Fleets using GPS tracking reported an average 12% decrease in fuel costs. Much of that comes from catching idling and aggressive driving early.
- It supports route planning and optimizing routes, cutting empty miles and out-of-route stops that quietly drain your fuel budget.
Together, these capabilities raise operational efficiency without adding headcount.
For small fleets, the value is in catching patterns early. That might be a truck with poor vehicle utilization or weak asset utilization. It could also be a route that runs long or a driver who brakes hard.
Left unaddressed, each adds up over a year.
4. Review Financing and Leasing Decisions
Every truck eventually reaches a point where repair and maintenance costs outpace what it can still earn. Holding onto an aging truck past that point usually costs more than replacing it, even with a new loan payment. When you do replace it, how you pay for the truck matters as much as when you buy it.
Start by reviewing current commercial truck financing rates before you commit to a loan. Rates shift, and locking in an old quote can cost you thousands over the life of the loan.
Leasing a semi-truck instead of buying is worth considering too. It’s especially useful if cash is tight or you won’t keep the truck long. As a rule of thumb, financing suits fleets running the truck for years with cash to weather a slow month. Leasing suits fleets that want to preserve cash flow now or avoid the resale risk of owning it.

5. Lower Insurance Costs
You lower fleet insurance costs mainly by reducing risk and proving it. Insurers increasingly look at real driving data instead of just claims history. Fleets that adopt safer habits often qualify for lower insurance premiums over time.
Dash cams are one direct way to support this. They provide evidence in the event of an incident, which can protect you from liability. Over time, that evidence supports a case for lower premiums. Our guide to the best dash cams for semi trucks covers what to look for.
Beyond equipment, consistent driver training and a clean maintenance record both shape how insurers assess your risk.
Shopping your policy every year or two, rather than renewing automatically, helps you avoid paying more than the market rate.
Where Should You Start Cutting Fleet Costs Today?
Start with your numbers. Calculate cost per mile for each truck, not just your fleet as a whole. That’s the fastest way to reduce costs you can’t otherwise see. From there, tackle idling, driver behavior, and fuel card monitoring first. Those usually show results within weeks.
Preventive maintenance and telematics take longer to pay off, but they save money more consistently over time. Financing and insurance decisions matter most over the life of the truck. Review them at least once a year instead of letting old terms roll forward.
