Knowing your cost per mile is step one. Step two is finding loads that beat it by a healthy margin. Our dispatchers do that every day.

Cost Per Mile Industry Benchmarks
| Excellent (well-managed) | < $1.50/mile | low debt, fuel-efficient routes |
| Good (owner-operator avg) | $1.50–$1.80/mile | ATBS 2025 median |
| Average | $1.80–$2.10/mile | national owner-operator range |
| Watch closely | $2.10–$2.40/mile | thin margins at market rates |
| Unsustainable at market rates | > $2.40/mile | requires rate renegotiation |

Quick Answer
The national average cost per mile for owner-operators runs $1.65–$2.10 depending on truck payment, fuel price, and insurance. Most operators underestimate their true CPM by $0.15–$0.25/mile because they miss maintenance reserves and full fixed-cost allocation. Enter your actual expenses below to find your real number.
The number that determines whether you're making money or just staying busy
Most drivers think about trucking income in terms of gross revenue — what the broker paid, what the load rate was, what they deposited in the bank. The problem is that gross revenue is nearly meaningless on its own. The only number that tells you whether a load was actually profitable is your cost per mile.
This per-mile operating cost equals the total operating cost of your trucking business divided by the total miles you drive. If it costs you $18,200 to run your truck this month and you drove 10,000 miles, your per-mile operating cost is $1.82. Every mile you haul at rates above $1.82 generates profit. Every mile you haul below $1.82 generates a loss — even if that load paid $2,200.
The mistake is only counting the obvious costs — fuel and truck payment. Those are real costs, but they're typically only 45–55% of your total per-mile cost structure. When you add insurance, maintenance, tires, permits, ELD, accounting, phone, health insurance, and a realistic depreciation reserve, the number is often 40–60% higher than what drivers estimated.
Here's a common example. A driver thinks their per-mile operating cost is about $1.10 — fuel at $0.58 and truck payment at $0.32 per mile. When they run the full calculation, the actual number comes out at $1.78. They've been accepting loads at $1.50/mile thinking they're making money. They're not. They've been losing $0.28/mile — $2,800/month — and drawing down on savings without realizing it.
Once you know your rate floor, you have a hard number for load negotiations. Your minimum acceptable rate is your per-mile rate floor plus whatever profit margin you're targeting.
If your operating cost is $1.78 and you're targeting a 20% profit margin, your minimum rate is: $1.78 ÷ 0.80 = $2.23/mile. Any load below $2.23 either gets negotiated up or declined. That's not being difficult — that's running a business.
The drivers who consistently hit 20%+ margins aren't necessarily better at finding loads. They're better at knowing which loads to refuse.
Your per-mile operating cost isn't static. It changes when diesel prices move, when you drive more or fewer miles, when a big maintenance bill hits, or when insurance renews. That's why this should be a calculation you run monthly — not once when you start and never again. Use this tool every month to keep your floor number current.
Fixed costs, variable costs, and the expenses most drivers forget to count
Understanding your true per-mile expense means accounting for every dollar that goes out. This section walks through each cost category, what realistic numbers look like, and which expenses most owner-operators either miss entirely or consistently underestimate.
Fixed costs are the same every month regardless of whether you run 6,000 miles or 12,000 miles. They're your baseline burn rate — what it costs just to exist as an owner-operator before you turn a wheel.
These scale directly with miles driven.
Truck replacement reserve is a real per-mile expense that rarely shows up in informal calculations. A Class 8 semi purchased at $120,000 and traded or sold at $60,000 in five years generates $24,000/year in unrealized depreciation — $2.40/mile at 10,000 miles/month if you're tracking total cost of ownership correctly. Operators who don't build this into their per-mile cost structure are understating their true cost, which means understating the minimum rate they need to stay viable long-term.
Self-employment and income tax reserves should also factor into your all-in operating cost if you're treating this as your true per-mile figure. At a combined 30–35% effective rate on net income, every dollar of profit above your expenses has a $0.30–$0.35 tax obligation attached. Experienced owner-operators set aside a tax reserve amount monthly and treat it as a cost of business, not a surprise at year-end.
ATBS data on what lean, average, and high-cost operators actually spend per mile
Knowing your own per-mile operating cost is the first step. The second step is understanding where that number sits relative to the rest of the industry — because your rate floor doesn't exist in isolation. It determines the rate you need to be profitable, which determines which loads you can accept, which determines how competitive you can be in the market.
ATBS, which manages accounting for more than 15,000 owner-operators, publishes operating cost benchmarks that are the most reliable industry data available. The ranges below reflect their 2025–2026 data adjusted for current fuel and insurance costs.
These benchmarks apply most directly to dry van operations. Other equipment types have different cost profiles.
The benchmark equipment. Good fuel economy (6.0–7.0 MPG), moderate maintenance costs, widely available loads. Most operators in the $1.60–$2.00/mile range are running dry van.
Higher fuel cost (5.0–5.8 MPG), higher maintenance costs (reefer unit adds $0.02–$0.05/mile), higher insurance. Effective per-mile operating cost runs $0.15–$0.25/mile above equivalent dry van. This is why reefer rates are typically $0.20–$0.40/mile higher — the market has partially priced in the cost difference.
Similar fuel economy to dry van, but higher insurance (oversized load exposure), specialized permits, tarping equipment maintenance, and often more detention time. Total per-mile running costs are similar to or slightly above reefer.
Lower absolute monthly costs but often higher per-mile costs due to worse fuel economy (pickup truck + trailer gets 8–13 MPG, but trailer weight limits mean more trips per ton of freight). The math works when you have consistent, premium regional freight. It breaks when you're running commodity freight competing against full-size semis.
First, identify which cost category is driving the high number. If it's the truck payment, that's a long-term problem that fixes itself over time as the loan balance drops — unless the payment is so high you can't survive the wait. If it's insurance, check your authority age and record and re-shop at renewal. If it's fuel, look hard at MPG (tire pressure, speed, idle time) and whether a fuel card discount program makes sense for your volume.
At $2.00+ per-mile operating cost, you need to be running lanes that consistently pay $2.50/mile or better to maintain a viable margin. That means being more selective — both about load sources and about brokers. Operators at this per-mile cost structure who are accepting everything on the load board because they feel like they can't afford to say no are usually in a spiral that gets worse before it gets better.
Getting your per-mile operating cost right — and keeping it current — is the first step toward making load decisions that actually build your business instead of just keeping you moving.
A low CPM only helps if your loads pay enough above it. Our dispatchers negotiate rates using your actual cost structure — not the industry average.
