Owner-Operator Net Income Calculator
Revenue per loaded mile minus fuel, maintenance, tires, tolls, truck and trailer notes, insurance, permits, and factoring — with realistic deadhead applied to the cost side only. Every default is sourced and every input is overridable.

How the model works
Owner-operator net income is gross revenue minus variable costs (costs that scale with miles) and fixed costs (costs that recur whether the truck rolls or not), minus factoring if used. Revenue accrues on loaded paid miles only; cost accrues on every mile the wheels turn, which is why the calculator treats deadhead as a cost-side multiplier, not a revenue reduction.
The default assumptions come from the American Transportation Research Institute's 2024 Analysis of the Operational Costs of Trucking, which uses 2023 fleet-reported data. ATRI's numbers are fleet averages — they slightly overstate the scheduled-maintenance cost for a single owner-op running a newer truck with warranty coverage, and slightly understate the cost of a single owner-op whose fleet-of-one can't negotiate tire or fuel discounts. Treat them as defensible starting points; if you have your own cost history, override the defaults.
Revenue-per-mile reality
The biggest input lever in this calculator is revenue per loaded mile. Line-haul rates shift with the freight cycle, with seasonality, with lane balance, and with equipment type. As of early 2026:
- Dry van spot market — roughly $2.00–$2.20 per loaded mile national average.
- Reefer — roughly $2.30–$2.60 per loaded mile, peak-produce premium higher.
- Flatbed — roughly $2.50–$2.80 per loaded mile, specialty flatbed higher.
- Tanker (food grade / chem) — usually $2.80+, with endorsement and cleanup requirements.
- Auto haul — wide range; specialty high-haulers can run $3.50+ but with equipment cost to match.
- Dedicated contract lanes — typically 10–25% above spot on the same equipment.
Before buying equipment, model the worst 10 weeks of the freight year (typically Jan–Feb post-holiday slack) at a rate 15–20% below the recent average and check whether the net still covers fixed costs. If it doesn't, you're planning to break a lease at some point — better to see it on paper than in a repo yard.
The deadhead lever
Owner-op freight is never truly 0% deadhead. Every load requires some bobtail or empty repositioning between drop and next pickup. Well-routed solo OTR runs 8–12% deadhead; regional runs 12–18%; specialty freight to thin-freight markets can hit 25%+. Each percentage point of deadhead adds miles to the fuel, maintenance, and tire lines without adding revenue — a 15% deadhead rate means every 1,000 paid miles actually burns 1,150 miles of cost.
Cost lines explained
Fuel — the biggest single variable
Fuel is modeled as total wheel miles ÷ mpg × diesel price. Diesel defaults to the EIA weekly national retail on-highway price. MPG defaults to 6.5 which is an honest on-highway fleet average for a late-model sleeper tractor pulling a 53-foot van; your actual number depends on aerodynamics, driving style, load weight, route topology, and truck condition. Trucks on governed cruise control with skirted trailers routinely do 7.5+ mpg; older flattop tractors or heavy-haul setups can see 5.5 or lower.
Maintenance, tires, tolls
These default to ATRI 2024: $0.200/mile maintenance, $0.044/mile tires, $0.034/mile permits + tolls. Maintenance includes scheduled PM (oil, filters, DEF, grease) plus wear items (brakes, clutch, starter, alternator). Tires are calculated as a per-mile amortization of drive-tire and trailer-tire replacement. Tolls are a national blend — lane-specific and can be very different on heavy-toll corridors like the I-90, I-95, I-80 stretches or the New York/New Jersey system.
Fixed costs
Truck payment, trailer payment, insurance, and permits-and-plates are fixed annual costs. They are paid whether you run 2,000 miles that week or 2,800. That's why weeks with mechanical downtime or weather cancellation hurt so much — fixed cost keeps running.
Factoring
Factoring is optional. Most first-year owner-ops factor because they don't have 30–45 days of working capital to wait on broker pay. The 2–3% factoring fee is cheaper than a credit card or a merchant cash advance. Once you have reserves and direct shipper contracts, drop the factoring and keep the full revenue.

Frequently asked questions
What should I keep in reserve as an owner-op?
A minimum of three months of fixed costs — roughly $15,000–$20,000 — to absorb one major repair event without financing it. Ideally six months.
Is it better to run under my own authority or under a carrier?
Running under a carrier's authority is simpler: the carrier handles compliance, billing, and broker relationships. Under your own authority you keep a larger share of gross but you also handle your own IFTA, MVR, CSA, drug program, and freight sourcing. Most owner-ops start under a carrier's authority and consider moving independent after 1–2 years of operational experience and capital.
Should I buy a new truck or a used one?
Used late-model (3–5 years, 350k–500k miles on a clean engine) gives the best ratio of lower payment to manageable maintenance. New trucks carry full warranty but a $3,500+ monthly payment that squeezes net in soft markets. Pre-emissions or pre-DEF trucks are cheaper to buy but may be restricted from California and emissions-tight markets.
How do owner-ops handle health insurance?
Health insurance is the largest hidden cost difference between company driving and owner-op. OOIDA (Owner-Operator Independent Drivers Association) offers group plans. Otherwise it's the individual ACA marketplace — typically $600–$1,400/month for a family depending on state and income. Build this into your annual fixed cost if you're modeling a serious career decision.
What's a realistic first-year net?
Under average market conditions with a solo OTR dry van running 2,500 paid miles per week for 50 weeks at $2.10/mile loaded, default inputs return a net in the $50k–$80k range before self-employment tax. The range is wide because fuel price swings, deadhead rate, and one unplanned major repair move the outcome significantly. Run the calculator against a weak-market scenario ($1.85/mile, $4.20 diesel) and a strong-market scenario ($2.35/mile, $3.50 diesel) to see the band.
