The most common pay models in auto transport are per-mile, percentage of load revenue, and salary — and each one produces a fundamentally different business dynamic. Per-mile pay is simple and predictable for drivers but disconnects their earnings from load value. Percentage pay aligns driver income with your revenue but requires tight load rate management. Salary is rare in trucking but sometimes used for owner-operators converting to employee status or for dispatchers who also drive. Most small-to-mid fleets in the US and Canada run some variant of percentage or per-mile, often with a fuel surcharge component layered on top.
There is no single right answer. Your ideal model depends on whether you run company drivers or owner-operators, how consistent your lane rates are, how much administrative overhead you can absorb, and what CRA (Canada Revenue Agency) or IRS classification rules look like for your workforce. This guide walks through each model with real numbers, the tradeoffs, and what compliance obligations attach to each one.
Per-Mile Pay
Per-mile is the oldest and most transparent model. You agree on a cents-per-mile (CPM) rate with each driver, and they earn that rate for every loaded mile — sometimes for deadhead miles too, at a reduced rate. A common range for company drivers in auto transport is $0.55–$0.80 USD per loaded mile in the US, and $0.65–$0.90 CAD per loaded mile in Canada depending on province and carrier size.
When it works
- You run consistent lane distances and load values are similar across loads.
- Drivers are W-2 employees (US) or T4 employees (Canada) and you want a simple payroll calculation.
- You dispatch short regional routes where percentage pay would yield very low gross.
When it breaks down
- Load rates vary significantly — a $1,200 load and a $2,400 load over the same 400-mile lane pay the driver identically. You absorb the difference, which can hurt on broker loads with thin margins.
- Drivers have little incentive to handle high-value loads with extra care, because pay does not reflect load complexity.
- Fuel surcharge pass-throughs become a separate calculation unless you bake them into the CPM rate.

Percentage of Load Revenue
Percentage pay ties driver compensation directly to what the load bills. A driver who hauls a load that invoices at $1,800 and earns 28% takes home $504 on that load. Industry norms for auto transport company drivers run 25–32% of gross load revenue in the US; Canadian operators typically see similar ranges, though provincial minimum wage rules set a floor you must audit quarterly.
Typical percentage ranges
| Driver type | Typical range (US) | Typical range (Canada) |
|---|---|---|
| Company driver, 9-car open | 25–30% | 25–30% |
| Company driver, enclosed | 28–33% | 28–33% |
| Owner-operator (leased on) | 70–80% of line-haul | 70–80% of line-haul |
When it works
- Load rates fluctuate — drivers share upside on strong loads and you are partially protected on low-rate loads.
- You want to reward drivers who accept difficult loads (multi-stop, enclosed, oversized) naturally without a separate bonus structure.
- Owner-operators leased to your authority: percentage is standard industry practice and aligns with how most broker sheets calculate settlement.
The compliance risk you must manage
In Canada, the percentage model must still meet provincial minimum wage thresholds on a per-period basis. If a driver works 60 hours in a week and their percentage earnings divide out below provincial minimum, you owe a top-up. CRA audits increasingly scrutinize percentage-pay arrangements where drivers are classified as independent contractors — if you control their schedule, dispatch, and equipment, CRA may reclassify them as employees regardless of the contract language. In the US, the DOT and FMCSA do not dictate pay model, but the IRS worker classification rules (common law test) apply similarly.
Salary and Hybrid Models
True salary — a fixed weekly or biweekly amount regardless of loads hauled — is uncommon in auto transport. It appears most often when a fleet converts an owner-operator to a W-2 (US) or T4 (Canada) employee, or when a driver also holds a dispatch or yard management role. Salary removes income variability for the driver, which can aid retention, but it removes the productivity incentive entirely and creates overtime exposure under the Fair Labor Standards Act (FLSA) in the US, and the Canada Labour Code or provincial employment standards acts for federally or provincially regulated carriers.
More practical than pure salary are hybrid models: a guaranteed minimum base (a floor per load or per week) plus a percentage above that floor. For example, a driver is guaranteed $1,200 per week minimum, and earns 27% of gross load revenue — whichever is higher. This protects drivers during slow weeks and removes the minimum-wage compliance liability from percentage-only arrangements.
Owner-Operator vs. Company Driver: The Classification Line
Pay model and worker classification are separate questions, but they interact. An owner-operator who leases onto your carrier authority under a lease agreement is typically paid 70–80% of line-haul revenue. They invoice you (or you settle them), and they are responsible for their own fuel, truck payments, insurance, and self-employment taxes.
In Canada, owner-operators under a carrier services agreement are generally treated as self-employed for CRA purposes, but the NSC (National Safety Code) and provincial transport authorities (such as Ontario's MTO or BC's CVSe under the CVOR program) still hold the carrier responsible for the operator's safety compliance. In the US, FMCSA lease regulations (49 CFR Part 376) govern the lease agreement terms, including the settlement statement requirements — you must provide an itemized settlement showing gross revenue, any charge-backs, and the net amount paid.
Misclassifying a company driver as an owner-operator exposes you to back payroll taxes, penalties, and potential EI/CPP (Canada) or FICA (US) liability going back three years. If you are unsure about any driver's classification, a two-hour consultation with a transportation-focused employment lawyer is almost always worth the cost.
Fuel Surcharge: Who Absorbs It?
Fuel surcharge (FSC) handling is one of the most contentious points in driver pay. Common approaches:
- Bake FSC into the base rate: Simpler, but driver earnings do not adjust when diesel prices spike. Works best with stable fuel markets.
- Pass FSC through on percentage pay: If FSC is billed to the customer and included in gross invoice, and you pay 28% of gross, the driver benefits automatically. Verify your broker agreements — many brokers strip FSC before calculating carrier pay.
- Separate FSC line on settlement: You pay a fixed per-mile FSC (e.g., $0.08/mile) on top of percentage or CPM pay. This is the most transparent and the easiest to audit during a CRA or IRS review.
For Canadian operators, diesel prices vary significantly between provinces. A driver deadheading through BC pays materially more per litre than one running through Saskatchewan. If you have owner-operators or company drivers running cross-provincial lanes, a fuel-table-based FSC that updates weekly is more defensible than a flat rate.
What to Track — and Why It Matters at Settlement
Regardless of which model you choose, you need to produce an accurate, itemized settlement statement every pay period. At minimum, each settlement should show:
- Load ID, origin, destination, and delivery date
- Gross load revenue (or loaded miles, for CPM)
- Pay rate applied (percentage or CPM)
- Gross driver earnings before deductions
- Itemized deductions (fuel advances, insurance, escrow if applicable)
- Net pay
Under FMCSA lease rules (US) and most provincial carrier regulations (Canada), owner- operator settlements must be produced within a defined period — typically within 15 days of the load delivery. Company driver settlements must align with provincial or federal payroll cycle rules.
Managing settlements manually across 5–15 drivers across multiple load types and pay models is where spreadsheets consistently fail operators — not because of math errors alone, but because version control and audit trail are non-existent. When CRA or the IRS requests payroll records, you need a timestamped record for every settlement, not a shared Excel file. AutoHauler AI's driver pay module generates settlement statements automatically from dispatched loads, applying your configured pay model per driver so every payout is documented and exportable.
Choosing the Right Model for Your Fleet
A practical starting point: if your loads are consistently priced and you run company drivers on regional lanes, per-mile with a separate FSC line is the simplest compliant structure. If you run broker loads with variable rates, or you want drivers incentivized on load quality, percentage pay aligned to your invoiced gross is more appropriate. If you are bringing on your first owner-operator, use a written lease agreement and settle at 70–75% of line-haul with a separate FSC table.
Review your pay model annually — fuel prices, broker rate compression, and provincial minimum wage changes (Canada sees adjustments in several provinces each October 1) can all shift whether your current model is still competitive and compliant.
