Every owner-operator runs this math eventually, usually at 2 a.m. in a truck stop parking lot. Here's the honest version of both columns — because the right answer depends on your savings, your risk tolerance, and how much unpaid office work you want.
What your own MC actually costs
The FMCSA filing fee is the cheap part. The real bill is insurance: new authorities routinely pay $12,000–$20,000 a year for liability and cargo coverage, often with a hefty down payment before the truck moves. Add a BOC-3 process agent, UCR registration, IRP plates, IFTA setup, a drug and alcohol consortium, and a compliance file you now maintain yourself.
Then comes the quiet cost nobody budgets: brokers. Many freight brokers won't touch an MC number younger than six to twelve months. Your authority can be perfectly legal and still spend its first year locked out of the best boards.
What leasing on costs instead
Under a lease-on program you run under the carrier's authority and insurance. You pay the carrier's program fee — commonly structured as a percentage of gross — plus the services you use, all of it itemized in the lease. In exchange, the six-figure insurance problem, the broker-age problem, and the back-office problem stop being yours.
The math question is simple to state: does the program fee cost less than what you'd spend (and lose) running your own authority? Take a hypothetical driver grossing $6,000–$8,000 a week under a fee of, say, 12% — that's real money. But so is $16,000 of insurance, a month of unbooked freight, and every evening spent invoicing. Run the numbers with the actual fee from the actual lease you're offered; that's the only version of this math that counts.
The break-even question to ask yourself
Own authority starts winning when you have six months of operating cash, established direct-shipper relationships, and genuine appetite for running a business on top of driving a truck. If any of those three is missing, the lease-on column usually wins on net income — not just on convenience.
Whichever way you lean, make the carrier show you their lease in writing before you commit. If the fee structure isn't on paper, the math you're doing is fiction.
