The business model — where the money actually comes from
Line-item revenue and expense breakdown of a real single-truck box truck business, with the four hidden costs new carriers always miss.
The business model in one paragraph
You buy or finance a 26' straight truck. You get MC authority so brokers can legally tender you loads. You bind commercial auto and cargo insurance. You use a load board or Amazon Relay to book freight. You run the load, invoice the broker, factor the invoice for 24-hour pay, buy fuel with the fuel card, pay yourself what's left. That's it.
The whole game is in the margins.
Real revenue — one truck, one driver (you), 2026 numbers
Here's a representative month from my second truck (dry van 26' Isuzu FTR, running mostly Midwest regional):
| Line | Amount |
|---|---|
| Amazon Relay dedicated (2 lanes, 5 days/week) | $6,800 |
| Spot loads (DAT, ~8 loads) | $8,200 |
| Detention & lumper reimbursements | $340 |
| Gross revenue | $15,340 |
Now the costs.
Real expenses — same month
| Line | Amount |
|---|---|
| Fuel (~4,100 miles @ 8.5 mpg, $3.85/gal) | $1,857 |
| Truck payment (used, $52k @ 9.9% / 60 mo) | $1,103 |
| Commercial auto insurance | $625 |
| Cargo & general liability | $135 |
| Physical damage insurance | $180 |
| Maintenance reserve ($0.12/mi) | $492 |
| Tire reserve ($0.03/mi) | $123 |
| Factoring (2.5% of $15,340) | $384 |
| ELD, DAT, QuickBooks, phone | $260 |
| IFTA reserve | $210 |
| Tolls, scales, parking | $180 |
| Accountant retainer | $150 |
| Total operating cost | $5,699 |
Net to owner
$15,340 gross − $5,699 opex = $9,641 net for the month.
That's a good month, not an exceptional one. A bad month with a two-day breakdown looks more like $6,200 net. A great month with a hot lane hits $12,000+.
The four hidden costs new carriers always miss
- 1The maintenance reserve you never funded. New carriers pocket the "extra" cash in month 1–3 because the truck runs fine. Month 4 an alternator goes ($800), a DPF regen fails ($1,400), you eat two rear tires on a curb ($900), and suddenly you can't make truck payment. Set aside $0.12–$0.18 per revenue mile the day the money hits, before you touch it.
- 1Deadhead miles. You get a $2,200 load, 500 miles. Great! Except pickup is 200 miles from your delivery of the last load. Effective rate: $2,200 ÷ 700 = $3.14/mi loaded but $2,200 ÷ 500 = $4.40/mi if you don't count deadhead. You're not lying to a broker — you're lying to yourself. See the lesson on deadhead math.
- 1Detention that never gets paid. Brokers will promise detention. Most will fight you on paying it. Assume the first $2/hr of "promised" detention at any shipper is fiction unless you have it in writing on the rate confirmation.
- 1The IFTA hit at the end of the quarter. You buy cheap fuel in a cheap-tax state (like Oklahoma) and run miles in an expensive-tax state (like Pennsylvania or California). At quarter end IFTA settles the difference — and it's usually a bill, not a refund. Reserve ~$0.03–$0.05/mi.
Where owners actually leak money
In order of biggest leak to smallest, from what I see auditing new-carrier books:
- 1Running cheap loads because they exist (not because they pay).
- 2Deadheading > 100 miles for a "great" rate that isn't great after deadhead.
- 3Skipping preventive maintenance to "save money" — then paying 4x on the roadside.
- 4Not factoring, then floating a $12k receivable and missing truck payment.
- 5Buying a truck at auction with no PPI (see the PPI lesson — you can't skip this).
Homework
- Open the Cost-per-mile calculator in the Tools section.
- Plug in a truck you're considering (or your existing truck).
- Write down your CPM. Screenshot it. That number rules every future decision.
