What Makes a Load Profitable? Fuel, Driver Pay, and the Hidden Math

Every dispatcher gets the same call from a broker: '$2.10 per mile, 800 miles, ready today.' Sounds great. Feels great. Book it, drive it, invoice it.

Then payroll runs, fuel receipts come in, and somehow that load lost you $180. What went wrong?

The 5 hidden costs

• Deadhead miles to pickup (often 50-150 miles paid nothing)
• Deadhead miles back from delivery (or to next load)
• Fuel spread (diesel at destination vs. origin)
• Driver percentage (usually 25-30% of revenue)
• Detention risk (delays that eat driver hours-of-service)

Let's run the actual math

800 miles at $2.10 = $1,680 revenue. Feels like $1,680 in your pocket. It isn't.

• Deadhead 120 miles pickup + 80 miles from delivery = 200 miles unpaid
• Total mileage on truck: 1,000 miles
• Effective rate per truck mile: $1.68
• Fuel @ 6.5 mpg × $4.20/gal = $645
• Driver 27% of gross = $454
• Insurance/registration allocated per load ≈ $75
• Maintenance reserve ($0.15/mile) = $150
• Total costs: $1,324
• Net profit: $356 (before overhead like dispatcher time)

That's a real $356 — solid, not spectacular. But now imagine your driver hits 3 hours of detention at the receiver:

• Driver still gets paid: +$50
• Hours-of-service lost — next load must be shorter or pushed = $250 opportunity cost
• Net now: $56

The rule of thumb

If deadhead is over 20% of paid miles, or if the fuel spread is over $0.15/gal against you, or if the load has known detention risk — bump your minimum rate to $2.40+/mile.

"Bad loads don't feel bad in the moment. They only feel bad when payroll runs. That's why every load offer should get 30 seconds in a real profit calculator BEFORE you say yes."
