Every owner-operator has been there: a load broker calls with what sounds like a great rate, and you need to decide in minutes whether to take it. Most drivers do quick mental math, but quick mental math leaves money on the table — and sometimes puts you in the red without realizing it.

Here's how to calculate true load profitability before you commit.

Step 1: Know Your Total Miles

Most drivers focus on loaded miles, but your fuel cost doesn't care whether you're full or empty. Deadhead miles to the pickup location cost the same per gallon as loaded miles. Always start your calculation with total miles = loaded miles + deadhead miles.

If you're currently in Chicago and the pickup is in Gary, Indiana (about 30 miles), and the load runs to Dallas (915 miles), your total trip is 945 miles — not 915.

Step 2: Calculate Your Fuel Cost

Divide total miles by your truck's MPG to get gallons needed. Then multiply by today's diesel price.

Example:

Total miles: 945
MPG: 6.5
Gallons needed: 145.4
Diesel price: $3.85/gallon
Fuel cost: $559.77

This is real money coming out of your pocket before you earn anything else.

Step 3: Calculate Revenue Per Mile

Divide the offered rate by your total miles. This is your revenue per total mile (RPM) — the single most important profitability metric in trucking.

Example:

Offered rate: $2,200
Total miles: 945
RPM: $2.33/mile

A general rule of thumb:

$2.50+/mile: Great
$2.00–$2.49/mile: Good
$1.50–$1.99/mile: Marginal
Below $1.50/mile: Usually not worth it

Step 4: Subtract Your Operating Costs

Fuel is only one expense. Your truck has payments (or depreciation), insurance, tires, maintenance, and permits. Most owner-operators in dry van have operating costs of $0.45–$0.65 per mile beyond fuel.

Example:

Operating cost: $0.55/mile × 945 miles = $519.75
Fuel cost: $559.77
Total costs: $1,079.52
Offered rate: $2,200
Net profit: $1,120.48

Step 5: Account for Time

A 945-mile load might take 14 hours of drive time plus loading, waiting, and unloading. If that puts you at 20 hours of total time on the clock, you've effectively earned $56/hour — before your own time has any value.

Compare that to a shorter, higher-RPM load that takes 8 hours. The numbers often tell a different story than the gross rate suggests.

Use Haulalytics to Automate This

Doing this math manually for every load is tedious. Haulalytics automates all of it: enter the pickup location, delivery, offered rate, and your truck specs — and get instant results including fuel cost with real-time prices, RPM, and a profitability score.

The calculator also supports deadhead mile tracking and side-by-side load comparison, so you can choose the better of two loads in seconds.

The Bottom Line

The drivers who build wealth in trucking aren't just the hardest workers — they're the ones who say no to bad loads quickly and yes to great ones confidently. Knowing how to calculate load profitability is the single skill that separates sustainable owner-operators from those who are always struggling to break even.
