Quick answer
Rate per mile (RPM) is the load’s pay divided by miles. The honest version divides by all miles, including deadhead: the empty miles driven to reach the pickup. A load that looks strong on loaded miles can be weak once deadhead is counted.
What is deadhead?
Deadhead is driving with an empty trailer, usually from a delivery to the next pickup. You still pay for fuel, wear, and time on those miles, but most loads only pay for loaded miles.
How to calculate all-in rate per mile
Step 1: Add the miles
Loaded miles plus deadhead miles to the pickup.
Step 2: Take the total pay
Linehaul plus any confirmed accessorials.
Step 3: Divide
Total pay ÷ total miles = all-in rate per mile.
Step 4: Compare
Check the result against your cost per mile and target margin.

| Item | Load A | Load B |
|---|---|---|
| Pay | $2,000 | $1,800 |
| Loaded miles | 800 | 750 |
| Deadhead miles | 200 | 30 |
| Loaded-mile RPM | $2.50 | $2.40 |
| All-in RPM | $2.00 | $2.31 |
Look at the next load too
Where a load delivers matters as much as what it pays. A delivery into an area with few outbound loads can mean long deadhead or waiting, so good dispatching weighs each load against the likely next one.
