What is rate per mile (RPM) in trucking?

Rate per mile (RPM) is the amount a carrier earns per loaded mile of freight transport. It's calculated by dividing the total gross pay for a load by the number of loaded miles. For example, a load that pays $1,800 for 900 miles has a gross RPM of $2.00. RPM is the primary metric dispatchers use to compare load profitability across different lanes and distances.

What is the difference between gross RPM and net RPM?

Gross RPM is the broker's posted rate divided by loaded miles — what the carrier earns before expenses. Net RPM is what remains after subtracting all costs: fuel, driver pay, insurance, truck payment, and overhead. A load at $2.00 gross RPM might yield $1.15 net RPM after $0.85 in per-mile costs. Dispatchers should evaluate loads on net RPM, not gross — a high gross rate on a long deadhead lane can yield less net than a lower gross rate with zero deadhead.

What is a good rate per mile for trucking in 2025?

Good net RPM benchmarks by equipment type in 2025: Dry Van — $1.10–$1.40 net; Reefer — $1.35–$1.75 net; Flatbed — $1.40–$2.00 net (standard); $3.00–$5.00 for oversize; Power Only — $1.00–$1.40 net; Hotshot — $1.20–$2.00 net; Box Truck — $0.80–$1.20 net. These are benchmarks for well-run operations — market conditions, fuel price, and lane supply/demand all affect what's achievable at any given time.

How do I calculate my floor rate per mile?

To calculate your floor rate: (1) Add all fixed monthly costs — truck payment, insurance, trailer payment, ELD subscription, and other fixed expenses; (2) Add variable costs per mile — fuel (total miles × fuel cost ÷ MPG), tires (estimated per mile), maintenance (estimated per mile); (3) Add driver pay per loaded mile; (4) Divide total monthly costs by expected loaded miles per month; (5) Add your target profit margin. The result is your per-mile floor rate — any load below this rate doesn't cover costs.

How does fuel price affect rate per mile?

Fuel is typically 25–35% of total operating cost for a trucking operation. At $4/gallon diesel and 6.5 MPG, fuel cost is $0.615/mile. At $3/gallon, it's $0.461/mile — a $0.154/mile difference. On a 500-mile load, that's $77 difference in fuel cost. Dispatchers should update their floor rate calculation when diesel prices move significantly, and prefer loads in the direction of lower fuel prices when possible.

What is RPM in trucking vs trucking average RPM?

RPM in trucking refers to rate per mile — not revolutions per minute as in engines. The national average dry van truckload rate per mile fluctuates with market conditions; in 2024–2025, spot market dry van averaged $1.90–$2.20 gross RPM depending on the season and region. Contract rates tend to be $0.10–$0.30 lower than spot rates but are more predictable. Net RPM after costs typically runs $0.60–$1.00 below gross RPM depending on the carrier's cost structure.

Rate Per Mile in Trucking: Gross vs Net RPM Explained

DispatchOS AI Editorial · September 2025 · 6 min read

Rate per mile (RPM) is the primary metric freight dispatchers use to evaluate load profitability. But gross RPM — the number a broker posts — and net RPM — what actually reaches the carrier's bank account — are very different numbers. Understanding the gap between them is the foundation of profitable dispatch.

Gross RPM vs Net RPM

Gross RPM is simple: total load pay ÷ loaded miles. A load paying $1,900 for 900 miles = $2.11 gross RPM. That's what the broker offers.

Net RPM is what matters: gross RPM minus all per-mile costs. For a typical dry van operation:

Example cost structure: Fuel: $0.55/mi · Driver: $0.42/mi · Truck payment: $0.12/mi · Insurance: $0.10/mi · Maintenance/tires: $0.08/mi · Overhead: $0.05/mi · Total costs: $1.32/mi

At $2.11 gross RPM − $1.32 costs = $0.79 net RPM. Not $2.11.

The difference is why two loads with similar gross RPM can have dramatically different profitability — fuel efficiency, driver pay structure, and whether deadhead is included all change the net calculation significantly.

Net RPM Benchmarks by Equipment Type

Equipment	Target Net RPM	Notes
Dry Van	$1.10–$1.40	Competitive market; efficiency-driven
Reefer	$1.35–$1.75	Higher costs (reefer fuel); higher rates compensate
Flatbed (standard)	$1.40–$2.00	Securement and tarping increase costs
Flatbed (heavy haul)	$3.00–$5.00+	Permit costs and complexity priced in
Power Only	$1.00–$1.40	Lower costs (no freight liability); lower rates
Hotshot	$1.20–$2.00	Pickup truck fuel economy reduces margin vs semi
Box Truck	$0.80–$1.20	Regional/last-mile; higher stop volume compensates

How to Calculate Your Floor Rate

Your floor rate is the minimum net RPM that covers all costs with zero profit. Any load below the floor is a money-loser. Here's how to calculate it:

Fixed monthly costs: Truck payment + insurance + trailer payment + ELD + other fixed items (e.g., $3,500/month)
Variable costs per mile: Fuel (total miles × fuel cost ÷ MPG) + tires + maintenance (estimate $0.10–$0.15/mile combined)
Driver pay per mile: Your pay rate or what you pay your driver
Divide total monthly cost by expected loaded miles: $3,500 fixed ÷ 8,000 loaded miles = $0.44/mile fixed cost contribution
Add variable costs + driver pay: Total per-mile cost = your floor
Add target margin: Floor + desired profit = minimum acceptable gross RPM

Why Fuel Price Changes Your Floor Rate

Diesel price is the largest single variable in carrier economics. At $4.00/gallon and 6.5 MPG, fuel cost is $0.615/mile. At $3.50/gallon, it's $0.538/mile — a $0.077/mile difference. Across 10,000 miles per month, that's $770/month difference in fuel cost. Floor rates should be recalculated quarterly at minimum, and immediately when diesel prices move more than $0.50/gallon.

The Deadhead Adjustment

Gross RPM is quoted on loaded miles only. Deadhead miles cost fuel without revenue. A load at $2.00 gross RPM with 150 miles of deadhead is actually:

$2.00 × 800 miles = $1,600 gross ÷ (800 loaded + 150 deadhead) = $1.68 adjusted RPM. The 150 deadhead miles cost roughly $0.45/mi × 150 = $67.50 out of the $1,600 gross.

What is RPM in trucking?

RPM means rate per mile — the amount a carrier earns per loaded mile. Gross RPM is the broker's posted rate. Net RPM is what remains after all costs. Net RPM is what matters for profitability.

What is a good rate per mile for trucking?

Good net RPM targets: Dry Van $1.10–$1.40, Reefer $1.35–$1.75, Flatbed $1.40–$2.00 standard, Power Only $1.00–$1.40, Hotshot $1.20–$2.00, Box Truck $0.80–$1.20. Market conditions and fuel prices affect what's achievable.

How do I calculate my minimum rate per mile?

Add all monthly costs (fixed + variable + driver pay), divide by expected loaded miles, add your target profit margin. That's your minimum gross RPM. Any load below it doesn't cover costs.
