How to Calculate Rate Per Mile for Trucking

The basic rate-per-mile formula

Gross rate per mile equals total load revenue divided by total trip miles. Total trip miles must include loaded miles and deadhead miles,not only the miles shown on the rate confirmation.

Example: a load pays $2,400, runs 900 loaded miles, and requires 100 deadhead miles. The true gross RPM is $2,400 ÷ 1,000 miles = $2.40 per mile. Using only loaded miles would show $2.67 and overstate the load.

Revenue that belongs in the calculation

• ✓ Linehaul pay
• ✓ Fuel surcharge
• ✓ Detention and layover pay
• ✓ Stop pay and accessorial pay
• ✓ Reimbursed lumper fees,tracked separately so reimbursements do not look like profit

Calculate net rate per mile

Net RPM shows what remains after variable trip expenses. Subtract fuel, tolls, scales, parking, lumpers not reimbursed, and other load-specific costs from total revenue. Then divide the result by total miles.

For the $2,400 load above, assume $650 in trip expenses. Net trip contribution is $1,750. Divided by 1,000 total miles, net RPM is $1.75 before fixed costs such as insurance, truck payment, permits, and office expenses.

Know your break-even rate

Add your monthly fixed costs and expected variable costs, then divide by realistic monthly miles. If fixed costs are $6,000, variable costs are $0.95 per mile, and the truck runs 10,000 miles, break-even is $1.55 per mile before owner pay and profit.

Your target rate must sit above break-even and include a margin for maintenance reserves, downtime, taxes, and owner compensation. A load can look attractive on loaded RPM and still lose money after deadhead and fixed costs.

Use the same method on every load

• ✓ Record odometer or verified route miles at dispatch and delivery
• ✓ Separate loaded and deadhead miles
• ✓ Capture accessorial revenue when earned
• ✓ Attach trip-specific expenses to the same load
• ✓ Compare gross RPM, net RPM, and total profit,not RPM alone
