How to calculate rate per mile
Rate per mile (RPM) is the load's linehaul rate divided by miles. The only question is which miles.
Posted RPM = rate ÷ loaded miles
All-in RPM = rate ÷ (loaded miles + deadhead miles)
A load board shows posted RPM because the loaded miles are all it knows. Your truck also drives the empty miles to the pickup, and burns fuel on them. All-in RPM is what the load pays for every mile the truck actually turns.
A worked example
A Dallas to Atlanta van load pays $2,190 for 785 loaded miles. Posted, that is $2.79 a mile. The truck sits 42 miles from the pickup, so it drives 827 miles in total and the load really pays $2.65 a mile. Put the same truck 245 miles away and the identical load drops to $2.13.
What counts as a good rate per mile?
There is no single number. Rates move with the season, the lane and the equipment, and a rate that works for one truck loses money for another. The useful test is your own: a load is worth booking when its all-in RPM covers your cost per mile plus the margin you need.
To find your cost per mile, add up a typical month of fuel, driver pay, insurance, truck and trailer payments, maintenance and permits, then divide by the miles the truck drove that month. Keep that number next to the board, or let LoadBit carry it for you.
Why deadhead matters more than it looks
Deadhead miles cost the same fuel and time as loaded ones and pay nothing. On a 400-mile haul, 100 empty miles take a fifth off the real rate. Checking all-in RPM before you bid is the quickest way to stop a good-looking rate from turning into a bad week.
