 You can use your own numbers to calculate an hourly rate to compensate for lost income opportunity, as well as fixed costs, which don't stop when the truck stops. Those two elements of a fair detention rate were deemed appropriate by most of Overdrive's audience almost a decade ago. We've used income, fixed costs, and miles average of our owner-operator business services from ATBS's clients to compute an average $64 an hour detention rate then. And 10 years later, the figure is $83 an hour.
