A computing device for scheduling maintenance services for an earthmoving machine is disclosed. The computing device includes an input device configured to receive work hour input associated with work operations of the earthmoving machine and a visual display on board the earthmoving machine. The computing device further includes a processor configured to execute instructions for receiving the work hour input from the input device and determining current work hours associated with a completed maintenance service of the earthmoving machine based on the work hour input. The processor is further configured to execute instructions for presenting a user of the earthmoving machine, via the visual display, with one or more service interval rationalization options based on the current work hours and scheduling one or more subsequent planned maintenance services based on the one or more service interval rationalization options.
