An odometer data computing apparatus includes an odometer data computer device and a printer. The computer device includes a keypad, liquid crystal display, microcomputer electronics and continuous memory to record beginning and end of trip time, dates, and odometer readings, to separate pleasure trip mileage, from business mileage, to compute the business mileage for each trip up to sixty business trips at a given time, to accumulate the total business trip mileage for the year, to end the yearly record promptly at the end of the year by indicating a need to print out the trip information for the year, to store the total mileage for the previous year, and to continue the trip recording for the next year. Trip information, including total mileage information for the previous year, may be printed out at any time during the current year. Also, trip information for each trip currently in memory may be printed out at any time.
