The invention discloses a compensation calibration method and a compensation calibration device for an RTC module applied in an electric energy meter, wherein the compensation calibration method and the compensation calibration device relate to the technical field of electric power instruments. The compensation calibration method and the compensation calibration device settle a technical problem of low accuracy in a prior-art RTC module clock. The compensation calibration method comprises the steps of acquiring a compensation parameter which is required for clock calibration according to the measured crystal temperature of the RTC module; computing a compensation calibration value and a compensation remainder according to the compensation parameter and the least compensation unit of the RTC module; and calibrating the clock frequency of the RTC module according to the compensation calibration value and the compensation reminder.
