A heart rate estimating apparatus may include a transmitter to transmit microwave with respect to a subject, a receiver to receive and detect reflected wave from the subject irradiated with the microwave, and acquire a detected result, a sensor to sense a movement of the subject, and acquire a sensed result, and an estimating unit. The estimating unit may estimate a heart rate based on feature points remaining after excluding, from heart rate candidates, feature points that are obtained by frequency analysis of the detected result and are located in a vicinity of frequencies at which feature points are obtained by frequency analysis of the sensed result.
