A method is provided for determining the remaining service life of a rotor of a thermally loaded turboengine. In the method, a temperature on the rotor is determined, the thermal stress on the rotor is derived from the determined temperature, and the remaining service life of the rotor is deduced from the derived thermal stress. A simple, exact and flexible determination of the remaining service life is achieved in that the temperature is measured directly at a predetermined point of the rotor, and in that the thermal stress on the rotor is derived from the measured temperature.
