A method for monitoring the operating condition of a steam turbine, to which an adjustable inlet steam quantity can be supplied and from which a variable, partially expanded steam quantity can be extracted, includes initially ascertaining a relative inlet steam quantity for an adjustable inlet steam quantity as a percentage value, and ascertaining a relative turbine power from the relative inlet steam quantity as a percentage value; and determining an applicable operating point from the relative inlet steam quantity and the relative turbine power, and subsequently displaying the applicable operating point inside a performance graph for various extraction steam quantities. An apparatus for monitoring the operating condition of the steam turbine includes a final control element for adjusting the inlet steam quantity, a first device connected to the final control element for converting a position signal of the final control element into a percentage value of the corresponding inlet steam quantity, a second device connected to the first device for converting the percentage value of the inlet steam quantity into a percentage value of the turbine power, and a display device connected to the first and second devices. The display device has a screen on which a particular operating point determined by the relative inlet steam quantity and the relative turbine power can be displayed in a performance graph for various extraction steam quantities.
