How Much Is Your Iron? (German: Was kostet das Eisen?) is a short play by German modernist playwright Bertolt Brecht. Brecht wrote How Much Is Your Iron? in [1939] while in exile in Sweden, against the background of the approaching Second World War, following Nazi Germany's annexations of Austria and Czechoslovakia, against which Western powers such as Great Britain and France had at that stage not yet intervened. The play takes a critical look at Sweden's involvement with both Axis and Allied Powers in the build-up to World War Two.
