A method for determining the amount of laundry in a laundry treating appliance comprises a drum defining a treating chamber for receiving the laundry and a motor for rotating the drum that may be operated to simulate a spring to oscillate the drum relative to a predetermined rotational position. The angular decay of the drum relative to the predetermined position may be determined and used to determine the amount of laundry.
