A method determines the combined center of gravity for a materials-handling vehicle and its payload. The method picks up the payload, positions the payload to a first height; subjects the vehicle to a first acceleration force, determines a first pressure in a tilt cylinder, positions the payload to a second height, subjects the vehicle to a second acceleration force, determines a second pressure in the tilt cylinder, and calculates a position of the combined center of gravity of the materials-handling vehicle and the payload. A materials-handling vehicles incorporates a mast, a lift carriage configured to move a payload vertically, a tilt cylinder configured to tilt the mast, a pressure sensor configured to measure a pressure within the tilt cylinder, and a processor configured to calculate a position of the combined center of gravity of the materials-handling vehicle and the payload.
