ESC is built on top of an anti-lock brake (ABS) system. The ESC components include a Yaw rate sensor, a Lateral Acceleration Sensor, a Steering Wheel Sensor, and an upgraded Integrated Control Unit. According to National Highway Traffic Safety Administration research, ABS costs an estimated US$368 (in 2005) and ESC costs an additional US$111. The retail price of ESC varies; as a stand-alone option, it retails for as little as $450. Unfortunately, many auto makers bundle ESC with other features so the cost of a package that includes ESC could be several thousands of dollars.

ESC is highly cost-effective[14] and it might pay for itself in reduced insurance premiums.

ESC is not generally available for after-market installation. The only way consumers can get ESC is to buy a vehicle equipped by the manufacturer with standard or optional ESC.
