Springs with closed ends or with closed and ground ends have one inactive coil at each end. Springs with open ends are considered to have virtually no inactive coil. Springs with open ends ground are considered to have about one-half inactive coil at each end. The active coils are what make a spring a spring. The active term should really be applied to any portion of a spring that stores and releases energy.
