In a Class B network, the address space allocates 16 bits for host IDs. The formula to calculate the number of available host IDs is 2^n - 2, where n is the number of bits. For Class B, it's 2^16 - 2, which equals 65534. The subtraction of 2 accounts for the network address and the broadcast address, which cannot be assigned to hosts.
