Why is formatted capacity less?

In each formatting scheme, a portion of the storage space is allocated to catalog the data on the drive. This process enables the computer or another device to read and write the data to the drive correctly. When a drive is formatted, the functional storage space of the drive is less than its unformatted capacity.
