How does a perpetual license differ from an annual license?

A perpetual license offers ongoing access to the NumXL software without the need for future renewals, whereas an annual (subscription) license provides users with one year's access to the software at a reduced price. Both licenses provide one year of free Premier support; at the end of the first year, users with a perpetual license can renew their support for a small fee.
