If it is renewed prior to expiration, maintenance costs 10% of the retail price of the software. If Maintenance is not renewed prior to expiration, a 1-year Maintenance Plan costs 15% of software list price and increases by 5% per year after the expiration date.

If your license is not currently on maintenance, you can pay the maintenance fee plus an expiration fee which will both upgrade you to the current version of the program AND include any upgrades that are released within the maintenance year.
