How is the price of Carlson maintenance calculated?

Updated 9/1/2019: Carlson announced that they are increasing prices for maintenance renewals as of 9/1/2019 – you can view this as a PDF here.

If it is renewed prior to expiration, the price will remain the same – 10% of the retail price of the software.

However, if Maintenance is not renewed prior to expiration, a 1-year Maintenance Plan costs 20% of software list price and increases by 10% per year after the expiration date.

But, regardless of how many years you’ve fallen behind, Carlson will never charge more than 50% of the current retail price of the software in order to bring your license up to the current version.

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.
