Annual contract, paid monthly vs Month to month

Ok thanks for good answers.

Even If you need Cretive Cloud for a month, then you can cancel Annual contract any time and pay less.
Where is the catch?

The catch is the early termination fee on the annual contract when you cancel before 12 months expires.

Example scenarios, in the US, you will normally pay (excluding special offers):

< 6 months: Month by Month is cheaper

> 6 months: Annual plan is cheaper

Annual plans require a 12 month commitment.  And your rate is guaranteed for the entire year.

Month-to-month plans do not require any commitment.   You can cancel anytime without incurring a penalty fee -- good for people who only need the app for 1-3 month projects.  But the rate is subject to increase.

Different plans for different users.
