Office 2021 vs Office 365

There is not much difference in the features of the apps included with these office suites except the cloud services offered in Office 365. One thing to keep in mind is that Office 2021 end of life is October 13, 2026, after which any new features that are released will be exclusive to Office 365.

A major point of difference between these apps is the payment plans on which they’re offered. Office 2021 is available as a one-time purchase whereas 365 works on a subscription-based payment plan that charges you either monthly or annually.

Office 365’s cloud capabilities go hand in hand with availability on other platforms like Android and iOS which takes file sharing, collaboration, storage, and file accessibility to a whole another level.

365 also allows you access to up to 5 devices on the basic personal plan whereas Office 2021’s basic plan allows access on just 1 PC or Mac.
