Microsoft Office 2021 vs Microsoft 365: Key Differences Explained

Is Microsoft Office Worth the Price?

The initial cost of getting Microsoft Office might be a little more than your monthly subscription to Microsoft 365, but you’re only paying once. Ever. After that, you’ve got Word, Excel, PowerPoint, Outlook, Teams, OneNote, Publisher, and Access for life. Install them on one computer and that’s it. Use these apps at work or at home. They’re yours.

The main difference between Microsoft 365 and Microsoft Office 2021 is the version of your apps. 365 has the most recent. Office 2021's are from 2021, but they still perform much the same.
