The Microsoft Office 2021 Mac Home & Business licence is a one-time purchase: no monthly fees, no automatic renewal. You pay once and can use the software offline on your Mac with lifetime access to modern Office apps including Word, Excel, PowerPoint, Outlook and OneNote.

Office 2021: Home & Business vs Professional Plus

Office 2021 Home & Business for Mac includes Word, Excel, PowerPoint and Outlook as a single purchase for macOS users. This version covers the essential productivity needs for individuals, students and small businesses using Mac computers.

Office 2021 Professional Plus is exclusive to Windows and adds Access for database management and Publisher for desktop publishing. This expanded suite serves larger organisations and users who require specialised business applications beyond the core Office programmes.

Office for Mac 2021 vs 2024: what are the differences?

Office 2024 for Mac offers extended Microsoft support, improved performance on newer macOS versions and compatibility with Apple Silicon processors (M2, M3 and later). The interface has been updated for better visual consistency across applications.

Office 2021 provides the same core functionality at a lower price, making it suitable for users who do not need the latest features or an extended support timeline. Office 2024 is recommended for users who want maximum longevity and compatibility with future system updates.

Office 2021 vs Microsoft 365: which to choose for Mac?

In this case we are not talking about two fundamentally identical suites but two very different products, both in terms of intended use and regarding costs and features. On one hand we have Office 2021 Home & Business for Mac, with one-time payment and possibility of unlimited offline use, on the other hand Microsoft 365, the most recent subscription plan for access to the Office suite and online collaboration. Let's see the characteristics in detail.

Ultimately, if you want a stable version of Office without paying every month, Office 2021 for Mac is the best option. But if you need cloud storage, group collaboration and frequent updates, Microsoft 365 is more flexible although it has ongoing costs over time.

Other versions of Office for Mac

If you are looking for a different version of Office for Mac with perpetual licence you can opt for the following options:

• Office 2016 for Mac – earlier version at a lower price
• Office 2024 for Mac or Office 2024 Home & Business – more recent functionality and supported for longer
