If there’s one version of Office that meets virtually all requirements while offering exceptional value for the money, it’s Microsoft Office 2021. Mature, stable, comprehensive, and with no ongoing subscription costs—Office 2021 is the best-selling version of Office at Lizenzindustrie. And for good reason. With us, you’ll receive your license immediately via email—at a price that’s up to 70% below the official list price.

Why Office 2021 Is the Best Choice for Most Users

Office 2021 strikes just the right balance for many users: It’s modern enough to meet all current requirements and mature enough to run reliably in any environment. No teething problems, no unexpected behavior—Office 2021 is a version that simply works.

The programs included in Office 2021 have undergone a number of genuine improvements that are immediately noticeable in everyday use. Word features a redesigned dark mode that makes long work sessions more comfortable, as well as improved collaboration when editing documents simultaneously. Excel impresses with new and powerful functions like XVERWEIS and XVERGLEICH, which significantly simplify complex queries, as well as the LAMBDA function, which lets you create your own formulas—a true milestone for anyone who regularly works with large datasets. PowerPoint introduces new transition effects and improved presentation tools, and Outlook runs faster and is more organized than ever before.

In addition, there’s a key advantage over a subscription: You make a one-time purchase and use Office 2021 permanently—with no monthly fees, no recurring payments, and no reliance on a stable internet connection.

Office 2021 Editions at a Glance

• Office 2021 Home & Student
• The entry-level version of Office 2021 includes Word, Excel, and PowerPoint—the three programs that are by far the most commonly used in everyday life. Ideal for high school and college students, as well as home users who use Office for homework, presentations, and everyday documents. No Outlook, no Publisher, no Access—but available at the lowest price.
• Office 2021 Home & Business
• Home & Business is the best-selling Office 2021 edition—and that speaks for itself. In addition to Word, Excel, and PowerPoint, it includes Outlook, the professional email client with a built-in calendar, task management, and contacts. For anyone who uses Office for work, works from home, or relies on effective email management as a self-employed professional, this edition is the top choice.
• Office 2021 Professional
• The full range of Office 2021 features in one package: Word, Excel, PowerPoint, Outlook, Publisher, and Access. Professional is designed for users and businesses that truly need all Office programs. With Publisher, you can professionally create flyers, newsletters, and marketing materials right within Office. Access offers a powerful database solution for the structured management of large amounts of data. If you want to get the most out of Office 2021, choose the Professional edition.

Office 2021 or Office 2024—is the extra cost worth it?

That’s a valid question, and here’s our honest answer: For the vast majority of users, Office 2021 makes no noticeable difference in daily use compared to Office 2024. If you use Word for documents, Excel for spreadsheets, and PowerPoint for presentations, Office 2021 offers everything you need—at a significantly lower price.

Office 2024 is worth it mainly if you specifically need the latest AI features, want to make targeted use of the improved Excel formulas, or generally want to stay up to date. For everyone else, Office 2021 is the smarter financial decision.

Office 2021 or Microsoft 365—which is the better choice?

Here, too, the answer is simple: it depends on how you use the software.

With Office 2021, you make a one-time purchase and use the software indefinitely—no subscription, no monthly costs, no surprises. For users who run Office on a single device and don’t need cloud services, this is the more affordable option in the long run.

Microsoft 365, on the other hand, offers other benefits: always the latest version of Office, 1 TB of cloud storage via OneDrive, the ability to use it on up to five devices simultaneously, and full Teams integration. If you work on multiple devices, collaborate with a team, or need cloud storage, Microsoft 365 is the better choice.
